Air-handling system for high sensible heat and low latent heat load region

Abstract

The invention relates to an air treatment system for areas with high sensible heat and low latent heat load, which comprises an air treatment device (1) and an air conditioning chamber (5), wherein an air inlet (11) of the air treatment device (1) is communicated with external air through a fresh air pipe (2). The system is characterized in that the top of the air conditioning chamber (5) is provided with one or a plurality of air supply ports (3) and air return ports (4); the air supply ports (3) and the air return ports (4) are communicated with an air outlet end (12) of an air pipe and an air return end (13) of the air treatment device (1) respectively; a high sensible-heat air conditioning area of the air conditioning chamber (5) is provided with one or more than two humidifiers (6); and equal-enthalpy humidification is performed to the air conditioning chamber (5) through the humidifiers (6). The system has the advantages that the system changes the heat-humidity ratio characteristic of air conditioning load, effectively utilizes the heat-humidity treatment capability of a surface cooler in the air treatment device, increases the enthalpy difference of air treatment, improves the heat exchange efficiency of coils so as to effectively reduce the air quantity of air treatment, and achieves the effects of saving investment and the operation energy consumption of air conditioners, reducing noise and improving the comfort property of the air conditioners.

Description

technical field [0001] The invention relates to an air treatment system, in particular to an air treatment system used in areas with high sensible heat and low latent heat load; it is a method for increasing the enthalpy difference of air treatment with high sensible heat load by using isenthalpic humidification. It belongs to the technical field of air conditioning. Background technique [0002] At present, when the existing air handler is applied to an air-conditioned room with high sensible heat and low latent heat load, the latent heat treatment capacity of the cooling coil of the air handler is not well utilized. In order to meet the temperature requirements of air-conditioning areas with high sensible heat and low latent heat load, ordinary air handling systems have the following disadvantages: the enthalpy difference of treatment is small, resulting in large air volume for air handling, high energy consumption for fan transmission, high noise, and large investment in ...
