Title:
HEAT SOURCE SYSTEM AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2010/024178
Kind Code:
A1
Abstract:
Disclosed is a heat source system that can achieve energy savings. The heat source system is equipped with: a cold water primary control heat pump (1) that comprises a lower-stage evaporator (9) that cools cold water, and a lower-stage condenser (7) that exhausts heat into the cooled water and outputs the cold water that has been cooled by the lower-stage evaporator (9) to an external load, and a hot water primary control heat pump (51) that comprises a higher-stage evaporator (59), which is supplied with heat from medium-temperature water that has been heated by the exhaust heat from the lower-stage condenser (7), and a higher-stage condenser (57) that heats high-temperature water and outputs to an external load the high-temperature water that has been heated by the higher-stage condenser (57); in addition, the lower limit temperature for the cooling water is set based on the temperature setting for the high-temperature water.
