Abstract

Plug-in refrigerated display cabinets are widely used in supermarkets. Since these cabinets do not have a drainage system connected to the mains, the accumulated defrost water is removed with the help of PTC resistance. The energy consumption of the PTC resistor constitutes nearly 20% of the total energy consumption. Considering that the final energy consumption is met from primary energy sources; With the decrease in fossil fuels and the increase in energy costs, it is necessary to use the consumed energy more efficiently. In this study, the refrigerant in superheated vapor state at the compressor outlet was passed through the compressor discharge line pipes and the stagnant water in the condensation pan. By adding additional fins to the discharge pipes in the condensation pan, heat transfer is increased and energy consumption is reduced. In this way, the energy consumption of the cabinet was reduced, and the energy class, which was "E" in the current system, was upgraded to the "D" class with the new design. Thus, an environmentally friendly design has been introduced and 11,138 kg/day CO2 emissions for 1 refrigerator have been reduced by reducing primary energy consumption.

Özet

Süpermarketlerde teşhir tipi plug-in soğutucular yaygın olarak kullanılmaktadır. Bu soğutucularda şebekeye bağlı drenaj sistemi bulunmadığından, biriken defrost suyu PTC rezistans yardımı ile uzaklaştırılmaktadır. PTC rezistansının enerji tüketimi toplam enerji tüketiminin yaklaşık %20’sini oluşturmaktadır. Nihai enerji tüketiminin birincil enerji kaynaklarından karşılandığı düşünüldüğünde; fosil yakıtların azalması ve enerji maliyetlerinin artması ile tüketilen enerjinin daha verimli kullanılması gerekmektedir. Bu çalışmada, kompresör çıkışında kızgın buhar halindeki soğutucu akışkan kompresör basma hattı boruları ile defrost kabında bulunan durgun su içerisinden geçirilmiştir. Defrost kabı içerisinde bulunan basma borularına ilave kanatçıklar eklenerek ısı transferi artırılmış ve enerji tüketimi azaltılmıştır. Bu sayede soğutucunun enerji tüketimi azaltılarak mevcut sistemde “E” olan enerji sınıfı yeni tasarım ile “D” sınıfına yükseltilmiştir. Böylece çevre dostu bir tasarım ortaya koyulmuş ve birincil enerji tüketimi düşürülerek 1 adet soğutucu için 11,138 kg/gün CO2 emisyonu azaltılmıştır.
