3 Description of the appliance
Function
The heat pump converts low temperature heat
(e.g. heat from the outside air) into heat of higher
temperatures (heating water).
The heat pump extracts from ambient
- ground
-
ground water
-
air
the stored solar energy and returns this, plus
drive energy (electricity for the compressor) in
the form of heat to the heating and hot water
circuits.
The system consists of separate circuits, which
are coupled by means of a heat exchanger.

The refrigerant circuit consists of:
-
finned heat exchanger as evaporator
-
compressor, mounted on a noise and vibra-
tion dampening thick metal plate
-
plate heat exchanger as condenser
- dryer, refrigerant sump, expansion valve, safe-
ty equipment
- Chlorine-free, non-inflammable safety refrig-
erant and biodegradable special oil for the
compressor.
Heat pump AIR 80 C13A and AIR 80
C22A
The heat pumps of the AIR 80 C13A (OLWP 65
plus) and AIR 80 C22A are split appliances,
whereby the machine unit is installed indoors and
the corresponding evaporator outdoors in the
free air.
The machine unit is suitable for indoor
installation only and is not suited for
outdoors.
The heat extraction (heat source system) normal-
ly takes place from the ambient air via a finned
tube evaporator. The AIR 80 C13A and AIR 80
C22A heat pumps operate at low temperatures in
bivalent-parallel operation. The heat pump can,
however, be combined at any time with a further
heat generator.
Construction
3.3.1 Compressor
The fully hermetic SCROLL compressors are spe-
cially designed for heat pump use, i.e. for the
highest loading. Various important constructive
measures protect the compressor, both under
normal operative conditions as well as overload-
ing. The compressors used by OCHSNER have the
highest performance and are the most durable.
The SCROLL compressors have only a few moving
parts and have no dynamic suction or pressure
valves. Furthermore, they are distinguished by a
very low vibration and noise level.
3.3.2 Housing
A profile frame, corrosion protected and with
elegant cladding plates. The complete cladding is
fitted with noise-dampening mats.
