Waste heat recovery system for outside air
For colder climate applications, outside air ventilation must be preheated before entering the vents. The waste heat from exhausted air may be used for such purpose. Accomplished with the integration of a thermal wheel or rotary heat exchanger with the HVAC system.
21
Cooling heat recovery system
Heat exhausted from a cooling system could be recovered for ventilation and space heating. Accomplished using heat recovery condensers.
28
Air-source heat pump
Extracts heat from the air and then transfers heat to either the inside or the outside of your home depending on the season.
