【摘要】：热泵技术在全世界大力发展,利用该技术将空气、水、土壤等中的低品位能转化为高品位能,是节约能源,保护环境的一个很重要的方法,热泵冷暖空调及热水系统被研究也逐渐被使用,热泵冷暖空调及热水系统的使用和推广对节能降耗、环境保护有较深远的影响。该文以湖北省武汉市某高级宾馆为对象,对空气源及湖水源热泵冷暖空调及生活热水系统在实际项目中的运行情况进行分析总结。首先分别介绍了空气源及湖水源热泵冷暖空调及热水系统的运行流程、技术优势及其性能系数。然后根据建筑概况计算空调及热水的冷热负荷并选择系统方案,对采用空气源及湖水源热泵冷暖空调及生活热水系统与采用冷水机组及燃气锅炉等系统进行比较,详细分析计算了各方案的初期投资成本、运行能耗、运行费用和污染物排放量等。结果表明,空气源及湖水源热泵冷暖空调及热水系统的运行能耗最低,排放的污染物最少,综合评价最优。最后在空气源及湖水源热泵冷暖空调及热水系统投入使用后,对房间室内温度、热水出水温度进行测量记录分析,结果表明,空气源及湖水源热泵冷暖空调及热水系统能够满足宾馆的使用要求,达到了暖通空调设计要求,同时对空气源及湖水源热泵冷暖空调及生活热水系统全年的运行能耗进行了长达一年的监测,并与原系统进行对比。通过数据实测,得出空气源及湖水源热泵机组在湖北省武汉市某宾馆的实际运行数据,2014年比2011年及2012年两年总费用的平均值减少了103.3万元,相比原系统,运行费用节约17.2%;按照折标煤能耗计算,节约标准煤555.3吨,节能率高达33.6%,减少二氧化碳排放1538.3吨,降低了对环境的污染。证明了空气源及湖水源热泵冷暖空调及生活热水系统在湖北武汉地区的经济性和适用性,可为空气源及湖水源热泵冷暖空调及生活热水系统在类似地区的使用提供有价值的参考和指导。
[Abstract]:Heat pump technology has been developed all over the world. It is an important way to save energy and protect the environment by converting the low grade energy of air, water and soil into high grade energy. The use and popularization of heat pump air conditioning and hot water system have a profound impact on energy saving and environmental protection. In this paper, an advanced hotel in Wuhan, Hubei Province is taken as an object to analyze and summarize the operation of air source and lake water source heat pump air conditioning and domestic hot water system in the actual project. Firstly, the operation flow, technical advantage and performance coefficient of air source and lake water source heat pump air conditioning and hot water system are introduced respectively. Then according to the general situation of the building, the cooling and heat loads of air conditioning and hot water are calculated and the system scheme is selected. The air source and lake water source heat pump cold and warm air conditioning and domestic hot water system are compared with those using chillers and gas fired boilers, etc. The initial investment cost, operation energy consumption, operating cost and pollutant emission of each scheme are analyzed and calculated in detail. The results show that the air source and lake water source heat pump air conditioning and hot water system have the lowest energy consumption and the least pollutant emission, and the comprehensive evaluation is the best. Finally, after the air source, the lake water source heat pump air conditioning and the hot water system are put into use, the indoor temperature and the water outlet temperature of the room are measured and analyzed. The results show that, Air source and lake water source heat pump air conditioning and hot water system can meet the requirements of the hotel and meet the design requirements of HVAC. At the same time, the annual energy consumption of air source, lake water source heat pump, air conditioning and domestic hot water system is monitored for up to one year, and compared with the original system. The actual operation data of air source and lake water source heat pump units in a hotel in Wuhan, Hubei Province, are obtained through the measured data. The average total cost of 2014 is 1.033 million yuan less than that of 2011 and 2012, compared with the original system. According to the energy consumption of standard coal, 555.3 tons of standard coal is saved, the energy saving rate is up to 33.6, the emission of carbon dioxide is reduced by 1538.3 tons, and the pollution to the environment is reduced. The economy and applicability of air source and lake water source heat pump air conditioning and domestic hot water system in Wuhan area of Hubei province are proved. It can provide valuable reference and guidance for the use of air source and lake water source heat pump air conditioning and domestic hot water system in similar areas.
