AIR-TO-WATER HEAT PUMPS (AWHP)

What Is an Air-to-Water Heat Pump?

A key part of our air-cooled chiller portfolio, these heat pumps achieve reliable year-round cooling and heating by transferring energy between their internal fluid and the outside air. With their refrigerant reversing valves, they’re able to switch between cooling and heating modes as needed based on outdoor temperatures or your preferences.

Both effective and affordable, an air-to-water heat pump system doesn’t need to be overly complex to successfully operate. Trane can deliver design concepts and control sequences that are highly flexible, reliable and efficient today and tomorrow.
