Open spiral winding type efficient cooling system

Abstract

The invention discloses an open spiral winding type efficient cooling system which comprises an open spiral winding type condenser, a cooling circulating pump, a sprayer, a water distributor, a fan, acooling packing layer and a cooling water tank. The open spiral wound condenser is soaked in cooling water of the cooling water tank, and the water distributor and the cooling circulating pump are arranged at the bottom of the interior of the cooling water tank; the sprayer is located above the cooling filler layer and sprays cooling water to the surface of the cooling filler layer; the cooling filler is arranged between the sprayer and the open spiral wound condenser, so that the contact area of the cooling water and air is increased, and the cooling water obtained after the cooling filler layer is cooled uniformly drops on the water surface of the cooling water tank; and the fan is arranged above the sprayer and is used for discharging vaporization latent heat of saturated water vapor obtained by vaporization in the cooling filler layer and the cooling water tank into outdoor atmosphere. The open spiral winding type efficient cooling system has the advantages of being small in size,compact in structure and modularized, and the purposes of saving electricity and water and facilitating online cleaning are achieved.

Description

technical field [0001] The invention relates to the field of air conditioning equipment, in particular to an open spiral winding high-efficiency cooling system. Background technique [0002] In the field of refrigeration and air conditioning, water-cooled air conditioners have higher cooling efficiency than air-cooled air conditioners, so they are the first choice for refrigeration equipment. Shell-and-tube condensers or sleeve-pipe condensers are widely used as standard accessories for water-cooled air conditioners due to their small heat transfer volume, high heat transfer efficiency, mature technology, and low cost. The cooling function is realized by means of cooling tower + shell-and-tube condenser (separated from the cooling tower). [0003] But there are two main problems in the existing cooling system: [0004] First, the existing water-cooled chillers share a set of cooling towers. When the refrigeration unit is operating at partial load, the cooling system is sti...

AI Technical Summary

Problems solved by technology

[0006] 1. Scale is not easy to clean: Since the heat exchange between the refrigerant and the brine (water) is completed in the closed shell tube, the scale in the shell tube must be cleaned after the shell tube condenser is disassembled under shutdown.

Causes high difficulty in maintenance, heavy workload, and frequent maintenance affects production

[0007] 2. The latent heat of vaporization decreases with the increase of pressure. The closed shell-and-tube heat exchanger or casing heat exchanger is not conducive to the vaporization and evaporation of cooling water, thus losing the latent heat of vaporization and reducing the cooling effect
