Floating operating pressure
WebMay 20, 2012 · If you need a higher compression temperature, for instance in old buildings with cast-iron radiators, then you will need to choose a higher maximum working pressure. At 60°C the refrigerant R134a will be at an overpressure of around 16 bar, R407C (dew point) at 24 bar and R410A at 37.5 bar. WebMaybe you should follow the design codes for atmospheric tanks. Some examples are API 650, UL-142, EN-14015 or EN 1993-4-2. Read the scopes and decide the one that fits your needs.
