R22 Substitutes

R22 Substitutes

 

In the past the R22 was considered to be the refrigerant with the most extensive distribution, the biggest number of different applications from heat pump applications and deep-freezing to air conditioning. Since the R22 refrigerant has been found out to have some ozone depletion potential it has been ruled out as being illegal to repair air conditioning systems that use the R22 refrigerant. It is the obligation of the contractors and workers to recommend to their clients to change over to the other refrigerants that are 100% non-ozone depleting in nature and also more productive than the R22. There are various replacements in the market and I have provided five of the R22 replacements that I believe are the better options available, learn more about them at http://www.bluonenergy.com/r22-replacement/. The following are some examples of the R22 Substitutes;

RS-44

This is an example of a drop-in refrigerant that can be a great replacement for the R22 especially in most systems which have a capillary and an expansion device. It is greatly compatible with alkyl benzene, POE oils, and also minerals.It has a lower temperature discharge which provides good operating benefits. It has lower head pressures and higher COP when compared to the R22.

R-404A
This alternative has a lower Global Warming Potential (GWP) than the R22. It also runs at lower pressures and can fix capacity issues in old systems. It has a higher saturation pressure for a given temperature than the R-22 does and will tend to run a cooler discharge temperature this in turn translates to greatly improve compressor life expectancy since the oil isn’t being cooked to the point of breaking down and slowly killing the compressor.  This replacement can be utilized because of its scope of uses in refrigeration hence it is classified as a substitute for an Original Equipment Manufacturer’s (OEM). It has a Coefficient of performance (COP) that resembles that of the R22, it also has a considerably lower temperature discharge than the R22 which in turn enables it to provide significant operating benefits like reducing the risk of oil degradation. It is suitable as a replacement since it is also nonflammable. This replacement is used in systems that have an expansion device in order for it to replace it at both lower and higher temperatures.

RS-52
It can be used as a “Drop-in” replacement. This refrigerant is greatly used as a substitute in a system or framework that is able to withstand high pressures. This replacement is suitable to flooded systems since it has a feature that enables while at lower temperature to have a higher capacity.

R507
By asking yourself what are some r22 substitutes we have to undertake a computation of the current refrigeration cycle when the plant’s retrofit. The R507 refrigerant demonstrates a propensity toward lower compressor end temperatures than the R22. This preferred standpoint can be used by introducing an internal heat exchanger. The relative loss of efficiency between the refrigeration cycles the R22 and the R507 can be decreased. In the meantime, the volumetric refrigerating limit is expanded when an internal heat exchanger is utilized.
