在热化循环中应用混合工质R22／R152_a同时供冷与供热的实验研究

On thermaliztion cycle for heating and cooling with mixture substances R22/R152_a

通过在同时供冷与供热的热化循环装置中应用混合工质Ｒ２２／Ｒ１５２ａ及单一工质Ｒ１２进行实验研究，确定当ｃｏｐ值最高时其最佳的混合比，并用Ｒ１２作比较，证明在一定的热化循环工况下．混合工质总的能效比高于单一工质的总能效比。

Through the studying on thermalization cycle with mixture subtances R22/R152.and refrigerate R12 for heating and cooling,the optimal ratio of mixture is obtained when the system's COP is highest. Bycomparing the experimental results between using refrigerate R12 and using the mixture substance,the result shows that the whole energy efficiency ratio of using the mixture substances is higher than that of using the refrigerate R12.
