Abstract

The invention discloses a heat-recovery fresh air ventilator. The heat-recovery fresh air ventilator comprises a heat-recovery ventilator body, an air supply fan and an exhaust fan. The heat-recovery ventilator body is in a long strip shape. An air port of the air supply fan faces the left side of the heat-recovery ventilator body. An air port of the exhaust fan faces the right side of the heat-recovery ventilator body. The heat-recovery fresh air ventilator is characterized by further comprising a condensate pipe, a wet film cooling system and a heat exchange core body. The wet film cooling system comprises a wet film and a water distributor. A water inlet pipe of the condensate pipe is arranged at the top end of the wet film. A condensate plate is arranged at the bottom of the wet film. The bottom end of a drain pipe of the condensate pipe is arranged in the condensate plate. The heat exchange core body is connected to the middle portion of the heat-recovery ventilator body in a clamped mode. The air supply fan and the exhaust fan are arranged on the left side and the right side of the heat exchange core body correspondingly. The heat-recovery fresh air ventilator with the wet film humidifying and cooling functions is applied to a fresh air ventilating system, the air outlet temperature of the fresh air ventilator is decreased, and the fresh air load is reduced; and the cold energy in condensate of an air conditioner is recycled, and the cooling capacity is improved.

Description

technical field [0001] The invention relates to a heat recovery fresh air fan, in particular to a return air heat recovery device utilizing wet film cooling to increase efficiency, and belongs to the technical field of small household fresh air ventilators. Background technique [0002] With the rapid improvement of people's living standards, people pay more and more attention to the comfort and health of the indoor environment. While regulating the temperature and humidity of the air, there are also requirements for indoor air quality. In this context, small household fresh air ventilators are being accepted and paid attention to by more and more families. [0003] In the indoor cooling and heating load, the fresh air load can often account for about 35%. For some particularly cold and hot areas, the indoor and outdoor temperature difference is large, and the fresh air load will account for a larger proportion of the entire air conditioning operating load. Under the socia...
