Comparative Analysis of Energy Efficiency in Air-conditioning System with GSHP, Electricity-driven Refrigerating Unit and Direct-fired Li-Br Absorption Refrigerating and Heating Unit

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....

Performance of a Solar LiBr - Water Absorption Refrigerating Systems

Up to now, the production of the cold is undertaking mainly by the classical way of compression refrigerator cycle. The cycle need an electrical power or mechanics expense for the training of the compressor and the C.F.C for their functioning. Most of the C.F.C impoverish the layer of ozone and participate with a considerable manner, to the increase of the sere effect, then to climatic changes....
