The
2.2 Principle of Operation
The heat generated by the sun, wind and rain is stored in the ground. This heat stored in the ground is collected at low temperature by the brine circulating in the ground collector, ground coil or similar device. A circulating pump then conveys the warmed brine to the evaporator of the heat pump. There, the heat is given off to the refrigerant in the refrigeration cycle. When so doing, the brine cools so that it can again take up heat energy in the brine circuit.
The refrigerant, however, is drawn in by the electrically driven compressor, is compressed and "pumped" to a higher temperature level. The electrical power needed to run the compressor is not lost in this process, but most of the generated heat is trans- ferred to the refrigerant as well.
Subsequently, the refrigerant is passed through the condenser where it transfers its heat energy to the heating water. Based on the thermostat setting, the heating water is thus heated to up to 55 °C.
BASELINE UNIT
The baseline unit consists of a heat pump of compact design, ready for connection. In addition to the control panel with integrated controller, the unit also contains essential components of the heating and brine circuits:
-expansion vessels
-circulating pumps
-pressure relief valves
-pressure gauges
-overflow valve (heating circuit)
The refrigeration cycle contains the refrigerant R407C. Refrigerant R407C is
All components required for the operation of the heat pump are provided on the control panel. The power feed for load and control current must be field- installed by the customer.
The collector loops including brine manifold must be provided by the customer.
