Study of Efficient Cargo Area Grocery Refrigeration System in car by using alternate refrigerant R-12 and R-134a

When a vehicle is exposed to sun loads or high ambient temperature for a prolonged period of time both the passenger comportment and the cargo storage area become excessively hot. while most heating venting and air conditioning (HVAC) system can provide rapid cool down of passenger compartment temperature that is comfortable for the human occupant the cooling of the human occupants of the cargo storage are doesn't hamper. At that time the groceries, perishables and vegetables would be damage due to high temperature so it is necessary to protect these perishables a refrigeration unit must be create in the vehicle. In this article, Investigate Performance of Alternative refrigerant R-12 and R-134a in refrigeration unit of automobile vehicle, experimentally and theoretically By Different conditions refrigeration effect at static, dynamic state of vehicle have been tested.
