【摘要】：空氣源熱泵直接地板輻射供暖系統(tǒng)是一種新型供暖方式，它將節(jié)能環(huán)保的空氣源熱泵技術與制冷劑直接地板輻射供暖技術相結(jié)合，有效提高供熱效率，并且因其良好的經(jīng)濟性和舒適性，可使此系統(tǒng)廣泛應用于城鎮(zhèn)和農(nóng)村居民住宅建筑。除此之外，本系統(tǒng)可根據(jù)用戶的作息等條件靈活設定房間溫度和系統(tǒng)啟停時間，進一步提升了系統(tǒng)的節(jié)能效果。本文通過TRNSYS軟件對某建筑的空氣源熱泵直接地板輻射供暖系統(tǒng)進行了模型的建立，將模擬所得數(shù)據(jù)與實地測量數(shù)據(jù)進行比較，驗證模型達到了很好的仿真效果。在此基礎上，本文提出了全天連續(xù)運行、白天運行夜間停機、谷價運行峰價停機三種不同的運行方式，利用系統(tǒng)模型對這三種運行方式進行模擬，比較這三種運行方式在舒適性和經(jīng)濟性等方面的優(yōu)劣，為空氣源熱泵直接地板輻射供暖系統(tǒng)的推廣和應用起到一定的指導意義。本文的研究內(nèi)容及結(jié)論如下： 1、建立了空氣源熱泵直接地板輻射供暖系統(tǒng)主要部件的數(shù)學模型和建筑熱負荷數(shù)學模型，為系統(tǒng)模型的建立提供了理論支撐。 2、通過對某安裝了空氣源熱泵直接地板輻射供暖系統(tǒng)的建筑進行實地測定，證明此系統(tǒng)以白天運行夜間停機的運行方式供暖可基本達到室內(nèi)溫度白天20℃,夜間16℃，并通過比較實測與模擬的動態(tài)室內(nèi)平均溫度和室內(nèi)動態(tài)熱負荷等參數(shù)，分析得出模擬數(shù)據(jù)與實際工況吻合，證明了模型可代替實際系統(tǒng)工況，達到了仿真模擬的效果。 3、使用系統(tǒng)模型模擬了三種運行方式下采暖季的室內(nèi)動態(tài)溫度、動態(tài)熱舒適度、逐日系統(tǒng)平均性能系數(shù)和逐日系統(tǒng)耗電量，綜合比較分析得出，在基本滿足舒適性條件下，白天運行夜間停機運行方式節(jié)能性優(yōu)于全天連續(xù)運行方式和谷價運行峰價停機運行方式；當電價采用統(tǒng)一電價或階梯電價時，白天運行夜間停機運行方式的經(jīng)濟性較好,當電價采用峰谷電價時，谷價運行峰價停機運行方式經(jīng)濟性較好，但其節(jié)能性較差。綜合節(jié)能性和經(jīng)濟性，白天運行夜間停機運行方式最佳。 4、使用費用年值法對空氣源熱泵直接地板輻射供暖的經(jīng)濟性進行了詳細的計算和分析，并與幾種常見供暖方式在初投資費用、運行費用和費用年值等分項分別比較，從數(shù)據(jù)中可以看出，空氣源熱泵直接地板輻射供暖系統(tǒng)的經(jīng)濟性方面在幾種常見供暖方式中處于中間位置；從一次能源的消耗量方面計算分析了這幾種供暖方式的節(jié)能性，由計算結(jié)果可知，空氣源熱泵直接地板輻射供暖系統(tǒng)的節(jié)能性最佳。綜合考慮經(jīng)濟效益、環(huán)保效益、社會效益和節(jié)能效益，，空氣源熱泵直接地板輻射供暖系統(tǒng)是較好的供暖方式。
[Abstract]:The air source heat pump direct floor radiant heating system is a new type of heating system. It combines the energy saving and environmental air source heat pump technology with the refrigerant direct floor radiant heating technology. It can effectively improve the heating efficiency. And because of its good economy and comfort, this system can be widely used in urban and rural residential buildings. In addition, this system can flexibly set room temperature and start and stop time according to the conditions of user's rest and rest, and further enhance the efficiency of the system. This paper has built a model of the air source heat pump direct floor radiant heating system of a building by TRNSYS software, and the simulated data and the field measurement data are carried out. Comparison, the verification model has achieved good simulation results. On this basis, this paper puts forward three different operating modes, which are running in a continuous day, running at night in the daytime, running peak price of valley price, and using the system model to simulate the three modes of operation, and compare the advantages of the three operation modes in the aspects of comfort and economy. Poor quality will play a guiding role in the promotion and application of air source heat pump direct floor radiant heating system. The research contents and conclusions in this paper are as follows:
1, the mathematical model of the main components of the air source heat pump direct floor radiant heating system and the mathematical model of the heat load of the building are established, which provide the theoretical support for the establishment of the system model.
2, through the field measurement of the building of a direct floor radiant heating system with an air source heat pump, it is proved that the system can basically reach the indoor temperature of 20 and 16 at night by daytime running at night, and by comparing the measured and simulated indoor average temperature and indoor dynamic heat load. It is proved that the model can replace the actual system condition and achieve the effect of simulation.
3, the system model is used to simulate the indoor dynamic temperature, the dynamic thermal comfort, the daily average performance coefficient and the daily system consumption of the daily system in the heating season under the three operating modes. The comprehensive comparison and analysis shows that under the basic comfort conditions, the energy saving of the daytime operation at night is better than the whole day continuous operation mode and the valley price. When the electricity price adopts the unified electricity price or the ladder electricity price, the economy of running at night in the night is better. When the electricity price adopts peak valley electricity price, the operation mode of the valley price peak price stop operation is better, but its energy saving is poor. The way is best.
4, the cost annual value method is used to calculate and analyze the economy of air source heat pump directly floor radiant heating. It is compared with several common heating methods in initial investment, operation cost and annual cost. It can be seen from the data that the economic aspects of air source heat pump direct floor radiant heating system can be seen from the data. It is in the middle position of several common heating methods; the energy saving of these heating modes is calculated and analyzed from the consumption of the primary energy. The results show that the energy saving of the air source heat pump direct floor radiant heating system is the best. The comprehensive consideration of the economic benefit, the benefit of the ring, the social and energy efficiency, the air source heat The pump direct floor radiant heating system is a better way of heating.
