Operating an air conditioner for extended periods of time in low temperatures outdoors lowers the suction pressure to a velocity where the oil will not return to the compressor and will run dry. Also, under low ambient conditions “indoors” does not provide sufficient load to change refrigerant from a liquid to a 100% vapor.An essential tool for charging 410A by subcooling is a set of HVAC gauges. These gauges allow you to measure the pressure in your system, helping you determine the correct refrigerant charge. Make sure to use gauges specifically designed for use with 410A refrigerant.

As shown in Figure 1 on the next page, the same unit will operate under the same conditions with a suction pressure of 118 psi and a discharge pressure of 400 psi with R-410A. HFC-32 and HFC-125 are mixed together in R-410A, which is an azeotropic mixture.Suction Pressure / EVAP DTD Rule of Thumb Another common old school rule of thumb is suction pressure should be close to the outdoor temperature in an R22 system. However, this rule of thumb (obviously) does not work on an R-410A system. A more applicable guideline is 20˚-25˚ suction saturation below outdoor ambient.• Protected compressor - Compressors are protected internally by a high pressure relief valve and a temperature sensor, and externally by the system high and low pressure …The pressure of R-410A is so high that if your hand gets in the way of a leak, it could cut a finger off.

But in an R-410A system, the suction pressure drop can be allowed to go as high as 3.1 psi before the same losses in performance are seen.OPERATING PRESSURE POINTS “Systems using R-410A operate at higher pressures [than R-22],” points out the Field Diagnostics team. “For example, to produce an evaporating temperature of 40 degrees F and a condensing temperature of 115 degrees, the suction and head pressures would be 83 psia and 257 psia in an R-22 system, while they would be 133 and 406 psia, respectively, in an R-410A ...

The higher pressure, and the fact that R-410A performs very much like a single component refrigerant, provide an opportunity to produce a more compact system with greater efficiency. In addition, R-410A refrigerant allows more suction line pressure drop since it is less sensitive to suction line efficiency losses.Refrigerant Type R-410A R-410A R-410A R-410A R-410A R-410A R-410A Refrigerant Charge (limit) lbs 13 13 13 17 17 17 17 Oil Type Trane OIL00079 (qt)/OIL00080 (gal) Oil Charge oz 101 101 101 88 112 112 112 Suction Fitting Connection Brazed Brazed Brazed Brazed Brazed Brazed Brazed Suction Fitting (ODF) in 1.125 1.125 1.125 1.375 1.375 1.375 1.375the heat content of the return air (including the sensible temperature) drops, the saturated suction temperature will drop, resulting in a drop in suction pressure.
