What Is An Energy Recovery Ventilator?
Energy restoration air flow (ERV) is the power recuperation technique of changing the strength contained in usually exhausted constructing or house air and the usage of it to treat (precondition) the incoming outdoor air flow air in residential and commercial HVAC systems. During the hotter seasons, the system pre-cools and dehumidifies whilst humidifying and pre-heating in the cooler seasons. The benefit of the use of strength restoration is the capacity to meet the ASHRAE air flow & electricity standards, while enhancing indoor air fantastic and reducing whole HVAC equipment capacity.
This technology has no longer only established an fine potential of lowering power fee and heating and cooling loads, but has allowed for the scaling down of equipment. Additionally, this system will permit for the indoor surroundings to maintain a relative humidity of 40% to 50%. This vary can be maintained underneath really all conditions. The only strength penalty is the strength wished for the blower to overcome the pressure drop in the system.
