Performance characteristics of the unit

Use conditions of the unit

The air-cooled heat pump modular unit is composed of one or more modules. Each module has its own independent electric

control unit, and the electric control units of modules conduct information exchange through communication network. The

air-cooled heat pump modular unit is characteristics of compact structure and easy transportation and lifting, and in the meanwhile,

it also saves facilities, including cooling tower, cooling pump, and so on, for the user, and reduces installation cost.

The units provide central air handling devices or terminal equipment with chilled water or hot water. The unit is a completely

independent entirety type one, which is designed to be installed outdoors (on the ground or the roof). Each unit includes such main

parts as high-efficient and low-noise scroll compressor, air-cooled condenser, shell and tube (or plate) evaporator, micro-computer

control center, and so on. These parts are installed on steel structure base, so they are sound and durable.

The unit applies Chinese micro-computer control system, which can automatically conduct energy control according to the

magnitude of load, to achieve optimal matching and thus actually realizing optimal energy-saving operation. The product is

modularized unit, and parallel connection of 16 modules can be realized at most, so the user can adopt module combination

according his own demands. The product can be widely applied in air-conditioning engineering of various newly-built and rebuilt

industrial and civil buildings, such as restaurant, hotel, apartment, office building, hospital, industrial plant, and so on. The

air-cooled heat pump modular unit is the best choice for the place which has high requirement in noise and ambient environment

and which is short of water.

installation & owner’s manual

1. PRECAUTIONS

To prevent injury to the user or other people and property

damage, the following instructions must be followed. Incorrect

operation due to ignoring of instructions may cause harm or

damage.

Ask your dealer for installation of the air conditioner.

Incomplete installation performed by yourself may result in a

water leakage, electric shock, and fire.

Ask your dealer for improvement, repair, and maintenance.

Incomplete improvement, repair, and maintenance may

result in a water leakage, electric shock, and fire.

In order to avoid electric shock, fire or injury, or if you detect

any abnormality such as smell of fire, turn off the power

supply and call your dealer for instructions.

Never replace a fuse with that of wrong rated current or

other wires when a fuse blows out.

Use of wire or copper wire may cause the unit to break down

or cause a fire.

Do not insert fingers, rods or other objects into the air inlet or

outlet.

When the fan is rotating at high speed, it will cause injury.

Never use a flammable spray such as hair spray, lacqueror

paint near the unit.

It may cause a fire.

CAUTION

Do not use the air conditioner for other purposes.

In order to avoid any quality deterioration, do not use the unit

for cooling precision instruments, food, plants, animals or

works of art.

Before cleaning, be sure to stop the operation, turn the

breaker off or pull out the supply cord.

Otherwise, an electric shock and injury may result.

In order to avoid electric shock or fire, make sure that an

earth leak detector is installed.

Be sure the air conditioner is grounded.

In order to avoid electric shock, make sure that the unit is

grounded and that the earth wire is not connected to gas or

water pipe, lightning conductor or telephone earth wire.

In order to avoid injury, do not remove the fan guard of the

outdoor unit.

Do not operate the air conditioner with a wet hand.

An electric shock may happen.

Do not touch the heat exchanger fins.

These fins are sharp and could result in cutting injuries.

Never inspect or service the unit by yourself.

Ask a qualified service person to perform this work.

Do not dispose this product as unsorted municipal

waste.Collection of such waste separately for special treatment

is necessary.

Keep far away from high-frequency equipment.

Keep away from the following places:

a place where it is full of oil gas; places where salty air

surrounding(near the coast); a place where is caustic gas(the

sulfide in hotspring). Location in the folling places may cause

malfunction or shorten the life span of the manchine.

In the cace of extremely strong wind, please prevent the air

from flowing backwards into the outdoor unit.

Snow canopy is necessary in sonwfall places on the outdoor

unit. Please consult the local dealer for details.

In the frequent thunderstruck place, lightning proof actions

should be taken.

To prevent refrigerant leak, contact your dealer.

When the system is installed and runs in a small room, it is

required to keep the concentration of the refrigerant, if by any

chance coming out, below the limit. Otherwise, oxygen in the

room may be affected, resulting in a serious accident.

