Study On The Independent Humiture Control ＆ Liquid Desiccant Air-Condition And Argumentate On The Technique Scheme

Recently, building energy-efficient become more important than anytime before in our country, the independent humiture control & solution desiccant air-conditioning system as the new air-condition receives more and more people's value.In this system, whether provides massive inexpensive heats for the need of solution regeneration is the most important, and also decides whether this system obtains large-scale application. The article mainly proposes that the condenser heat recovery is used to for the solution regeneration, thus the new air-conditioning system which can save energy consumption can be achieved application.This article revolved the scheme of independent humiture control & solution desiccant air-conditioning system linking with condensation heat recovery technology, and mainly has done some research on the following aspects:①Introduced the the independent humiture control & solution desiccant air-conditioning systems in brief.②Analyzed the characteristics of desiccant solutions, and choosed LiCl solution as the desiccant solution in the; Used the heat and humidity exchange theory method to establishe correct mathematical model of desiccation and regeneration.③Analyzed the influence and tendency of the process of desiccation and regeneration; analysed the temperature, the concentration, and the flux of LiCl solution in solution desiccant system.④Taked an office building in Chongqing as the study object, and established the air-conditioning system scheme-No.1 primary scheme. Proposed betterment-scheme-A and betterment-scheme-B on the foundation of No.1 primary scheme. In the betterment-scheme-A, there has made three improvements on the foundation of No.1 primary scheme. In the betterment-scheme-B, the heat requirement in the process of regeneration can decrease 33.38% compared with that in No.1 primary scheme.⑤Proposed total chilled water equipment thermo-coefficient concept of the independent humiture control & solution desiccant air-conditioning systems. Proposed the scheme that using heat pump to provide heat need of solution regeneration-No.2 primary scheme. Proposed change scheme C and betterment scheme D. On the foundation of No.2 primary scheme, discussed the energy-efficient traits of change- scheme-C and betterment-scheme-D. ⑥Proposed the scheme that using condensation heat recovery of high temperature chilled water equipment to provide heat need of solution regeneration-No.3 primary scheme, and proposed total chilled water equipment thermo- coefficient concept of the systems of No.3-primary-scheme. On the foundation of No.3-primary- scheme, discussed the energy-efficient traits of betterment-scheme-E. And educed that systems total chilled water equipment thermo-coefficient of betterment-scheme-E increased 22.2 percent relative to No.3 primary scheme, and added 77.8 percent relative to the traditionall air-condition system.⑦Proposed the idea that the condensation heat recovery linking with solar energy light/heat transformation technology are applied in the solution desiccant system, and introduced betterment-scheme-F and betterment-scheme-G.Through the primary study in the paper, discovered that the scheme that using condensation heat recovery to provide heat need of solution regeneration have great energy saving potential and development value.
