Haze eliminating fresh air system based on electrostatic dust removing filter and control method of haze eliminating fresh air system

Abstract

The invention discloses a haze eliminating fresh air system based on an electrostatic dust removing filter and a control method of the haze eliminating fresh air system. The method includes the steps that the outdoor humidity phi is monitored, and if phi is smaller than or equal to phi 1, the electrostatic dust removing filter is turned on, fresh air is supplied, passes the electrostatic dust removing filter and flows indoors; and if phi is larger than phi 1, the electrostatic dust removing filter is kept turned off, fresh air is supplied through a bypass fresh air pipe, and meanwhile the first step is executed again so that the electrostatic dust removing filter can be controlled to be turned on or off according to the outdoor humidity. The electrostatic dust removing filter and the bypass fresh air pipe are arranged on an air supply pipe of the system, the bypass fresh air pipe and the electrostatic dust removing filter are connected in parallel, and the bypass fresh air pipe, the electrostatic dust removing filter and the air supply pipe are communicated with one another through a three-way electromagnetic switching valve. The haze eliminating fresh air system further comprises a humidity sensor and a control device. The humidity sensor is arranged outdoors and connected with the control device. The control device is connected with the three-way electromagnetic switching valve and a turn-on and turn-off control valve of the electrostatic dust removing filter. The haze eliminating fresh air system has the beneficial effects of being convenient to use, capable of saving energy and the like.

Description

technical field [0001] The invention relates to the field of indoor air purification, in particular to a haze removal fresh air system based on an electrostatic dust removal filter and a control method thereof. Background technique [0002] The haze removal fresh air system with the electrostatic dust removal filter can send the outdoor air into the room through the air supply port of the haze removal fresh air system after the haze removal and purification, and at the same time, the air exhaust port discharges the indoor air to the outside, thereby improving the indoor air quality, but In actual use, if the outdoor humidity is high, the electrode plate of the electrostatic precipitator filter cannot be powered and stops working. Once the electrostatic precipitator filter stops working, it is impossible to judge when the electrostatic precipitator filter can be started again, so that the The use of the haze fresh air system is very inconvenient. If you try to activate the el...

[0002] The haze removal fresh air system with the electrostatic dust removal filter can send the outdoor air into the room through the air supply port of the haze removal fresh air system after the haze removal and purification, and at the same time, the air exhaust port discharges the indoor air to the outside, thereby improving the indoor air quality, but In actual use, if the outdoor humidity is high, the electrode plate of the electrostatic precipitator filter cannot be powered and stops working. Once the electrostatic precipitator filter stops working, it is impossible to judge when the electrostatic precipitator filter can be started again, so that the The use of the haze fresh air system is very inconvenient. If you try to activate the electrostatic precipitator filter many times when the outdoor humidity is high, it will cause energy waste