The refrigerant in the air conditioner is safe and normally does

not leak.

Do not operate the air conditioner when using a room

fumigation - type insecticide.

Failure to observe could cause the chemicals to become

deposited in the unit, which could endanger the health of

those who are hypersensitive to chemicals.

Do not place appliances which produce open fire in places

exposed to the air flow from the unit or under the indoor unit.

It may cause incomplete combuston or deformation of the

unit due to the heat.

Do not install the air conditioner at any place where

flammable gas may leak out.

If the gas leaks out and stays around the air conditioner, a

fire may break out.

The appliance is not intended for use by young children or

infirm persons withoutsupervision.

Young children should be supervised to ensure that they do

not play with the appliance.

Fig. 2-1 Lifting of the unit

Handling of the unit

The angle of inclination should not be more than 15º when carrying the unit, to avoid overturn of the unit.

a. Rolling handling: several rolling rods of the same size are placed under the base of the unit, and the length of each rod must be more

than the outer frame of the base and suitable for balancing of the unit.

b. Lifting: the strength lifting rope (belt) can bear should be 4 times the weight of the unit. Check the lifting hook and ensure that it is firmly

attached to the unit, and the lifting angle should be more than 60º. To avoid damages to the unit, the contact position of the unit and lifting

rope should be provided with an at least 50mm thick wood block, cloth or hard paper. Any person is not allowed to stand below the unit

when lifting it.

3.3 Requirements of arrangement space of the unit

3.3.1 Requirements of arrangement space of the unit

3.3.1.1 To ensure adequate airflow entering the condenser,

the influence of descending airflow caused by the high-rise

buildings around upon the unit should be taken into account

when installing the unit.

3.3.1.2 If the unit is installed where the flowing speed of air is

high, such as on the exposed roof, the measures including

sunk fence and Persian blinds can be taken, to prevent the

turbulent flow from disturbing the air entering the unit. If the

unit needs to be provided with sunk fence, the height of the

latter should not be more than that of the former; if Persian

blinds are required, the total loss of static pressure should be

less than the static pressure outside the fan. The space

between the unit and sunk fence or Persian blinds should also

meet the requirement of the minimum installation space of the

unit.

3.3.1.3 If the unit needs to operate in winter, and the

installation site may be covered by snow, the unit should be

located higher than the snow surface, to ensure that air flows

through the coils smoothly.

3.4 Space requirements for parallel installation of

multiple modular units

To avoid back flow of the air in the condenser and operational

faults of the unit, the parallel installation of multiple modular

units can follow the direction A and D as shown in Fig. 3-2, the

spaces between the unit and the obstacle are given in Table

3.1, and the space between adjacent modular units should not

be less than 300mm; the installation can also follow the

direction B and C as shown in Fig. 3-2, the spaces between the

unit and the obstacle are given in Table 3-1, and the space

between adjacent modular units should not be less than

600mm; the installation can also follow the direction

combination of A and D, and B and C, the spaces between the

unit and the obstacle are given in Table 3-1, the space

between adjacent modular units in the direction A and D should

not be less than 300mm, and the space between adjacent

modular units in the direction B and C should not be less than

600mm. If the spaces mentioned above cannot be met, the air

passing from the unit to the coils may be restricted, or back

flow of air discharge may occur, and the performance of the

unit may be affected, or the unit may fail to operate.

3.5 Installation foundation

a. The unit should be located on the horizontal foundation, the

ground floor or the roof which can bear operating weight of the

unit and the weight of maintenance personnel. Refer to Table

9.1 (Table of applicable models and parameters) for operating

weight.

b. If the unit is located so high that it is inconvenient for

maintenance personnel to conduct maintenance, the suitable

scaffold can be provided around the unit.

c. The scaffold must be able to bear the weight of maintenance

personnel and maintenance facilities.

d. The bottom frame of the unit is not allowed to be embedded

into the concrete of installation foundation.

installation & owner’s manual

3.6 Installation of damping devices

3.6.1 Damping devices must be provided between the unit

and its foundation.

