Problems solved by technology

The calorific value of a single cabinet in the data center reaches 15kW or even higher. It is difficult to solve the heat dissipation problem of this kind of high heat density computer room by using the traditional direct expansion computer room air conditioner or chilled water computer room air conditioner, and it is easy to generate hot spots locally
[0003] At the same time, because the greater the heat of the cabinet, the greater the air volume will be. The traditional computer room air conditioner will use a larger air supply system; due to the larger air supply distance, the pressure head loss of the air supply is also greater. Therefore, the power consumption of the fan is greatly increased, which also brings an additional heat load. In some cases, the power consumption of the fan reaches 10% of the heat load of the computer room.

Abstract

The invention discloses a novel backboard air conditioning system, which comprises at least two heat exchange devices, wherein each heat exchange device is connected with at least two backboard air conditioners; each backboard air conditioner is arranged on a rear door of one cabinet in a machine room; each backboard air conditioner comprises two paths of heat exchange coils; and the two paths of heat exchange coils of the same backboard air conditioner are connected with two different heat exchange devices. Compared with the prior art, the system provided by the invention is improved in unit operation safety and reliability as both an external cold source part and a backboard air conditioning heat exchange part of the system have dual backup. Each backboard air conditioner is arranged on the rear door of one cabinet in the system; and the air supply distance is short, so that the problems of cold air and hot air mixing and a short circuit are solved; the heat exchange efficiency of the system is improved; the power consumption of the unit is reduced; and the problem of high heat density of the machine room is solved.

Description

technical field [0001] The invention relates to an air-conditioning system, in particular to an energy-saving air-conditioning system applied to a data center. Background technique [0002] In recent years, with the development of informatization, the integration of communication equipment has become higher and higher, the power of a single rack in the computer room has been continuously increased, and the emergence of high-density and high-heat computer rooms has brought about the overall planning of our computer room, especially the solution of the air conditioning system. a big challenge. The calorific value of a single cabinet in a data center reaches 15kW or even higher. It is difficult to solve the heat dissipation problem of such a high-heat-density computer room by using traditional direct-expansion computer room air conditioners or chilled water computer room air conditioners, and it is easy to generate hot spots locally. [0003] At the same time, because the grea...
