Multifunctional air ventilation and purification machine as well as operation control method

Abstract

The invention relates to the field of air ventilation and purification systems for buildings, in particular to a multifunctional air ventilation and purification machine as well as an operation control method. The multifunctional air ventilation and purification machine comprises a machine body housing as well as an outdoor-to-indoor air flow channel, an indoor-to-outdoor air flow channel and an indoor-to-indoor air flow channel which are positioned in the machine body housing, wherein the air circulation area on two sides of a proportional air valve is controlled by controlling the sliding ofthe proportional air valve through a motor, and then the air volume of the outdoor-to-indoor air flow channel and that of the indoor-to-indoor air flow channel are adjusted; and multi-effect filter screens, an electric heater, a heat exchanger, an air blower, an air exhaust fan, a sterilization module, a sensor module, a data transmission module, a control module and a control panel are also arranged in the machine body housing. According to the operation control method, the intelligent operation of such a unit is achieved by monitoring and judging various indoor and outdoor environment parameters. The multifunctional air ventilation and purification machine as well as the operation control method have the beneficial effects that the intelligent operation of the unit can be achieved by monitoring and judging the various indoor and outdoor environment parameters; various operation modes can be provided; the manual intervention in the operation is not needed; and one machine can serve several purposes.

Description

technical field [0001] The invention relates to the field of fresh air purification systems for buildings, in particular to a multifunctional fresh air purifier and an operation control method thereof. Background technique [0002] People spend most of their life indoors in buildings. The indoor air quality will be affected by various factors such as outdoor atmosphere, interior decoration materials, and personnel activities. Breathing polluted air for a long time will affect human health and cause human respiratory diseases. Therefore how to improve the indoor air quality has been paid more and more attention by people. The fresh air fan is one of the devices that introduces outdoor fresh air into the room and renews and discharges the indoor dirty air, which can effectively reduce indoor CO 2 , VOCs (volatile organic compounds, volatile organic compounds) and other harmful gas content, increase the oxygen content. In order to ensure the cleanliness of the fresh air intro...