By means of the Φ15mm diameter installation holes on the

steel frame of the unit base, the unit can be fastened on

the foundation through the spring damper. See

Fig.3-3(Schematic diagram of installation dimension of the

unit) for details about center distance of the installation

holes. The damper does not go with the unit, and the user

can select the damper according to the relevant

requirements. When the unit is installed on the high roof or

the area sensitive to vibration, please consult the relevant

persons before selecting the damper.

3.6.2 Installation steps of the damper

Step 1. Make sure that the flatness of the concrete

foundation is within ±3mm, and then place the unit on the

cushion block.

Step 2. Raise the unit to the height suitable for installation

of the damping device.

c. Remove the clamp nuts of the damper.

Step 3. Place the unit on the damper, and align the fixing

bolt holes of the damper with the fixing holes on the unit

base.

Step 4. Return the clamp nuts of the damper to the fixing

holes on the unit base, and tighten them into the damper.

Step 5. Adjust the operational height of the damper base,

and screw down the leveling bolts. Tighten the bolts by

one circle to ensure equal height adjustment variance of

the damper.

Step 6. The lock bolts can be tightened after the correct

operational height is reached.

Anchor bolt M12

Nut

Ferrol

It is recommended that the damper should be fastened on

the foundation with the provided holes. After the unit is

placed on the foundation, the damper connected with the

unit should not be moved, and the central clamp nut is not

allowed to be tightened before the damper sustains load.

Fig. 3-5

4. WATER SYSTEM INSTALLATION

4.1 Basic requirements of connection of chilled

water pipes

● After the unit is in place, chilled water pipes can be laid.

● The relevant installation regulations should be abided with

when conducting connection of water pipes.

● The pipelines should be free of any impurity, and all chilled

water pipes must conform to local rules and regulations of

pipeline engineering.

● Connection requirements of chilled water pipes

a. All chilled water pipelines should be thoroughly flushed, to be

free of any impurity, before the unit is operated. Any impurity

should not be flushed to or into the heat exchanger.

b. Water must enter the heat exchanger through the inlet;

otherwise the performance of the unit will decline.

c. The inlet pipe of the evaporator must be provided with a

target flow controller, to realize flow-break protection for the

unit. Both ends of the target flow controller must be supplied

with horizontal straight pipe sections whose diameter is 5 times

that of the inlet pipe. The target flow controller must be installed

in strict accordance with “Installation & Regulation Guide for

Target Flow Controller” (Figure 4.3~4.4). The wires of the target

flow controller should be led to the electric cabinet through

shielded cable (see Electric Controlling Schematic Diagram for

details). The working pressure of the target flow controller is

1.0MPa, and its interface is 1 inch in diameter. After the

pipelines are installed, the target flow controller will be set

properly according to the rated water flow of the unit.

d. The pump installed in the water pipeline system should be

equipped with starter. The pump will directly press water into

the heat exchanger of the water system.

e. The pipes and their ports must be independently supported

but should not be supported on the unit.

f. The pipes and their ports of the heat exchanger should be

easy to disassemble for operation and cleaning, as well as

inspection of port pipes of the evaporator.

g. The evaporator should be provided with a filter with more

than 40 meshes per inch at site. The filter should be installed

near to the inlet port as much as possible, and be under heat

preservation.

h. The by-pass pipes and by-pass valves as shown in Fig. 4-1

must be mounted for the heat exchanger, to facilitate cleaning

of the outside system of water passage before the unit is

adjusted. During maintenance, the water passage of the heat

exchanger can be cut off without disturbing other heat

exchangers.

i. The flexible ports should be adopted between the interface of

the heat exchanger and on-site pipeline, to reduce transfer of

vibration to the building.

j. To facilitate maintenance, the inlet and outlet pipes should be

provided with thermometer or manometer. The unit is not

equipped with pressure and temperature instruments, so they

need to be purchased by the user.

k. All low positions of the water system should be provided with

drainage ports, to drain water in the evaporator and the system

completely; and all high positions should be supplied with

discharge valves, to facilitate expelling air from the pipeline. The

discharge valves and drainage ports should not be under heat

preservation, to facilitate maintenance.

installation & owner’s manual

l. All possible water pipes in the system to be chilled should be

under heat preservation, including inlet pipes and flanges of the

heat exchanger.

