Method, device and system for controlling refrigeration of computer room

Abstract

The invention relates to the technical field of refrigeration devices and discloses a method, device and system for controlling refrigeration of a computer room. The system for controlling refrigeration comprises a cooling tower which is located outdoors and comprises a fan arranged on the top of the cooling tower, a first surface air cooler, a first water pump, a second surface air cooler, an air feeder, a temperature sensor and a control device, wherein the first surface air cooler, the first water pump and the second surface air cooler are connected in sequence through a first pipeline, so that closed circulation is formed, the first surface air cooler is located in the cooling tower, the second surface air cooler is located on side of a return air inlet of the computer room and used for cooling return air of the computer room, water in the first surface air cooler is pumped into the second surface air cooler through the first water pump, the air feeder is located on one side of an air supply opening of the computer room and used for conveying cooled return air of the computer room to the computer room, the temperature sensor is located outdoors and used for detecting outdoor temperature information, the control device is connected with the temperature sensor and the first water pump through signals and used for controlling the first water pump to be started when the outdoor temperature is lower than a set first temperature threshold. The system for controlling refrigeration is beneficial to the improvement of the quality of air in the computer room and reduces energy consumption.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration control method, device and system for a machine room. Background technique [0002] A data center, commonly known as a computer room, is a complete set of complex facilities. It includes not only computer systems and other supporting equipment (such as communication and storage systems), but also redundant data communication connections, environmental control equipment, monitoring equipment, and various safety devices. In existing data centers, energy costs account for a relatively high proportion of computer room operating costs, and less than half of the electricity is used for IT loads, while the rest is used for infrastructure such as power supply and cooling systems. [0003] Using outdoor fresh air to cool naturally is an energy-saving operation mode for equipment rooms. Currently, cooling systems using outdoor fresh air are figure 1 As sho...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the existing technology is that in winter, outdoor fresh air is used for direct cooling, which is not very significant in terms of energy saving, and requires a large amount of humidification, which also easily affects the air quality in the computer room
