2 PURPOSEPUMP OF HEAT 3

2.1 Field of Application

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

The heat pump is designed for the cooling or heating of water for heating purposes and the supply of domestic hot water!

The heat pump is suitable for mono-energetic and bivalent operation.

During heating mode, a heating water return temperature of more than 18 °C must be maintained in order to assure proper defrosting of the evaporator.

The heat pump is generally not designed for satisfying any increased heat demand during the drying phase of new buildings. The additional heat demand must therefore be met by special appliances to be supplied on site. For the structural drying of new buildings during autumn and winter, its is recommended that an additional electric heating element (available as an accessory) be installed.

CAUTION! The unit is not suited for operation with a frequency converter.

2.2 Principle of Operation

Ambient air is drawn in by the fan and passed over a finned heat exchanger, which extracts heat from the air in the heating mode or gives off heat to the air in the cooling mode. This energy difference is transferred to the working fluid (refrigerant) in the heat exchanger.

With the aid of an electrically driven compressor, the absorbed heat is "pumped" to a higher temperature level through pressure increase and - depending on the particular application (cooling or heating) - is given off to the heating water or the waste air via the heat exchanger.

During heating mode, electrical energy is used to raise the heat of the environment to a higher temperature level. Due to the fact that the energy extracted from the air is transferred to the heating water, this type of appliance is referred to as air-to- water heat pump.

The air-to-water heat pump consists of the following main components: evaporator, fan and expansion valve as well as the low-noise compressor, a condenser and the electric control unit.

In the case of low ambient temperatures in the heating mode, moisture contained in the air may accumulate on the evaporator in the form of frost thus impairing the heat transfer. The evaporator is automatically defrosted by the heat pump, if required. Vapour pluming may occur at the air outlet depending on the weather conditions.

3.1 Baseline Unit

The heat pump is deliverd as a compact unit containing the components listed below.

The refrigerant used is R407C.

3.2 Control Box

The control box is integrated in the heat pump. It is accessible after removal of the cover panel (the fastening screw holes of the cover panels are capped).

The control box houses the mains terminals, the power contactors, the soft start unit as well as the terminals for the remote control.

The control of the heat pump is effected via the remote control included in the scope of delivery (see also section 8.).
