Room-level air conditioner adjustment method, device and controller

Abstract

The embodiment of the invention discloses a room-level air conditioner adjustment method, device and controller. Returned air temperature detected by a temperature sensor corresponding to each air conditioner is obtained, and then the rotation speed of a fan of each air conditioner is adjusted according to the difference between the obtained returned air temperature and a temperature threshold value until it is determined that the absolute value of the difference between the returned air temperature detected by the temperature sensor corresponding to each air conditioner and the temperature threshold value is smaller than a first set value; it is determined that the absolute value of the difference between the returned air temperature detected by the temperature sensor corresponding to each air conditioner in a room and the temperature threshold value is smaller than the first set value; when the absolute value of the difference between the rotary speeds of the fans of every two adjacent air conditioners is larger than a second set value, the smaller rotation speed of the fan of the air conditioner of every two adjacent air conditioners is adjusted. The probability that air blown by the fans with larger air pressure may get to the area with smaller air pressure is reduced.

Description

technical field [0001] The invention relates to the technical field of electrical control, in particular to a room-level air-conditioning adjustment method, device and controller. Background technique [0002] With the development of new technologies such as cloud computing, the heat density of information technology (English: Information Technology, IT for short) equipment is increasing, which puts forward higher requirements on the cooling capacity of the air conditioner in the computer room. However, in general, IT equipment does not keep running at full load. If the cooling equipment is still running at high load when the IT equipment is running at low load, it will inevitably cause energy waste. In order to improve energy efficiency, effective measures must be taken to adjust the operating status of the air conditioner in the computer room according to the load of the IT equipment to achieve on-demand cooling, that is, to ensure that the cooling capacity of the IT equip...

Problems solved by technology

[0005] However, in the computer room, room-level air-conditioning is used for cooling. If the equipment loads of different IT cabinets are different, there may be temperature differences in the computer room, resulting in different return air temperatures detected by each temperature sensor, and further resulting in different speeds of air-conditioning fans, resulting in wind. different pressure

A static pressure box is installed on the side of the air outlet of the air conditioner. Therefore, the wind blown by the fan with high wind pressure will flow to the area with low wind pressure, resulting in insufficient air volume in the area under its own responsibility to meet the load, resulting in hot spots. produce
