Feasibility energy performance simulation of DHC system with gas engine driven chiller by using LCEM Tool

Hideki Tanaka, Toshiharu Shimizu

Abstract: This paper examines the energy performance of a district heating and cooling (DHC) system with gas engine-driven refrigerating machine (GER) modelled by the Life Cycle Energy Management (LCEM) tool. Cooling Tower Gas AR 60℃ 7℃ The GER can supply chilled water, and an exhaust heat recovery absorption refrigerating machine Cooling Tower Chilled water supply (HRAR) can also produce chilled water by using hot water as waste heat from the gas engine jacket water cooler of GER. In conclusion, assuming an installation capacity ratio of 22% for the GER, a minimum partial load factor of the gas engine of the GER and VWV (variable water volume) water pump flow-control of 45% can be achieved for the system, based on a simulation using actual heating and cooling load data during Gas Cooling Tower Cooling Tower GE GER Gas 11℃ HRAR 60℃ Heat Exchanger C 7℃ Return water Temp. 15℃ H Hot water supply annual operation of a small -scale DHC facilities .
