2.2Operating Principle
The heat generated by the sun, wind and rain is stored in the ground. This heat stored in the ground is collected at a low tem- perature by the brine circulating in the ground collector, ground coil or similar device. A circulating pump then conveys the “heated” brine to the evaporator of the heat pump. There the heat is given off to the refrigerant in the refrigerating cycle. This cools the brine so that it can once again absorb thermal energy in the brine circuit.
The refrigerant is drawn in by the electrically driven compressor, compressed and “pumped” to a higher temperature level. The electrical power needed to run the compressor is not lost in this process. Most of it is absorbed by the refrigerant.
Subsequently, the refrigerant is passed through the condenser where it transfers its heat energy to the heating water. Depend- ing on the set operating point (thermostat setting), the heating water is thus heated up to a max. of 60 °C.
3 Basic Device
The basic device consists of a
All components required for the operation of the heat pump are located on the control panel. An external wall temperature sensor including fixing accessories and a dirt trap are supplied with the heat pump. The power feed for the load current and the control current must be installed by the customer.
The supply lead of the brine circulating pump (to be provided by the customer) must be connected to the control panel. If re- quired, the supply lead of the brine pump is be equipped with a motor protection device.
The customer must provide both the collector and the brine cir- cuit manifold.
