High Efficiency R-134a Compressor for Domestic Refrigerator

Because of high growth in economy and rapid increase in energy consumption , the government has made efforts to resolve the difficulties of the shortage of energy by restricting the amount of electrical energy consumption for home electrical products and several products consuming energy. Especially, the rules specified how the amount of electrical energy consumption was tested is expected to revise since 1996,and so the situation in grade expressed the efficient consumption of energy has been developed unfavorably since the electrical energy consumption per month was measured more 30% in amount than that used to be when testing the amount of electrical energy consumption for the same model of a refrigerator in according to the revised rules. INTRODUCTION In general, a compressor which consists of the heart of a refrigerator, a heater which removes frost,and a fan-motor which can distribute chill equally are considered as the main causes of consumption input in a refrigerator. Among the above components, improving the energy efficiency ratio of a compressor that has occupied 80 through 85 percent of the total electrical energy can decrease the amount of electrical energy consumption for a refrigerator. Therefore, we want to specify the studied and developed results about the high efficiency of the reciprocating type of a compressor for R-134a. HOW TO PROGRESS C.O.P (Coefficient of performance) In general, in order to progress the efficient of a compressor for a refrigerator, each element such as volume efficiency, compression efficiency,mechanical efficiency and motor efficiency shall be improved. In order to achieve the high efficiency of a compressor as the above specified contents, the cooling capacity shall be increased and the consumption input shall be decreased. So, we can make the cooling capacity be enhanced up to 15% and E. E. R be enhanced up to 9% in contrast with the existing R-12 model by selecting the items which the high efficient effects are anticipated and handling theory with experimental data together on the basis of the above specified theory.
