Thermostatic Expansion Valve Operation:

Pressure changes in the evaporator:
- While pressure changes do play a role in the operation of the thermostatic expansion valve, it is not the main aspect responsible.

Temperature changes in the evaporator:
- The temperature changes in the evaporator are important as they help regulate the flow of refrigerant through the valve. However, this is not the primary factor.

Degree of superheat in the evaporator:
- The degree of superheat in the evaporator is the most important aspect responsible for the operation of a thermostatic expansion valve. Superheat is the temperature of the refrigerant vapor above its saturation temperature. The valve operates based on the superheat in the evaporator to ensure that the refrigerant entering the compressor is in a state that will not harm the compressor.

Degree of under cooling in the evaporator:
- Under cooling is the temperature difference between the liquid refrigerant leaving the condenser and its saturation temperature. While under cooling does affect the operation of the refrigeration cycle, it is not directly responsible for the operation of the thermostatic expansion valve.

In conclusion, the degree of superheat in the evaporator is the key aspect responsible for the operation of a thermostatic expansion valve. It helps regulate the flow of refrigerant and ensures that the system operates efficiently and effectively.
