Suspended ceiling fresh air ventilator energy-conservation control system and energy-conservation control method thereof

Abstract

The invention relates to the field of indoor air adjustment, in particular to a suspended ceiling fresh air ventilator energy-conservation control system and an energy-conservation control method thereof. The system and method are mainly achieved through an intelligent mode of an intelligent control module, in the intelligent mode state, an air quality sensor module and an air temperature module send detected air quality data and indoor and outdoor air temperature data to a microprocessor, the above detected air quality data and indoor and outdoor air temperature data are compared with a preset air quality setting value and indoor air temperature setting value through the microprocessor, and a fresh air motor, an exhaust motor and a switching valve are controlled to work. By means of the suspended ceiling fresh air ventilator energy-conservation control system and method, a suspended ceiling fresh air ventilator can monitor indoor and outdoor temperature, indoor air replacement, purification and flowing can be achieved, and energy conservation can be better achieved.

Description

technical field [0001] The invention relates to an energy-saving control system and an energy-saving control method for a suspended ceiling fresh air ventilator, belonging to the field of indoor air conditioning. Background technique [0002] At present, with the improvement of human living standards, air conditioners have entered thousands of households, offices, public places, and even various means of transportation. However, since the places where air conditioners are installed usually have better sealing effects, the harmful substances released by construction, decoration, furniture, decoration and office equipment will cause indoor pollution and lead to a decrease in air quality. In addition, people rely more on air conditioning and indoor heating in summer and winter, resulting in poor indoor ventilation, indoor harmful gases cannot be released and replaced, harmful gases continue to accumulate, and their concentrations continue to increase, eventually leading to dete...

AI Technical Summary

Problems solved by technology

[0005] If the outdoor air temperature is too high or too low in summer or winter, the user will use the air conditioner for cooling or heating. 2.5 If the concentration exceeds the standard, then the traditional ceiling fresh air ventilator is turned on to introduce fresh air from the outside to reduce the indoor particle concentration. Although the heat exchange efficiency of the traditional ceiling fresh air ventilator can reach 60% to 70%, there is still 30% to 40%. If there is an air purifier at this time, it can not only solve the problem of excessive indoor particulate matter concentration, but also will not cause indoor energy loss

However, if the user purchases the traditional ceiling fresh air ventilator and the air purifier at the same time, the cost will be greatly increased. If only the traditional ceiling fresh air ventilator is purchased, in some environments, unnecessary energy loss will be caused

[0006] In addition, in the summer evening, the outdoor air temperature drops, but because the room is relatively closed, the indoor ambient temperature is relatively high, and the traditional ceiling fresh air ventilator cannot monitor the outdoor air temperature. Fresh air reduces indoor air temperature, causing unnecessary energy loss

[0007] In the same scene, in the winter afternoon, the sun is directly shining, and the outdoor air temperature rises, but because the room is relatively closed, the indoor air temperature is relatively low, and the traditional ceiling fresh air ventilator cannot monitor the outdoor air temperature. It is impossible to introduce warm fresh air from the outside to increase the indoor air temperature, which also causes unnecessary energy loss

[0008] To sum up, traditional ceiling-mounted fresh air fans cannot monitor indoor and outdoor temperatures, and cannot introduce outdoor air when the outdoor air temperature can meet indoor needs. In addition, traditional ceiling-mounted fresh air fans can only replace indoor and outdoor air. To achieve air purification, it is impossible to achieve indoor PM similar to that of air purifiers 2.5 Circular purification, causing unnecessary energy loss in the above cases