m. The outdoor chilled water pipelines should be wrapped with

an auxiliary heating belt for heat preservation, and the material

of the auxiliary heat belt should be PE, EDPM, etc., with

thickness of 20mm, to prevent the pipelines from freezing and

thus cracking under low temperature. The power supply of the

heating belt should be equipped with an independent fuse.

n. When the ambient temperature is lower than 2°C, and the

unit will be not used for a long time, water inside the unit should

be drained. If the unit is not drained in winter, its power supply

should not be cut off, and the fan coils in the water system must

be provided with three-way valves, to ensure smooth circulation

of the water system when the anti-freezing pump is started up in

winter.

o. The common outlet pipelines of combined units should be

provided with mixing water temperature sensor.

WARNING

● For the water pipeline network including filters and heat

exchangers, dreg or dirt may seriously damages the heat

exchangers and water pipes.

● The installation persons or the users must ensure the

quality of chilled water, and de-icing salt mixtures and air

should be excluded from the water system, since they may

oxidize and corrode steel parts inside the heat exchanger.

4.8 Water quality control

4.8.1 Water quality control

When industrial water is used as chilled water, little furring may

occur; however, well water or river water, used as chilled water,

may cause much sediment, such as furring, sand, and so on.

Therefore, well water or river water must be filtered and softened

in softening water equipment before flowing into chilled water

system. If sand and clay settle in the evaporator, circulation of

chilled water may be blocked, and thus leading to freezing

accidents; if hardness of chilled water is too high, furring may

occur easily, and the devices may be corroded. Therefore, the

quality of chilled water should be analyzed before being used,

such as PH value, conductivity, concentration of chloride ion,

concentration of sulfide ion, and so on.

4.9 Installation & regulation guide for target flow

controller

Please carefully check flow switches before conducting

installation of the target flow controller. Packing should be in

good condition, and the appearance should be free of

damage and deformation. If any problem, please contact the

manufacturer.

Flow switches can be installed in the horizontal pipeline or

the vertical pipeline with upward flowing direction but cannot

be mounted in the pipeline with downward flowing direction.

The inlet water of gravity should be taken into account when

flow switches are installed in the pipeline with upward flowing

direction.

Target flow controller must be installed on a section of

straight-line pipeline, and its both ends must be supplied with

straight-line pipes whose length is at least 5 times diameter

of the pipe. In the meanwhile, the fluid flowing direction in the

pipeline must be consistent with the direction of arrow on the

controller. The connection terminal should be located where

wiring connectioncan be easily done.

Pay attention to the following items when conducting

installation and wire connection:

4.9.1

4.9.2

4.9.3

4.9.4

Collision of the wrench with the soleplate of the flow switch

is prohibited, since such collision may cause deformation

and failure of the flow switch.

To avoid electric shock and damages to the devices, the

power supply should be cut off, when wires are connected

or adjustment is done.

When wiring connection is conducted, adjustment of other

screws except connection terminals of micro switches and

ground screws is prohibited. In the meanwhile, over great

force should not applied when wires of micro switches are

connected, otherwise micro switches may suffer

displacement, thus leading to failure of flow switches.

Special grounding screws should be used for earth

connection. Bolts should not be installed or removed at

will; otherwise flow switches may suffer deformation and

failure.

Flow switches have been set at minimal flow value prior to

ex-factory. They should not be adjusted below the

ex-factory setting value, or they may suffer failure. After

installing flow switches, please press the flow switch lever

several times to check them. When the lever is found not

to respond with “clatter”, rotate the screw in a clockwise

direction, until “clatter” occurs.

4.7 Selection and installation of the pump

4.7.1 Select the pump

a. Select the water-flow of the pump

The rated water-flow must no less than the unit rated water-flow;

in terms of multi-connect the units, that water-flow must no less

than total units’ rated water-flow.

b. Select the left of the pump.

H=h1+h2+h3+h4

H: The lift of the pump.

h1: Main unit water resistance.

h2: Pump water resistance.

h3: Water resistance of the longest water-loop distance, includes:

pipe resistance, different valve’s resistance, flexible pipe

resistance, pipe elbow and three-way resistance, two-way

resistance or three-way resistance, as well as filter resistance.

