A "degree day" is a unit of measure for recording how hot or how cold it has been over a 24-hour period. The number of degree days applied to any particular day of the week is determined by calculating the mean temperature for the day and then comparing the mean temperature to a base value of 65 degrees F. (The "mean" temperature is calculated by adding together the high for the day and the ...Based on NOAA records, the year 2019 holds the record for the most 90 °F days in Atlanta history. There were 91 days with a high temperature of at least 90 degrees that year. How many so far this year (2024)? It has not reached 90 degrees Fahrenheit in Atlanta so far in 2024. As of May 19, the highest temperature this year is 87 °F.The perfect refrigerant reading depends on several factors, like atmospheric pressure and temperature. I like to see an average range of 58-85 PSI on the low side and 120-300 PSI on the high side. These indicate that the unit is running okay and should be cooling properly. TL;DR: R22 is almost phased out and even banned.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 ...A regular efficiency condensing unit will condense at ambient plus 30F degrees, so at 95 F outdoors we can expect about a 125 F condensing temperature which converts in R 22 to about 270. Indoor 80F air enters a 40 F evap coil for a 20 F degree Delta T or temperature differential, about 10 degrees super-heat a foot after the coil on the suction ...

what should be the normal reading on hi and low side on a 95 degree day. ... I would expect a low side of roughly 70 PSI, and an hi-side pressure of roughly 20-30 above outside ambient temperature (depending on efficiency of unit) which would correspond to 243-278 PSI. ... You will see that low a liquid line reading on heat pumps which usually ...

The best answer is—as usual—whatever the manufacturer says it should be. If you really NEED a general answer, you can generally expect: High Temp or A/C systems to run 6-14°F of superheat. Medium Temp - 5-10°F. Low Temp - 4-10°F. Some ice machines and other specialty refrigeration may be as low as 3°F of superheat.In this case, this pressure (46 psig) will correspond to a temperature of 23 degrees, which is 15 degrees cooler than the lowest desired box temperature of 38 degrees. If the pressure control has a high event (cut-in) and a differential setting, the cut-in will be set at 68 psig and the differential will be set at 22 psig (68 psig - 46 psig).75 80 85 90 95 100 105 110 115 Cooling Pressure (PSI) @ Service Port (Tolerance +/‐5) Outdoor Temp (°F) Refrigerant Pressure vs. Temperature Charts for Pioneer Split Systems (R410a) 68 115 119 123 127 131 135 139 143 147 71 120 124 128 132 136 140 ...R22 changes from a liquid to a gas in the evaporator coils of the air handler.
