Energy Technology Application Research Of A Hotel Building

Energy utilization has become a common concern of mankind. Natural gas is worth to develop and use in our country at present and in the future for a period of time. Replacing coal with natural gas has been going on for some time in our country and will continue.Natural gas direct combustion engine as the mainstream of gas utilization equipment in recent years,has been widely used in many cities,it has achieved success in the rational use of energy resources and it also has many advantages.This study takes a practical application project of building energy technology in a hotel as an example to analyze , to compare the operation scheme of the direct fired cold and warm water chiller for cooling for night load of the technical and economic, determine the reasonable system operation plan of the technical and economical.According to the requirements of the project,prediction and calculation the characteristics and requirements of heat load and cold load, as a result, the total annual energy supply is chosen as the basis and parameters of the project selection. Compared the cost of using gas and electricity for energy supply , it is calculated that the cost of gas energy supply is lower. According to the characteristics of energy use and the law of energy usage, the scheme of the gas energy supply system,which is supplied by the direct combustion engine,is selected from the two sets of air conditioning loads. To analyzed the investment, operating cost and uncertainty of the project.Through analyzing and comparing the energy supply scheme and the actual running data of a hotel ,we can know that hotel using direct fired machine instead of electric air conditioner coal-fired boiler can improve the efficiency and dosage of natural gas, play a good demonstration effect on the expansion of gas users, and explore the market.
