    2.7. Thermostatic Expansion Valve Thermostatic expansion valves are cooling system elements and have functions for the system to work correctly. They are connected to the evaporator inlet on liquid line. They enable that right amount of refrigerant is sent to the evaporator and lowers pressure, evaporation pressure and temperature of refrigerant. Thermostatic expansion valves enable to have a stable superheating degree at the evaporator.
