Sustainability of Automobile Air- Conditioning System Using Refrigerant R1234yf Instead of R134a

sustainability of automobile air- conditioning system using refrigerant r1234yf instead of r134a

air conditioning refrigerant r134a has value of global warming potential (gwp) 1300, which is much higher than mac directive (gwp below 150) passed in july 2006. this prompted a search for alternative refrigerant with gwp value less than 150. r1234yf is a new refrigerant which has lower gwp value of 4. effect of blower speed has been compared and flammability issue of r1234yf has been addressed...

Selection of Refrigerant for Air Conditioning System Using MCDM-TOPSIS Approach

The Air conditioning system satisfies the various space conditions required for the comfort and industrial air conditioning. Now days demand for AC system applications are increasing and include the areas of application like apartment buildings, banks, office buildings, industrial plants, schools, restaurants etc. This growing demand for air conditioning system forced manufactures to develop su...

Experimental and Analytical Investigation of Automotive Ejector Air-Conditioning Cycles Using Low-Pressure Refrigerants

In recent years, ejectors have received much attention because of their ability to reduce throttling losses and increase the efficiency of stationary and mobile air-conditioning systems. While much of the initial research was carried out with high pressure fluids, such as carbon dioxide, it was soon discovered that ejectors can also offer significant advantages in systems that utilize low press...

Effect of Using Evaporative Condenser Instead of Air Condenser in Window-air Conditioners

In this paper,&#10 the application of evaporative cooling for refrigeration cycle to reduce power consumption in hot climates is emphasized. Experimental and analytical investigations were performed in order to specify the effect of evaporative cooling condenser instead of the commonly used air cooling condenser in window-air-conditioners. Evaporative condenser can reject more heat, thereby pre...
