The Test of Permeable by Expansion Valve in Cooling Compressor by Engineering Journal- IJOER - Issuu

Current article describes the HFC test, which the measure the amount of impurity in cooling compressors, which they could cause damage to them. In introduce of the article describes the process of cooling cycle in cooling equipment. In the tab. 1 are summarized the basic advantages and disadvantages of use natural based refrigerant, which are used in producing the compressors designated for equipment's as refrigerators, air conditions, cooling rooms. In the article are describe the media, which it may occur in compressor, but their presence can may cause the problems with the operation of compressor possibly its damage. We say about media respectively the products, which they are not miscible with oil. It is water, paraffin, silicone and alkali products. Test HFC discovers and measurements the presence these components and on the basis of their quantity decides on the quality of production of refrigeration compressors. The article describes the test procedure and in the end the evaluation of the maximum value
