  • Patent number: 10724777
    Abstract: A controller in a refrigeration cycle apparatus performs a refrigerant recovery operation when switching an operation mode from a defrosting mode to a heating mode. During the refrigerant recovery operation, by rotating a fan of a blower while monitoring a pressure at a discharge side of the compressor, the controller is configured to perform feedback control to cause a high-pressure side pressure to be close to a high-pressure side target pressure value. During the refrigerant recovery operation, by controlling a driving frequency of the compressor while monitoring a pressure at a suction side of the compressor, the controller is configured to perform feedback control to cause a low-pressure side pressure to be close to a low-pressure side target pressure value.

  • Publication number: 20200064031
    Abstract: A chilling unit and a temperature control system using water circulation includes a refrigerant circuit, a pipe through which a heat medium flows, a flow switching device, a temperature sensor, a pressure sensor, and a controller. The refrigerant circuit includes a compressor, a pair of air-side heat exchangers, an expansion valve, and a heat-medium-side heat exchanger that are connected to each other by pipes, thereby enabling refrigerant to circulate in the refrigerant circuit. The flow switching device switches between refrigerant-circulation routes. The controller controls the compressor in accordance with a target outlet temperature, the temperature of the heat medium detected by the temperature sensor, and a pressure difference in the heat medium detected by the pressure sensor.
