Problems solved by technology

For the data center, the computer room of the data center has a large area, which requires multiple air conditioners to cool down. However, the isolated temperature control systems of multiple air conditioners will affect each other, resulting in poor temperature control effect in the data center computer room. Moreover, the heat dissipation of the servers in the data center computer room is large and unevenly distributed, and the independent temperature control of multiple air conditioners is difficult to deal with the problem of local hot spots; at the same time, the heat dissipation of the servers in the data center computer room will also change with the load. If the load changes rapidly, the independent temperature control method of multiple air conditioners is also difficult to deal with the problem of local rapid temperature rise

Abstract

This application provides a temperature control method and device for a multi-connected air-conditioning system. The temperature control method for a multi-connected air-conditioning system includes: obtaining dynamic environment monitoring data, including the detection values ​​of multiple temperature and humidity sensors in the target channel and the temperature and humidity in multiple air conditioners. The fan speed and water valve opening of the machine; according to multiple detection values ​​and preset state calculation data, calculate the corresponding state representation data, and then determine the predefined events corresponding to multiple temperature and humidity sensors; according to the predefined events, establish Obtain the corresponding event correlation matrix, and combine the preset weight coefficient matrix and the fan speed and water valve opening of multiple air-conditioning internal units to calculate the fan speed adjustment value and / or water valve opening corresponding to multiple air-conditioning internal units Adjust the value, and then control the fan target speed and / or the water valve target opening degree corresponding to multiple air-conditioning indoor units. This application controls the temperature of multiple air conditioners through distributed group control, which can greatly improve the temperature control effect of the data center computer room.

Description

technical field [0001] The present application relates to the technical field of air conditioning, and in particular, to a temperature control method and device for a multi-connected air conditioning system. Background technique [0002] The temperature control of the air conditioner is to control the supply air temperature or the indoor temperature (return air temperature) near the set target value. The PID feedback control method is a commonly used temperature control method for air conditioners. It controls the air supply temperature by adjusting the opening of the chilled water valve, and controls the indoor temperature by adjusting the fan speed of the variable frequency fan. It is mainly used to control a single air conditioner. Way. [0003] Currently, data centers, factories, and subway stations mostly use multi-split air conditioning systems. For the data center, the computer room of the data center has a large area, which requires multiple air conditioners to coo...
