Integrated two-stage indirect evaporative cooling water chilling unit

Abstract

The invention discloses an integrated two-stage indirect evaporative cooling water chilling unit. The integrated two-stage indirect evaporative cooling water chilling unit comprises a horizontal pipeolive pipe type direct evaporative cooling unit and vertical pipe olive pipe type indirect evaporative cooling units which are symmetrically arranged on the left side and the right side of the horizontal pipe olive pipe type direct evaporative cooling unit, wherein two air inlets are symmetrically formed in the left side and the right side of the horizontal pipe olive pipe type direct evaporativecooling unit; and the two air inlets communicate with the vertical pipe olive pipe type indirect evaporative cooling units on the corresponding side. The integrated two-stage indirect evaporative cooling water chilling unit disclosed by the invention can shift between an evaporative cooling mode, an evaporative condensing mode and a natural cooling mode to operate according to climatic conditions,so that the integrated two-stage indirect evaporative cooling water chilling unit can perform cooling all the year around and is energy-saving and high-efficiency.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and relates to an integrated two-stage indirect evaporative cooling chiller. Background technique [0002] In recent years, data centers have higher and higher requirements for temperature and humidity, and with the expansion of the design temperature range of data centers, the temperature of water supply has increased. When traditional mechanical refrigeration chillers produce high-temperature cold water, compared with indirect evaporative cooling chillers Production of cold water consumes a lot of electricity, and the cost of operation and maintenance is high. If only indirect evaporative cooling chillers are used to produce cold water, it will be subject to meteorological conditions. In case of continuous rainy days, traditional mechanical refrigeration chillers still need to be turned on to produce high-temperature cold water . Contents of the invention [0003] The purp...
