DUCTING AND NOISE LEVEL REDUCTIONDUCTING AND NOISE LEVEL REDUCTION

DUCTING AND NOISE LEVEL REDUCTION

Water circuit heat pumps are usually installed in conjunction with an air blowing duct. A return air duct may also be

required. All ductwork shall be compliant with best air conditioning engineering practices.

The air blowing duct system normally consists of a flexible connector mounted on the unit, a bridging section to link to

the size of the main duct, a short section of straight duct, an elbow without a damper and a main duct with spurs

equipped with distribution grilles as illustrated in the drawing below. The sum total of the bridging section angles must

not be higher than 30°, otherwise there will be significant performance losses.

Do not connect the main duct directly to the unit without a bridging section to reduce the duct size to that of the unit’s

connection collar. In the event of using metal ducts, only the sides of the elbow section and all the spur duct sections

should be covered with fibreglass sound insulation for reducing the noise level. Fibreglass duct panels are more sound

absorbent and may enable the flexible canvas connection to be eliminated.

The duct network must be laid out to avoid any rectilinear runs betweens the heat pump outlet and the air distribution

outlets.

The return air intake ducts can be connected to a grille/filter located at the base of a wall, then directed via hollow

partitions towards a ceiling mounted plenum or via ceiling mounted grilles. The ceiling grilles must not be located

directly below the air conditioning unit.

The return air intake duct can be connected directly to the standard filter bracket. (Lateral filter removal advisable).

Do not drill panel screws directly into the unit’s casing for connecting the blowing and return air intake ducts, especially

on the air return side, as there is a risk of damaging the condensate recovery tray and the battery.

to modify the air-blowing configuration on site. To achieve this:

1 - Remove the top panel 11

2 - Remove the fan motor access panel 22

2 and release a small length of

motor cable.

3 - Remove the fan blower panel 33

4- Fit the fan blower panel 33

VENTILAVENTILA

An outdoor air intake (new air) may be required for ventilation. The blown air temperature must be controlled in order

to avoid the temperature of the mixture of outdoor air and return air at the heat pump inlet exceeding the appliance’s

operating limits. It is also common practice to shut down ventilation during periods of inoccupation (night time setting

of the set temperature).

Each appliance’s ventilation system is generally a sub-system within the building, with its own distribution duct network.

The simple introduction of outdoor air into each return air plenum, quite close to the unit’s return air intake is sufficient

and recommended. New air should not be introduced directly into the appliance. Provide for a sufficient distance to

ensure effective mixing of the outdoor air with the return air. (Refer to "Operating limits").

1. It is recommended that all units are connected to a water supply and return pipe system of the Tickelman Loop

type. The Tickelman Loop system is self-balancing and thus only requires manual balancing if a large number

of units with different flow and pressure loss characteristics are connected to a single hydraulic loop. A very

simple way of checking the hydraulic balance is to measure the temperature difference between the water

connections. To ensure a correct water flow, the difference must be in the region of 3 to 7 °C in Cooling mode

and 2 to 5°C in Heating mode.

A system with two parallel pipes can also operate in a perfectly adequate manner, but it is more difficult to

achieve, and to maintain, balance.

2. Steel, copper or P.V.C. pressure pipes may be used.

3. It is advisable to make the unit’s water supply and return conveyance lines with short lengths of high-pressure

hose, as they form excellent shock absorbers for unit operating noise and hydraulic pressure surges.

One of the hose ends must be fitted with a rotating connector to facilitate removal for maintenance. Rigid pipes

can be connected directly to the unit, but this is not recommended due to their inability to absorb vibrations and

noise.

Rigid pipes must be equipped with removable connectors to facilitate future removal of the unit from its location.

4. Certain flexible hose threaded connectors are supplied with sealing paste. If this is not the case, use Teflon tape

to create a tight seal.