H4: the longest terminal resistance.

4.7.2 Installation the pump

a. The pump should be installed at the water inlet pipe, both of

which sides must mount the soft connectors for vibration-proof.

b. The backup pump for the system (recommended).

c. Units must with a main unit controls (Please see Fig. 5-3 for the

controls wiring diagram).

installation & owner’s manual

Determine whether the flow switch and the system

connected with it are in good operation according to the

measured value by flow meter, namely, when the measured

value on flow meter is less than 60% of rated water flow of

the unit, the target flow controller should be cut off and

observed for 3 working periods, and it should be covered

with flow switch shell timely.

4.10 Installation of single-module water system

pipeline

Be sure to determine the model of target slice according to

the rated flow of the unit, the diameter of the outlet pipe

and the adjustment range of the target slice of the flow

switch. Besides, the target slice should not contact with

other restrictors in the pipeline or on the inner wall of the

pipeline, or the flow switch cannot be reset normally.

5.6 Detail description for parts in fig. 5-5

Detection of current of the compressor B (protection code P5)

T4: outdoor ambient temperature sensor (fault code E7)

T3B: pipe temperature sensor of the condenser B (fault code E6 and protection code P7)

T3A: pipe temperature sensor of the condenser A (fault code E5 and protection code P6)

1) T4: if there is one system that requires starting outdoor fans, the fans are started through electric control of the

unit. Outdoor fans set high wind, low wind two respectively, and control the unit through T4.

2) T3B and T3A: when the electric control of the modular unit detects the temperature of the outdoor pipe T3A or

T3B of the system exceeds the protective temperature 65ć, the corresponding system will be shut down. And it

will be re-started up, after the temperature drops below the recovery temperature 60ć. Another system will be not

affected.

3) T4, T3B and T3A: when the temperature sensor is detected to suffer open circuit or short circuit, fault alarm will

occur.

● When the main unit suffer fault of temperature sensor: the main unit and subordinate units will be shut down.

● When the subordinate unit suffer fault of temperature sensor: the unit will be shut down, but other subordinate

units will not be affected.

Unit outlet water temperature sensor (fault code E4)

Under cooling mode and heating mode, conduct adjustment according to the magnitude of unit outlet water

temperature.

Total outlet water temperature sensor (fault code E3)

Only the main unit is valid, and the subordinate units are invalid.

Under refrigerating mode and heating mode, conduct adjustment according to the magnitude of total outlet

watertemperature. Adjustment range: shut-down, 40%, 60%, 80% and 100%.

No.

Table 5-2

Detection of current of the compressor A (protection code P4)

Current is not detected within the initial 5 seconds after the compressor is started up. When the current of

the compressor is detected to exceed protective value set (18A), it will be shut down and re-started after 3

min.

syetem A digital compressor exhaust temperature sensor(fault code E8, protection codeP8),Only the digital

modular is valid, and the constant speed modular are invalid.

Spot check. The operating status of outdoor system can be observed through spot check, and specific display

contents are as shown in the following figure:

Normal display

Operating mode Operating capability of the compressor B Number of online units Outdoor ambient temp. Temp. of the condenser A

Plate heat exchanger’s frost-proof temp Unit outlet water temp Unit inlet-water tempe Temp. of the condenser B

● Display contents of “operating mode”: 1. cooling; 2. heating; 4. pump; 8. Stand-by

● Display contents of “number of online units”: the main unit can display the number of online units, and the

subordinate unit displays 0.

When the address

is 1,2,3……F, it

serves as the

subordinate unit

1,2,3……15.

When the

address is 0, it

serves as the

main unit.

Each modular part of modular unit has the same

electric control function, and the main unit and

subordinate units can be set through address code

on the electric control board. The address code 0 #

is provided as the main unit. The priority of being

the main unit is given to the unit with digital

compressor, and other addresses are subordinate

units. Only the unit is chosen as the main unit, its

electric control can activate such functions as

direct communication with the wired controller,

refrigerating and heating capability adjustment,

pump control, auxiliary electric heater control, total

effluent temperature detection and water flow

switch detection.

