Abstract: A condenser includes a condensation section, a super-cooling section located above the condensation section, and a liquid receiver. The liquid receiver has a first space communicating with the condensation section through a refrigerant inlet and a second space located above the first space and communicating with the super-cooling section through a refrigerant outlet. A suction pipe which is open at upper and lower ends thereof and which establishes communication between the first space and the second space is disposed in the first space. A tubular flow control member whose upper end is open is disposed around the suction pipe such that the refrigerant having flowed into the first space through the refrigerant inlet hits against the flow control member and changes its flow direction. Since the refrigerant inlet is located within the vertical range of the flow control member, the refrigerant hits against the flow control member.

Abstract: An air conditioner 1 of the embodiment of the present invention, when all compressors 21a-21c have been stopping for a given time or more, starts an air conditioning operation without performing pressure equalizing control in switch units 6a-6d with starting the operation of the air conditioner 1.

Abstract: A rotational speed Cr of a compressor 21 during a defrosting operation is controlled within a control range that corresponds to a capacity ratio P, a total sum Pi of rated capacity of an indoor unit, or a refrigerant pipe length Lr. Accordingly, even in the case where a refrigerant circulation amount during the defrosting operation is reduced due to an installation state of an air conditioner 1, it is possible to prevent suction pressure from being significantly reduced and falling below a performance lower limit value of the compressor 21. Thus, damage to the compressor 21 can be prevented. In addition, it is possible to prevent a case where the suction pressure falls below the performance lower limit value of the compressor 21 and thus low-pressure protection control is executed. Therefore, a case where the restoration of the heating operation is delayed does not occur.
