Abstract (en)
[origin: EP3163218A1] A heat pump type chiller (100) includes a compressor (10), a refrigerant-air heat exchanger (20), an expansion valve (40), and a refrigerant-circulating liquid heat exchanger (50) and cools a circulating liquid by heat exchange between the circulating liquid and a refrigerant. Temperature sensors (TWR, TWL, TWS) are provided respectively at a circulating liquid inlet port, at a circulating liquid outlet port, and on a surface portion of the refrigerant-circulating liquid heat exchanger (50). A pressure sensor (PL) is provided in a refrigerant suction path of the compressor (10). If it is detected that any one of temperatures detected by the three temperature sensors (TWR, TWL, TWS) and a refrigerant evaporation temperature calculated by converting a pressure detected by the pressure sensor (PL) is less than or equal to a predetermined temperature, the compressor (10) is stopped, and a circulation pump (300) for circulating the circulating liquid is activated.