COM (O) 485 communication port (fault code E2)

high-pressure protection of the system A and discharge temperature switch protection (protection code P0);

high-pressure protection of the system B and discharge temperature switch protection (protection code P2);

low-pressure protection of the system A (protection code P1);

low-pressure protection of the system B (protection code P3);

1) Constant speed compressor: connection of discharge temperature switch and high-pressure switch of

the system in series.

2)Digital compressor: With dual-protection from Air Exhaust Temp. Switch and Air Exhaust Temp. Sensor.

The Switch tandem connects with the Hi-pressure switch in the system, while the Sensor enjoys an

exclusive connector.

The Air Exhaust Temp. Sensor at Digital Compressor: Air exhaust temperature value (DLT) protects the

compressor (Fixed frequency compressor doesn’t inspect this port). When DLT work in normal (no air

exhaust temp. sensor error, if does, will display the error code E8), three temperature areas protections will

be conducted: Safety Area, Yellow Area and Red Area. In case of DLT temperature lower than 125?, there

is no protection will perform; in case of DLT higher than 125?, after 10 minutes continual operation, it will

enter to Yellow Area, the capacity output from the digital compressor will decrease to 40%, once the

temperature reduce to 100?, it will go back to the Safety Area, and compressor stop down, error be

released, system will restart after 3 minutes later.v

Water inlet temp sensorT62 (TBH2) (faulti code EF)

Frost-proof sensorT61 (TBH1) (fault code Eb)

Water flow detection (fault code of the main unit E0) is only valid for the main unit but invalid for

subordinate units.

1) Main unit: if abnormal water flow occurs for the first and second time, the main unit board will display

fault code E9. If abnormal water flow occurs the third time, the main unit board will display fault code E0

(off-power recovery is needed), and the wired controller will display fault code E0 (fault is displayed only

after 3 detection).

2) Subordinate unit: (Joint this terminal with short-connective wiresˈwater flow detection will not be

done).

6. TRIAL RUN

6.1 Points for attention prior to trial run

After the water system pipeline is flushed several times, please make sure that the purity of water meets the requirements; the

system is re-filled with water and drained, and the pump is started up, then make sure that water flow and the pressure at the outlet

meet the requirements.

The unit is connected to the main power 12 hours before being started up, to supply power to the heating belt and pre-heat the

compressor. Inadequate pre-heating may cause damages to the compressor.

Setting of the wired controller. See details of the manual concerning setting contents of the controller, including such basic settings as

refrigerating and heating mode, manual adjustment and automatic adjustment mode and pump mode. Under normal circumstances,

the parameters are set around standard operating conditions for trial run, and extreme working conditions should be prevented as

much as possible.

Carefully adjust the target flow controller on the water system or the inlet stop valve of the unit, to make the water flow of the system

be 90% of the water flow specified in Table 7-1.

CAUTION

6.3 Trial run

6.3.1 Start up the controller and check whether the unit displays a

fault code. If a fault occurs, remove the fault first, and start the

unit according to the operating method in the “unit control

instruction”, after determining that there is no fault existing in

the unit.

6.3.2 Conduct trial run for 30 min. When the influent and effluent

temperature becomes stabilized, adjust the water flow to

nominal value, to ensure normal operation of the unit.

6.3.3 After the unit is shut down, it should be put into operation 10

min later, to avoid frequent start-up of the unit. In the end,

check whether the unit meets the requirements according to

the contents in Table 9.1.

● The target flow controller must be installed correctly. The

wires of the target flow controller must be connected according

to electric control schematic diagram, or the faults caused by

water breaking while the unit is in operation should be the

user’s responsibility.

● Do not re-start the unit within 10 min after the unit is shut

down during trial run.

● When the unit is used frequently, do not cut off the power

supply after the unit is shut down; otherwise the compressor

cannot be heated, thus leading to its damages.

● If the unit is not in service for a long time, and the power

supply needs to be cut off, the unit should be connected to the

power supply 12 hours prior to re-starting of the unit, to

pre-heat the compressor.

7. USE

● The unit can control start-up and shut-down of the unit, so

when the water system is flushed, the operation of the pump

should not be controlled by the unit.

● Do not start up the unit before draining the water system

completely.
