Machine room air conditioner control system, machine room system and control method of machine room system

Abstract

The invention discloses a machine room air conditioner control system, a machine room system and a control method of the machine room system. The control system comprises an integrated controller (20), a distributed controller (22), a water chilling unit (30) and external equipment (40), wherein the integrated controller (20) is used for controlling operation of the water chilling unit (30), and the distributed controller (22) is matched with the water chilling unit (30) and the external equipment (40) and used for controlling operation of the external equipment (40) of the water chilling unit (30) on the basis of the operation logic of the water chilling unit (30). According to the scheme, the defects that in the prior art, the number of functions is small, the failure rate is high and the stability is poor can be overcome, and the beneficial effects that the number of functions is large, the failure rate is low and the stability is good are achieved.

Description

technical field [0001] The invention belongs to the technical field of machine room refrigeration, and in particular relates to a control system of a machine room air conditioner, a machine room system and a control method thereof, in particular to a control system based on the control logic of a chiller, and a machine room system (that is, a modular machine room) with the control system. system), and the control method of the computer room system (that is, the modular computer room group control method). Background technique [0002] In the IT industry, the computer room can be a place where various servers and minicomputers are stored for telecommunications, Netcom, mobile, dual-line, electric power, government or enterprises, etc., to provide IT services for users and employees. The group control systems on the market (for example: computer room group control system) generally only control the start and stop of the unit (for example: air conditioning unit), and do not con...
