Heat recovery unit is a heat and moisture exchange between dirty indoor air and fresh outdoor air, recovering energy from the exhaust air. The recovered energy is used for pre-treatment (pre-cooling/pre-heating) of the supplied air, thus reducing the energy required for fresh air treatment, bringing in more fresh air at a lower cost, reducing energy consumption and lowering air conditioning operating costs. It is widely used for energy saving operation of air conditioning systems in all types of buildings, new air collection and retrofitting of air conditioning systems in old buildings.
