摘要:
A cooling and heating concurrent operation type of mulitple refrigeration cycle comprises an outdoor unit (1) including a variable delivery type of compressor (2) and an outdoor heat exchanger (3); indoor units (5) including indoor heat exchangers (6a,6b,6c), respectively; triple connection pipes of a high pressure gas pipe (12), a high pressure liquid pipe (14) and a low pressure gas pipe (13), the triple connection pipes connecting between the outdoor unit and the indoor units; pressure detection means (20, 21) for detecting the intake pressure of the compressor (2) and the discharge pressure of the compressor; and calculation and control means (22) for comparing two detected values of the intake pressure and the discharge pressure of the compressor (2) with two set values of a set intake pressure and a set discharge pressure, and for making variable controls of the compression capabilitiy of the compressor (2) and the heat exchange capability of the outdoor heat exchanger (3) 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.
