Abstract Present work deals with the three modes of power generation i.e. cogeneration (or combined heating and power), cogeneration with thermal energy storage and trigeneration with thermal energy storage and their comparison. Stationary compression ignition engine of 4.4 kW was used for power generation and all three modes were experimentally investigated. Cogeneration was achieved by coupling the engine with concentric tube or double pipe type heat exchanger. For cogeneration with thermal energy storage mode above setup was coupled with an erythritol filled shell & tube type heat exchanger and trigeneration with thermal energy storage mode was achieved by the addition of vapour absorption refrigeration system. Experiments were carried out for all three modes and comparative results are reported in this paper. Maximum useful energy output for trigeneration with thermal energy was 7.27 kW at an engine load of 4.4 kW. Reduction in emissions of CO2 in kg/kWh in case of trigeneration with thermal energy storage was 54.92% at a load of 4.4 kW as compared to single generation.

微热电联产、微热储能与微热储能微热电联产对比研究

摘要 目前的工作涉及热电联产（或热电联产）、热能储热联产和热能储热三联电三种发电方式及其比较。4.4 kW 的固定式压燃式发动机用于发电，并对所有三种模式进行了实验研究。热电联产是通过将发动机与同心管或双管式换热器耦合来实现的。对于热能储存模式的热电联产，上述设置与赤藓糖醇填充管壳式换热器相结合，并通过增加蒸汽吸收式制冷系统实现热能储存模式的三联产。对所有三种模式进行了实验，并在本文中报告了比较结果。在发动机负载为 4.4 kW 时，热能三联产的最大有用能量输出为 7.27 kW。与单发电相比，在负载为 4.4 kW 的情况下，在带有热能储存的三联产的情况下，二氧化碳排放量（以 kg/kWh 为单位）减少了 54.92%。
