Abstract - In this task we have designed and analyzed a
excessive depletion if ozone layer (ODP) and Global Warming Potential (GWP). The use of LPG as an alternative of CFC 22 has made a higher development due to the fact that it has an surroundings pleasant orientation with no ODP. Good product effectivity is resulted by way of the use of LPG due to the fact of its characteristics. Thus we have to look at these two kinds of refrigerants (LPG and CFC 22) in a modified home fridge evaluating their overall performance traits parameters like pressure, temperature etc. in fridge and thinking about security whilst conducting the realistic experiment. It shows LPG can be used as an choice refrigerant to CFC 22 after performing the check on new system.
fridge the use of LPG as refrigerant. As the strain of LPG is excessive this saved in cylinder. As this pressurised LPG is exceeded thru the capillary tube of small interior diameter, the strain of LPG is diminished due to enlargement and segment alternate of LPG takes place in an isenthalpic process. Due to segment alternate from liquid to fuel latent warmth of evaporation is won via the liquid refrigerant and the temperature decreased. In this way LPG can produce refrigerating impact in the surrounding. From experimental investigations, we have observed that the COP of a LPG Refrigerator is greater than a home refrigerator.

COP, Vapour Compression Refrigeration system, Refrigerating Effect.
1) To become aware of the shape of residual waste in normal refrigeration system.
1. INTRODUCTION
2) Compare the essential traits between LPG refrigeration machine and ordinary refrigeration system.
Due to the big demand of electrical energy over the world, we assume of improving the electricity which is already spent however now not being utilized further, to overcome this crisis with much less investment. The climatic alternate and international warming demand on hand and low-priced cooling structures in the shape of fridges and air conditioners. Annually Billions of greenbacks are spent in serving this purpose. Hence forth, we recommend COST FREE Cooling Systems. LPG is saved in liquefied nation in cylinder earlier than its utilization as fuel. According to the power survey, the fridge is one of the heaviest electricity buyers amongst family appliances. The electricity consumption of fridges has accelerated step by step yr over year. It works on the precept that the growth of LPG will be takes area all through the conversion of liquid LPG into gaseous form. As a end result of this, LPG fuel strain drops and the quantity of gasoline will be enlarge this will be end result into dropped in temperature of gasoline and it acts as refrigerant. According to 2d regulation of thermodynamics, this system of cooling can solely be performed with the useful resource of some external work. Hence, the energy grant is typically required to force a refrigerator.
3) To distinguish between the cutting-edge current fridge fee and estimated fee of LPG refrigerator. 4) The overall performance of present fridge and LPG fridge is to be compared.
2. EXPERIMENTAL SETUP 2.1 Working Principle The LPG Refrigerator is work on the easy Vapour Compression Refrigeration system. The building and working of easy VCRS is as proven in fig. 1 Process 2-3: When the compressor is started, it attracts the low stress vapor from the evaporator at country two and compresses it is entropically to a sufficiently to a excessive strain up to nation three Since the compression work is achieved on the vapour, its temp additionally increases Process 1: Hot vapour from compressor below strain is discharged into the condenser the place condenser cooling medium normally water or surrounding air is soak up the warmth from warm vapour. This converts the warm vapour into liquid and the liquid is accumulated in liquid receiver at State 4.
The substance which works In a fridge to extract warmness from a bloodless physique and to supply it to a warm physique i.e.to surrounding is known as refrigerant. Globally 17500 metric lots of traditional refrigerants is ate up through home refrigeration like CFC, HFC which motives
