A method of room ventilation control based on exhaust fresh air fan

Abstract

The invention discloses a room ventilation control method based on an exhaust-type fresh air fan. Air-conditioning equipment, an exhaust-type fresh air fan and glass windows with ventilation functions are pre-installed in the room, and the room ventilation is realized according to the following operation control mode; 1) Indoor cooling and ventilation mode when the solar radiation is weak in summer, at this time, the outdoor air is controlled to flow from the upper outer air channel through the ventilation inner cavity of the glass interlayer and then flow out from the lower inner air channel; 2) Indoor cooling and ventilation mode when the solar radiation is strong in summer, at this time Outdoor air enters from the lower outer air duct, part of the air passes through the ventilation inner cavity and flows out from the upper outer air duct, and the other part of the air enters the room from the lower inner air duct; 3) Indoor heating and ventilation mode in winter, at this time the outdoor air is controlled The lower outer air duct enters, flows upward through the ventilation inner cavity, and then flows into the room from the upper inner air duct; the present invention can better improve indoor thermal insulation performance, reduce the energy load of house temperature control, and save energy and consumption.

Description

technical field [0001] The invention belongs to the technical field of building room ventilation, and in particular relates to a room ventilation control method based on an exhaust-type fresh air fan. Background technique [0002] With the improvement of people's material living standards, people have higher and higher requirements for the comfort of residential houses. Many high-end residential houses will install a fresh air system to regulate the temperature and ventilation in the house. At the same time, according to the latest national standard for civil building heating, ventilation and air conditioning design, it is clearly stipulated that all rooms in civil buildings need to consider the ventilation design requirements of a certain amount of fresh air, but at the same time, because this action will bring untreated outdoor air into the room and The air stagnated in the room is exhausted to the outside, so that the air conditioner must additionally undertake the work ...

AI Technical Summary

Problems solved by technology

In this patent, it seems that various functions such as air purification, temperature adjustment, and humidity adjustment are set on the windows, which improves the functionality of the windows, but in fact, the glass windows have their own functions of lighting inside the house and seeing through the outside, as well as the installation location, Restricted by size and other requirements, it is not suitable to directly integrate functions such as air purification, temperature adjustment, and humidity adjustment on windows, and the corresponding indoor environment control effect is far inferior to that produced by fresh air fans and air conditioners.

At the same time, after the interior of the double-layer glass is ventilated, only the electrostatic dust removal device is considered to clean the glass inner cavity, and its cleaning effect is limited. After long-term use, the glass inner cavity is difficult to clean, resulting in poor perspective and lighting effects.
