Air-conditioning control method and air-conditioning control device for closed equipment room

Abstract

The invention relates to an air conditioner control method and an air conditioner control device for a closed equipment room. The method comprises the steps that the indoor temperature is continuouslyobtained at a certain frequency; the indoor temperature is compared with a preset temperature threshold value, and if the indoor temperature reaches the temperature threshold value, a control signalis sent to an air conditioner; the duration time after the control signal is sent is obtained; and the duration time is compared with a preset time threshold value, and if the duration time reaches the time threshold value and meets a first preset condition, the control signal is sent to the air conditioner again. The method has the advantages that the indoor temperature of the closed equipment room is obtained and compared with the temperature threshold value, then the air conditioner is controlled to be started and shut down, long-time starting of the air conditioner is avoided, the use energy consumption of the air conditioner is reduced, electric energy is saved, and cost is greatly reduced; and the duration time after the control signal is sent is compared with the time threshold value, abnormal switching caused by electric power fluctuation is avoided, and electric energy is saved.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to an air-conditioning control method and an air-conditioning control device for closed equipment rooms. Background technique [0002] In the public area rooms such as power distribution rooms and elevator machine rooms in some residential quarters and commercial office buildings, the internal equipment needs to be within a certain temperature range to work properly. In order to cope with the high temperature in summer and the low temperature in winter, air conditioners are usually used for temperature regulation. [0003] In order to reduce the purchase cost in the early stage and the maintenance cost in the later stage, the property usually adopts cheap fixed-frequency air conditioners, and the energy consumption level is basically level 3 energy consumption. In summer and winter, the property will set the air conditioner to a certain fixed temperature, and then make ...

AI Technical Summary

Problems solved by technology

[0005] In addition, in some occasional situations, due to external power fluctuations, it often leads to abnormal switching of the air conditioner, such as the self-starting of the air conditioner when it is powered on, resulting in waste of energy consumption

In this case, property management personnel are required to find out during inspections and perform manual switching, which will result in low efficiency and increased energy consumption.

[0006] In addition, in cloudy and rainy weather, the outdoor temperature is low. For public areas such as the elevator machine room on the roof, the property usually switches the air conditioner on and off. This operation has potential safety hazards and is likely to cause harm to the life and health of property personnel.
