end of the evaporator on the suction line
oppisite side of txv sensing bulb on outlet of evaporator (suction line)
Difference between txv and exv.
None, a TXV operates by it's sensing bulb sensing superheat of the suction line as it exits the evaporator coil.
The purpose of the External equalizer on the TXV is to compensate for the pressure drop in the evaporator coil , This is done since the superheat calculation is based on the difference in the Saturation temperature corresponding to the Suction pressure (Measured after the coil) and the actual suction line temperature. Now, in a TXV measurement of actual line temperature is accomplished by using the Sensing Bulb and the Measurement of the Suction pressure by the External Equalizer of the TXV. The opening/Closing of the Expansion valve is controlled by the setting of the superheat which is governed by the setting of the Spring.
Unavoidable in certain situations. Light fixtures are sometimes mounted in the ceiling - the bulb must then be mounted base up or base horizontal.
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.
No, it is not.
change the bulb
Dual port TXV used when system need a large TXV for short periods of time. Dual-port valves have two independent capacities larger port for periods of high load smaller port for periods of normal load TXV capacity is doubled when larger port is open all the way.
spring
A TXV works as a metering device which senses the temp. of the suction line with a remote bulb as it gets warmer the diaphragm is de compressed to allow more fluid to flow through for cooling
You will need a new central mounted brake light bulb for your vehicle. Changing it is very easy. You just need to pull the old one out and push the new one in.
