【摘要】：能源如何利用是当前人们特别关注的问题。天然气这种能源在目前及未来都是我国值得大力开发利用的能源。用天然气代替燃煤在我国已经有一段时间并将持续进行。天然气直燃机作为近年来燃气利用设备的主流,在许多城市已经大面积的使用,在能源的合理利用上有所成效,其本身也具有许多优点。本研究是以某酒店建筑能源技术的实际应用工程作为实例,进行分析研究,将直燃冷温水机组供冷热及电制冷供夜间负荷的运行方案进行技术与经济的比较,确定技术性和经济性合理的系统运行方案。根据项目的要求,预测和计算热负荷和冷负荷的特点与需求,并以此得出了年供能总量作为项目的方案选择依据和参数。比较了用燃气及用电供能的成本,计算出了用燃气供能的成本更低。针对酒店建筑的用能特点和用能的规律,从两套方案中选择出全部空调负荷由直燃机供应的燃气供能系统方案。对项目的投资、运行费用和不确定性进行了分析。通过对某酒店的供能方案和实际运行数据的分析比较,可以看出:酒店建筑采用直燃机替代电空调+燃煤锅炉,可以提高天然气的使用效率和用量,对扩大燃气用户,开拓市场,起到良好的示范效应。
[Abstract]:How to use energy is a problem that people pay special attention to at present. Natural gas is an energy worth developing and utilizing in our country at present and in the future. The replacement of coal with natural gas has been and will continue in China for some time. As the mainstream of gas utilization equipment in recent years, natural gas direct-fired engine has been widely used in many cities, and has achieved some results in the rational utilization of energy, and it also has many advantages. Taking the practical application engineering of building energy technology in a hotel as an example, this paper analyzes and studies the operation scheme of direct-fired cold water unit for cooling and heating and electric refrigeration for night load, and makes a technical and economic comparison. Determine the technical and economical system operation plan. According to the requirements of the project, the characteristics and requirements of heat load and cooling load are predicted and calculated, and the total annual energy supply is obtained as the basis and parameter of project scheme selection. Compared with the cost of gas and electric energy supply, the cost of gas energy supply is lower. According to the characteristics and rules of energy use in hotel buildings, the scheme of gas energy supply system with all air conditioning load supplied by direct gas turbine is selected from two sets of schemes. The investment, operation cost and uncertainty of the project are analyzed. Through the analysis and comparison of the energy supply scheme and the actual operation data of a hotel, it can be seen that the use efficiency and consumption of natural gas can be improved by using direct gas generator instead of electric air conditioning coal-fired boiler in hotel building, and the gas users can be expanded. Open up the market, play a good demonstration effect.
