Air exchanger with function of purifying indoor air

Abstract

The air exchanger with function of purifying indoor air has one box type shell with the front part set inside the room and the back part outside the room; indoor air inlet and air outlet in the front panel; dust filtering net, adsorbing active carbon net, photocatalyst filtering net and sterilizing lamp at the indoor air inlet; outdoor air inlet in the back cover of the shell; dust filtering net and adsorbing active carbon net at the outdoor air inlet; resonance preventing and heat insulating strip in the back of the shell; cross flow blower inside the shell; control circuit connected to the blower motor and remote controller for the remote control circuit. The present invention has the functions of ventilating, purifying indoor air and separating noise.

Description

technical field [0001] The invention relates to a ventilation device, in particular to a ventilation device with multiple functions such as ventilation, noise isolation, indoor air purification, and indoor / outdoor environment detection and control. Background technique [0002] Air conditioners and exhaust fans are familiar ventilation devices. Since the air conditioner system is in the process of adjusting the environment of the closed space, when the air conditioner is running for a period of time, the air quality in the closed space will decline, so the closed space needs to be ventilated through the ventilation device. Most of the existing ventilation methods use the built-in air quality sensor of the air conditioner to detect the indoor air and control the opening of the ventilation device. Although it can achieve the purpose of controlling ventilation, this method ignores the mutual influence between the ventilation device and the operation of the air conditioner. Th...

Problems solved by technology

Although it can achieve the purpose of controlling ventilation, this method ignores the mutual influence between the ventilation device and the operation of the air conditioner. The operation will generate air flow and cause the quality of the air to be uneven, so that the detection results of the air quality sensor will produce errors and there will be a dead angle of ventilation in the closed space

And this ventilation method usually cannot accurately control the ventilation volume and the quality of new air.

[0003] In addition, existing ventilation devices such as ventilation fans also have the following obvious defects: 1. Their use usually destroys the airtightness of confined spaces, especially in environments with high outdoor noise. Existing ventilation devices cannot effectively prevent outdoor ventilation. The noise is introduced into the room, and its installation will also destroy the sound insulation performance of the wall and vacuum glass

2. Existing ventilation devices usually cannot improve the indoor air quality by purifying the air in the closed space. When the ventilation demand in the closed space increases, the efficiency of the air conditioning system will be reduced, and the workload and cleaning of the air conditioning system will be increased. times, while shortening the effective service life of air-conditioning equipment

3. The existing air-conditioning and ventilation devices are usually used in conjunction with the air conditioner, and cannot independently and reasonably control the ventilation volume. When the outdoor temperature has reached a comfortable range, the air conditioner must also be turned on to achieve ventilation in a closed space, which will cause Energy waste
