They’ve been around for many years, starting in the commercial sector, then appearing … Energy recovery ventilation (ERV) is the energy recovery process in residential and commercial HVAC systems that exchanges the energy contained in normally exhausted air of a building or conditioned space, using it to treat (precondition) the incoming outdoor ventilation air. The specific equipment involved … See more Nearly half of global energy is used in buildings, and half of heating/cooling cost is caused by ventilation when it is done by the "open window" method according to the regulations . Secondly, energy generation and grid … See more An ERV is a type of air-to-air heat exchanger that transfers sensible heat as well as latent heat. Because both temperature and moisture are transferred, ERVs are described as total enthalpic devices. In contrast, a heat recovery ventilator (HRV) … See more Fixed plate heat exchangers have no moving parts, and consist of alternating layers of plates that are separated and sealed. Typical flow is cross current and since the majority of plates are solid and non permeable, sensible only transfer is the result. See more The efficiency of an ERV system is the ratio of energy transferred between the two air streams compared with the total energy transported through the heat exchanger. See more The rotating wheel heat exchanger is a rotating cylinder filled with an air permeable material, typically polymer, aluminum, or synthetic fiber, providing the large surface area … See more • Delta's PM2.5 Energy Recovery Ventilator (ERV) • http://www.engineeringtoolbox.com/heat-recovery-efficiency-d_201.html See more
