Non-condensables in a refrigeration system

Explanation:

Non-condensable in a refrigeration system will result in a higher discharge pressure.

Non-condensables are gases that cannot be condensed into a liquid form within the refrigeration system. These gases accumulate in the system and can cause an increase in the discharge pressure.

This is because, unlike the refrigerant gases, non-condensables do not condense into a liquid in the condenser, leading to a higher pressure in the system.
