Abstract

Provided is a heat pump system (100) having a compressor (210), a liquid-side on-off valve (420), a gas-side on-off valve (460), and a controller (600). The controller is configured to perform a refrigerant recovery operation for recovering refrigerant from a utilization-side piping section (102) to a heatsource-side piping section (101) by operating the compressor while the liquid-side on-off valve is closed and the gas-side on-off valve is open, and control the system such that the gas-side on-off valve starts closing (S2100) when a predetermined valve-close condition is satisfied during the compressor is operating for recovering refrigerant, and such that the operation of the compressor for recovering refrigerant stops (S2400) after the closing of the gas-side on-off valve started.
