Preliminary dehumidification evaporative type air conditioner

Abstract

A pre-dehumidifying evaporative cooler comprises a housing (7), a wind inlet (1), and a wind outlet (2). A wind outlet fan (118) is disposed at the wind outlet (2). A dehumidifying refrigeration device is disposed at the wind inlet (1). A humidifying refrigeration device is disposed at the position at the inner side of the wind outlet fan (118). The dehumidifying refrigeration device dehumidifies new wind through spraying a LiCl solution, and lowers the temperature of the new wind through the heat transfer of a thermal pipe (126), thereby implementing dehumidification and temperature reduction. The humidifying refrigeration device performs secondary humidification and temperature reduction through water spraying. The pre-dehumidifying evaporative cooler adopts a structure that combines dehumidification and refrigeration and a two-level refrigeration structure, thereby eliminating the limitation effects on the evaporative cooler by high humidity, which has a desirable refrigeration effect even in high temperature, high humidity regions, and is especially applicable to refrigeration for telecommunications rooms, data rooms, and other dedicated rooms that require cooled air all around the year.

Description

technical field [0001] The invention relates to an evaporative air conditioner, in particular to a pre-dehumidification evaporative air conditioner. Background technique [0002] The current air conditioners are mainly divided into three categories: compressor type air conditioners, water evaporative air conditioners, and absorption type air conditioners. Compressor-type air conditioners are mainly composed of compressors, heat absorbers, radiators, various conduits and valves. There is a lot of electricity. Absorption air conditioners are mainly composed of regenerators, condensers, evaporators, absorbers, various pumps, conduits and valves. They have the advantage of large cooling power and can be driven by burning low-grade fuel or waste heat from waste gas and wastewater. , to save power resources, however, the manufacturing process of absorption air conditioners is very complicated, and it is difficult to manufacture and maintain. [0003] The evaporative air conditi...

Problems solved by technology

[0004] However, the traditional evaporative air conditioner also has a very serious shortcoming: its cooling efficiency is closely related to the humidity of the air. Low

However, in the humid southern region, the average relative humidity of the air is above 60%. When the air and water are in contact with the water-filled packing layer, the evaporation of water is limited, and the cooling efficiency of the evaporative air conditioner is greatly reduced. In humid areas and high humidity weather, traditional evaporative air conditioners lose their cooling effect
