CCHP Load Plan Power Summer: Max load is 2.8 MW and the min load is 1.0 MW. Winter: Max load is 2.4 MW and the min load is 0.5MW. C li d H ti Cooling and Heating Summer: Max cooling load is 6840KW/h and supply/return water temp is 7-12℃. Winter: Max heating load is 5900KW/h and supply/return water temp is 60-50℃. System System Power Gas engine for independent power supply, utility power acts as standby and make-up Cooling Cooling 1 unit of flue gas + jacket water with burner chiller 1 unit of direct-fired chiller as standby Flue gas temp: about 500℃, Jacket water temp: 90℃. Heating Exhausted flue gas from chiller produces hot water for a 65m3 hot water tank for 24 hours sanitary hot water supply, 1 unit of 1.86 MW gas fired-boiler makes up inadequate hot water.
