【摘要】：舒適與節(jié)能已成為暖通空調(diào)領(lǐng)域研究與發(fā)展的主題,傳統(tǒng)對(duì)流空調(diào)不僅存在“吹風(fēng)感”,還易引發(fā)一系列衛(wèi)生問題,嚴(yán)重影響人類的身心健康,而毛細(xì)管輻射空調(diào)的誕生卻很好地解決了上述問題。本文將從能耗角度來對(duì)毛細(xì)管輻射空調(diào)進(jìn)行分析。首先對(duì)P.O.Fanger教授提出的熱舒適性方程進(jìn)行編程計(jì)算,得出在選取合適的平均輻射溫度和相同熱舒適性條件下,夏季毛細(xì)管輻射空調(diào)房間的室內(nèi)空氣溫度高于對(duì)流空調(diào)房間的室內(nèi)空氣溫度,冬季則低于對(duì)流空調(diào)的室內(nèi)空氣溫度的結(jié)論,表明選取合適的平均輻射溫度以及合理的新風(fēng)除濕方式可以使毛細(xì)管輻射空調(diào)新風(fēng)系統(tǒng)的能耗得到降低。其次利用C++和Matlab對(duì)計(jì)算熱環(huán)境參數(shù)的熱平衡方程組進(jìn)行編程計(jì)算,得出夏季毛細(xì)管輻射空調(diào)房間外圍護(hù)結(jié)構(gòu)內(nèi)表面溫度會(huì)低于對(duì)流空調(diào)房間外圍護(hù)結(jié)構(gòu)內(nèi)表面溫度,冬季則高于對(duì)流空調(diào)房間外圍護(hù)結(jié)構(gòu)內(nèi)表面溫度的結(jié)論,這表明毛細(xì)管輻射空調(diào)房間的圍護(hù)結(jié)構(gòu)負(fù)荷大于對(duì)流空調(diào)房間的圍護(hù)結(jié)構(gòu)負(fù)荷。而在熱舒適性條件下,綜合考慮了新風(fēng)負(fù)荷,得出了當(dāng)夏季(冬季)毛細(xì)管輻射空調(diào)房間的室內(nèi)空氣溫度滿足()要求時(shí)可以使其負(fù)荷比對(duì)流空調(diào)房間的負(fù)荷低的結(jié)論,這表明毛細(xì)管輻射空調(diào)比對(duì)流空調(diào)更節(jié)能。最后提出依據(jù)平均輻射溫度的建筑設(shè)計(jì)和毛細(xì)管輻射空調(diào)設(shè)計(jì)構(gòu)思,主要通過Fluent的模擬探討了毛細(xì)管席鋪設(shè)面積緊張時(shí)的一些解決措施,并得出在保證夏天不結(jié)露的情況下,應(yīng)優(yōu)先選擇改變供水溫度的結(jié)論。
[Abstract]:Comfort and energy saving have become the subject of research and development in HVAC field. Traditional convective air conditioning not only has "blowing feeling", but also easily leads to a series of health problems, which seriously affects the physical and mental health of human beings. The birth of capillary radiation air conditioning has solved the above problems. In this paper, capillary radiation air conditioning is analyzed from the angle of energy consumption. Firstly, the thermal comfort equation proposed by Professor P.O.Fanger is programmed and calculated, and it is concluded that under the appropriate average radiation temperature and the same thermal comfort condition, The conclusion that the indoor air temperature of the capillary radiation air conditioning room in summer is higher than that of the convection air conditioning room, and that in winter is lower than the indoor air temperature of the convection air conditioning room. It is shown that the energy consumption of the fresh air system of capillary radiation air conditioning system can be reduced by selecting appropriate mean radiation temperature and reasonable fresh air dehumidification mode. Secondly, using C and Matlab to calculate the heat balance equations of thermal environment parameters, it is concluded that the inner surface temperature of the outer envelope structure of the capillary radiation air conditioning room in summer will be lower than that of the convection air conditioning room outside the envelope structure. The conclusion that the inner surface temperature of the outer enclosure structure is higher than that of the convection air conditioning room in winter shows that the envelope structure load of the capillary radiation air conditioning room is greater than that of the convection air conditioning room. Under the condition of thermal comfort, considering the fresh air load, it is concluded that when the indoor air temperature of the capillary radiation air conditioning room meets the requirement in summer (winter), the load can be lower than that of the convection air conditioning room. This shows that capillary radiation air conditioning is more energy efficient than convection air conditioning. Finally, according to the architectural design of mean radiation temperature and the design conception of capillary radiation air conditioning, the paper mainly discusses some measures to solve the tension of capillary mat laying area through Fluent simulation, and draws the conclusion that, under the condition of ensuring that there is no dew in summer, Priority should be given to the conclusion of changing the temperature of the water supply.
