Hello everybody

I am design engineer for propylene based refrigeration system which will be located in cold countries. Ambient temperature varies from -32 C to 44.8 C. can anybody tell about special precautions that we need to take care while designing refrigeration system for ambient conditions??

Hey.

Design systems with free cooling option. (saves a lot of power)
Heating element in compressors.
Control of condenser fans, for high enough condenser pressure at low outdoor temperatures.

Which company do you work for?

Regards
Kay

Thanks Kay for such a prompt reply

can you please advice me on the selection of motor for ambient conditions such as -32 C to 44.8 C?
and do we need steam tracing / electric tracing for lube oil system

You say that there is a propylene-based cooling system......
Is it a water cooled evaporator and air cooled condenser?
What temperature should you have on the water? 7/12 degrees?
I must know a little more about the system design to make recommendations, but maybe that it's a secret :-)
