Abstract

The invention discloses an evaporative cooling independent temperature and humidity control fresh air handling unit used for a dry region. The fresh air handling unit comprises a unit shell, an air inlet is formed in one side wall of the unit shell, and a filtering device and an evaporative cooling independent temperature and humidity control unit are sequentially arranged in the unit shell in the air flow direction after air enters the unit shell. By means of the evaporative cooling independent temperature and humidity control fresh air handling unit used for the dry region, the problems that a solution dehumidification fresh air handling unit is large in investment, high in corrosivity and unadapted to the northwest dry region in China are solved.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to a fresh air unit for independent control of temperature and humidity by evaporative cooling in a dry area. Background technique [0002] The temperature and humidity independent control air conditioning system is mainly composed of fresh air units and chillers. When this system is applied in the humid southeast of my country, the internal fresh air units are mainly solution dehumidification fresh air units. Although the solution dehumidification fresh air unit can meet the temperature and humidity requirements, but because the lithium bromide solution is used in the unit, it is highly corrosive, which reduces the service life of the unit to a certain extent, and its thermal efficiency is low, which requires a lot of sealing of the equipment. High, and the price of lithium bromide solution is relatively expensive. [0003] For the dry area in Northw...
