Wastes produced from several processes are focused on by many scientific researchers in order to reuse them, achieve energy savings, and reduce cost and environmental pollution. Recently, many organizations have utilized a micro-trigeneration system as a primary energy source, as it produces cooling, heat, and power in a combined effect. Various scholars designed numerous trigeneration systems in recent years. However, it is challenging to attain energy-efficient operation. Therefore, this current research focuses on developing an optimal micro combined cooling, heating, and power generation (MCCHP) to improve energy efficiency and reduce cost. The major components of the trigeneration system are the diesel engine, heat exchanger, boiler, absorption chiller, and chilled water storage system. In order to improve the cooling output of the proposed system, a single-stage, double-effect absorption chiller (LiBr-H2O absorption chiller) is utilized with the atom search optimization (ASO) algorithm. The variables of the condenser in the absorption chiller are given as input for optimization. The results show that the proposed system has a cooling capacity of 16 kW. Compared with the existing algorithms, it is efficient with 98% temperature minimization and cost-effectiveness. This micro-trigeneration device can be used in hospitals and the food production industry and is cost-effective.
