Will the Evaporator Pressor Regulating valve close if the Thermostatic Expansion Valve is in the evaporator air stream?

The EPR valve should work reguardless of if the TXV is in the air stream. The TXV in the airflow shouldn't make it act any different since it is sensing the temperature at the bulb instead of at the valve it's self.

Effect of moisture on thermostatic expansion valve?
None, a TXV operates by it's sensing bulb sensing superheat of the suction line as it exits the evaporator coil.
What is the difference between the dry or direct expansion type of evaporator to the Flooded type evaporator?
Evaporator is said to be flooded type if liquid refrigerant covers the entire heat transfer surface. This type of evaporator uses a float type of expansion valve. An evaporator is called dry type when a portion of the evaporator is used for superheating the refrigerant vapour after its evaporation.
When the load on the evaporator increases the TXV?
when the load increases the amount of vapor increases , so the pressure inside the evaporator increases and as we r in the wet region inside the evaporator the pressure and the temp. are proportional so the temp. too will increase but we use some valves to fix this problem , for example thermostatic expansion valve it helps add more m dot of the refrigerant so the amount of heat from the load will be distributed over a larger mass so the pressure inside the evaporator will remain the same
Can use 7 ton condenser unit hook up the 6 ton evaporator?
you can probably get away with that just make sure you have an expansion valve on the evaporator. An expansion valve will keep liquid from getting back to the compressor.
What role does a compessor play in a refrigeration system?
In vapour compressor refrigeration system the low pressure and temperature vapour refrigerant from evaporator is compressed. where it is compressed to a high pressure and temperature. From compressor refrigerant goes to condenser where where it changes the phase. from condenser refrigerant goes to evaporator through expansion device.
What advantage does a capillary tube have over a thermostatic expansion valve.?
Thermostatic expansion valve allows more refrigerant into the evaporator coil during a hot pulldown it allows the evaporator to reach peak performance faster

Which component cosists of a thermal sensing element used to regulate the flow of liquid refrigerant into an evaporator?
Thermostatic Expansion Valve
Dry expansion 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.

How do you replace ac evaporator on 2001 elantra?
CAUTION: Some models are equipped with anti-theft-radio make sure you have the activation code before disconnecting battery * Have the AC system discharged * Disconnect negative battery cable * Working from the engine compartment side of the firewall,disconnect the air conditioning lines from the evaporator inlet and outlet pipes. * Inside the car,remove the dash * Remove the glove box supportbracket * Disconnect the thermostatic switch electrical connector and then diconnect the vacuum line between the door and the heater unit * Remove the upper and lower evaporator case mounting bolts * Remove the evaporator unit from the car * Remove the sponge pad which insulates the evaporator inlet and outlet pipes * Cut the foam that lines the opening on both sides of the evaporator case.Unclip the upper and lower evaporator cases and then separate the upper case from the lower case * Detach the thermostatic switch from the evaporator case and detach the thermistor mounting clip from the evaporator unit,and then remove the thermostatic switch and the thermistor as a single assembly * Remove the evaporator unit from the lower case and then remove the expansion valve assemby from the evaporator

What is a direct expansion evaporator?
Refrigerant enters a direct expansion evaporator as a saturated liquid vapor mix and leaves as a superheated vapor.
