Applications for R-401B are in normally lower temperature R-12 refrigeration locations and in transport refrigeration, and in R-500 as a direct expansion refrigerant in air-conditioning systems. This was on the top brands. R32 refrigerant (difluoromethane (CH2F2)) has long been used as a component in R410A. R32 is also more energy efficient than R410A. Refrigerant R410A is the much better refrigerant in the market to use as it is environment friendly and contains less harm relatively other refrigerants. 2. As the refrigerant leaves the evaporator, the refrigerant has to be in 100 % vapour form, to avoid ingress of liquid refrigerant inside compressor as the liquid is incompressible. R-410A cylinders are colored rose. To find longer-term alternatives, it is necessary to move to R32 HFO blends or R717, all of which require significant system re-design. In every instance, the halide torch test are carried out in a well-ventilated room. High suction gas density at the compressor suction means low sized compressor and a lesser-powered compressor motor. Ammonia has a lesser density compared to air, so in case of any leakage, ammonia mixes into the atmosphere. Avoid moisture formation by connecting a filter drier which absorbs moisture from the refrigerant. The replacements of the CFC and HCFC refrigerants are the HFC’s. R404a Ozone depleting potential = 0 and Global Warming Potential = 3260. The presence of moisture in lubricating oil may deteriorate properties of lubricating oil and formation of metallic or other sludge which may lead to clogging or chocking of valves, filters, and other oil passages. The cooling properties of R32 is similar to that of R410a. R410A Refrigerant is widely used as a refrigerant in many air conditioning applications, usually packaged in rose colour cylinders. Given that refrigerant properties have a profound influence on refrigeration component design and system performance, Table 1 lists selected thermo-physical properties of R404a and R410a in comparison with R22 under typical operation conditions for medium temperature refrigeration applications. all these properties make R32 a promising choice for the present.
