We find in industry, that a large percentage of air conditioning systems are still running on R22, of course all of the new systems are now running with R410a. ... R410A saturated vapour pressure is approximately 60% higher than that of R22. The composition of the refrigerant and the increased pressures necessitate R410A dedicated tools and ...

very high condenser pressures compared to the R22 (R22: 43 °C, 15.8 bar; R410A: 42 °C, 26 bar) prevent the conversion of older sys-tems to R410A refrigerant. Because all components such as com-pressors, liquefiers, collectors, evaporators, piping, etc. must all be designed or developed to withstand these high pressures.R410A runs at a higher pressure than R22 does, so a system designed for R22 cannot use R410A. If you put R410A into an R22 system, then the compressor and other components could rupture – completely ruining the system. Another difference between the two refrigerants is that R410A is able to absorb more heat than R22 refrigerant.

When charging a refrigeration system, there are five main rules to follow: Rule 1. Always charge a receiver/sight glass/TXV system under a high evaporator heat load. This could mean simply opening the doors or putting an artificial or false heat load on the evaporator. Rule 2.

when the discharge-to-suction pressure differential exceeds 550 to 625 psid (38-43 bar). When the valve opens, hot discharge gas is routed back into the area of the motor overload to cause a trip. During fan failure testing, system behavior and operating pressures will depend on the type of refrigerant metering device.The R-410a is then run through an evaporator (heat exchanger) to cool down a cross-flow of warm air. The air is flowing at 0.121 kg/s and atmospheric pressure (100 kPa) and is cooled down from 300 K to 280 K at constant pressure. When the R-410a exits the evaporator, it is a vapor and has expanded to a pressure of 500 kPa (State 3). a.R-410A Pressure-temperature chart Click anywhere on this document to return to Refrigerant Gas Properties information at InspectApedia.com This chart was provided by the Bonneville Power Authority,i just installed a new split unit r-410a a/c system. it is running at 285/120 psig. the high side seems way low, should be about 420. the correct orifice is installed. this is a 1.5 ton condenser, 2 ton evaporator, and a 0.051 inch orifice. thanks for any suggestions. hvac.Refrigerant regulations are changing quickly at the state and federal levels, in order to facilitate a smooth transition away from R-410A to lower-GWP refrigerants.

Reply. 05-14-2013, 12:38 PM #7.Instagram:https://instagram. capitulo 8a 2 answers On the other hand, R-410A can handle more heat allowing the compressor to run cooler. The compressors used in new AC units are built to withstand greater pressure that is caused by R-410A refrigerant. Using this refrigerant in an AC that is designed for R22 can put too much pressure on the systems and that can lead to premature wear and tear. justin jefferson animated In contrast, R134A has been designed for smaller systems such as the automotive unit. R410A has a global warming potential of 1890, while R134A has a Global Warming Potential of 1340. Operating. R410A is a blend of two gases, R32 and R125.
