چکیده

In the present research a combined cooling heating and power cycle comprising of a micro gas turbine, an adsorption chiller, a thermal damping tank and heat recovery system is proposed and simulated in details. The model of the micro gas turbine is based on available operational data of Capstone micro-gas turbines. The differential equations governing the condenser, evaporator, adsorption/desorption beds, heating and cooling systems are derived, discretized, solved and validated with the literature data and good agreement is achieved. The impact of micro-gas turbines capacity, heating source temperature, and exhaust final temperature on the combined cooling heating and power system performance and its components is studied. Heating source temperature leaving the chiller fluctuates due to the cyclic behavior of the adsorption chiller. To dampen these fluctuations a tank is designed that allows maximum temperature fluctuation of 2 ℃ for the returned heating water before entering the heat recovery system. Two energy and environmental criteria based on overall efficiency, and emission reduction are proposed to find the optimum micro-gas turbine size. The results show that the coefficient of performance of the chiller has reached 0.63 and the primary energy saving of 35% is estimated. The CO2, CO and NOx reduction of 5-45 kg, 4-35 g, and 5-43 g is calculated per hour for the micro-gas turbine sizes from 15-200 kW.
