Abstract

Bu çalışmada, iki kademeli, ara soğutmalı buhar sıkıştırmalı bir soğutma sisteminde soğutucu akışkan ve kondenser türünün performans katsayısı değerine etkisi tasarlanan cihaz ile deneysel olarak incelenmiştir. Deneyler için tasarlanmış toplam sekiz konfigürasyon vardır ve bunlar birbiriyle kıyaslanmıştır. Deney aşamasında bakır borulu kondenser, mikro kanallı kondenser, R404A ve R449A gazları tasarlanan cihazda kullanılmıştır. Bu çalışmanın ana odak noktası, kondenser tipinin, soğutucu gazların ve kompresör sayısının buhar sıkıştırmalı bir soğutma sisteminde performans katsayısı üzerindeki etkisini araştırmaktır. Bu çalışmada mikro kanallı kondenser kullanan tasarımların bakır boru kondenser kullanan tasarımlara göre daha yüksek performans katsayısı değerine sahip olduğu ve sistem için en verimli tasarımın mikro kanal kondenser kullanan ve R449A gazı ile çalışan tasarım olduğu sonucuna varılmıştır.

The Effect of Condenser Type and Refrigerant Type on the Two-Stage Vapour Compression Refrigeration System: An Experimental Study

Year 2023, , 983 - 990, 05.07.2023
https://doi.org/10.2339/politeknik.1221179

Abstract

In this study, the effects of refrigerants and condenser type on the coefficient (COP) of performance value in a two-stage intercooled vapour compression refrigeration system have been investigated experimentally with the designed device. There is a total of eight configurations designed for experiments, and these are compared with each other. During the experiments, a copper tube condenser, a micro-channel condenser, and R404A and R449A refrigerants were used in the designed device. The main focus of this study is to investigate the effect of condenser type, refrigerants, and the number of compressors on the COP in a vapor compression refrigeration system. In this study, it was concluded that designs using a micro-channel condenser have a higher COP than designs using a copper tube condenser, and the most efficient design for the system is the one using the micro-channel condenser and working with R449A refrigerant.
