An evaporator valve, often referred to as an expansion valve, is a critical component in refrigeration and air conditioning systems. It regulates the flow of refrigerant into the evaporator coil, allowing for efficient heat exchange and cooling. By controlling the refrigerant's pressure and temperature, the valve ensures optimal system performance and energy efficiency. It can be either thermostatic or electronic, depending on the system design.
It is attached to the back wall of evaporator. You have to remove the glove compartment, blower unit and evaporator to get access to the expansion valve.
You must remove the evaporator case from behind the glovebox and disassemble it. The expansion valve is mounted to the evaporator.
In dray expansion evaporator, the liquid refrigerant is generally fed by an expansion valve. the expansion valve controls the rate of flow of refrigerant to the evaporator. In the evaporator the liquid refrigerant is vaporized and superheated by the time it reaches to the end of evaporator. At inlet of the evaporator, the refrigerant is predominantly in the liquid form with a small amount of vapor formed as a result of flashing at the expansion valve. the liquid refrigerant passes through the evaporator, more and more refrigerant is vaporized by the load. according to the load, the liquid will come into evaporator and vaporize and reaches to superheat at the end of the evaporator. The inside of the evaporator is far from dry but wetted with liquid so named as dry expansion evaporator.
The evaporator valve is located in the HVAC housing on a 2005 Dodge Ram 1500. The housing is located behind the dash.
The expansion valve is located in the lines connecting the evaporator core which is located inside the evaporator housing behind the dash and the glove box.
If you are talking about the expansion valve then its located on the evaporator ...............
An externally equalized thermal expansion valve is used to regulate the flow of refrigerant into the evaporator based on the evaporator's temperature. By sensing the refrigerant pressure at the outlet of the evaporator, the valve can adjust the flow rate to maintain proper superheat levels, ensuring efficient cooling performance in the system.
The pressure in a refrigeration system changes in the compressor, condenser, expansion valve, and evaporator. In the compressor, the pressure increases, while in the condenser, it remains high before decreasing in the expansion valve and evaporator.
the expansion valve is connected to the evaporator under the dash, have fun!!!
The expansion valve in an AC system is typically located between the condenser and the evaporator. It is usually found in the indoor unit, near the evaporator coil, or in the refrigerant line connecting the two components. This valve regulates the flow of refrigerant into the evaporator, allowing it to expand and absorb heat from the indoor air.
The orfice tube is located in the evaporator inlet tube. There is also an expansion valve in the rear evaporator case.
Front a/c valve is in the line to the evaporator core, and the rear a/c valve is connected to the line of the rear evaporator core behind the left panel air intake behind the rear seat.
