本文讨论了热电联产系统中的能量守恒问题。一个蒸汽动力循环（Rankine）产生2MW的电力，蒸汽从涡轮机以7bar的速度排出，在冬季为工厂或建筑物供暖，或在夏季为同一地区的空调提供蒸汽喷射制冷循环。在夏季，该系统可以作为替代溶液，而不是吸收。当然，喷射式制冷机组比吸收式制冷机组更经济。电功率/热量比变化到（0.1-0.4）区域，喷射器循环蒸发器温度变化到（10-16℃）区域。为研究热电联产系统的性能参数，编写了计算机程序。
This paper discusses the conservation of energy in a cogeneration system. A steam power cycle (Rankine) produces electrical power 2MW and steam is bleeded off from the turbine at 7bar to warm a factory or units of buildings during the winter or to supply a steam ejector refrigeration cycle to air-conditioning the same area during the summer. In the summer this system can be as alternative solution instead of absorption. Certainly the ejector refrigeration unit is more economical than absorption unit. The ratio of electrical power/heat is varied into the region (0.1–0.4) and the evaporator temperature of the ejector cycle is varied into the region (10–16°C). A computer program has been developed for the study of performance parameters of the cogeneration system.
