What is non Condensables?
Accordingly, what will non Condensables cause?
Non-condensables are always caused by improper system evacuation during an installation or repair. These poor procedures leave air, nitrogen, or moisture in the system. If a system has subcooling, superheat, and system pressures/temperatures that simply don't make sense, suspect that non-condensables are in the system.
Also Know, what is a non condensable gas? Non-Condensable Gas. A non-condensable gas is a gas that cannot be condensed under the process conditions, typically air, nitrogen, hydrogen, carbon dioxide, carbon monoxide or hydrogen sulphide.
Keeping this in view, how do I get rid of non Condensables?
The only way to remove non-condensables COMPLETELY in a small air conditioning or refrigeration system is to recover the entire charge and recharge with virgin refrigerant.
What effect do non condensable gases have on a refrigeration system?
Since air is composed mostly of nitrogen, a gas with a very low boiling point, it remains in the vapor phase throughout the refrigeration circuit, which means it does not condense. A non-condensable gas can adversely affect the system operation, reducing its energy efficiency and increasing the flow noise level.
