Linkage control method, device and equipment for air conditioners in machine room

Abstract

The invention discloses a linkage control method, device and equipment for air conditioners in a machine room, which can realize linkage control of room-level air conditioners, inter-row air conditioners and ventilation floors in the machine room and further optimize the airflow organization of the machine room. The method comprises the following steps: firstly obtaining machine room operation parameters, and then controlling a machine room refrigerating system to be freely switched among three modes of inter-row air conditioner independent operation, inter-row air conditioner and room air conditioner simultaneous operation and room-level air conditioner independent operation according to preset operation conditions met by the machine room operation parameters. Therefore, the method solves the problem that the room-level air conditioners and the inter-row air conditioners cannot operate in a linkage mode and switch the refrigeration mode according to the actual load, also solves the problem that the ventilation floor cannot be opened or closed in a linkage manner when the room-level air conditioners and the inter-row air conditioners are operated at the same time and the inter-row air conditioners are operated independently, and the problem that when the room-level air conditioners and the inter-row air conditioners operate at the same time, room airflow organization is disordered.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a linkage control method, device and equipment for an air conditioner in a computer room. Background technique [0002] With the development of new technologies such as cloud computing, the power density of computer equipment is getting higher and higher, which puts forward higher requirements for the cooling capacity of computer room air conditioners. [0003] At present, most of the old computer rooms use room-level air-conditioning and refrigeration systems. In order to increase the power density of the cabinets and reduce the generation of local hot spots in the computer room, micro-modules and inter-row air-conditioning systems are usually added when the computer room and cooling system are renovated. Row-level air conditioners usually use the horizontal air supply of the air conditioner, and generally operate the inter-row air conditioner according to the ch...

AI Technical Summary

Problems solved by technology

When the cooling capacity of the inter-row air conditioner is insufficient, and local hot spots in the micro-module need to be turned on, the room-level air conditioner needs to be turned on. According to the traditional control method, it is necessary to wait for the overall supply / return air temperature of the air conditioner to change before turning on the air conditioner for supplementary cooling. The traditional room-level air conditioner control method has a negative effect on temperature regulation. Lag, the local temperature of the micro-module cannot be sensed in time to provide cooling capacity in time

The traditional control method is independent control of room-level air conditioners and inter-row air conditioners, which cannot achieve good linkage control between inter-row air conditioners and room-level air conditioners, making the original room-level air conditioners and ventilation floors in the old remodeled computer rooms redundant and idle, resulting in waste of resources

[0004] In addition, inter-row air conditioners do not need ventilated floor during operation, while room-level air conditioners need to rely on ventilation under the floor to supply air to the machine room. Therefore, room-level and inter-row air conditioners are used at the same time, and ordinary ventilated floors cannot be opened according to inter-row air conditioners and room-level air conditioners. (OFF) while linkage ON (OFF)

After the computer room air conditioners in the two air supply modes are turned on, the micro modules are prone to wind field disturbance due to the different air supply modes of the two air conditioners, which is not conducive to good cooling of the cabinets, and the air conditioners are in low-efficiency operation, which needs to be adjusted in conjunction with the ventilation floor air supply

Ordinary ventilated floors cannot be linked to adjust the number of open floors, air supply volume and air supply angle according to the opening of the air conditioner
