摘要： A cooling and heating concurrent operation type of multiple refrigeration cycle comprises an indoor unit including a variable delivery type of compressor and an outdoor heat exchanger; indoor units including indoor heat exchangers, respectively; triple connection pipes of a high pressure gas pipe, a high pressure liquid pipe and a low pressure gas pipe, the triple connection pipes connecting between the outdoor unit and the indoor units; pressure detection means for detecting the intake pressure of the compressor and the discharge pressure of the compressor; and calculation and control means for comparing two detected values of the intake pressure and the discharge pressure of the compressor with two set values of a set intake pressure and a set discharge pressure, and for making variable controls of the compression capability of the compressor and the heat exchange capability of the outdoor heat exchanger based on the respective deviation values between the respective detected values and the respective set values, which are obtained as the results of the comparison.

摘要： An air conditioner including an outdoor unit, indoor units, and a relay device for connection between the outdoor unit and each of the indoor units. The outdoor unit includes an outdoor heat exchanger, a compressor for pressurizing a refrigerant of or including carbon dioxide, and a first switching member for switching flow direction of the refrigerant through the outdoor heat exchanger. Each of the indoor units includes an indoor heat exchanger and first flow controller in fluid communication between first and second pipe connection ports. The relay device includes second switching members, each of the second switching members selectively connecting the first pipe connection port of a respective indoor unit with the first or second connection end of the outdoor unit.
