Why does refrigerant get cold when it expands?

When the Freon gas is compressed, its pressure rises, making it very hot. Next, the hot Freon gas moves through a series of coils, which has the effect of lowering its heat and converting it to liquid. The Freon liquid then flows through an expansion valve, which causes it to cool down until it evaporates.

What is the difference between a TXV and an Exv on a Subaru Sumo?

EEVs are top-of-the-line throttling devices. While TXVs are purely mechanical, EEVs can be programmed to work with the other components in the system, allowing it to further optimize performance and efficiency. While EEVs can outperform TXVs, the gains often do not justify the much higher cost.

Can an Subaru Sumo expansion valve get clogged?

If the expansion valve is stuck open or clogged, the AC system won't cool properly. A clogged valve leads to insufficient refrigerant, increasing the pressure in the system and causing the AC compressor to overheat.

Do cars have orifice tube and expansion valve?

An orifice tube is similar to an expansion valve, with both performing an important function in a vehicle's A/C system. The valve helps control the flow of refrigerant through the evaporator, which is the main cooling component of the system.

How do you replace the expansion valve on a Subaru Sumo?

Subaru Sumo 2.5; AC repair; expansion valve replacement. Once you take that 10 millimeter bolt off the 10 millimeter bolt you'll screw it into the the hole for the expansion valve and then you'll use that as a handle to pull the whole assembly out.
Subaru Sumo 2.5 - expansion valve replacement.

How do you test a TXV superheat on a Subaru Sumo?

Why Measure Both Superheat and Subcooling when Checking the. So superheat will be checked at the front of the evaporator coil. And since there's no port there we check all the way out here at the outdoor condenser.

What can cause low suction pressure on a Subaru Sumo?

Low suction pressure causes
  • The coil is covered with dust or frost
  • Restriction in the refrigerant line
  • Filters and strainers are dirty
  • Faulty fan motor
  • Low room temperature
  • Faulty compressor
  • Dampers are closed
  • Undersize of duct

What occurs when the operator takes control of the mode door while the system is in auto mode on a Subaru Sumo?

What occurs when the operator takes control of the mode door while the system is in auto mode? The system continues to control the blower and blend door and attempts to maintain the SET temperature.

What happens when expansion tank fails on a Subaru Sumo?

Oftenthe diaphragm dividing the two systems will fail, causing the two systems to become one. When this happens, the expansion tank turns into a "dead leg" that will eventually cause damage and premature failure to your water heater.

What are the symptoms of a bad TXV?

Bad TXV valve symptoms
  • There is frost on the evaporator
  • Your unit is blowing warm air
  • The AC compressor is running constantly

Comments on how to fix expansion valve on a Subaru Sumo:
I have an 02 325i and every time I turn my ac on my car wants to overheat please advise as to why.. It only happens with the AC. I changed my thermostat water pump and flushed the cooling system and my ac still causes my car to run hot and with the expaansion tank top off you would think I was boiling water on full blast. The coolant comes gushing out supper hot. But other than that my car runs fine with no problems.
Cool video, keep them up
amazing bro, errors are the way to success. thank you so much
Broku alan... Pasang extra fan boleh tambah sejuk ekon ke...tq
... pvc vent cover leaking. Also your cam covers. You should also check that tube and also the throttle body to see if there are any oil residues. If there is, more than likely your intake manifold is screwed.
Good video but its called refrigerant not freon. Read the can. People need to stop referring it as freon.
thank you so much, thanks is not enough
Well there is power but the flow of air is not there (blowing out of the vent
Terima Kasih Cikgu Alan... Alhamdulilah...
my mistake 04 gmc envoy
Bro hrga compressor yg tbaik brapa..
hi, i plan to change my 2010 suburban, do i need 2 expansion valve or it has only 1 expansion valve? could u give us the part number for the things u used?
Can I place the star contactor in the middle instead of delta contactor? If not, why?
Really enjoyed your video
Never introduce air into an AC system. It will take hours of evacuation to boil the moisture out. Any moisture left in the system will react with the refrigerant to form acid. This will shorten compressor life. A moisture analyzer should be used to check the system now.
Nice animation! Wish there is a narration to explain the difference between pink n orange color. Either colors, thermostat remains open to flow hot coolant to radiator to cool off. It is close only at initial start crank to warm up engine quickly, right?
Bos nak tnya klu econ kejap sejuk kejap panas apa masalahnya ye
Great video - Does anybody happen to know if this is the same process for a 2005 Hyundai Tucson. Was told this is the same vehicle.
Excellent video. At 9:27, how the 'coldness' can be stored and released later on? Thanks.
Appreciate the time you take to explain certain things
What were your symptoms? My front vents blow warm and me rear blows cold. Man i do miss my AC in my explorer. The heat got too hot and the ac got too cold.
