Rheem Air to Water / Water to Water Heat Pump
Air-to-Water Heat Pump
An air-to-water heat pump absorbs heat from the surrounding air and transfers it into the water line. Heat pumps transfer heat by circulating refrigerants through a cycle of evaporation and condensation- basically the reversed process of a household refrigerator where the heat energy produced is used for water heating and the by-product is cold air. This system yields a relatively high Coefficient of Performance (COP) in ASEAN countries having a minimum of 25°C ambient temperature, requiring less amount of electricity to generate heat for hot water use.
Water-to-Water Heat Pump
A water-to-water heat pump typically transfers heat from industrial water. In normal installations, water sources can be from the chiller side or cooling tower side of the building’s centralized air cooling system that provides a relatively constant heat source with which the heat pump utilizes the waste heat energy from other equipment and converts it to a heat source to generate heat more efficiently for hot water use.
