PROBLEM TO BE SOLVED: To provide a heat pump device configured to switch the number of devices in operation by the optimal total frequency of compressors corresponding to a pressure condition.SOLUTION: A heat pump device 100 decides the optimal number of devices in the operation of refrigeration equipment 10 so that the COP of the entire system becomes the largest based on the operation capacity of the refrigeration equipment 10 which is currently operated, the discharge pressure of a compressor 1 of the refrigeration equipment 10 which is currently operated, a suction pressure of the compressor 1 of the refrigeration equipment 10 which is currently operated, and switches to the decided number of devices in operation. |
