Oil separator is NOT required in refrigeration system if: a)Refrigeran...
Explanation:

Oil separator is a device that is used in refrigeration systems to separate oil from the refrigerant. The oil separator is required because the refrigerant and oil tend to mix during the refrigeration process. The oil separator prevents the oil from circulating with the refrigerant, and it ensures that the refrigerant is clean and free from oil.

The correct answer is option 'B'. The oil separator is not required in the refrigeration system if the refrigerant and oil are immiscible at condensation pressure and temperature.

Immiscibility refers to the inability of two substances to mix completely. In the case of refrigerant and oil, immiscibility means that the oil and refrigerant will not mix completely and will form separate layers.

When the refrigerant is condensed, the temperature and pressure are at their highest. If the refrigerant and oil are immiscible at this point, it means that they will not mix during the refrigeration process. Therefore, an oil separator is not required in this case.

Conclusion:

In summary, an oil separator is required in refrigeration systems to separate oil from the refrigerant. However, if the refrigerant and oil are immiscible at condensation pressure and temperature, an oil separator is not required.
