摘　　要：随着R22替代期限的接近,替代制冷剂的研究更加紧迫。混合工质R407C各项性能与R22相当,可在系统稍做改变的前提下用于直接替代,这使得R407C的应用前景非常广泛。但R407C的COP略低于R22,这就需要加快对其换热器及系统的研究以提高其性能。It is pressing to study the ahemative refrigerants for R22 will be forbidden. The performance of R407C is similar to R22, so the refrigerant can be altered directly. R407C may be used very. popular because of the system should change little.The COP of R407C is lower than R22, so it should study on the heater exchange and system rapidly to improve the performance.
