A window-type sensible heat exchange fresh air fan

Abstract

The invention discloses a window type sensible heat exchange fresh air ventilator, which comprises a body, a heat exchange part, a fresh air filtering device, an exhaust air filtering device, a freshair humidity adjusting device and a controller. The heat exchange part, the fresh air filtering device, the exhaust air filtering device, the fresh air humidity adjusting device and the controller arearranged in the body. The heat exchange part is used for carrying out heat exchange on indoor exhaust air and outdoor fresh air; the fresh air filtering device is used for filtering outdoor fresh air; the exhaust air filtering device is used for filtering indoor exhaust air; the fresh air humidity adjusting chamber is used for selecting whether to humidify or dehumidify the outdoor fresh air subjected to heat exchange. The window type sensible heat exchange fresh air ventilator is a two-way flow type fresh air ventilator, indoor exhaust air and outdoor fresh air can be subjected to heat exchange after being filtered, after heat exchange is finished, the outdoor fresh air is fed into a room, the indoor exhaust air is exhausted out of the room, the fresh air humidity adjusting chamber is arranged, and the outdoor fresh air can be humidified or dehumidified.

Description

technical field [0001] The invention relates to the technical field of fresh air fans, in particular to a window-type sensible heat exchange fresh air fan. Background technique [0002] In recent years, due to the increasingly serious air pollution, problems such as smog, influenza and carbon dioxide have made the problem of air pollution more and more prominent, and people's requirements for quality of life are getting higher and higher. General air purifiers can no longer meet people's needs for air purification. The need of the new air system is gradually becoming the rigid demand of modern homes. Most of the existing window-type fresh air fans on the market are one-way flow fresh air fans. The one-way flow fresh air fans fill the outside air into the room, and the air intake is greater than the air output, so that the indoor air pressure is higher than the outdoor air pressure, forming a slightly positive air pressure. Under the action of air pressure, the indoor air fl...

[0002] In recent years, due to the increasingly serious air pollution, problems such as smog, influenza and carbon dioxide have made the problem of air pollution more and more prominent, and people's requirements for quality of life are getting higher and higher. General air purifiers can no longer meet people's needs for air purification. The need of the new air system is gradually becoming the rigid demand of modern homes

Most of the existing window-type fresh air fans on the market are one-way flow fresh air fans. The one-way flow fresh air fans fill the outside air into the room, and the air intake volume is greater than the air output volume, so that the indoor air pressure is higher than the outdoor air pressure, forming a slightly positive air pressure. Under the action of air pressure, the air in the room flows to the outside through the gaps in the doors and windows, but the one-way fresh air fan purifies the outside air and introduces it into the room, which can effectively prevent outdoor harmful substances from entering the room, but it is difficult to remove the dirty indoors. The air is taken out, making the ventilation effect not very good
