Overview: Cooling System Design, Continued
The evaporation temperature of the R134a coolant is minus 26 degrees Celsius at normal pressure (1 bar). Danfoss quotes an operating temperature of - 10 to - 35 degrees Celsius. - 35 degrees requires a vacuum of 0.5 bar. In theory, temperatures of up to minus 100 degrees are possible - given enough vacuum in the cooling system.
