【摘要】：本文建立了一級(jí)固體干燥劑轉(zhuǎn)輪除濕空調(diào)系統(tǒng)，模擬了夏季不同干濕氣候條件下固體干燥劑轉(zhuǎn)輪除濕空調(diào)系統(tǒng)的除濕過(guò)程。通過(guò)傳熱傳質(zhì)分析，建立了除濕轉(zhuǎn)輪的數(shù)學(xué)模型。以轉(zhuǎn)輪微通道為研究對(duì)象，用COMSOL多物理場(chǎng)耦合軟件對(duì)除濕轉(zhuǎn)輪進(jìn)行模擬研究，分析了再生風(fēng)入口溫濕度、處理風(fēng)入口溫濕度對(duì)系統(tǒng)送風(fēng)含濕量和送風(fēng)溫度的影響。 在特定的干濕氣候條件下，對(duì)固體干燥劑轉(zhuǎn)輪除濕空調(diào)系統(tǒng)進(jìn)行了正交試驗(yàn)研究。根據(jù)實(shí)驗(yàn)指標(biāo)及正交實(shí)驗(yàn)原理選定正交表，確定了系統(tǒng)的實(shí)驗(yàn)方案，根據(jù)設(shè)備運(yùn)行特點(diǎn)和實(shí)驗(yàn)需求確定了實(shí)驗(yàn)數(shù)據(jù)的測(cè)試方案，包括轉(zhuǎn)輪除濕空調(diào)箱的溫度和含濕量的測(cè)量，以及處理過(guò)程和再生過(guò)程風(fēng)量的測(cè)定。 對(duì)系統(tǒng)實(shí)驗(yàn)數(shù)據(jù)進(jìn)行了深入的分析，研究影響轉(zhuǎn)輪除濕性能的7個(gè)因素對(duì)處理空氣出口溫度和含濕量的影響，，并求出評(píng)價(jià)指標(biāo)轉(zhuǎn)輪除濕性能系數(shù)和除濕量。利用極差分析和方差分析的方法，計(jì)算出7個(gè)因素對(duì)除濕轉(zhuǎn)輪出口狀態(tài)參數(shù)影響的權(quán)重，以及7個(gè)參數(shù)在特定干濕氣候區(qū)條件下的最優(yōu)組合。得出試驗(yàn)中影響轉(zhuǎn)輪除濕性能的顯著因素和顯著性水平，通過(guò)與實(shí)驗(yàn)結(jié)果的比較證明理論模擬的正確性。最后，通過(guò)比較得出結(jié)論： （1）濕潤(rùn)地區(qū)、半濕潤(rùn)和半干旱地區(qū)，影響除濕性能系數(shù)和除濕量的最顯著因素均為再生風(fēng)量，而干旱地區(qū)中影響除濕性能系數(shù)和除濕量的最顯著性因素均為處理空氣入口相對(duì)濕度。 （2）在各干濕氣候區(qū)中，隨處理風(fēng)量和再生風(fēng)入口相對(duì)濕度的增加，除濕性能系數(shù)和除濕量都減小；隨再生風(fēng)量和處理空氣入口溫度的增加，除濕性能系數(shù)和除濕量均增大；隨處理空氣入口相對(duì)濕度增大，除濕量增大，在半干旱地區(qū)的除濕性能系數(shù)減小，其余地區(qū)表現(xiàn)為增大；再生空氣入口溫度增大，各地區(qū)的除濕性能系數(shù)都有下降，而除濕量的變化趨勢(shì)是斜率幾乎為零的線性增加；隨著轉(zhuǎn)輪轉(zhuǎn)速的增大，各地區(qū)的除濕性能系數(shù)變化表現(xiàn)為稍微下降，而濕潤(rùn)和半濕潤(rùn)地區(qū)的除濕量基本不變且基本相同，半干旱和干旱地區(qū)除濕量明顯增加。
[Abstract]:A desiccant rotary desiccant air conditioning system is established in this paper. The desiccant air conditioning system is simulated under different dry and wet weather conditions in summer. The mathematical model of desiccant runner is established by analyzing heat and mass transfer. The desiccant runner was simulated with COMSOL multi-physical coupling software. The influence of inlet temperature and humidity of regenerative air on the moisture content and air temperature of the system was analyzed. The orthogonal experimental study on the desiccant rotary dehumidification air conditioning system was carried out under the specific dry and wet climate conditions. The orthogonal table is selected according to the experimental index and the principle of orthogonal experiment, the experimental scheme of the system is determined, and the test scheme of the experimental data is determined according to the operating characteristics and experimental requirements of the equipment, including the measurement of the temperature and moisture content of the rotary dehumidification air conditioning box. And the determination of air volume in the process of treatment and regeneration. The experimental data of the system are analyzed in depth. The influence of seven factors affecting the dehumidification performance of the runner on the air outlet temperature and moisture content are studied, and the evaluation index, the dehumidification coefficient and the dehumidification quantity of the runner are obtained. By means of range analysis and variance analysis, the weight of seven factors on the outlet parameters of dehumidified runner and the optimal combination of 7 parameters in a given dry and wet climate zone are calculated. The remarkable factors and significance level of the dehumidification performance of the runner are obtained, and the correctness of the theoretical simulation is proved by comparing the experimental results with the experimental results. Finally, the conclusion is drawn by comparison: 1) in humid areas, semi-humid and semi-arid areas, the most significant factors affecting the dehumidification performance coefficient and dehumidification amount are regenerated air volume. The most significant factors affecting the dehumidification performance coefficient and the dehumidification amount in arid areas were the air inlet relative humidity. (2) in each dry-wet climate region, the dehumidification performance coefficient and the dehumidification amount decrease with the increase of the treatment air volume and the inlet relative humidity of the regenerated air, and the dehumidification performance coefficient and the dehumidification amount increase with the increase of the regenerated air volume and the inlet temperature of the treated air. With the increase of air inlet relative humidity, the dehumidification coefficient decreases in semi-arid area and increases in other regions, and the dehumidification coefficient decreases with the increase of inlet temperature of regenerated air. The trend of dehumidification is a linear increase with a slope of almost zero. With the increase of rotary speed, the dehumidification performance coefficient of each region decreases slightly, while the dehumidification rate in humid and sub-humid areas is basically the same. The amount of dehumidification in semiarid and arid areas increased markedly.
