The Freon refrigerant are non corrosive with all commonly used materials in the construction of refrigeration system such as brass, copper, zinc, iron, tin,lead & aluminium.However these refrigerants become acidic in presence of air and water. The solution at this concentration is known as “eutectic solution”.The lowest freezing temperature is achieved at eutectic point. (2) It is nonflammable and chemically stable with in the refrigerating system.
However it has the disadvantage of evaporator pressure falling below atmospheric pressure when used for very temperature application.
(5) Greater flexibility in simultaneously carrying cargoes at different temperatures in different cargo spaces is possible by controlling the amount of brine following to that space. Hunker may earn compensation through affiliate links in this story.
Kettering and Dr. Thomas Migley in the year 1928. (4)Open the cylinder valve and purge through the charging line with plenty of refrigerant. This refrigerant also has a distinct odor at higher concentrations so that when a device has chemical leaks, they can be quickly identified. is +30°C.The refrigerant should not react with lubricating oil as the lube oil gets exposed to refrigerant in the compressor. The theoretical values of C.O.P. Compressor has to be operated at high vacuum if the boiling point of the refrigerant is high at atmospheric pressure.Freezing point of the refrigerant is important because the refrigerant should not freeze under required evaporator temperature. The cost of the refrigerant is not very important in small units as the amount of refrigerant required for make up, in the event of leakage occurring in the system is small.The cost of the refrigerant, a high capacity refrigerating system is very important. (7) The ability of R-22 to absorb moisture is considerably greater than that of R-12 and therefore less trouble is experienced with freeze ups in R-22 systems. Low viscosity of the refrigerant in both states are desirable. The refrigerants from the family of hydrocarbon are highly flammable.The chemical reaction of the refrigerant on the materials used in the refrigeration system is not the prime consideration in the selection of the refrigerant, but the selected refrigerant decides the material to be used for construction of the system.The refrigerant must be chemically inert with the materials used for the refrigeration system.At the same time these materials must also be chemically inert in the presence of water or air. CHARACTERISTICS OF REFRIGERANTS Pure R-12 (CC 1425F425) is colorless. The solvent action of the refrigerant maintains the evaporator and condenser tubes relatively free of oil films which Otherwise would tend to reduce the heat transfer capacity of these units. The formed emulsion becomes effective when the percentage of water exceeds 0.01%. Low power consumption per ton of refrigeration is desirable. It presents an attractive alternative to current refrigerants especially in small capacity systems from operational safety point of View.Under many circumstances it is not desirable to carry the heat from the refrigerated space directly as refrigerant, than it is carried by using the secondary refrigerant.
The working substance that flows through a refrigerator and is capable of absorbing heat from the source ( which is at a lower temperature) and dissipate the same to the sink (which is a higher temperature than the source) either in the form of sensible heat (as in case of air refrigeration) or in the form of latent heat (as in the case of vapor Refrigeration) is called a refrigerant. The refrigerant should also not react chemically with the lubricants and other substances found in the refrigerator. The relatively cost of the three commonly used refrigerants are as follows:There is not a single best refrigerant which can be used for all refrigeration purpose. It is none toxic as well. fishing vessel. The refrigerant liquid condensed will be collected in the receiver, and here the quantity of refrigerant charged can normally be watched. (4) R-12 is oil miscible under all operating conditions and this not only simplifies the problem of oil return but also tends to increase the efficiency of the system. The freezing temperature of the brine is lower than the freezing temperature of water and it decreases with the increase of salt concentration but if concentration is increased beyond a certain point, the freezing temperature increases instead of decreasing. This property reduces the size of the pipeline required with R-22 compared to R-12(4) The pressure in the evaporator is above atmospheric for the evaporator temperature between -30°C to -40°C where as the evaporator pressure with R-12 are below atmospheric for this temperature range.
For example, in a regular home refrigerator, a Class A and Class 1 substance are used. operating at low temperature e.g. A dense fluid has less tendency to leak than a fluid with lesser density the possibilities of the leakage is more with high discharge pressure and low density refrigerant.The requirement of the H.P.
