Air conditioning system for data center machine room in high-humidity area and using method of air conditioning system

Abstract

The invention discloses an air conditioning system for a data center machine room in a high-humidity area and a using method of the air conditioning system. The system comprises a rotating wheel dehumidification evaporative cooling unit and an air conditioning air channel; the rotating wheel dehumidification evaporative cooling unit comprises a unit shell, a channel dividing section and a mixing section are arranged in the unit shell, a rotating wheel dehumidifier, a rotating wheel heat exchanger and a baffle are arranged in the channel dividing section, the channel dividing section is divided into a treated air duct and a regenerated air duct which are arranged up and down through the baffle, a coarse filter, a precooler and a recooler are sequentially arranged in the treated air duct in the air inlet direction, an electric heater and an exhaust fan are sequentially arranged in the regenerated air duct in the exhaust direction, and a direct evaporative cooler, a medium efficiency filter and an air supply fan are arranged in the mixing section; and the air conditioning air channel comprises a cold air channel and an air return channel. The system is reasonable in structural design, can be effectively applied to data center machine rooms in medium-humidity and high-humidity areas, and is remarkable in refrigeration effect and convenient to popularize.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning systems, and in particular relates to an air-conditioning system for a data center computer room in a high-humidity area and a method for using the same. Background technique [0002] The data center includes servers, communication equipment, refrigeration and power supply equipment, etc., and is the center of data processing. In order to ensure a reliable operating environment for the data center, the air conditioning system of the data center requires uninterrupted cooling throughout the year. Relevant data show that in 2017, the annual power consumption of China's data centers has exceeded 125 billion kW〃h, exceeding the combined annual power generation of the Three Gorges Dam and Gezhou Dam. At present, the energy consumption of air conditioning systems accounts for 40% of the total energy consumption of data centers. Compared with data centers in developed countries, the PUE of data...
