Abstract

The vapor compression cooling devices operate on the same principle as heat pumps. In these types of machines thermal energy is transferred from the cold environment to the warmer side using provided power by the compressor. In this study, the effect of air flow rate on the cooling performance of vapor compression cooling devices has been investigated by simulating a designed system in AVL CRUISE™ M program. The simulated model is air-to-air cooling machine and refrigerant R134a was used as circulated gas inside the system. COP value of the system has been calculated in different working conditions and obtained results have been fully discussed. Accordingly, enthalpy variation in every element of the heat pump has been calculated in different working conditions and discussed on P-h diagram. This study presents a simulation method that is a practical solution method in the field of heat pumps, cooling machines and refrigerators which can be considered before installing device in order to have a proper prediction of the system performance.

Abstract

Buhar sıkıştırmalı soğutma cihazları ısı pompalarıyla benzer prensipte çalışır. Bu tür makinelerde kompresör tarafından tüketilen gücün kullanılmasıyla soğuk ortamdan sıcak olana ısıl enerji transferi gerçekleştirilir. Bu çalışmada, AVL CRUISE™ M programında tasarlanan bir sistemin simülasyonu yapılarak hava akış hızının buhar sıkıştırmalı soğutma cihazının soğutma performansına etkisi incelenmiştir. Simülasyonu yapılan model havadan havaya soğutma makinesidir ve sistem içinde sirküle edilen gaz olarak soğutucu akışkan R134a kullanılmıştır. Sistemin COP değeri farklı çalışma koşullarında hesaplanmış ve elde edilen sonuçlar tümüyle tartışılmıştır. Bu doğrultuda, ısı pompasının her elemanındaki entalpi değişimi farklı çalışma koşullarında hesaplanmış ve P-h diyagramı üzerinde ele alınmıştır. Bu çalışma, sistem performansının doğru bir şekilde tahmin edilebilmesi için cihaz kurulumundan önce dikkate alınabilecek ısı pompaları, soğutma makineleri ve buzdolapları alanında pratik çözüm yöntemi olan bir simülasyon yöntemi sunmaktadır.