5. Each unit must be equipped with isolation valves on the water inlet and outlet pipes. The return isolation valve

is used for both cutting off the water supply and balancing the installation’s water flow. As it is used to establish

the balance of the flows, it must be equipped with a lockable position end stopmust be equipped with a lockable position end stop

must be equipped with a lockable position end stopmust be equipped with a lockable position end stop

must be equipped with a lockable position end stop. This end stop ensures

that, after the valve is closed, it can only be re-opened as far as the position required to maintain a balanced

water flow.

these operations, the units must be connected, with all valves completely open, ready for

the system to be filled with water.

COMMENTCOMMENT

COMMENT::

: In order to limit clogging the plate heat exchanger and to optimise unit operation, it is advisable to

equip the system with a sieve filtersieve filter

sieve filtersieve filter

sieve filter (Ø 0.8 mm) on the unit water inlet pipe work. This filter should be installed between

two isolation valves and should remain accessible to the user for periodic checks.

7. Use steel, copper or P.V.C. pipes for the condensates drainage pipe. Each unit is supplied with a connector for

condensates drainage.

8. The condensates drainage line must comprise a siphon and run from the unit on a downward slope of at least

Generally, the siphon is connected directly to the unit’s condensates drainage outlet. A length of plastic pipe

can be used between the siphon and the condensates drainage line.

A complete condensates drainage system with copper or P.V.C. pipe can also be used.

Screw-on connectors shall be fitted to facilitate drainage pipe removal if copper pipe is used for the drainage

pipe work.

9. No point of the condensates drainage pipe work should be located above the level of one of the units’

condensate drainage outlet connection.

10. The circuits’ high points must be bled of air.

11. Comply with current regulations in terms of dielectric isolation of the connectors and the pipe work.

USHING OUT THE SYSTEM

1. Before commissioning an appliance for the first time, the water loop must be cleaned and rinsed out to remove

any dirt and manufacturing debris.

If the appliances are equipped with isolation valves (either

electric or pressostatic), the water supply and return

conveyance circuits to and from each machine must be

connected to each other. This will avoid any dirt being

introduced into the units.

Flushing water through the units is acceptable if they are not

equipped with water flow control devices.

2. The system must be filled from the mains water supply. All air

bleeds must be open during filling. Close the air bleeds once

the system is filled.

The installer must start the main circulation pump with the

water top-up tap on the pressure reduction valve in the open

position. Check the air bleeds by increasing order of height

to ensure water flows freely throughout the entire system.

Power supply to the cooling tower must be shut down, and

the water loop temperature regulation thermostat must be set

at 27 °C.

As the water circulates through the system, the installer must seek out and repair any possible pipe work leaks.

The drain cocks, on the lowest points on the circuit, must be open for flushing out and chasing out any

impurities. Ensure that the mains water valves are adjusted to allow water to enter at the same speed as it exits.

Check the pump inlet pressure gauge and manually adjust the compensating valve to maintain the same

pressure before and after the opening of the drain taps. Flushing must be performed for at least two hours, or

longer if necessary, until clear and clean water is obtained at the drain taps.

3. Stop the additional heating and the water circulation pump. Open all the bleed points and the drain taps to

empty the system completely. The short-circuited water supplies and returns must now be connected to the units’

inlet and outlet connections. It is recommended to use Teflon tape on the pipe connector threads. Do not use

sealing paste on the hoses’ rotating connecters.

Therefore, it is now recommended that the system is flushed out with hot water (30 °C).

5. Fill the system again with clean water. Test the water acidity level (litmus paper), and treat as required to obtain

a slightly alkaline water quality (pH 7.5 to 8.5).

At this stage, the recommended percentage of anti-freeze can be added. Use commercial quality anti-freeze

specifically intended for air conditioning systems. Do not use automobile radiator anti-freeze.

6. On the main electrical cabinet, adjust the heater set temperature point at 20 °C and the cooling tower set

temperature at 30 °C. Connect the power supply to all motors and start the circulation pumps.

When the normal flow level has been reached through all components, including the cooler (irrespective of the

season) and when the air is bled form the system and the loop temperature has stabilised, each appliance is

ready to be checked, tested and started for balancing the air and water flows.
