CHICAGO — Four-way reversing valves are at the heart of heat pump systems, and are indeed necessary to their function. An ASHRAE technical committee is looking for input as to how much capacity is lost through their operation, and how it should be tested.
The forum, “Are Internal Leakage and Heat Transfer Required in a Standard for Method of Testing for Capacity of Four-Way Reversing Valves,” asked these “essential” questions:
