The invention provides a heat pump system which can presume the state of sucked refrigerant with high precision and protect a compressor while suppressing cost. The heat pump system is provided with: a refrigerant circuit (1) that includes a compressor (10) and circulates a refrigerant; a temperature sensor (2) that measures the temperature of the refrigerant; a pressure sensor (3) that measures the pressure of the refrigerant; and a drive suppression control device (4) that determines a decrease in the pressure of the refrigerant sucked into the compressor (10) on the basis of the measured value of the temperature sensor (2) and the measured value of the pressure sensor (3), and that suppresses the drive of the compressor (10), the drive suppression control device (4) suppressing the drive of the compressor (10) on the basis of the measured value of the temperature sensor (2) when a predetermined first condition is satisfied. When a predetermined first condition different from the first condition is satisfied, a decrease in pressure of the refrigerant sucked into the compressor (10) is determined and driving of the compressor (10) is controlled, and when a predetermined second condition different from the first condition is satisfied, a decrease in pressure of the refrigerant sucked into the compressor (10) is determined based on the measured value of the pressure sensor (3) and control of driving of the compressor (10) is suppressed.
