七种新的R22替代物的变工况性能分析及实验

Analysises and Experiments of Some New Alternatives to R22

通过对各种环境可接受工质的循环特性、变工况性能优化分析提出几种Ｒ２２替代新工质。在房间热平衡实验台上对这些新工质进行了大量实验，得到了一种具有优良替代特性的Ｒ２２替代新工质。

Some new alternatives to R22 have been proposed according to their cycle performance and its variation character under different working conditions.The experimental evaluation of these new 'drop in'alternatives to R22 have been made with a room air conditioner by the method of Calibrated Room Type Calorimeter.The test results showed that one of them is more effective as the 'drop in 'alternatives.
