Photovoltaic direct drive dew point indirect evaporative cooling air conditioning system for data centers

Abstract

The invention discloses a photovoltaic direct drive dew point indirect evaporative cooling air conditioning system for a data center. The photovoltaic direct drive dew point indirect evaporative cooling air conditioning system comprises a dew point indirect evaporative cooling air conditioning unit, a data computer room and a direct drive system for photovoltaic power generation, wherein the dew point indirect evaporative cooling air conditioning unit communicates with the data computer room through a return duct and a blast pipe and forms a closed loop; and the direct drive system for photovoltaic power generation is arranged at the top of the dew point indirect evaporative cooling air conditioning unit, and the dew point indirect evaporative cooling air conditioning unit is connected with the direct drive system for photovoltaic power generation. The air conditioning system disclosed by the invention solves the problems of excessive energy consumption and high PUE of a conventional mechanical refrigeration air conditioning system, and easy formation of local hot spots in a cabinet when the cabinet is sealed by using a cold passage.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to a photovoltaic direct-drive dew point indirect evaporative cooling air-conditioning system for a data center. Background technique [0002] At present, the data center has maintained a rapid development trend in the area of ​​new data center computer rooms. However, there are still some problems in terms of energy consumption and PUE, such as excessive energy consumption and high PUE, which will hinder the sustainable development of the data center construction industry. Under the guidance and support of a series of relevant policies, the use of natural cooling sources to cool down computer rooms has become a future development trend. [0003] Indirect evaporative cooling technology is currently widely used in data centers. The cooling demand of data centers is met by indirect cooling of the return air in the computer room. However, due to the cons...
