Description

A heat recovery fresh air fan

Technical field:

The utility model relates to an air conditioning device, in particular to a heat recovery fresh fan with multiple channels.

Background technique:

With the modernization of industrial and agricultural production and the rapid improvement of people's living standards, air conditioners have been widely used in public places, enterprises, institutions and families, creating a working and social living environment that is warm in winter and cool in summer for people. But because the air-conditioning room is airtight for a long time, there is no fresh air exchange with the outside world, so that the indoor air is polluted and dry, so many people suffer from "air-conditioning disease", which endangers people's health. But in the severe winter and hot summer, if you open the doors, windows or ventilation fans, the cold wind in winter and the hot wind in summer will penetrate, and the indoor temperature will fluctuate greatly, which is unbearable for people and equipment.

Utility model content:

The technical problem to be solved by the utility model is: to solve the above-mentioned existing problems in the prior art, and to provide a kind of air conditioner suitable for exchanging fresh air with the outside world in four seasons in spring, summer, autumn and winter, recovering heat in winter and summer and saving energy, keeping the indoor temperature stable, comfortable and pleasant, and beneficial to people's health. Heat recovery fresh air fan.

The technical solution adopted by the utility model is: the heat recovery fresh air machine is equipped with a one-stage or two-stage dust collector, a plate heat exchanger, a fresh air fan, and an exhaust fan in the casing, and a fresh air inlet, Exhaust air outlet, fresh air outlet, and exhaust air inlet. A new and old air passage partition and an indoor circulation bypass valve plate are installed between the exhaust air inlet passage and the fresh air outlet passage in the casing. There is a fresh air straight-through passage on one side of the exhaust air outlet passage. The fresh air is directly connected to the valve plate, the exhaust air inlet channel and the exhaust air outlet channel are connected with one channel of the plate heat exchanger, the fresh air inlet channel and the fresh air outlet channel are connected with the other channel of the plate heat exchanger, and the dust collector is installed in the fresh air inlet channel Or/and in the fresh air outlet channel.

In the above technical solution, an infrared human body sensor and its controller are installed in the heat recovery fresh air fan and/or indoors. When there is no one in the room, it will be automatically shut down by the controller, and when there are people in the room, it will be automatically turned on by the controller.

In the above technical scheme, the plate heat exchanger can adopt the existing technology products, such as the plate heat exchanger manufactured by Changsha Yuanda Air Conditioning Co., Ltd., and the dust collector can also adopt the existing technology products, such as the high-voltage electrostatic precipitator manufactured by Changsha Yuanda Air Conditioning Co., Ltd. .

Main features of the utility model:

1. An electrostatic precipitator is installed in the heat recovery fresh air fan to improve the quality of fresh air;

2. In particular, high-voltage electrostatic precipitators are installed in the fresh air inlet channel and the fresh air outlet channel of the heat recovery fresh air fan, becoming a heat recovery fresh air fan with dual electrostatic precipitators;

3. There is a fresh air direct channel, which is controlled by the opening and closing of the fresh air direct valve plate, so as to adapt to the fresh air ventilation in spring and autumn except winter and summer, and the energy saving effect is obvious;

4. It also has a new and old air channel partition and an indoor circulation bypass valve plate that can directly carry out indoor air circulation to realize the indoor circulation bypass channel.

5. Infrared human body sensors are installed indoors or in the machine to realize automatic shutdown when no one is in the room and automatic startup when someone is in the room, humanized energy-saving control.

6. The utility model can improve the indoor air quality of the air conditioner, replenish fresh air in time without causing large fluctuations in the indoor temperature, keep the indoor temperature stable, comfortable and pleasant, and benefit people's health. Moreover, the utility model has multiple channels and functions, adapting to different seasons, different The working conditions of regions and different environments have excellent technical performance.
