Standard pressure of a refrigerator
Webb3 juli 2013 · The type of use (MBP/LBP) and the volume of the cold storage/freezer room are often used as rule of thumb, in order to perform a simplified calculation of the heat input coming through the walls and thus the refrigerating capacity. This calculation is sufficient in most cases. WebbIn the R134a, pressure can be determined at any temperature that ranges between -22 to 202 degrees Fahrenheit. This can be done by reading from the pressure-temperature chart on the refrigerator. Refrigerators using R134a refrigerants are designed to operate under …
