THERMODYNAMIC ANALYSIS FOR INDUSTRIAL CABINET PROVIDING SIMULTANEOUS HEATING AND COOLING THAT CAN BE USED IN THE FOOD INDUSTRY
ABSTRACT
In this study, a thermodynamic analysis of an industrial cabinet designed for industrial cabinet systems used in the food industry and providing simultaneous heating and cooling has been made. During the study, energy and exergy analyzes were carried out by using the engineering equation solver program to thermodynamic analysis of seven different refrigerants in the system designed by determining the mass-flow rate to obtain 10 kW heating power, which was selected by using the coolselector two program by using the refrigerant temperature values and operating pressure values. The condenser dew point temperature was kept at +30°C and the evaporator dew point temperature was kept at -1°C. Calculations were made under atmospheric conditions by keeping subcooling at -2°C, superheating at +5°C, and ambient temperature at 20°C. The coefficients determining the system performance were obtained for the highest R22 refrigerant and the lowest for R513A refrigerant. The exergy heating efficiency was obtained in the highest R22 and lowest R407C refrigerants, respectively. The calculated exergy cooling efficiencies were observed to be the highest R407C and the lowest R513A, respectively. The results of the study are presented in graphics. It has been revealed that the most suitable fluid in the designed industrial cabinet system is the system using R22.
