Heat Recovery Ventilation
Midea heat recovery ventilation ensures effective fresh air in any application. The exceptionally quiet units can greatly reduce energy losses and room temperature fluctuations caused by the ventilation process.
Midea heat recovery ventilation (HRV) can greatly reduce energy losses and room temperature fluctuations caused by the ventilation process. Temperature exchange efficiency is over 74% and enthalpy exchange efficiency is over 76%.
Soundproofing is used to guarantee quiet operation.
HRV can be controlled together with other indoor units. Heights starting from as little as 264mm and weights from as little as 23kg mean that the HRV can be easily installed where space is limited.
Heat Exchange Mode: The flows of incoming and outgoing air pass close to each other, allowing heat transfer between the two channels.
During summer, incoming air is cooled by the indoor air being exhausted
and in winter, incoming air is warmed.
Bypass Mode: Supply and exhaust fans run at the same speed. In mild climates, where temperature and humidity differences between indoor and outdoor are small, the HRV can work as a conventional ventilation fan.
Air Supply Mode: Supply fan runs faster than exhaust fan. A mode suitable in mild climate installations with fresh air ventilation requirements.
Exhaust Mode: Exhaust fan runs faster than supply fan. A mode
suitable in mild climate installations with large amounts of exhaust air to be expelled.
Auto Mode: The controller chooses heat exchange mode or bypass mode according to temperature difference between outdoors and indoors. Both fans run at low speed.
