Method for jointly controlling indoor fresh air volume through air conditioner and automatic window

Abstract

The invention relates to a method for jointly controlling the indoor fresh air volume through an air conditioner and an automatic window. The method comprises the following steps that (1) the indoor temperature is monitored; (2) when the indoor temperature is not within the preset temperature range, the automatic window is controlled to be closed, the air conditioner is started, and meanwhile, the indoor carbon dioxide concentration is monitored; and (3) when the monitored indoor carbon dioxide concentration reaches a preset concentration upper limit value, the automatic window is controlled to be opened by a preset opening degree, and outdoor fresh air is introduced into a room; and when the monitored indoor carbon dioxide concentration reaches a preset value, the automatic window is controlled to be closed, and the air conditioner is controlled to regulate the room temperature. According to the method, the function of the air conditioner is utilized, the room can be cooled in summer and heated in winter, outdoor fresh air can be introduced according to the change of CO2 concentration or indoor and outdoor temperature and humidity parameters in combination with a natural ventilation mode, a special fresh air unit or a central air conditioner is not needed for processing the fresh air, and the requirement of personnel on the fresh air volume is met.

Description

technical field [0001] The invention belongs to the technical field of home appliance control, and in particular relates to a method for jointly controlling indoor fresh air volume by an air conditioner and an automatic window. Background technique [0002] The annual output of household air conditioners in my country exceeds 150 million units, and air conditioners have become a necessity for families. However, people who have been in an air-conditioned environment for a long time are prone to air-conditioning diseases, mainly because of imperfect architectural design, defects in air-conditioning itself, and people's over-reliance on air-conditioning. [0003] In response to this problem, most domestic manufacturers currently use inverter air conditioners to control the temperature fluctuations in the room, which can partially improve the defects of air conditioner temperature control, but use indoor circulating air, which is difficult to meet the requirements of fresh air v...

However, people who have been in an air-conditioned environment for a long time are prone to air-conditioning diseases, mainly because of imperfect architectural design, defects in air-conditioning itself, and people's over-reliance on air-conditioning.

[0003] In response to this problem, most domestic manufacturers currently use inverter air conditioners to control the temperature fluctuations in the room, which can partially improve the defects of air conditioner temperature control, but use indoor circulating air, which is difficult to meet the requirements of fresh air volume for personnel; A fresh air unit is added separately in the room to meet the requirements of fresh air, which will increase the consumption of the fresh air unit and cost a lot; while the central air conditioner centrally processes the air and can generally provide some fresh air, but it is suitable for large-scale applications. Too much power consumption, not suitable for ordinary household use
