You can vent propane to … REFRIGERANT TEMPERATURE-PRESSURE CHART -- MOSTLY COMPUTER GENERATED FROM NIST REFPROP V5.10 Pressure (PSIG) Gauge (top row is temperature in deg F, negative numbers IN RED are inches of vacuum) Low-side pressure during normal operation of the same compressor model and refrigerant and the same outdoor air temperature of 85 °F called for 45 °F. h) Evaporation rate. d) pH. This would appear to be non-flammable and non toxic substitute for R-12 at extreme pressure ratios. SPECIFICATIONS Standard characteristics Limit values Appearance clear Vapor pressure at 20 °C 7,6 ± 0,2 bar Composition : propane isobutane n-butane C4 unsaturates ≥ 99,5 % volume The present experimental investigation based upon the study of ZnO nanoparticles in a vapour … ±0.03°C. Refrigerant Pressure Temperature Chart Harper Gallery. 10. at -25 °C evaporation the pressure is roughly 190 % of R134a, 81 % of R404A, 350 % of R600a or almost exactly that of R22. Common Refrigerants: Temperature / Pressure Charts (PDF 2.0 MB) Pressure & Temperature Data for Common Refrigerants (bar) Booklet (PDF 729.0 KB) Pressure & Temperature Data for Common Refrigerants (kPa) Booklet (PDF 733.0 KB) Temperature is a measure of how hot or cold an object is. At each of these locations, four PTIOOs were located at the top, sides and bottom of the tube to take care of any circumferential temperature variation. First, install the can tap valve and charging hose. Take precautions. f) Initial boiling point - 42 °C.
