A crucial component of a car's air conditioning system , its function is to regulate the amount of refrigerant gas (Freon) entering the evaporator , converting it from a high-pressure liquid to a low-pressure vapor to begin the actual cooling.
Air conditioner refrigerator valve specifications:
- Country of Origin: Korea
- Product Brand: HANON
- Product Number: 97604-1C100
- Compatible Models: Hyundai Accent (2003-2005)
⚙️ Main function:
- The pressure of the freon coming from the air conditioner radiator is reduced .
- It regulates the amount of Freon entering the refrigerator according to the air conditioner radiator temperature and the required cooling amount.
- Maintains refrigerant balance within the A/C circuit to prevent freezing or loss.
💡 It works based on the change in temperature and pressure , through an internal sensor and a thermal medium.
❄️ Signs of a damaged or blocked expansion valve:
Poor cooling despite Freon charging due to a blocked or faulty valve
Frozen pipes due to excessive valve opening
Difference in cooling temperatures due to poor thermal response
A "whistling" sound inside the dashboard due to pressure leaking through the valve.
