Evaporative cooling-condensation modular air conditioning unit for data center computer room

Abstract

The invention discloses an evaporative cooling-condensation modular air conditioning unit for a data center computer room, which comprises a unit shell. The unit shell is internally provided with a mechanical refrigeration unit; one side of the mechanical refrigeration unit is provided with a return air unit, an early effect filter, a tubular indirect evaporative cooling unit, an evaporator, a direct evaporative cooling unit and an air supply unit sequentially; and the mechanical refrigeration unit and the evaporator are connected through a pipeline to form a closed loop. According to the evaporative cooling-condensation modular air conditioning unit for the data center computer room disclosed in the invention, evaporative cooling and mechanical refrigeration are combined, the stable operation performance of the unit is increased while the energy efficiency of the unit is improved, and continuous indoor cooling in summer is realized.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and relates to an evaporative cooling-condensing modular air-conditioning unit for a data center computer room. Background technique [0002] With the development of economic construction, a large number of commercial, civil and industrial buildings have been built. However, the air-conditioning equipment and systems used in domestic buildings currently have the problem of high energy consumption. Under the call of the national energy conservation and emission reduction policy, we need a new type of air conditioner with low energy consumption or even zero energy consumption to meet people's more requirements for working and living environments. [0003] The traditional mechanical refrigeration air conditioner not only has high initial investment but also consumes a lot of energy for system operation. In extreme weather in summer, the outdoor air temperature is too high, which w...

AI Technical Summary

Problems solved by technology

[0003] The traditional mechanical refrigeration air conditioner not only has high initial investment but also consumes a lot of energy in system operation. In extreme weather in summer, the outdoor air temperature is too high, which will lead to poor heat dissipation of the condenser, which will cause the compressor to turn on the overheating protection and stop cooling the room.

[0004] Evaporative cooling air-conditioning technology uses water as the cooling medium, cools and dissipates heat through water evaporation and absorbs heat, and uses "dry air energy" to produce cold air or cold water through direct or indirect contact between air and water. This technology has been used in Northwest China And the southeast coastal areas are widely used, but in fact, due to the influence of outdoor meteorological conditions (the influence of dry and wet bulb temperature difference), the cooling performance of the unit is unstable
