Refrigerant generally used in achieving - 80 deg C are R - 508 B / SUVA 95 in cascade type cooling system.
-80 degrees Celsius is equal to -112 degrees Fahrenheit.
That really depends on the type of refrgrant used it is going to a lot higher than it would be than if it was on a 70 degree day one you know the refregeerant used you can look at you thermal chart and then conduct your calculation. Tom Clark.
On a 90 degree day, the approximate pressure of an air conditioner unit can vary depending on factors such as the efficiency of the unit, the refrigerant used, and the specific operating conditions. However, typical operating pressures for a residential air conditioner on a hot day could range from 200 to 300 pounds per square inch (psi) on the high side and 60 to 80 psi on the low side.
The square root of -6400 is not a real number because the square root of a negative number is not defined in the real number system.
80 degrees Fahrenheit = 26.6666667 degrees Celsius
100 degrees Celsius minus 20 degrees Celsius is equal to 80 degrees Celsius.
80 minus 12.6 is 67.4
80 minus 4 is 76.
All devices used for refrigerant recovery must be certified by the EPA. If the device was manufactured before November, 1993, It must be capable of recovering 80% of the refrigerant in the appliance. If the device was manufactured after this date, it must be capable of recovering 90% of the refrigerant.
90 - 80 = 10
-80 - 1 = -81
80 - 45 = 35
140 - 80 = 60
5000.00 minus 20% = 80% of 5000.00 = 5000.00*80/100 = 4000.00
173 - 90 = 80
200
an A minus obviously ranges from an 80 to a 84 :D
