摘要： An outdoor unit includes a pressure sensor for detecting an internal pressure of a first pipe. An outdoor unit controller is configured to: receive a switching signal; control an outdoor fan and a compressor to operate in a case where the switching signal instructs the outdoor unit to operate, the compressor operating at a first frequency; acquire a current state of the indoor fan in a case where the on signal instructs the outdoor unit to shut down; and control the compressor and the outdoor fan to operate if the current state of the indoor fan is an operating state, the compressor operating at a second frequency. The second frequency is lower than the first frequency. The current state of the indoor fan is obtained according to the internal pressure of the first pipe.

摘要： An air-conditioning apparatus includes a refrigerant circuit, an air-conditioning load state detection unit, an operation-state detection unit, and a controller. The refrigerant circuit includes a main circuit and a bypass circuit. The air-conditioning apparatus has a simultaneous heating and defrosting operation mode. In the simultaneous heating and defrosting operation mode, the controller controls a compressor, a pressure reducing device, and a defrosting refrigerant pressure-reducing device such that control amounts of the compressor, the pressure reducing device, and the defrosting refrigerant pressure-reducing device reach respective normal-time control target values that are set based on an air-conditioning load state and an operation state.

摘要： A refrigeration cycle device includes a heat source, a first use unit, a second use unit, a first connection flow path, and a second connection flow path. The heat source has a compressor and a heat-source side heat exchanger. The first use unit is separated from the heat source unit and has a first use-side heat exchanger. The second use unit is separated from the heat source unit and has a second use-side heat exchanger. The first connection flow path connects the heat source unit to the first and the second use units and causes a first refrigerant to flow. The second connection flow path connects the heat source unit to the first and the second use units and causes a second refrigerant to flow. A specific enthalpy of the second refrigerant is smaller than a specific enthalpy of the first refrigerant.
