Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] The present invention is an evaporative cooling chiller for solution dehumidification and moisture permeable membrane dehumidification, such as figure 1 As shown, including interconnected cold water production unit and dehumidification solution regeneration unit;

[0033] The cold water production unit includes a unit casing 16. A direct evaporative cooling section is arranged inside the unit casing 16. A unit air outlet 13 is arranged on the top of the direct evaporative cooling section. The internal structures of the unit casing 16 on both sides of the direct evaporative cooling section are symmetrical and identical. , specifically including the unit air inlet 1 located on the side wall of the unit housing 16, the unit air inlet 1 is provided with a filter 2, a surface cooler 3, a plate tube indirect evaporative cooling unit, a dehum...

Abstract

The invention discloses an evaporative cooling water chilling unit achieving dehumidifying through a solution dehumidifying humidity-permeable film. The evaporative cooling water chilling unit comprises a cold water production unit and a dehumidifying solution regeneration unit which are mutually connected; and the cold water production unit comprises a unit shell, a direct evaporative cooling section is arranged in the unit shell, the internal structures of the portions, on the two sides of the direct evaporative cooling section, of the unit shell are symmetrical and same and each comprise aunit air inlet, and filters, surface coolers, plate tube indirect evaporative cooling units, dehumidifying sections and the direct evaporative cooling section are sequentially arranged in the unit airinlets in the air flowing direction. According to the evaporative cooling water chilling unit, outdoor fresh air is precooled and subjected to dehumidifying treatment through dry air energy and a solution dehumidifying technology based on the film, air and a dehumidifying solution can be isolated from a polymer film with the high permselectivity through solution dehumidifying humidity-permeable film packing, the dehumidifying solution does not directly make contact with the air, water molecules are only allowed to be transmitted through permeation under driving of partial pressure differenceof water steam, and passing of germs and the dehumidifying solution is isolated.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to an evaporative cooling water chiller for solution dehumidification and moisture-permeable film dehumidification. Background technique [0002] Evaporative cooling technology has been widely used due to its advantages of environmental protection, water saving and energy saving. It relies on the latent heat of vaporization when the cooling medium evaporates to remove heat to achieve the purpose of reducing the temperature of the unit's own circulating water and provide high-temperature cold water for users or air-conditioning terminals. [0003] For areas with high temperature and high humidity, outdoor air is generally directly used to enter the evaporative cooling chiller for heat exchange. This kind of device is inefficient and cannot meet the requirements of the outlet water temperature. Contents of the invention [0004] The purpose of the pres...
