The generator only uses heat released by burning about 35% of the natural gas (or other fuel) to generate electricity,if most of the waste heat can't be used, it is not only a serious waste of energy, but also a thermal pollution.
Combined cooling heating and power chiller can use a set of heat recovery device to retrieve fully heat produced by the high-temperature exhaust gas, jacketed water and waste heat of low-temperature water circulation, and then use the heat to achieve cooling, heating and power chiller will raise the ratio of energy utilization from 35%(only generating power) to 85%(when using combined cooling heating and power), which realize the cascade utilization of energy and significant energy-saving effect.
