I am currently putting together a 1 1/2ton chiller unit. The design of this system encorporates a liquid line, hot gas solenoid, heat exchanger and txv. The point of the hot gas bypass is to level out the temp of the fluid being cooled through the heat exchanger as well as prevent the heat exchanger from freezing up. I'm having a problem where even when I open the hot gas bypass valve going into the inlet of the evaporator, the temp is still dropping. The txv is overcoming the hot gas coming in and still maintaining a temp drop. Any comments?
