Novel air conditioning system in machine room based on underfloor air distribution and air distribution method thereof

Abstract

The invention relates to a novel air conditioning system in a machine room based on underfloor air distribution and an air distribution method thereof. A cold / hot water output end of an air source cold / hot water unit is connected with the input end of a water pump. The input end of the water pump is connected with the input end of an electrically operated valve. The output end of the electrically operated valve is connected with the first input end of an air handling unit, and the first output end of the air handling unit is connected with the input end of the air source cold / hot water unit. The second output end of the air handling unit is connected with the air input end of the room through a first pipeline. The air output end of the room is connected with the second input end of the air handling unit through a second pipeline. The third input end of the air handling unit is communicated with atmosphere. An inner air distribution cabinet is placed on an elevated floor. An air distribution opening of an air distribution channel of the inner air distribution cabinet is connected with an air distribution opening of the elevated floor. According to the system, air is directly distributed to nearby computers in layers of the air distribution cabinet, so that high air distribution temperature is allowed, thereby further improving the water supply temperature of the air source cold / hot water unit, improving the energy efficiency ratio and saving the energy source.

Description

technical field [0001] The invention relates to a novel machine room air-conditioning system based on floor air supply and an air supply method thereof, belonging to the technical field of refrigeration and air-conditioning system design and manufacture. Background technique [0002] With the rapid development of computer technology and information network, almost all large enterprises and institutions have their own computer rooms for placing various servers, routers and other equipment, and they are in long-term uninterrupted operation. In this way, higher requirements are put forward for the temperature and humidity of the computer room, the layout of cables and communication lines. [0003] The floor air supply air conditioning system uses the space between the elevated floor and the floor as the air supply static plenum, and the ample space of the static plenum can be used as the channel for cables and communication lines. Moreover, the floor air supply system has the ...

Problems solved by technology

In this process, due to the temperature stratification of the room, the temperature in the upper space of the cabinet is higher and the temperature in the lower space is lower, resulting in different cooling effects on each layer of the cabinet.

At the same time, because only part of the cold air enters the cabinet to cool the computer equipment, most of the supply air is mixed with the exhaust air of the cabinet and then discharged out of the room. The supply air is not fully utilized to cool the cabinet, and the operating efficiency is greatly reduced.
