某酒店天然气冷热电三联供改造研究

Research on the Transformation of Natural Gas Cooling Heating and Power Generation

以贵阳市观山湖区某酒店的冷热电三联供系统改造为研究对象,分析建筑的供冷、供暖期典型日的逐时冷热电负荷。基于全年适时负荷,按以热定电思路确定发电设备容量。通过分析发现:全年逐时动态冷热负荷的分析十分重要,不仅是确定设备容量的需要,也是分析运行成本的需要;确定发电机容量时需要合理选定发电机的开机时间及运行策略。

Taking the transformation of the combined cooling,heating and power supply system of a hotel in Guanshanhu District of Guiyang City as the research object,analyze the hourly cooling,heating and power load of a typical day during the cooling and heating period of the building.Based on the timely load throughout the year,the capacity of the power generation equipment is determined according to the idea of determining heat and electricity.Through analysis,it is found that the analysis of the hourly dynamic cooling and heating load throughout the year is very important.It is not only the need to determine the equipment capacity,but also the need to analyze the operating cost;when determining the generator capacity,it is necessary to reasonably select the generator's start-up time and operating strategy.
