Performance domain of multiple-split air conditioning systems

Puts forwards the description method of the indoor load distribution characteristics. Taking the multiplesplit air conditioning (MSAC) system with the indoor units whose capacity is continuously regulated in refrigeration conditions as example, studies the influence of indoor load distribution unevenness on the part load performances of the MSAC system. Finds that when the indoor and outdoor conditions keep constant, the COP of the system will be within a performance domain related to the system load ratio and the indoor load unevenness index. Analyses the factors influencing the shape of the performance domain.
