Abstract (en)
A compression heat pump or compression cold energy machine has a coolant circuit which comprises an evaporator(1), a compressor (2), a condenser (3) and a controllable expansion valve (4). It is controlled by a control device (8) which is connected to a temperature sensor (9) located in the region between the compressor and the condenser and to a second sensor (10). The second sensor determines a value which represents a direct measurement for the condensation temperature in the condenser. The second sensor is a pressure sensor and is located in the high pressure region of the coolant circuit between the compressor and the expansion valve. The condenser of the compression heat pump is designed as a heat exchanger to transmit heat given up from the coolant to a heating medium of a heating circuit (7).
