【摘要】：隨著我國經(jīng)濟的快速發(fā)展和人民生活品質(zhì)的不斷提升，夏熱冬冷地區(qū)的采暖面積和采暖能耗呈現(xiàn)了從無到有、成倍增長的趨勢。為改善冬季室內(nèi)熱環(huán)境及提高熱舒適性，如何在不同的采暖方式中，選擇合適的采暖方式，是我國建筑節(jié)能領域亟待解決的一個重要問題。 本文以夏熱冬冷地區(qū)典型住宅采暖方式為研究對象，從熱舒適性、經(jīng)濟性和適用性三個方面進行研究，分析四種不同采暖方式的特點，以提高采暖方式選擇的科學性。主要內(nèi)容及成果如下： （1）針對夏熱冬冷地區(qū)某城市同一住宅，建立四種采暖方式的建筑模型，分別模擬其室內(nèi)速度場和溫度場。并基于多種熱環(huán)境變量，對室內(nèi)熱環(huán)境進行研究。得出地板輻射采暖和輻射型地板嵌入散熱器采暖能夠滿足室內(nèi)熱環(huán)境要求，而普通散熱器采暖、壁掛式空調(diào)采暖的室內(nèi)工作溫度分別比其低1.5~3℃、1.5~4.5℃，不能滿足熱環(huán)境要求。 （2）利用PMV-PPD評價指標，對四種采暖方式下人體的熱舒適性予以對比分析。地板輻射采暖（PPD≤8.2%）的熱舒適性最高，而輻射型地板嵌入散熱器采暖（PPD≤8.3%）、普通散熱器采暖（10%≤PPD≤15%）、壁掛式空調(diào)采暖（27%≤PPD≤40%）的熱舒適性依次降低，其中前兩者能解決冬季足部寒冷問題。 （3）分析同一住宅四種采暖系統(tǒng)的初投資。研究表明，壁掛式空調(diào)采暖的初投資最低，輻射型地板嵌入散熱器采暖、地板輻射采暖、普通散熱器采暖等的初投資將分別增加168%、126%、117%。 （4）以壽命周期成本作為經(jīng)濟性評價指標，投資期限按四種采暖設備中最長使用壽命20年進行計算，不足20年則按幾次投入成本計算，分析四種采暖方式的壽命周期成本。結果表明，輻射型地板嵌入散熱器采暖的壽命周期成本最高，相應地采用地板輻射、普通散熱器、壁掛式空調(diào)方式可分別降低11%、15%、49%。 （5）就四種采暖方式，，對其經(jīng)濟性與熱舒適性進行定量分析，并對其熱源形式、節(jié)能環(huán)保性和運行維護等方面進行定性分析，研究其適用性。得出地板輻射采暖適合于連續(xù)使用或?qū)崾孢m性要求較高的家庭，不適合于上班族和家具覆蓋地板面積較大的房間。壁掛式空調(diào)采暖適合于低收入家庭，不適合于冬季室外氣溫通常低于-5℃的環(huán)境，或?qū)υ肼�、空氣清潔度控制嚴格或油煙較重的房間。普通散熱器采暖適合于外圍護結構保溫性能較差或冷風滲透較大的住宅，不適合層高較高的住宅。輻射型地板嵌入散熱器采暖對熱舒適性要求較高家庭和上班族均適合，但對低收入家庭不適合。
[Abstract]:With the rapid development of China's economy and continuously enhance people's living quality, hot summer and cold winter heating area and heating energy consumption is from exponentially growing trend. In order to improve the indoor thermal environment in winter and improve thermal comfort, how the different heating methods, select the appropriate heating mode, is one of the most important problem to be solved in the field of building energy efficiency in our country.
Taking the typical residential heating mode in hot summer and cold winter area as the research object, this paper studies the three aspects of thermal comfort, economy and applicability, analyzes the characteristics of four different heating modes, so as to improve the scientificalness of heating mode selection. The main contents and achievements are as follows:
(1) for a city in hot summer and cold winter area with a residential building model of four kinds of heating methods, respectively, to simulate the indoor velocity field and temperature field and thermal environment. Based on a variety of variables, research on indoor thermal environment. The radiant floor heating and radiant floor heating embedded heat exchanger can meet indoor heat the environmental requirements, and common radiator heating, indoor temperature of wall mounted air conditioning heating respectively, which is lower than 1.5~3 DEG C, 1.5~4.5 C, thermal environment can not meet the requirements.
(2) the use of PMV-PPD evaluation index, on the human thermal comfort under four kinds of heating methods are compared. Analysis of radiant floor heating (PPD = 8.2%) the highest thermal comfort, and embedded in the floor radiation heating radiator (PPD = 8.3%), common radiator heating (PPD = 10% ~ 15%), wall mounted air conditioner heating (PPD = 27% ~ 40%) in order to reduce the thermal comfort, the former two can solve the winter cold feet.
(3) analyze the initial investment of four heating systems in the same residential area. The research shows that the initial investment of wall mounted air conditioning heating is the lowest, and the initial investment of radiant floor heating, radiant floor heating and ordinary radiator heating will increase by 168%, 126%, 117%. respectively.
(4) to the life cycle cost as economic evaluation index, the investment period according to four kinds of heating equipment in the long service life of 20 years calculated, less than 20 years, according to several times the cost calculation, life cycle cost analysis of four kinds of heating methods. The results show that the radiation type floor heating radiator embedded in the life cycle the highest cost, accordingly the floor radiation, ordinary radiator, air conditioning type wall can be reduced by 11%, respectively, 15%, 49%.
(5) four kinds of heating methods, the economy and the thermal comfort of quantitative analysis, and the heat source, energy saving and environmental protection and operation and maintenance and other aspects of qualitative analysis, research on its applicability. The radiant floor heating system is suitable for continuous use or the thermal comfort requirements of the higher family, not suitable for to the furniture workers and covering large area floor. Wall mounted air conditioning heating is suitable for low income families, not suitable for the winter outdoor temperature is usually lower than -5 DEG C, or on the noise, the strict control of air cleanliness or fumes heavier room. Common radiator heating is suitable for building envelope insulation performance is poor or cold. Penetration of the larger house, not suitable for high storey residential. Radiation type heating radiator embedded in the floor are suitable for the thermal comfort requirements of higher household and office workers, but not for low income households.
