摘要： A refrigeration cycle has a compressor, an outdoor rotary-type heat exchanger, a motor-operated expansion valve, and an indoor rotary-type heat exchanger which are sequentially connected to each other to circulate a refrigerant. A tank is set in a connected state or a non-connected state with respect to a refrigerant discharge side of the compressor. A detector detects at least a pressure at one side of each of the exchangers. A first controller sets the tank in a non-connected state when a normal operation of an air conditioner is to be started, and controls the capacity of the compressor, the rotational speed of the exchangers, and the opening degree of the valve in accordance with an air-conditioning load, thereby performing the normal operation of the air conditioner. A second controller causes the compressor to keep operating at a predetermined capacity until a detection pressure from the detector coincides with a preset value, when the air conditioner is to be stopped, and sets the tank in a connected state while controlling the valve to a predetermined opening degree, thereby recovering a refrigerant in the tank. A third controller rotates the exchangers at a predetermined speed when the air conditioner is to be started, and sets the tank in a connected state while controlling the valve to a predetermined opening degree, thereby filling the refrigerant in the exchangers from the tank.

摘要： A regenerative refrigeration cycle apparatus includes a refrigeration cycle circuit which is constructed by connecting a compressor, a four-way valve, an indoor heat exchanger, an expansion valve, and an outdoor heat exchanger. A regenerative unit for accumulating heat is arranged between the discharge side of the compressor and the four-way valve, and first and second heat exchangers are arranged in the regenerative unit together with a regenerative material. In a regenerating operation mode of the refrigeration cycle circuit, part of the refrigerant discharged from the compressor flows through the first heat exchanger, the indoor heat exchanger, and the outdoor heat exchanger, while the remaining part of the refrigerant flows through the second heat exchanger and the outdoor heat exchanger. The refrigerant discharged from the compressor is condensed in both the first and second heat exchangers, thereby heating the regenerative material.

摘要： In a method of controlling start of a refrigerant-circulating compressor driven by a brushless motor in a refrigerating cycle, the brushless motor is started in accordance with an asynchronous forced commutation operation without use of rotor position detection signals; and when the rotor position detection signals can be detected a predetermined number of times or more due to synchronous commutations during the forced commutation operation, the asynchronous forced commutation operation is shifted to a synchronous commutation starting operation with the use of the rotor position detection signals.
