Bu çaly?mada, buhar syky?tyrmaly bir so?utma sisteminde a?yry so?utma ve a?yry kyzdyrma ysy de?i?tiricilerinin termo-ekonomik optimizasyonu yapylmy?tyr. So?utucu aky?kan R22 ve onun alternatifleri olan R410A ve R407C için kondenser sycaklyk araly?y (35°C – 55°C) ve evaporatör sycaklyk araly?y (-10°C – 10°C) alynarak hesaplamalar yapylmy?tyr. So?utma sisteminin II. Kanun analizi yapylarak tüm sistem termo-ekonomik olarak optimize edilmi?tir. Sonuç olarak, verilen sycaklyk aralyklaryna göre optimum a?yry kyzdyrma ve a?yry so?utma ysy de?i?tiricileri alanlary hesaplanmy?tyr.

This study deals with the thermo-economic optimization of superheating and sub-cooling heat exchangers in vapor compressed refrigeration system. Using for R22 and its alternative refrigerants (R410A and R407C), the temperature of condenser at the interval of (35°C – 55°C) and temperature of evaporator at the interval of (-10°C – 10°C) have been obtained from the calculation process. The second law analysis of refrigeration system is carried out and then the whole system is optimized by thermo-economically. As a result of calculations, optimum superheating and sub-cooling temperatures of heat exchangers areas corresponding to these temperatures are obtained. Keywords: Thermo-economy, optimization, alternative refrigerants (R410A and R407C)
