Centralized control method of precise air conditioning system

Abstract

The invention discloses a centralized control method of a precise air conditioning system. The centralized control method comprises a temperature rise control method and a temperature reducing control method. The centralized control method of the precise air conditioning system has the following beneficial effects: on the basis of even indoor temperature distribution, arrangement of air conditioner at the same side of a machine room and a consistent space, the method establishes a mathematical relationship between the starting time of a single air conditioner and service life specific to a precise air conditioning system in the same one machine room scale, comprehensively considers the state of a plurality of precise air conditioners, and adjusts the opening and closing strategies at any time by taking the longest service life of the air conditioning system as a goal according to the change of the indoor temperature and humidity. On the basis of ensuring safe and stable operation of the machine room, the centralized control method, the centralized control method avoids the frequency start-stop of a single precise air conditioner, prolongs the service life of the air conditioning system, and saves the maintenance cost of the machine room; therefore, the centralized control method has strong economic value.

Description

technical field [0001] The invention belongs to the technical field of precision air-conditioning control, and in particular relates to a centralized control method of a precision air-conditioning system. Background technique [0002] The computer room usually houses various devices such as main servers, workstations, switches, and core routers. These devices consume a lot of power and generate a lot of heat. According to statistics, in the case of the base temperature, the reliability of the computer will drop by 25% for every 10°C increase in temperature. Therefore, in order to ensure the safety of the computer room, ensure the safe, stable and reliable operation of the information system, standardize the environment of the computer room, and avoid the safety risks caused by it to the greatest extent, it is necessary to control the temperature and humidity of the computer room within an appropriate range. The precision air conditioner is a precision air conditioner dedica...
