Combined cooling, heat, and power (CCHP) systems are very promising for producing demands simultaneously. In the present study, a CCHP system with the geothermal source has been investigated, and heat loads are designed for the micro-scale application. To determine the feasibility of the system, energy analysis is carried out, and results are reported after optimization. Also, the genetic algorithm method is presented for optimization. The sub-objectives of this study are the calculations of water usage and CO₂emission in the manufacturing process. For this matter, energy efficiency, water usage, and CO₂ emission after optimization have been examined as three significant parameters. The efficiency of the system, water usage, and CO₂ emission are reported as 46.4%, 688151.2 (lit) and 13439 respectively. The total purchase cost is 43121 $. Moreover, the results show that between components the maximum water usage in manufacturing and CO₂ emission is belonged to vapor generator with 242010 (lit) and 4701 https://gpj.ui.ac.ir/article_23963_519466a8f6aeafd776cbb4301a85e2f3.pdf
