Multi-stage high-efficiency evaporative cooling chiller

Abstract

The invention discloses a multi-stage efficient evaporative cooling water-chilling unit. The multi-stage efficient evaporative cooling water-chilling unit comprises a unit shell. A split packing type direct evaporative cooling unit is arranged in the center of the unit shell. A first packing-heat exchange tube combined evaporative cooling unit and a second packing-heat exchange tube combined evaporative cooling unit are arranged on the left side and the right side of the split packing type direct evaporative cooling unit correspondingly. An air inlet a is formed in the position, corresponding to the first packing-heat exchange tube combined evaporative cooling unit, of the side wall of the unit shell, and a high-temperature surface air cooler a is arranged between the first packing-heat exchange tube combined evaporative cooling unit and the air inlet a. An air inlet b is formed in the position, corresponding to the second packing-heat exchange tube combined evaporative cooling unit, of the side wall of the unit shell, and a high-temperature surface air cooler b is arranged between the second packing-heat exchange tube combined evaporative cooling unit and the air inlet b. Both the high-temperature surface air cooler a and the high-temperature surface air cooler b are connected with the split packing type direct evaporative cooling unit. The multi-stage efficient evaporative cooling water-chilling unit has the advantages that the height is small, the heat exchange efficiency of vertical tubes is high, the outlet water temperature is low, and the outlet water cleanliness is high.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to a multi-stage high-efficiency evaporative cooling chiller. Background technique [0002] In recent years, evaporative cooling chillers have been widely used in textile mills, office buildings, hotels, hospitals, shopping malls and other fields because they can produce cold water at a higher temperature and have a high energy efficiency ratio. [0003] At present, the more commonly used evaporative cooling chillers are two-stage evaporative cooling chillers. , the height of the unit is as high as 6m~7m, so in the strong wind season, it is easy to be affected by the pressure, resulting in an increase in the pressure bearing capacity of the unit, which will affect the firmness and sealing of the unit in the long run. In severe cases, the unit may be blown (2) The water temperature in the two-stage evaporative cooling chiller is greatly affected by cha...
