Item # R6K, Aquefier Series Heat Recovery Units (1.5 to 5 tons)

HEAT RECOVERY UNIT FOR DOMESTIC HOT WATER FROM RESIDENTIAL HVAC SYSTEMS

The AQUEFIER® Heat Recovery Unit captures waste heat discharged from the refrigerant cycle in an Air Conditioning or Heat Pump system, and transfers that heat into a water heater tank, thereby creating low cost hot water for domestic use. Not only does the Heat Recovery Unit substantially reduce the amount of energy required to provide domestic hot water, but it also improves the cooling efficiency of the Air Conditioner or Heat Pump while it is operating. The Model R6K is designed to operate with systems of 18,000 to 60,000 Btu/hr (1-1/2 to 5 ton) cooling capacity.

Application

The refrigerant side of the Heat Recovery Unit Heat Exchanger is installed in the refrigerant hot gas line between the compressor and condenser; or between compressor and reversing valve, if installed on a Heat Pump System. The water side of the Heat Exchanger is connected to the water heater tank to form a circulation loop. Power is drawn from the compressor contactor. Waste heat may be collected when the compressor operates, and the water circulating from the water heater tank is less than 140ºF. A minimum refrigerant temperature of 125ºF is also required to allow Heat Recovery operation.

APPLICATION CAUTION: Installations subject to freezing ambients must make provision for freeze protection. Heat Recovery Units containing freezestats must draw power

from the line side of the compressor contactor. Drainable hand valves are a more positive freeze protection approach.
