Problems solved by technology

In the actual use process, due to the large temperature difference between indoor and outdoor, the fresh air introduced into the room from the outside will have a great impact on the indoor temperature, which reduces the comfort of the fresh air fan.
Another convenience is that if there are air conditioners and other temperature control equipment in the room, the outdoor wind with a large temperature difference introduced by the fresh fan will also increase the load on these temperature control equipment and increase energy consumption.

Abstract

The invention discloses a wall-hanging fresh air fan which comprises a shell. A fresh air port communicating with the outdoor, an air return port, and an air outlet are formed in the shell; the air return port and the air outlet communicate with the indoor; a fresh air fan, an air return fan and an air outlet fan are arranged on the fresh air port, the air return port and the air outlet; and onlyone of the air return port and the fresh air port can be opened at the same time. The wall-hanging fresh air fan further comprises an electrostatic precipitation device and a heat accumulator carryingout heat exchange with an air flow, wherein the electrostatic precipitation device and the heat accumulator are arranged in the shell. According to the wall-hanging fresh air fan with the structure,the heat accumulator is utilized for balancing the temperature difference between fresh air and indoor air so as to discharge air, so that the use comfort of the fresh air fan is greatly improved.

Description

technical field [0001] The invention relates to a fresh fan used for indoor air purification. Background technique [0002] With PM2.5 exposure and serious indoor air pollution. The country attaches great importance to the control of indoor air pollution, and has issued a series of national standards, requiring fresh air to be introduced into civil buildings and control of indoor air pollution. Summary of GB50736-2012 "Code for Design of Heating, Ventilation and Air Conditioning in Civil Buildings": "Heating, ventilation and air conditioning engineering is an indispensable part of the field of capital construction. Conditions and improving the quality of life all play a very important role. [0003] The function of the fresh fan is to exchange the outdoor air with the indoor air after sterilization and dust removal to achieve air purification. In the actual use process, due to the large temperature difference between indoor and outdoor sometimes, the fresh air introduced ...
