Performance Comparison And Thermodynamic Analysis Of Air Conditioning Dehumidification System

Air dehumidification systems for air conditioning are complex,diverse,and applicable to the environment.However,the performance of air conditioning dehumidification system mainly involves three parts: dehumidifier,heat exchanger and regenerator.Especially,the regenerator part can reduce energy consumption and efficient dehumidification,which plays an important role in the operation of air conditioning dehumidification system.Many experts and scholars have done a lot of research on these three factors,but they all focus on the selection and modification of dehumidifier,the structure of heat exchanger shape and the application of regenerator high temperature heat source,lack of thermodynamic mechanism in the process of explanation and the use of low temperature heat source.This paper attempts to make a comparison among many dehumidifiers.On this basis,the thermodynamic analysis of the regeneration process was carried out to clarify the meaning of regeneration thermodynamics.Finally,the regeneration process is optimized to improve the efficiency of the whole dehumidification system.First of all,by comparing the dehumidification performance of several kinds of equipment in terms of economy,complexity,energy storage,maintenance cost and occupation area,the advantages and disadvantages of various dehumidification equipment are clarified in the list,which provides theoretical guidance for the selection of dehumidification equipment in different dehumidification environments.Secondly,from the phase relationship,using thermodynamic analysis plays an important role in air conditioning dehumidification system of regeneration link,the concrete content is solid desiccant air regeneration and microwave regeneration as well as the liquid desiccant heating regeneration and heat transfer in the process of heating air regeneration mechanism of mass transfer to promote or inhibit each other,reveal the moisture content inverse migration and the thermodynamic principle of inverse heat transfer,deep profile control The thermodynamic mechanism involved in the regeneration process was analyzed to prepare for further optimization.Finally,FLUENT software was used to carry out numerical simulation on the liquid dehumidifier regenerator,and different inlet air volume and different inlet solution concentration temperature were simulated Through observing the temperature distribution in the regenerator,the paper provides engineering guidance for improving the regenerator’s regenerative efficiency,verifies the factors affecting the regenerator’s regenerative efficiency,and provides support for improving the regenerator’s efficiency.
