REFRIGERANT TABLESTHIS SECTION IS DEVOTED ONLY TO QUALIFIED TECHNICIANS THAT KNOW THE FOLLOWING:THE OPERATIONAL PRINCIPLES OF THE REFRIGERATING CIRCUIT OPERATIONTHE MODES OF DETECTING TEMPERATURE AND PRESSURETHE RISKS RELEVANT TO THESE OPERATIONSThe data of the tables allow the testing of the refrigerating circuit operation by the detection of a few objective parameters.The data are significant if they are detected simultaneously and while the refrigerating circuit is running.OVERHEATING=return temperature – Saturation temperatureSUBCOOLING=condensing temperature (pressure *) – liquid temperatureReturn pressure 7.2 bar Condensing pressure 29.6 barReturn temperature 7.3 °C Liquid temp. 45 °Coverheating 7.3 – 0.8 = 6.5 °C subcooling 49.91 – 45 = 4.91 °C* It is important that the condensation pressure is detected as close as possible to the point where the liquid temperature isdetected, in the event that the calculation will be effected by the losses of charge (and, therefore, of temperature) causedby the refrigerating circuit components placed between the two measurement points.Pg = P gauge = relevant pressure (read on the pressure gauge) , Ts : saturation pressureFor R410A the glide was not considered, since it is close to 0Pg Ts [°C] Pg Ts [°C] Pg Ts [°C] Pg Ts [°C] Pg Ts [°C] Pg Ts [°C] Pg Ts [°C] Pg Ts [°C] Pg Ts [°C]0.0 -51.66 5.0 -8.69 10.0 10.42 15.0 23.74 20.0 34.22 25.0 42.95 30.0 50.47 35.0 57.10 40.0 63.020.2 -48.02 5.2 -7.73 10.2 11.03 15.2 24.20 20.2 34.59 25.2 43.27 30.2 50.75 35.2 57.35 40.2 63.250.4 -44.83 5.4 -6.79 10.4 11.63 15.4 24.66 20.4 34.97 25.4 43.59 30.4 51.03 35.4 57.60 40.4 63.470.6 -41.98 5.6 -5.87 10.6 12.23 15.6 25.12 20.6 35.34 25.6 43.90 30.6 51.31 35.6 57.85 40.6 63.690.8 -39.40 5.8 -4.97 10.8 12.82 15.8 25.57 20.8 35.71 25.8 44.22 30.8 51.59 35.8 58.09 40.8 63.921.0 -37.03 6.0 -4.10 11.0 13.40 16.0 26.01 21.0 36.08 26.0 44.53 31.0 51.86 36.0 58.34 41.0 64.141.2 -34.84 6.2 -3.24 11.2 13.97 16.2 26.46 21.2 36.44 26.2 44.85 31.2 52.14 36.2 58.58 41.2 64.361.4 -32.81 6.4 -2.40 11.4 14.54 16.4 26.90 21.4 36.81 26.4 45.16 31.4 52.41 36.4 58.82 41.4 64.581.6 -30.90 6.6 -1.57 11.6 15.10 16.6 27.33 21.6 37.17 26.6 45.47 31.6 52.68 36.6 59.07 41.6 64.791.8 -29.10 6.8 -0.77 11.8 15.66 16.8 27.76 21.8 37.52 26.8 45.77 31.8 52.95 36.8 59.31 41.8 65.012.0 -27.39 7.0 0.02 12.0 16.20 17.0 28.19 22.0 37.88 27.0 46.08 32.0 53.22 37.0 59.55 42.0 65.222.2 -25.78 7.2 0.80 12.2 16.74 17.2 28.62 22.2 38.23 27.2 46.38 32.2 53.49 37.2 59.78 42.2 65.442.4 -24.24 7.4 1.56 12.4 17.28 17.4 29.04 22.4 38.58 27.4 46.69 32.4 53.75 37.4 60.02 42.4 65.652.6 -22.76 7.6 2.31 12.6 17.81 17.6 29.45 22.6 38.93 27.6 46.99 32.6 54.02 37.6 60.26 42.6 65.872.8 -21.35 7.8 3.05 12.8 18.33 17.8 29.87 22.8 39.28 27.8 47.28 32.8 54.28 37.8 60.50 42.8 66.083.0 -20.00 8.0 3.77 13.0 18.85 18.0 30.28 23.0 39.62 28.0 47.58 33.0 54.54 38.0 60.73 43.0 66.293.2 -18.69 8.2 4.48 13.2 19.36 18.2 30.69 23.2 39.96 28.2 47.88 33.2 54.80 38.2 60.96 43.2 66.503.4 -17.44 8.4 5.18 13.4 19.87 18.4 31.09 23.4 40.30 28.4 48.17 33.4 55.06 38.4 61.20 43.4 66.713.6 -16.22 8.6 5.87 13.6 20.37 18.6 31.49 23.6 40.64 28.6 48.46 33.6 55.32 38.6 61.43 43.6 66.923.8 -15.05 8.8 6.55 13.8 20.86 18.8 31.89 23.8 40.98 28.8 48.76 33.8 55.58 38.8 61.66 43.8 67.134.0 -13.91 9.0 7.22 14.0 21.36 19.0 32.28 24.0 41.31 29.0 49.05 34.0 55.84 39.0 61.894.2 -12.81 9.2 7.88 14.2 21.84 19.2 32.68 24.2 41.64 29.2 49.33 34.2 56.09 39.2 62.124.4 -11.74 9.4 8.53 14.4 22.32 19.4 33.07 24.4 41.97 29.4 49.62 34.4 56.34 39.4 62.354.6 -10.69 9.6 9.16 14.6 22.80 19.6 33.45 24.6 42.30 29.6 49.91 34.6 56.60 39.6 62.574.8 -9.68 9.8 9.79 14.8 23.27 19.8 33.84 24.8 42.62 29.8 50.19 34.8 56.85 39.8 62.80M03Y40D9-01 09/04/10 page 39
