Summary

Three different reversing methods are examined. Two of these methods use four-way reversing valves and the third method involves redirection of heat transfer fluid between the condenser and the evaporator to implement change of mode. The third method appears to be the best reversing technique for both refrigerants considered. With all three methods, in the reversed mode, the R407C system performs better than the R134a system over a large range of volume ratios.
