A compound refrigeration system is provided for use with a thermal storage system. anglais. In a vapour compression refrigeration system, the compressor plays a key role on the power consumption and its overall performance is a result of electrical, mechanical and thermodynamic efficiencies. Compression Ratio: In refrigeration it is the ratio of the absolute low-side pressure to the absolute high-side pressure. (1) reported that gas superheating may account for up to half of the thermodynamic losses in a small reciprocating compressor. The different stages in the refrigeration cycle are undergone in these physical systems. Compound chiller design (two compressors in series) ...

Advantages are in particular the saving of power accompanied by less costs. Complex compound refrigeration uses fixed sorber beds containing solid complex compounds as the sorbent. A new solar adsorption refrigeration system integrated with a compound parabolic concentrator (CPC) adsorber was proposed. The purpose of using a compound system is as the following: - Increase the refrigeration effect. Mechanical refrigeration, is the utilization of mechanical components arranged in a "refrigeration system" for the purpose of transferring heat. Compound multi stage systems are typically used where ultra low temperatures are desired but cannot be economically obtained through the use of a single stage system.
