Air purifier with double running modes

Abstract

The invention discloses an air purifier with double running modes. The air purifier comprises a shell and a controller, wherein a fresh air channel, an air return channel and a heat exchanger are arranged in the shell; the fresh air channel and the air return channel are connected with the heat exchanger respectively; an electrostatic dust remover is arranged in the fresh air channel; a first electric air valve is connected between the fresh air channel and the air return channel; a second electric air valve is arranged at an air inlet; the controller controls the first electric air valve and the second electric air valve; when the first electric air valve starts, the controller controls to stop an exhaust fan; and when the second electric air valve stars, the controller controls to operate an air feeder and the exhaust fan. The air purifier with double running modes can realize switching of an indoor air circulation purification mode and a fresh air purification mode, achieves a good air purification effect and can reduce the energy consumption of air temperature treatment.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air purifier with dual operation modes. Background technique [0002] With the acceleration of industrialization and modernization, air pollution is becoming more and more serious, especially the inhalable particulate matter such as PM2.5, which is very harmful to human health. People spend most of their life indoors, and the quality of indoor air directly affects people's health. It is a very urgent need to remove pollutants such as PM2.5 in indoor air. [0003] In order to improve indoor air quality, an air purifier has been developed in the prior art. After the indoor air is purified through steps such as dust removal, sterilization, and filtration, it is discharged into the room, so that the indoor air forms a circular flow. The long-term circulation of indoor air will reduce the oxygen content in the air, increase the number of bacteria, and reduce the quality ...

AI Technical Summary

Problems solved by technology

However, when the weather is extremely cold or hot outside, the temperature difference between the outdoor and the indoor is relatively large. When the outdoor air is introduced into the room to improve the air quality, it will inevitably increase the energy consumption of the air temperature treatment, such as air conditioning energy consumption; and when the weather is bad outside, the introduction of fresh air will reduce the comfort of people indoors

With the further deterioration of the environment, the current annual extreme weather time accounts for 1 / 3 of the whole year. Therefore, the use of new fans will greatly increase the temperature of the air and the energy consumption.
