【摘要】：隨著人們對(duì)于生活品質(zhì)的追求,對(duì)能源的需求量也越來(lái)越大。為了減緩能源的消耗,提高室內(nèi)空氣品質(zhì),降低固體除濕轉(zhuǎn)輪的再生能耗,本文提出了固體除濕轉(zhuǎn)輪與空氣源熱泵結(jié)合的溫濕度獨(dú)立控制的空調(diào)系統(tǒng)。通過(guò)MATLAB編程求解除濕轉(zhuǎn)輪的數(shù)學(xué)模型,得出了不同因素對(duì)轉(zhuǎn)輪性能的影響,并通過(guò)實(shí)驗(yàn)對(duì)模擬結(jié)果進(jìn)行了驗(yàn)證。根據(jù)除濕轉(zhuǎn)輪的研究結(jié)果并結(jié)合前人對(duì)溶液除濕的研究,利用熱泵機(jī)組作為冷熱源,通過(guò)理論計(jì)算對(duì)比分析了冷凝除濕、轉(zhuǎn)輪除濕與溶液除濕在室內(nèi)只有濕負(fù)荷時(shí)的能耗與(火用)效率。針對(duì)除濕轉(zhuǎn)輪能耗過(guò)高,提出了除濕轉(zhuǎn)輪與空氣源熱泵結(jié)合的空調(diào)系統(tǒng),利用熱泵壓縮機(jī)的高溫排氣與冷凝熱再生除濕轉(zhuǎn)輪以減小能耗,除濕轉(zhuǎn)輪承擔(dān)室內(nèi)濕負(fù)荷,熱泵機(jī)組制取高溫冷水/低溫?zé)崴ㄟ^(guò)輻射板向室內(nèi)供冷/熱。對(duì)除濕轉(zhuǎn)輪與空氣源熱泵結(jié)合的空調(diào)系統(tǒng)的主要部件進(jìn)行了設(shè)計(jì)計(jì)算,并在焓差實(shí)驗(yàn)室搭建了實(shí)驗(yàn)臺(tái)進(jìn)行實(shí)驗(yàn)研究。除濕轉(zhuǎn)輪的研究結(jié)果表明:模擬結(jié)果與實(shí)驗(yàn)結(jié)果基本吻合,證明模擬程序正確可用;增大再生空氣溫度、降低再生空氣含濕量、降低處理空氣進(jìn)口溫度能使轉(zhuǎn)輪除濕量增加,減小處理空氣進(jìn)口含濕量、減小再生風(fēng)速與處理風(fēng)速使轉(zhuǎn)輪除濕量減小;不同的運(yùn)行工況,對(duì)應(yīng)有不同最優(yōu)轉(zhuǎn)速和最優(yōu)再生面積與除濕面積比。對(duì)冷凝除濕、轉(zhuǎn)輪除濕與溶液除濕的能耗計(jì)算表明,在設(shè)計(jì)工況下,冷凝除濕耗功最小、(火用)效率最高,而轉(zhuǎn)輪除濕的耗功最大、(火用)效率最低;室內(nèi)含濕量較小時(shí),冷凝除濕性能明顯降低。以鎮(zhèn)江地區(qū)一套民居的負(fù)荷特點(diǎn)為研究對(duì)象,通過(guò)實(shí)際運(yùn)行除濕轉(zhuǎn)輪與空氣源熱泵結(jié)合的空調(diào)系統(tǒng),得出在設(shè)計(jì)工況下系統(tǒng)制冷量能夠達(dá)到14.76kW,除濕量8.1g/kg,能夠滿足室內(nèi)熱濕負(fù)荷的要求。夏季工況時(shí),系統(tǒng)整體COP可達(dá)到4.1,比傳統(tǒng)空調(diào)系統(tǒng)節(jié)能13.6%;冬季供熱工況時(shí)系統(tǒng)COP為3.68,比傳統(tǒng)空調(diào)系統(tǒng)節(jié)能20%。
[Abstract]:Along with the people for the pursuit of quality of life, the demand for energy is also growing. In order to reduce energy consumption, improve indoor air quality, reduce the energy consumption of solid desiccant regeneration, this paper puts forward the independent temperature and humidity air conditioning system with solid desiccant and air source heat pump control. The mathematical model of MATLAB programming solution dehumidification the runner, the influence of different factors on the performance of the runner and through the experiment, the simulation results were verified. According to the research results of desiccant wheel and the combination of liquid desiccant predecessors, using heat pump unit as the heat source, through theoretical calculation and comparative analysis of condensation dehumidification, dehumidification and solution dehumidification indoors only energy consumption wet load and efficiency (exergy). The desiccant air conditioning system of high energy consumption, put forward the combination of desiccant and air source heat pump, heat pump High temperature exhaust compressor and condenser heat regenerative desiccant dehumidifier to reduce energy consumption, undertake indoor wet load, high temperature / low temperature cold water heat pump hot water through the radiation plate to the indoor cooling / heating. The main component of air conditioning system of desiccant and air source heat pump was designed, and the enthalpy difference lab building the test stand. The research of desiccant wheel the results show that the simulation results agree well with the experimental data and simulation prove correct procedures available; increasing the regeneration air temperature, reduce the regeneration air moisture content, lower processing temperature of inlet air can make the dehumidification quantity increase, reduce the air humidity of inlet velocity, reduce regeneration the wind speed and processing of desiccant wheel is decreased; different operating conditions, corresponding to different optimal speed and the optimal regeneration area and area ratio of desiccant cooling dehumidification, turn Calculation shows that the energy consumption of liquid desiccant dehumidification and wheel, in design condition, the minimum power consumption (condensation dehumidification, exergy efficiency is the highest, and desiccant) of the consumption of the largest (exergy) efficiency is the lowest; indoor humidity is small, condensation dehumidification performance degradation. The load characteristics of Zhenjiang area of a residential study the object, combined with the actual operation of air conditioning system of desiccant wheel and the air source heat pump, the condition in the design of the refrigerating capacity of the system can reach 14.76kW, dehumidification capacity 8.1g/kg, can meet the requirements of heat and humidity load. In summer, the whole system can reach 4.1 COP, saving 13.6% than the traditional air conditioning system; winter heating operation system COP is 3.68, 20%. energy than the traditional air conditioning system
