Abstract Regarding the significance of low-temperature heat sources in combined cooling, heating, and power (CCHP) systems, it is necessary to find practical and economical ways to maximize the efficient use of available energies. Integrating the auxiliary cycle with the main system and changing the configuration are among the useful solutions to achieve this purpose. In this work, a combination of both solutions is presented, accordingly, an absorption heat transformer cycle (AHT) is integrated with a conventional CCHP system, which is made of organic Rankine cycle, absorption refrigeration cycle, and a heat exchanger. Three conventional CCHP systems with sequential (Configuraion1), parallel (Configuraion2) and a combination of sequential and parallel (Configuraion3) configurations are considered. It is shown that among the Configuraion1, Configuraion2, and Configuraion3, Configuraion1 has the highest energy efficiency; therefore, it is selected to be compared with the proposed integrated system with AHT. This integration affects the outputs production and also energy consumption; therefore, four different modes (standpoints) are taken into account to compare the production of power (mode A), cooling (Mode B), heating (mode C), and energy consumption (mode D) of these two systems. Also, from the exergy, environmental, and economic aspects, these two systems are compared. Regarding mode D, it is indicated that the energy and exergy efficiencies, energy consumption and carbon emission of the proposed system are improved 17.68%, 17.68%, 15.03%, and 15.02%, respectively. It is noted that for the heat source stream temperature range of 90 °C–120 °C, the proposed system has better performance than the Configuration1. Despite the additional costs of integrating AHT with the CCHP system, the proposed system has 517018.1 US$/year cost saving (which is 32.65% of the investment cost of Configuration1) if biomass is used as a heat source, which indicates its higher economic advantage than the Configuration1. Also, comparing the proposed system with Configuration1, the amount of power, cooling and heating productions are improved 27.98%, 102.15%, and 36.87%, respectively.

研究将吸收式热变压器与联合冷却、加热和电力系统集成的影响：热力学和经济分析

摘要 关于低温热源在冷热电联供（CCHP）系统中的重要性，有必要寻找实用且经济的方法来最大限度地有效利用可用能源。将辅助循环与主系统集成并更改配置是实现此目的的有用解决方案之一。在这项工作中，提出了两种解决方案的组合，因此，吸收式热变换器循环 (AHT) 与传统的 CCHP 系统集成在一起，该系统由有机朗肯循环、吸收式制冷循环和热交换器组成。考虑了具有顺序 (Configuraion1)、并行 (Configuraion2) 和顺序和并行组合 (Configuraion3) 配置的三个传统 CCHP 系统。结果表明，在 Configuraion1 中，Configuraion2、Configuraion3、Configuraion1的能效最高；因此，选择它与建议的带有 AHT 的集成系统进行比较。这种整合会影响产出和能源消耗；因此，考虑了四种不同的模式（立场）来比较这两个系统的电力生产（模式 A）、制冷（模式 B）、加热（模式 C）和能源消耗（模式 D）。此外，还从火用、环境和经济方面对这两个系统进行了比较。对于模式D，表明该系统的能源和火用效率、能源消耗和碳排放分别提高了17.68%、17.68%、15.03%和15.02%。值得注意的是，对于 90 °C-120 °C 的热源流温度范围，所提出的系统比 Configuration1 具有更好的性能。尽管将 AHT 与 CCHP 系统集成会产生额外成本，但如果使用生物质作为热源，拟议系统每年可节省 517018.1 美元的成本（占配置 1 投资成本的 32.65%），表明其具有更高的经济优势比配置1。此外，将所提出的系统与配置 1 相比，发电量、制冷量和制热量分别提高了 27.98%、102.15% 和 36.87%。
