For such systems, it is essential to utilize energy recovery devices to reduce this load. Therefore, air-to-air fixed plate heat exchanger is used in buildings where the room exhaust air is passed in one stream and ambient fresh air is passed in the other stream of the heat exchanger.
All about home Ventilation, Heat Exchangers HRV's & ERV'sApr 12, 2012 · Energy Recovery Ventilation (ERV) is the process of exchanging the energy contained in normally fan extracted stale or humid air from homes and using it to treat (precondition) the incoming outdoor fresh air in residential and commercial HVAC systems. During warmer days, an ERV system pre-cools and dehumidifies while in the winter season ERV systems humidify and pre-heat incoming
Jul 30, 2019 · An air-to-air heat exchanger brings two air streams of different temperatures into thermal contact, transferring heat from the exhausting inside air to incoming outside air during the heating season. In summer, the heat exchanger can cool and in some cases, dehumidify the hot outside air passing through it and into the house for ventilation. The air-to-air heat exchanger removes the excess

WHAT IS AN AIR-TO-AIR HEAT EXCHANGER, HRV and ERV?May 16, 2014 · An air-to-air heat exchanger, or what is more commonly called today a Heat Recovery Ventilator (HRV), is a air change central ventilation system that exhausts stale air outdoors and brings in an equal quantity of fresh air to replace it while stealing the heat from the outgoing air to warm up the incoming air. See above for an animation on how that works.
In days past, energy was cheaper than insulation and builders used less care in insulating a home. As time progressed and energy prices increased, homeowners began to reduce costs by insulating attics, walls and basements, which stopped large-scale heat transfer. Recently, due to high energy costs and better materials, homeowners and builders are stopping the small air leaks around doors, windows,
Air to Air Heat Exchangers for Healthier Energy Efficient The equations for determining the amount of energy saved (Btu) in a year use the cfm, HDD, the efficiency rating of the heat exchanger (EF) and a constant for the specific heat and specific weight of air (25.92). The formula is as follows:Heat saved each year (Btu) = cfm x HDD
