WIPO Patent Application WO/2010/098071
Kind Code:
A1
Abstract:
Disclosed is a heat pump system (1) which is provided with: a heat source unit (2) having a variable-capacity compressor (21) and a heat source-side heat exchanger (24) which serves as a coolant evaporator; and a plurality of usage units (4a, 4b) which are connected to the heat source unit (2) and have usage-side heat exchangers (41a, 41b) which serve as coolant radiators. The operating capacity of the compressor (21) is controlled in such a way that the discharge pressure of the compressor (21) or an equivalent quantity of state reaches a first target value (A). The first target value (A) is determined on the basis of an equivalent target value (B) which is equivalent to the usage temperature required in the respective usage units.
