On quite a few systems, you can get your head pressure on the liquid line, but some systems may require you to connect to the discharge line to check the head pressure. A common rule of thumb is the 100-degrees over ambient rule; the temperature of the discharge line on ...#3 the reason you can't find anything on operating R-410A below 65° is there is no such rule. It makes no difference what type of refrigerant you have. It's all about the equipment that it's in. I know you don't want to hear it, but there's no reason why you could not have operated the thermostat at 40°F.PRESSURE CONTROLS COMPATIBLE WITH R-410A Control what’s important.

Though it can vary, the low side pressure of a mini split should not fall below 100 psi or raise beyond 160 psi. The working pressure of mini splits is depending on factors such as the weather and cooling load.Aug 9, 2009 · They recorded a 245 psi Head pressure and 115 suction pressure on my installation receipt. He also wrote "10 degrees subcool" on the receipt, which I don't see how that is possible when a 245 psi equals 83 degrees on an R-410a P/T chart. The small, copper liquid line (when measured near the compressor valve) doesn't seem to heat up much at all ...Come 2025, the Environmental Protection Agency (EPA) will set a 750 global warming potential (GWP) limit for air conditioning. This means that R-410A, with a GWP of 2,088, will no longer be able to be used in new equipment. So, what will it be replaced with? The most common low GWP alternatives are classified by ASHRAE as mildly flammable, or A2L.R-410A is a chlorine-free refrigerant that meets the U.S. EPA's newest, most stringent environmental guidelines. R-410A was developed as an alternative to R-22 (Freon), which will be phased out over the coming years in response to international environmental concerns. R-410A contains no chlorine, so it's not damaging to the atmosphere's ...When connecting gauges, connect to the always-suction port on the low side. On quite a few systems, you can get your head pressure on the liquid line, but some systems may require you to connect to the discharge line to check the head pressure. A common rule of thumb is the 100-degrees over ambient rule; the temperature of the discharge line on ...If the outdoor ambient is below 95°F optimally you should not feel any significant temperature rise above your hand temperature (97°). Put your hand in the airflow of the condenser (outdoor unit) fan, it should be not too hot and not too cool (normally a 30° temperature rise above ambient). Too hot is a dirty coil (even if it looks clean).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 downstream pressure of the test section was controlled by adjusting the temperature and flow rate of the hot water. Short tube restrictors and test conditions used in this study are listed in Table 1. The diameters of the tested short tube restrictors range from 1.10 to 1.80 mm with a fixed length of 12.70 mm.410a pressure. I installed a 410a, 2 ton condenser and coil today. The low side was 120 with 10 degree super heat, just like the manufacturer recommendations, but the high side was 475psi with 40 degree of subcooling. I felt like 475psi on a 80 degree outdoor temp was really high. Delta T was 14 indoor and the indoor wet bulb was …What should the 410a pressures on a 50, 65, 70 degree day be?
