Question

If purging does not occur in a refrigerating system, what is the result?

A) High-head pressure
B) Low condense pressure
C) Low head pressure
D) All of the above

Answer 1

If purging does not occur in a refrigerating system, it can result in issues such as accumulation of moisture and contaminants, reduced efficiency, and increased energy consumption.

Step-by-step explanation:

If purging does not occur in a refrigerating system, it can result in several issues.

1. The first issue is that moisture and contaminants can accumulate in the system. Purging is essential for removing air, moisture, and non-condensable gases such as nitrogen and oxygen from the refrigeration system. If these substances are not removed, they can interfere with the operation of the system, leading to reduced performance and potential damage to components.
2. The second issue is that the system may experience reduced efficiency. Purging helps to maintain the proper balance of refrigerants and prevent the build-up of impurities. Without purging, the refrigerant may become contaminated, which can decrease its heat transfer capability and overall efficiency.
3. Lastly, the lack of purging can result in increased energy consumption. When contaminants and moisture accumulate in the system, the compressor has to work harder to achieve the desired cooling effect, leading to higher energy usage and increased electricity costs.

To ensure the proper functioning and efficiency of a refrigerating system, it is important to regularly perform purging to remove any air, moisture, or non-condensable gases.
