Final answer:

The purpose of an externally equalized thermostatic expansion valve is to compensate for excessive evaporator pressure drop, allow for precise control of the refrigerant flow and superheat, and prevent the expansion valve from frosting up.


Explanation:

The purpose of an externally equalized thermostatic expansion valve in a refrigeration system is to:

  • Compensate for excessive evaporator pressure drop;
  • Allow for precise control of the refrigerant flow and superheat;
  • Prevent the expansion valve from frosting up.

This type of expansion valve helps maintain the efficiency and proper functioning of the system by regulating the flow of refrigerant based on the evaporator conditions.
