HC system basics
Dear all,
I am sure that this thread is very basic for the HC experts but since I have no experience in this field, I would like to start this thread for myself and others who are like me .
As HCs are growing in our industry therefore, I think it is something we need to learn.
Can anyone explain :
1- Major difference with DX system with HCFC,...
2- Design differences
3- Equipment differences
4- Safety issues
And anything you think a beginner must know.
Again forgive me if this is very simple for you guys.
Appreciate your help.
Cheers

Re: HC system basics
Working with hydrocarbons should be based on several design assumptions to meet.
- The fluids are refrigerant grade. Various lighter components can separate and act as non-condensable vapor.
- The electrical systems/wiring are per code (usually explosion-proof.
- The proper oil is selected. Hydrocarbons tend to thin out the oils and result in loss of adequate lubrication/viscosity.
- The proper materials of construction are used. Non-sparking on external rotating devices (fans, couplings, etc.)
Other than these, it's just a refrigeration system.If all else fails, ask for help.
