Evaporation cooling ventilation air conditioner system for data center based on solar chimney

Abstract

The invention discloses an evaporation cooling ventilation air conditioner system for a data center based on a solar chimney. The system comprises an evaporation cooling unit arranged outside a data center machine room. The evaporation cooling unit is connected with the data center machine tool through a cold air conveying pipeline and an air return pipe, and the top of the data center machine room is further provided with an exhaust system. According to the evaporation cooling ventilation air conditioner system, since evaporation cooling has the characteristics of the large air amount, smallenthalpy difference, cooling and humidification, the way that a cold channel in the data center exhausts hot airflow out of the room is adopted, cold airflow and hot airflow can be completely isolated, and meanwhile humidity accumulation in the machine room can be avoided; in addition, the solar chimney is arranged, hot airflow in a hot channel can be directly exhausted out of the room through thesolar chimney, an exhaust fan is omitted, and the indoor airflow distribution mode is optimized; and the two factors are combined, renewable energy sources such as solar energy and outdoor environment dry air energy are sufficiently utilized, and energy consumption of a refrigeration system of the data center can be reduced to the minimum.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to an evaporative cooling ventilation and air-conditioning system for a data center based on a solar chimney. Background technique [0002] In the Internet era, we have witnessed the prosperity of modern data center construction. At the same time, the power of IT equipment in servers is also increasing day by day, and the heat density is increasing rapidly. How to ensure the normal operation of data processing equipment without consuming large cooling energy consumption has become an issue of increasing concern for data center cooling systems. [0003] Traditional data center air conditioners are prone to severe mixing of cold and heat due to their low supply air temperature, and their airflow organization is also very chaotic, resulting in poor cooling effect and high energy consumption. Contents of the invention [0004] The purpose of the present...
