source heat pump (GSHP) by using the counter flow and parallel flow methods. The GSHP uses R-410A as a refrigerant, and its … valve, a receiver, and an inverter. Based on our modeling results, the heat transfer rate of the counter flow evaporator is … compressor RPMs and source side EWT. Also, using the counter flow method, compared to the parallel flow method, improves the COP …
