1. Presentation on “ RECHARGING CUM RECYCLING OF REFRIGERANT GAS: AN INNOVATIVE APPROACH ” Presented by Swapnil N Meshram Jotiram Kapane Haridas Sultane

2. INTRODUCTION Global warming is the major problem faced by human in today's era. CFC elimination Recover as much of refrigerant Usually comprising a hermetic compressor, air-cooled condenser and filters.

4. RECOVERY OF REFREGERENT

5. REMOVAL OF A REFRIGERANT FROM A SYSTEM AND THE PLACEMENT OF THAT REFRIGERANT INTO A CONTAINER.

6. REFRIGERANT RECLAMATION INVOLVES PURIFYING USED REFRIGERANT

7. “ MULTI-PURPOSE GAS RECOVERY MACHINE ”

8. CONSTRUCTION & WORKING

10. WORKING comprises basic three functions Recovery Charging Vacuuming

11. OIL SEPARATOR Compressor oil Recovery Towards the Condenser High pressure High temperature Refrigerant Filterer

12. DISTILATOR. Refrigerant from Oil separator Towards the condenser Compressor Inlet From the refrigeration System Waste oil

13. For charging with Recovery machine Sr. No. Equipment Quantity Recovered (80% of actual) Quantity of Refrigerant used Cost of Refrigerant used Energy Required (Wh) Energy Cost (Rs.) Total cost (Rs.) 1Refrigerator0.32kg0.0848420.1448.14 2AC1.2kg0.3300840.29300.29 3Car AC1.44kg0.36360900.36360.36

14. ADVANTAGES Control Global warming to some extent Reduced cost Provide future scope for small sector

15. DISADVANTAGES Not reliable as a commercially manufactured unit. If liquid refrigerant enters the machine the compressor may probably fail.

16. CONCLUSION allows recovery of various refrigerants provides better control on global warming reduces the maintenance cost of various refrigeration and air conditioning systems ¾ th cost of equipment no alternative gut to get rid of them for the sake of our future generations. Diameter of tubing is optimized from 9.5mm to 7.6mm.
