Re: Liquid Pump Low Dif
Usually, plan has outlet pressure regulator to keep certain constant(all year around) pressure in hot gas main. This is hot gas main. Evaporator has inlet pressure(or back pressure regulator) regulator to keep certain constant pressure inside the coil during defrosting. What do you have for new and old evaporators? What is the difference?
