Abstract

The use of heat pumps is increasing day by day. So, various refrigerants have been used in the heat pump systems so far. Therefore many studies and arrangements have been made to reduce the environmental effects of refrigerants. The refrigerant mixtures that obtaining from the hydrofluorocarbons (HFCs) and the hydrofluoroolefins (HFOs) are started to be used to reduce of global warming potential of the HFCs and remove flammability of the HFOs in these days. In this study, the performance of R134a/R1234yf (HFC/HFO) mixture in the heat pump was theoretically investigated for different R1234yf mass fractions (from 0.0 to 1.0). The analysis of R134a/R1234yf mixture for different R1234yf mass fraction has made for three different evaporator temperature (-10 oC, -5 oC and 0 oC) and a constant condenser temperature (35 oC). When the R1234yf mass fraction increases from 0.0 to 1.0 the COP value decreases by 2.44% (at the -5 oC evaporator temperature). The R1234yf mass fraction must be 0.9 for the R134a/R1234yf mixture to have lower GWP than 150. Because R134a is has high GWP.

Abstract

Isı pompalarının kullanımı gün geçtikçe artmaktadır. Bu nedenle, şimdiye kadar ısı pompası sistemlerinde çeşitli soğutucu akışkanlar kullanılmıştır. Bu yüzden, soğutucu akışkanların çevresel etkilerini azaltmak için birçok çalışma ve düzenleme yapılmıştır. Hidroflorokarbonlardan (HFC) ve hidrofloroolefinlerden (HFO) elde edilen soğutucu akışkan karışımları, HFC’larin küresel ısınma potansiyelini azaltmak ve HFO’lerin yanıcılığını gidermek için bu günlerde kullanılmaya başlanmıştır. Bu çalışmada, bir ısı pompasında R134a/R1234yf (HFC / HFO) karışımının performansı teorik olarak farklı R1234yf kütle karışım oranı (0.0 - 1.0) için araştırılmıştır. Farklı R1234yf kütle karışım oranı için R134a / R1234yf karışımının analizi, üç farklı evaporatör sıcaklığı (-10 oC, -5 oC ve 0 oC) ve sabit bir kondenser sıcaklığı (35 oC) için yapılmıştır. R1234yf kütle karışım oranı 0.0’dan 1.0'e yükseldiğinde, COP değeri % 2.44 azalmaktadır (-5 oC evaporatör sıcaklığında). R134a / R1234yf karışımının 150’den düşük GWP oranına sahip olması için R1234yf kütle karışım oranı 0.9 olmalıdır. Çünkü R134a yüksek GWP oranına sahiptir.
