Experimental study of an R407C drop-in test on an off-the-shelf air conditioner with a counter-crossflow evaporator.

Author(s) : MEI V. C., DOMITROVIC R., CHEN F. C.

Summary

Laboratory tests were performed using a paralel-cross-flow (PCF) evaporator and a counter-cross-flow (CCF) evaporator. The CCF configuration is designed to take advantage of the temperature glide of R407C. Test results indicated that the cooling capacity was 8% higher and system COP about 3.8% higher for the CCF evaporator than for the PCF evaporator. The test results also showed that the latent load for CCF was 30.6% higher than for PCF. The far better dehumidification effect provided by the CCF evaporator design is desirable for areas where the latent load is high.
