They help to facilitate the change of higher pressure of liquid refrigerant in the unit to lower pressure gas refrigerant in the evaporator..
There is bulb which detects the temperature of the coil and is located at temperature within the evaporator..
the in the bulb will also increase hence pushing the spring to open the valve..
Similarly, the in the bulb will drop hence causing the spring to close the valve..
Depending on the capacity design of the system, the capillary tube diameter that is used range from 0.031″ to 0.065″ and the diameter from 0.083″ to 0.130″..
The high-side float is located at the high pressure side of the system and maintain constant level of refrigerant in the condenser.
