Energy recovery ventilation is the process of exchanging the energy contained in a normally exhausted building or space air and using it to treat or "precondition" the incoming outdoor ventilation air in residential and commercial heating, ventilating, and air conditioning (HVAC) systems.
During the warmer seasons, the system pre-cools and dehumidifies, whereas during the cooler seasons, it humidifies and pre-heats.
The benefit of using energy recovery is the ability to meet the ASHRAE ventilation and energy standards while improving indoor air quality and reducing total HVAC equipment capacity.
High-performance Heat Recovery Ventilators (HRV) and Energy Recovery Ventilators (ERV) ensure a continuous ventilation supply and a comfortable and healthy indoor environment.
This technology not only demonstrates an effective means of lowering energy costs and heating and cooling loads, but it has also enabled HVAC equipment to be scaled down.
These energy recovery systems have attracted a lot of interest for industrial, office, and household applications.
Popular methods include air-to-air systems, in which heat recovered from the exhaust air stream is used to preheat incoming fresh air, and heat pumps, in which heat from the exhaust air stream is used to preheat the building's hot water or space heating system.
This course outlines the fundamental principles of heat and energy recovery systems.
This includes understanding the basic principles of various air-to-air energy recovery devices, as well as typical applications, calculations, advantages, and limitations.
