Method, device and controller for room-level air conditioning adjustment

Abstract

The embodiment of the invention discloses a room-level air conditioner adjustment method, device and controller. In the embodiment of the present invention, the return air temperature detected by the temperature sensor corresponding to each air conditioner is obtained, and the fan speed of each air conditioner is adjusted according to the difference between the obtained return air temperature and the temperature threshold until it is determined that The temperature sensor corresponding to each air conditioner detects that the absolute value of the difference between the return air temperature and the temperature threshold is less than the first set value; determine the return air temperature detected by the temperature sensor corresponding to each air conditioner in the room and the temperature threshold The absolute value of the difference is less than the first set value; when the absolute value of the difference between the fan speeds of any two adjacent air conditioners is greater than the second set value, the air conditioner with the smallest fan speed among the two adjacent air conditioners The speed of the fan is adjusted. It reduces the possibility that the wind blown by the fan with high wind pressure will cross wind to the area with low wind pressure.

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
