An indoor air ventilation device

Abstract

Disclosed is an indoor air ventilating device. The indoor air ventilating device comprises an upper air outlet at the upper end of a wall, a lower air outlet at the lower end of the wall, an outdoors-arranged heat exchanging tank I with the inside closed by the surrounding and filled with conduction oil, thermal insulating layers arranged on the inner walls of the heat exchanging tank I, and heat exchanging pipes I and II arranged inside the heat exchanging tank I and immersed inside the conduction oil. External air is fed into the heat exchanging pipe I through an air supply pump and indoor air is fed into the heat exchanging pipe II through a sucking pump; due to the fact of being immersed inside the conduction oil and connected with each other through thermal conductive silicon rubber, the heat exchanging pipe I and the heat exchanging pipe II can fully exchange heat; in summer, cold air sucked from the indoor can reduce the temperature of fresh outdoor air inside the heat exchanging pipe I and accordingly reduce the energy consumption of an indoor air-conditioner; in winter, hot air sucked from the indoor can heat the fresh outdoor air inside the heat exchanging pipe I, so that the temperature of air entering the indoor can effectively avoid being too low.

Description

Technical field [0001] The invention relates to the technical field of indoor air ventilation devices. Background technique [0002] As we all know, with air pollution, more and more families have purchased air purifiers to purify indoor air. However, without opening the windows for ventilation, the outdoor oxygen-rich air cannot be introduced into the room, which causes the problem that although the indoor air particle content is low, the oxygen content is also low. However, opening windows for ventilation will cause indoor PM2.5 and PM10 levels to exceed the standard. Some existing ventilators on the market that introduce outdoor air into the room cannot balance the temperature difference between indoor and outdoor, which easily causes the problem of blowing outdoor cold air into the room in winter and blowing outdoor hot air into the room in summer. Summary of the invention [0003] In order to overcome the shortcomings of the above technologies, the present invention provide...

Problems solved by technology

However, if the windows are not opened for ventilation, the oxygen-rich outdoor air cannot be introduced into the room, resulting in the problem that although the indoor air particle content is low, the oxygen content is also low.

However, opening windows for ventilation will cause indoor PM2.5 and PM10 levels to exceed the standard.

Some existing ventilation devices on the market that introduce outdoor air into the room cannot balance the temperature difference between indoor and outdoor, which easily leads to the problem of blowing cold outdoor air into the room in winter and blowing hot outdoor air into the room in summer
