ABSTRACT:
An outdoor unit has at least two variable-capability compressors and has an outdoor heat exchanger coupled to the compressors having lubricating oil supplying sections coupled together by an oil-balancing member. A plurality of indoor units are each coupled to the outdoor unit for forming a refrigerating cycle and each have at least an indoor heat exchanger and an output section for outputting demand capability data according to an air conditioning load of the indoor heat exchanger. In accordance with the demand capability data, a controller generates a parallel operation command for parallel operation involving both of the compressors of the outdoor unit with capability according to a sum of the demand capability data from the indoor units. The parallel operation command is executed by repeating a normal operation command for performing a normal operation over a given time and first and second oil-balancing operation commands for every given cycle, the first and second oil-balancing operation commands for effecting first and second oil-balancing operations having a mutually complimentary relation in preceding and succeeding stages of the normal operation.
