Optimization of Hospital Energy Supply Mode Based on Gas Distribution

The Gas Distributed Energy System (CCHP) can realize the cascade, circulation, and efficient use of energy, and effectively avoid multiple conversions and transmission losses. It is close to the "direct supply" characteristics of the load side, and has high energy utilization efficiency and economic benefits. In order to meet the scientific matching between the load side and the source side, the S Hospital was used as the research object, its energy load data and meteorological data were tested for one year, and the collected data were counted, sorted, analyzed, and obtained Load characteristics of S hospital. Three energy supply schemes were drawn up, and the best scheme was selected according to the design principle of "using heat to determine electricity" and the annual comprehensive rate method. Calculations show that: the installed capacity of the project is 0.6 MW, the initial investment is 6.718 million yuan, the financial internal rate of return is 15.98%, and the investment payback period is 6.63 years; the market, economy, policy, technology and other risks are controllable. For this reason, for scenarios where there is a demand for cooling, heating, and electricity, and the load is stable, and the scale of energy consumption is small, it is suitable to use gas distributed energy supply.
