Abstract (en)
[origin: EP3967949A1] The purpose of the prevent invention is to appropriately prevent a refrigerant stagnation phenomenon from occurring, and to reduce the power consumption of heating control of the compressor.A heat source system includes an outdoor air temperature measuring device (150) which measures an outdoor air temperature, heaters which heat compressors used for refrigerating cycles, first memories (121) each of which stores a relationship between a temperature difference between an outdoor air temperature and a refrigerant saturation temperature at the time of saturation of a refrigerant and an intermittent operation period, and first controllers (120) each of which determines, at the time when each of the compressors is in a stopped state, an intermittent operation period on the basis of the outdoor air temperature and the relationship stored in each of the first memories (121), and executes heating control of each of the heaters according to the determined period.
