Evaporation cool evaporation water amount control device and control method

Abstract

The invention discloses an evaporation cool evaporation water amount control device and control method. The control device includes a water storage box, a spray water pump, a pipeline, a heat insulation chamber and a nozzle. The heat insulation chamber is provided with an air inlet and an air outlet. The two ends of the pipeline are both located in the water storage box. The spray water pump is arranged in the pipeline. The nozzle is arranged in the pipeline located in the heat insulation chamber. The pipeline is connected with a water pressure sensor and a regulating valve. The heat insulation chamber is internally provided with a temperature and humidity sensor. The control method is that according to the water pressure in the pipeline and the humidity in the heat insulation chamber, theopening of the regulating valve is controlled, so that the purpose of controlling the spray water amount from the nozzle is achieved. By means of the evaporation cool evaporation water amount controldevice and control method, increasing of the contact area between water and air is achieved by the size and amount of water spray particles, water droplets are prompted to be better integrated with air, the evaporation water amount is effectively controlled, and meanwhile, the water evaporation effect is further improved, and evaporation cooling efficiency is improved.

Description

Technical field [0001] The invention belongs to the technical field of air conditioners, and particularly relates to an evaporative cold evaporating water volume control device and a control method thereof. Background technique [0002] The total number of data centers in my country exceeds 400,000, and the overall PUE of the data center computer room remains high, and the power consumption has exceeded 1.5% of the total power of the whole society. In order to reduce the energy consumption of the data center, the relevant departments of computer room construction jointly formulated the "National Green Data Center Pilot Work Plan." It is required to create one hundred green data centers in key areas in 2017. The requirements for green data centers are: 1) Full use of natural cold sources; 2) Recycling of water resources; 3) Low PUE. Evaporative cooling is a pure natural cooling source cooling method that meets the requirements of a green data center and has attracted the attentio...
