【摘要】：能源問題已是當(dāng)今世界各國普遍重視的問題，被公認(rèn)為是人類面臨四大生存問題之一，而隨著各國工業(yè)化進(jìn)程的不斷發(fā)展，地球上可供人類利用的石油、煤炭、天然氣等一次燃料資源日漸枯竭，能源危機(jī)已迫在眉睫，如今建筑生活熱水引起的能耗經(jīng)常不受到人們的重視，然而建筑生活熱水負(fù)荷卻占用著很大的能源消耗，人們也往往會因此付上一筆高額的費(fèi)用，再加上人們的生活水平逐漸提高，這部分的費(fèi)用也會逐漸增加，而隨著能源的消耗，能源價格也在每年不同程度的增長，而且實行階梯價格的范圍也會越來越廣。 本文以長安大學(xué)—威能綜合能源利用系統(tǒng)實驗室為基礎(chǔ)，綜合了太陽能、地源熱泵、燃?xì)忮仩t和電鍋爐四種能源應(yīng)用的原理，以西安地區(qū)為例，首先通過matlab編程，將西安水平面上的逐時太陽輻射轉(zhuǎn)變成集熱器在全年最佳傾角下的逐時太陽能輻射，其次分析了綜合能源系統(tǒng)的運(yùn)行模式，并以燃?xì)忮仩t和電鍋爐作為輔助熱源，當(dāng)太陽能熱水系統(tǒng)不能滿足生活熱水需求時，以同一時間段分別滿足生活熱水所消耗的能耗費(fèi)用為能源之間相互切換的判斷條件，通過某賓館生活熱水應(yīng)用分析太陽能輻射量、賓館入住率和能源價格這三種因素之間對控制策略的影響，并提出一套系統(tǒng)控制策略流程圖，最后計算各種策略下系統(tǒng)一年的能耗費(fèi)用，并經(jīng)過經(jīng)濟(jì)分析表明了這種控制策略的優(yōu)越性。 隨著能源價格增長率不同，以能源價格為依據(jù)，在不同時間段產(chǎn)生相同熱量所對應(yīng)的能源能耗費(fèi)用不同，然后依據(jù)能耗費(fèi)用對能源進(jìn)行切換的這種想法在很大程度上能夠降低運(yùn)行能耗費(fèi)用，但是這種能源選擇的控制策略影響因素較多，還需進(jìn)一步細(xì)化和完善，同時為進(jìn)一步實現(xiàn)能源優(yōu)化利用的計算機(jī)控制和管理奠定基礎(chǔ)。
[Abstract]:The energy problem has been paid more and more attention by all countries in the world. It is recognized as one of the four survival problems facing mankind. With the continuous development of industrialization, the oil and coal on the earth can be used by human beings. Natural gas and other primary fuel resources are drying up day by day, energy crisis is imminent. Nowadays, the energy consumption caused by hot water in buildings is often ignored by people, but the load of hot water in buildings occupies a large amount of energy consumption. People tend to pay a lot of money for it, and with people's living standards rising, that part of the cost is going to go up, and with the consumption of energy, energy prices are going up at different levels every year. And the range of ladder prices will be wider and wider. Based on the laboratory of Changan University-Weineng Comprehensive Energy Utilization system, this paper integrates the principles of solar energy, ground-source heat pump, gas-fired boiler and electric boiler. Taking Xi'an area as an example, it is programmed by matlab. The hourly solar radiation from Xi'an horizontal plane is transformed into hourly solar radiation of collector at the optimum inclination angle of the year. Secondly, the operation mode of the integrated energy system is analyzed, and the gas-fired boiler and electric boiler are used as auxiliary heat source. When the solar water heating system can not meet the domestic hot water demand, the energy consumption cost of the domestic hot water consumption in the same time period is taken as the judging condition of switching between the energy sources, and the solar radiation amount is analyzed through the application of the domestic hot water in a certain hotel. The influence of the three factors of hotel occupancy rate and energy price on the control strategy is presented, and a set of system control strategy flow chart is put forward. Finally, the energy consumption cost of the system under various strategies is calculated. The economic analysis shows the superiority of the control strategy. Depending on the energy price growth rate, the energy consumption costs of generating the same amount of heat at different times are different. Then the idea of switching energy according to the cost of energy consumption can reduce the cost of running energy to a great extent, but the control strategy of this kind of energy choice has many factors, which need to be further refined and improved. At the same time, it lays a foundation for the computer control and management of energy optimization.
