R134a for Low temperatures
Hi all,
I have a question regarding use of R134a in a freezer. The compressor manufacturer's specs indicate a lowest evap temp (-) 35°C. At this temp, the suction pressure will be at something like 9 psia or about (-) 6 psig. Is there any problem with a system that operates at such low pressures in the long run ?? Can somebody throw light on this ??
