EER and Refrigerating Capacity of Dual Split Type Air-Conditioner

There are two kinds of dual split type air-conditioner. One is of using two compressors for two indoor units; the other has only one compressor for two indoor units. The EER and refrigerating capacity of the former kind are just the same as the single split type's. But to one compressor dual split type system, there are two working ways: 1. compressor and both two indoor units operating, and 2. compressor and only one indoor unit operating. In these two ways the EER and refrigerating capacity of the system are different. In this paper, the EER and refrigerating capacity of one compressor dual split type air-conditioner are discussed.
