Delta t for heat pumps
WebOct 16, 2024 · Generally, the delta T will be between 14 and 23 degrees, but that number can vary wildly depending on blower type and load conditions. HVAC equipment doesn’t just remove sensible heat; when water condenses on the evaporator coil, some latent heat is removed from the air. WebJun 11, 2011 · I just can't figure what variable would change to make the heat pump work less if the max delta-T is limited to 20 degrees by physics. If this thread would be better in another area, please suggest. Thanks Reply . 06-11-2011, 01:25 AM #2. mason. View Profile View Forum Posts View Forum Threads ...

WebJan 9, 2002 · January 9, 2002. Evaluating the performance of a heat pump in heating mode can be very difficult. The typical feedback we usually rely on in the cooling mode to determine how a system is operating (like pressures, subcooling and superheat) is much less valuable in heating mode. You can compare the operating pressures of the system … programs cleanerWebHeat pump: 32F delta T (67F return, 99F supply), outdoor temp 42F. Gas furnace: 58F delta T (68F return, 126F supply), outdoor temp 39F. I'm rather surprised the heat pump matched the gas furnace in heat rise rate.
