Evaporative cooling system and control method

Abstract

The embodiment of the invention provides an evaporative cooling system and a control method. The evaporative cooling system comprises evaporative cooling units, a mechanical refrigerating unit, a heatexchanger, a return air duct, a fresh air duct, an exhaust duct and an air supply duct. The evaporative cooling units comprise the direct evaporative cooling unit and the indirect evaporative coolingunit. The evaporative cooling units are used for making high-temperature gas delivered from the return air duct in direct or indirect contact with low-temperature water of the evaporative cooling units to conduct heat exchange and then delivering the high-temperature gas into the air supply duct. The heat exchanger is used for enabling the high-temperature gas delivered from the return air duct to conduct heat exchange with low-temperature gas in the exhaust duct and the fresh air duct and then delivering the high-temperature gas into the evaporative cooling units. The evaporative cooling system achieves free refrigerating through outdoor cold air to prevent a compressor from being started all the year. The situation that a single evaporative cooling tower system can hardly adapt to extreme weather is also avoided. The effects of energy-saving cooling, high-efficiency heat exchange, accurate control and safe and reliable operation of a container data center are achieved.

Description

technical field [0001] The invention relates to the technical field of data center cooling, in particular to an evaporative cooling system and a control method. Background technique [0002] With the development of information technology, the heat dissipation of servers and the heat dissipation density of computer rooms increase, and the precision air-conditioning heat dissipation method relying on electricity will gradually be replaced by new cooling methods. Evaporative cooling technology is a technology that uses dry air to produce cold air. It can provide cold air according to the needs of the end to cool the data center. Evaporative cooling air-conditioning technology is an environmentally friendly, efficient and economical cooling method that uses the difference between the dry bulb temperature and the dew point temperature of the dry air in the natural environment to obtain cooling capacity through the heat and moisture exchange between water and air. Low cost of coo...

AI Technical Summary

Problems solved by technology

Existing data centers use evaporative cooling air conditioners for cooling, but there are still technical defects such as low heat exchange efficiency and high energy consumption

[0003] Therefore, there is an urgent need for a dual cooling source data center and a temperature control method to solve the problems of low heat dissipation and high energy consumption at the air-cooled end of the existing data center
