【摘要】：太陽(yáng)能溶液除濕空調(diào)系統(tǒng)是一種極具發(fā)展前景的空調(diào)系統(tǒng)，可利用低品位熱源實(shí)現(xiàn)溶液再生，耗電小和對(duì)環(huán)境無(wú)污染。集熱型再生器把再生器和太陽(yáng)能集熱器集中在一起，，再生器作為太陽(yáng)能溶液除濕空調(diào)系統(tǒng)的核心部件之一，它的效率、運(yùn)行狀況、結(jié)構(gòu)和初投資等直接影響系統(tǒng)的性能及可行性。因此，人們希望設(shè)計(jì)出一種可靠、和性價(jià)比高的集熱型再生器。多年來(lái)，國(guó)內(nèi)外許多學(xué)者對(duì)其進(jìn)行了大量的理論分析計(jì)算和實(shí)驗(yàn)研究。 本文主要對(duì)翅化板式集熱型再生器和平板式集熱型再生器的再生性能進(jìn)行了理論分析和實(shí)驗(yàn)研究，設(shè)計(jì)和搭建了具體的再生器實(shí)驗(yàn)臺(tái)，建立了理論計(jì)算模型，選擇了LiCl溶液作為再生溶液，分析了在廣州地區(qū)室外天氣下，空氣和溶液進(jìn)口溫度、空氣含濕量、空氣和溶液進(jìn)口流量、溶液濃度以及太陽(yáng)能輻射強(qiáng)度七個(gè)參數(shù)對(duì)這兩種再生器的溶液再生量和再生器效率的影響，同時(shí)比較了兩種再生器的溶液再生量和再生器效率。 實(shí)驗(yàn)和理論分析結(jié)果表明：在相同的實(shí)驗(yàn)工況下和再生器其它結(jié)構(gòu)參數(shù)不變的情況下，翅化板式集熱型再生器的溶液再生量和再生器效率均高于平板式集熱型再生器，采用翅化板式集熱型再生器代替平板式集熱型再生器，能夠提高再生器的集熱性能，翅化板式集熱型再生器的溶液再生量比平板式集熱型再生器的溶液再生量多140g/h左右，溶液的再生量能夠提高13%~22%左右，再生器效率能夠提高7%左右。且這兩種再生器的溶液再生量和再生器效率都有著相同的再生規(guī)律，即：溶液再生量和再生器效率隨著空氣進(jìn)口流量和進(jìn)口溫度、溶液進(jìn)口流量和進(jìn)口溫度的增加而增加，隨著溶液進(jìn)口濃度和空氣進(jìn)口含濕量的增加而減小；溶液再生量隨著太陽(yáng)能輻射強(qiáng)度的增加而增加，再生器效率隨著太陽(yáng)能輻射強(qiáng)度的增加而減小。
[Abstract]:Solar solution dehumidification air conditioning system is a kind of air conditioning system with great development prospect. It can use low grade heat source to realize solution regeneration, with little electricity consumption and no pollution to the environment. The collector brings together the regenerator and the solar collector. As one of the core components of the solar solution desiccant air conditioning system, the regenerator is efficient and operating. Structure and initial investment directly affect the performance and feasibility of the system. Therefore, people hope to design a reliable, and high cost-effective heat collector. Over the years, many scholars at home and abroad have done a lot of theoretical analysis and calculation and experimental research. In this paper, the theoretical analysis and experimental study on the regeneration performance of the wing plate type regenerator and the plate type regenerator are carried out, the concrete regenerator experimental bench is designed and built, and the theoretical calculation model is established. The LiCl solution was selected as the regenerated solution. The inlet temperature of air and solution, the moisture content of air and the flow rate of inlet air and solution were analyzed in the outdoor weather of Guangzhou area. The effects of solution concentration and solar radiation intensity on the solution regeneration quantity and regeneration efficiency of the two regenerators were studied. The solution regeneration capacity and the regenerator efficiency of the two regenerators were also compared. The results of experiment and theoretical analysis show that under the same experimental conditions and the same structural parameters of regenerator, the regenerator's solution regeneration capacity and regenerator efficiency are higher than those of flat plate type regenerator. The performance of the regenerator can be improved by using the wing plate type collector instead of the flat plate type regenerator. The amount of solution regeneration of the wing plate type regenerator is more than that of the flat plate type regenerator about 140g/h. The regeneration capacity of the solution can be increased by about 13 ~ 22%, and the efficiency of the regenerator can be increased by about 7%. Both of the two kinds of regenerators have the same regeneration law, that is, the amount of solution regeneration and the efficiency of regenerator increase with the increase of air inlet flow rate and inlet temperature, solution inlet flow rate and inlet temperature. With the increase of the inlet concentration of the solution and the moisture content of the air inlet, it decreases. The amount of solution regeneration increases with the increase of solar radiation intensity, and the efficiency of regenerator decreases with the increase of solar radiation intensity.
