【摘要】：高海拔寒冷地區(qū)具有海拔較高、氣壓低、氣溫低等特點，春秋兩季較短，冬季嚴寒漫長，供暖能耗占建筑總能耗的比例較高。高海拔寒冷地區(qū)缺乏常規(guī)能源，且交通運輸不便，但高海拔寒冷地區(qū)太陽輻射強，大部分地區(qū)處于太陽能資源一類和二類地區(qū)，利用當(dāng)?shù)刎S富的太陽能資源供暖已經(jīng)成為高海拔寒冷地區(qū)供暖的一個重要選擇。在太陽能供暖系統(tǒng)中，合理的設(shè)計對系統(tǒng)運行至關(guān)重要，但目前在高海拔寒冷地區(qū)，針對太陽能供暖系統(tǒng)（特別是直接供暖模式）全供暖季性能及設(shè)計優(yōu)化的研究很少。因此，本文的目的在于以紅原機場太陽能供暖系統(tǒng)為基礎(chǔ)，研究太陽能供暖系統(tǒng)在高海拔寒冷地區(qū)的運行性能，優(yōu)化太陽能供暖系統(tǒng)在高海拔寒冷地區(qū)的系統(tǒng)配置，為太陽能供暖系統(tǒng)在高海拔寒冷地區(qū)的應(yīng)用提供一定的指導(dǎo)。 首先，本文利用DeST對以紅原為代表的高海拔寒冷地區(qū)的室外氣候特征及紅原機場中不同類型建筑的自然室溫和熱負荷進行分析，對高寒地區(qū)室內(nèi)熱環(huán)境的調(diào)控提供指導(dǎo)。 其次，建立了紅原機場太陽能+水源熱泵供暖系統(tǒng)數(shù)學(xué)模型，介紹了本文所研究的紅原機場太陽能供暖系統(tǒng)的基本原理和運行模式，詳細地給出太陽能集熱器、水源熱泵、蓄熱水箱及系統(tǒng)控制策略的數(shù)學(xué)模型。 再次，，根據(jù)太陽能+水源熱泵供暖系統(tǒng)的主要組件的數(shù)學(xué)模型，選擇適合本文所研究系統(tǒng)的TRNSYS部件。利用TRNSYS自帶的的水源熱泵部件與EQUTATION，將文中所建立的水源熱泵數(shù)學(xué)模型與TRNSYS中的水源熱泵模型結(jié)合起來建立本文模擬所需要的水源熱泵TRNSYS部件。在此基礎(chǔ)上建立所研究太陽能+水源熱泵供暖系統(tǒng)的TRNSYS模型，并利用實測數(shù)據(jù)對系統(tǒng)TRNSYS模型的正確性進行驗證，進而對太陽能+水源熱泵供暖系統(tǒng)的運行性能進行分析，并與水源熱泵供暖系統(tǒng)和燃氣鍋爐供暖系統(tǒng)進行經(jīng)濟性和節(jié)能性的對比分析。 最后，在太陽能+水源熱泵供暖系統(tǒng)TRNSYS模型及運行特性分析的基礎(chǔ)上，對太陽能集熱器的安裝角度、蓄熱裝置體積、太陽能集熱器面積和供暖溫度進行了優(yōu)化，考察這些參數(shù)對系統(tǒng)性能的影響。以經(jīng)濟性和節(jié)能性為優(yōu)化指標(biāo)，兼顧系統(tǒng)性能，提出紅原機場太陽能供暖系統(tǒng)適宜的系統(tǒng)配置，為高海拔寒冷地區(qū)太陽能供暖系統(tǒng)的應(yīng)用提供一定的指導(dǎo)。
[Abstract]:The cold area at high altitude has the characteristics of high altitude, low air pressure and low temperature. The spring and autumn seasons are short, the winter is long, the heating energy consumption is high in the total building energy consumption, and the high altitude cold area is short of conventional energy, and transportation is not convenient. However, the solar radiation is strong in cold areas at high altitudes, and most of the areas are in the first and second class areas of solar energy resources. Heating with abundant local solar energy resources has become an important choice for heating in cold areas at high altitudes. In solar heating systems, reasonable design is essential to the operation of the system, but at present in cold areas at high altitudes, There is little research on the performance and design optimization of solar heating system (especially direct heating mode). Therefore, the purpose of this paper is to base on the solar heating system of Hongyuan Airport. This paper studies the performance of solar heating system in cold regions at high altitude and optimizes the configuration of solar heating system in cold regions at high altitude, which provides some guidance for the application of solar heating systems in cold regions at high altitude. Firstly, DeST is used to analyze the outdoor climate characteristics of the high altitude cold area represented by Hongyuan, and the natural room temperature and heat load of different types of buildings in Hongyuan Airport, which provides guidance for the regulation and control of indoor thermal environment in the alpine area. Secondly, the mathematical model of the solar energy source heat pump heating system in Hongyuan Airport is established, the basic principle and operation mode of the solar energy heating system of Hongyuan Airport are introduced in this paper, and the solar collector and water source heat pump are given in detail. Mathematical model of heat storage tank and system control strategy. Thirdly, according to the mathematical model of the main components of the solar water source heat pump heating system, Select the TRNSYS parts suitable for the system studied in this paper. By using the water source heat pump components and EQUTATION of TRNSYS, the mathematical model of water source heat pump established in this paper is combined with the water source heat pump model in TRNSYS to establish the simulation requirements of this paper. On the basis of this, the TRNSYS model of solar water source heat pump heating system is established. The correctness of the TRNSYS model of the system is verified by the measured data, and the operation performance of the solar water source heat pump heating system is analyzed. Compared with water source heat pump heating system and gas boiler heating system, the economy and energy efficiency are analyzed. Finally, on the basis of TRNSYS model and operation characteristic analysis of solar water source heat pump heating system, the installation angle of solar collector, the volume of heat storage device, the area of solar collector and the heating temperature are optimized. The influence of these parameters on the system performance is investigated. Taking the economy and energy saving as the optimization index and taking the system performance into account, the suitable system configuration for the solar energy heating system of Hongyuan Airport is put forward. It provides some guidance for the application of solar energy heating system in cold area at high altitude.
