The Test of Permeable by Expansion Valve in Cooling Compressor
Abstract
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 of the given incompatible respectively unwanted products.

Introduction
In the past the cooling was used in particular to cooling of food. At present, the demand for refrigeration technology is the much larger. Households use refrigeration not only for food storage but also in air conditioning units. In the chemical industry, refrigeration is used to extract rare gases. In the medical environment, cooling is an essential aspect of storing transfused blood. Mechanical engineering uses cooling in various work processes, such as cutting. Thanks to cooling, the performance of cutting tools up to 100%. This could be continued and mention many industries for which refrigeration is an integral part [1].
Conclusion
All results are processed in a capillary flow restriction report. It is developed a chemical control and work with wear analysis. In Fig. 5 shows a section through a capillary where the deposition of paraffin in the capillaries is affected and also the grey deposited dust, which may affect the life of the compressor.
The HFC test is designed to detect the effect of various components on cooling. Chemical reactions that occur during compression can cause it to fail. It is therefore necessary to ensure such conditions in the manufacture of the compressor that contamination of the internal parts of the compressor did not occur. It is very important to pay attention not only to the cleanliness of the plant, but also to work equipment and protective equipment, which should not have substances that can cause an undesirable chemical reaction with refrigeration or oil. The HFC test detects the amount of increasing impurities in the expansion valve and in the evaporator.
