Sep 19, 2019 · It has a better GWP (Global warming potential) of 550 than 1980 (GWP of R410A) It releases less CO2 than R410A. Some of the Cons : It is highly flammable, thus a suppressant of R125 (Pentafluoromethane) was added with R32 to form R410A. If safety is your concern, forget R32 and go with R410A.
R-410A systems operate at higher pressures than standard R-22 systems. Do not use R-22 service equipment or components on R-410A equipment. No other refrigerant may be used in this system.

Subcooling is part of a process used to remove heat from a designated area. The process works through the use of a liquid that is made to absorb heat from the area to be cooled. This liquid is referred to as a refrigerant. Like all liquids, this refrigerant can be converted to and from a gas by altering its temperature.

After it rejects enough heat, the refrigerant changes to a subcooled liquid. It is possible for the refrigerant to stay saturated instead of subcooling if the system is extremely low on refrigerant.

A liquid subcooling level of 15 F was maintained for all the test conditions. The tests showed that performance of these three lower-GWP alternative refrigerants is comparable to that of R-410A. For the 20 F superheat and 15 F subcooling test conditions, EERs of R32, DR-5, and L-41A were 90% to 99%, 96% to 99%, and 94% to 101%, respectively ...
For sale is one new slide type calculator used for calculating R 410A superheat and subcooling. This is a very useful tool that takes the guess work out of charging cooling systems. One side of this tool is a slide chart used for calculating superheat for a NON-TXV system and the other side is a slide chart used to calculate subcooling on a TXV ...
• Subcooling – The cooling of liquid refrigerant below its saturation temperature – Standard air-cooled systems are designed to operate with a minimum of 10°F of subcooling – High efficiency condensers operate with more subcooling than standard efficiency systems – Determined by subtracting the condenser saturation temperature from
† R-410A systems operate at approximately 60% higher pressures (1.6 times) than R-22 systems. Do not use R-22 service equipment or components on R-410A equipment. Use appropriate care when using this refrigerant. Failure to exercise care may result in equipment damage or personal injury. † Only match this outdoor unit with a matched indoor

R-410A is chlorine-free to help prevent damage to the ozone layer. The GSX16 features a high-efficiency Copeland® scroll compressor and is designed for the consumer who desires superior comfort, quiet operation, and environmentally friendly air conditioning performance. Suva® 410A is intended for use in new air condition-ing applications that have traditionally been serviced by HCFC-22. Many other applications are also possible such as medium and low temperature refrig-eration. Due to the significantly higher pressures that Suva® 410A exhibits compared to HCFC-22, a typical compressor designed for HCFC-22 cannot be used

Jun 24, 2020 · During air conditioning mode, the pressure on the vapor line of an R-410A system will be somewhere between 102 to 145 PSIG. If the system had R-22, the vapor pressure would be between 58 to 85 PSIG but these pressures will be dependent on the wet bulb temperature inside the building and the ambient temperature outside the building.

Subcooling (for units with Thermostatic Expansion Valve or TXV): Compute subcooling by determining saturated condensing temperature from Temperature Pressure Chart. Subtract from liquid temperature entering TXV. The manufactures recommended subcooling is usually listed on units rating plate. Mass flow rates through six EEVs were measured by varying the EEV opening, inlet and outlet pressures, and the subcooling. Mass flow rates of R410A were compared with those of R22 at the same test conditions. Based on the experimental data, an empirical correlation for mass flow predictions in EEVs was developed by modifying the orifice equation.
