5. Propose of the heat pump
The heat pumps are currently the most suitable equipment to improve
efficiency in energy consumption. With this technology it is possible to
take from the environment the highest power, using only an electrical
power 3-5 times lower than the thermal energy transferred.
The thermal energy produced can be transferred to a central under floor
heating system, fan coil, low temperature radiators and DHW (domestic
hot water).
This equipment is very easy to install on the outside of your house,
ensuring all thermal comfort, even at low outdoor temperatures.
6. Heat pump features

ensure the low noise level with insulation.
•Good heat exchange rate
The heat pump unit use special designed heat exchanger to enhance
whole efficiency.
•Large working range
This series of heat pump is designed to work under different working
conditions as low as -15 degrees for heating.

ENERGIE Page | 9
7. Principle of operation
Ambient air is drawn in by the fan and passed over the evaporator. The
evaporator cools theair, i.e. it extracts the heat itcontains. In the evaporator,
the heatremoved is transferred to the working fluid (refrigerant).
With the aid of an electrically driven compressor, the absorbed heat is
"pumped" to a higher temperature level through an increase in pressure and
given off to the heating water via the condenser (heat exchanger).
In so doing, the electrical energy is used to raise the heat of the environment
to a higher temperature level.
Duetothefactthattheheatenergyextracted from the air istransferredtothe
heating water, this type of appliance is referred to as an air to water heat
pump.
The air to water heat pump consists of the following main components:
Evaporator, fan, expansion valve, low-noise scroll compressor, condenser
and the control unit.
Inthe case of lowambient temperatures, airhumiditymayaccumulateonthe
evaporator in the form of frost, impairing the heat transfer. The evaporator is
automatically defrosted by the heat pump, as required, with the possibility of
vapor plumes forming at the air outlet.
8. Device description
The running range of the heat pump:
Heating:
•Minimum ambient temperature -25oC to 35oC;
•Water temperature from 15oC to 60oC.
Cooling:
•Maximum ambient temperature 10oC to 43oC;
•Water temperature from 7oC to 25oC.
Compared with oil boiler, gas boiler and electrical heater, heat pump is
the best solution with high efficiency, safety and environment protect.
This high temperature air source heat pump use advanced heating
technology and intelligent control system. So it can work with the floor
heating pipe, the fan coil or the radiator, and replace the boiler directly.
In addition, the inverter heat pump can be used to provide hot water for
sanitary use, like kitchen, shower, etc.

The heat pump must be placed upon a level and firm base that is suitable to
carry the weight of the unit e.g. a 100mm concrete base. The base must
provide for the unit to be sitting at least 150mm above the surrounding
ground. Allow for a slight tilt of the unit (3mm across the width running from
right to left as you face the fan(s)) to allow rain water run-off and any water
enteringthe unit to drain through the holes in the bottom of the unit.
The unit must be secured to its base using suitable fixings through the unit
feet. The rubber feet supplied with the unit must be used. Alternatively, there
are proprietary unit fixings available that include an adjustable steel frame
and legs with rubber mounting pads.
The unit must befixed, stable and kept vertical during operation.
15.2 Condensate lines
Large amounts of condensation water, as well as melt water from defrosting
cycle can be produced. Provide good drainage at the installation area and
make sure water cannot run out onto paths or the like during periods that ice

ENERGIE Page | 16
can form. Ideally condensation water is led off to a drain or similar. The
condensation water pipe must have a minimum diameter of 50 mm and
should be discharged to the sewer drain in a frost-proof location
15.3 Water loop connection
Please pay attention to below matters when the water pipe is connected:
•Keep pipe work as free from bends as possible to keep back pressure in
the system to a minimum. Make sure that fittings, manifolds, water pumps
and valves in the system are designed for full flow as restrictions in the
system from these can materially and adversely impact upon the
performance of the unit and effectiveness of the overall heating system.
•The piping must be clear and free from dirty and blocks. Water leakage
test must be carried out to ensure there is no water leaking. And then the
insulation can be made.
•There must be expansion tank on the top point of the water loop, and the
water level in the tank must be at least 0.5 meter higher than the top point
of the water loop.
•The flow switch is installed inside of the heat pump, check to ensure that
the wiring and action of the switch is normal and controlled by the
controller.
•The connection between the heat pump and the construction is better to
be flexible type, to avoid vibration transfer. The support to the water pipe
must be separate, but not rely on the heat pump unit.
•There must be thermometer and pressure meter at the water inlet and
outlet, for easy inspection during running.
•There must be drainage on the low points of the water system, and there
is already drainage on the chassis of the heat pump. The water in the
system must be drain out during winter. if the heat pump is not running.
And there must be air vent on the high point of the water system to drive
air of the water. Drainage and air vent need not to be insulated, in order to
maintain.
ATTENTION
The hydraulic connection should be installed according to the local legal
laws and regulations as well as the qualified professional.

ENERGIE Page | 17
15.4 Water filter
Thefilterallowsblockanyimpuritiespresent inthehydraulic circuits. Residue
left in the heater pipes will damage the heat exchangers and cause the heat
pumps to malfunction. It is recommended install the filter in the heater return
line, especially if no buffer storage is present. It is indispensable in order to
prevent serious damageto the heat exchanger.
Note 1: The filter must contain a filtering mesh with holes that do not exceed
one millimeter.
Note 2; The filter should be kept cleaned and inspected periodically to
maintain your condition, cleanliness and ensuring the proper functioning of
Heat pump
15.5 Pressure drops (water filter)
15.6 Heating water quality
The composition and quality of the water in the system has a direct effect on
the performance of the entire system and the lifetime of the heat pump.
For the initial charging and backfill of the system, usually normal tap water
with apHvalue of7-8canbeusedaslongasthe waterisnothighlycorrosive
(chloride content > 150 mg/l) or hard (>14°dH; degree of hardness IV). A
drinking water analysis can be requested from the local water supply
company.
If the specific system volume is greater than 25 liters/kW heating output (e.g.
through the installation of a hot water buffer storage), then the maximum
permissible calcium carbonate input from the charging and backfilling water
should be calculated in accordance with the VDI guideline 2035. In some
cases the charging water has to be softened.
Note: The use of chemical anti-corrosion agents is not permitted.
