2Purpose of the Heat Pump

2.1Application

The air-to-water heat pump is designed for use in existing or newly built heating systems.

It is designed exclusively for heating and cooling heating water!

In heating operation, the heat pump is suitable for mono energy and bivalent operation down to an external temperature of - 20 °C.

Proper defrosting of the evaporator is guaranteed by maintaining a heating water return flow temperature of more than 18 °C dur- ing continuous operation.

The heat pump is not designed for the increased heat consump- tion required when a building is being dried out. The additional heat consumption should be met using special devices provided by the customer. If a building is to be dried out in autumn or win- ter, we recommend installing an additional heating element (available as an accessory).

In cooling operation the heat pump is suitable for temperatures ranging from +15 °C to +40 °C.

It can be used for silent and dynamic cooling. The minimum water temperature is +7 °C.

ATTENTION!

The device is not suitable for operation with a frequency converter.

2.2Operating Principle

Heating

Outside air is drawn in by the ventilator and fed via the evapora- tor (heat exchanger). The evaporator cools the air, i.e. it extracts heat from it. This extracted heat is then transferred to the working medium (refrigerant) in the evaporator.

The heat is “pumped” to a higher temperature level by increasing its pressure with the aid of an electrically driven compressor. It is then transferred to the heating water using the liquifier (heat ex- changer).

Electrical energy is used to raise the temperature of the heat in the environment to a higher level. Because the energy extracted from the air is transferred to the heating water, this type of device is called an air-to-water heat pump.

The air-to-water heat pump consists of the main components evaporator, ventilator and expansion valve, as well as the low- noise compressor, liquifier and electrical control system.

At low ambient temperatures, humidity accumulates on the evap- orator in the form of frost reducing the transfer of heat. The evap- orator is defrosted automatically by the heat pump as required. Steam may be emitted from the air outlet depending on the at- mospheric conditions.

3 Scope of Delivery

3.1Basic Device

The compact heat pump is supplied complete with all of the im- portant components of the heating circulation system:

„Expansion vessel

„Heat circulating pump

„Overflow valve and safety components (pressure relief valve, pressure gauge)

R404A is used as the refrigerant.

























1)Evaporator (heating operation)

2)Ventilator

3)24 l expansion vessel

4)Switch box

5)Liquifier (heating operation)

6)Compressor

7)Overflow valve

8)Heat circulating pump

9)Buffer tank

10)Filter dryer

11)Inspection window

12)Expansion valve

Cooling

The functions of the evaporator and the liquifier are reversed in the “Cooling” operating mode.

The heating water transfers its heat to the refrigerant via the liq- uifier which is now functioning as an evaporator. The compressor raises the temperature level of the refrigerant and the heat is passed on to the surrounding air via the liquifier (functioning as an evaporator in heating operation).
