What type of vapor treatment is typically avoided in refrigeration systems?

Non-condensable vapors are typically avoided in refrigeration systems because they can severely impact the system's efficiency and operation.

In a refrigeration system, the presence of non-condensable gases (such as air or other gases that do not condense under the system's operating conditions) can lead to various issues. For one, they can create back pressure within the condenser, which raises the condenser temperature and pressure, ultimately reducing the system's ability to release heat effectively. This can prevent the refrigerant from condensing properly, thereby affecting the overall cooling performance.

Additionally, non-condensable vapors are generally not soluble in the refrigerant, meaning they will not be removed from the system through normal processes like condensation. This can lead to a buildup of these gases over time, further degrading system performance. Regular maintenance practices, including the evacuation of non-condensable gases, are essential to ensure the reliability and efficiency of refrigeration equipment.

In contrast, condensable vapors and refrigerant vapors are integral to the refrigeration process, and heating vapors typically refer to the process of the refrigerant absorbing heat, which is essential for the system to cool effectively.
