pressure. A platinum resistance thermometer is attached to the sample bombs for the temperature measurement. Temperatures are reported on the ITS-90, after conversions from the original calibration on the IPTS-68 are made. Pressures are measured with an oscillating quartz crystal pressure transducer with a (0 to 20) MPa range. AdiabaticIt worked good until Saturday. It was not cooling the house. 90 deg outside. Temp got up to 78 inside while set on 72. It would normally maintain 72 no problem. Air at vents was still 60 degrees and had good air flow going through new filter and blowing out vents, but house was still not cooling. Unit was making a funny noise.So if it's 85º out the saturation pressure in the system (that's been sitting off) should be 255 psi for 410a. If it's much different than that, then you would want to treat it as contaminated refrigerant when recovering. I assume 5 below would mean 80º in this example to account for the indoor coil being colder, so 236 psi.Critical Pressure 714.50 psia (4926.1 kPa [abs]) Critical Density 30.52 lb/ft3 (488.90 kg/m3) Critical Volume 0.0328 ft3/lb (0.00205 m3/kg) Units and Factors t = temperature in °F T = temperature in °R = °F + 459.67 P = pressure in lb/in 2 absolute (psia) vf = volume of saturated liquid in ft 3/lb vg = volume of saturated vapor in ft 3/lb
