AB - 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.
