Freon itself if not cold. Freon can be used to cool things by compressing the gas and then letting it expand. When a gas expands, it cools down (for more information about that, look up the Ideal Gas Law). Freon is very effective for this purpose and because it is a gas with a high heat capacity. Any gas can cool thing in the same way, but Freon does it particularly well. Unfortunately it is what is called a CFC, which destroys ozone in the atmosphere.
Yes, Freon is toxic at certain levels. Overexposure causes central nervous system depression and possibly cardiac arrhythmia. Depending on the type of freon, it is also extremely cold and can cause severe burns if handled improperly.
I am working on my daughters but the first thing would be low on freon. Recharge it with a kit from AutoZone or similar store and ask them where the low side cap is. Read the directions on the can and just do it. If it takes freon, the can will get very cold and form frost.
Low on freon, a weak compressor, or a restriction in your metering device.
Freon under pressure, much like LP and butane are liquid. At sea level pressure, freon becomes a gas. For freon to work in a refrigeration system, it must be able to transform from liquid to gas to liquid. So, to fill a system, it must be put into that system in liquid form. To do this, the bottle containing freon must be tipped, otherwise only freon the gas would be expelled.
have the freon charge checked if the freon is low the evap core can freeze and the air flow is restricted and no air flow or little air flow is the result
Freon. In most of them nowadays, it is Freon 134-A.
Check freon charge.
Yes. Freon is for keeping the AC cold
There are a few reasons your AC might not get very cold even though the Freon is fine. You could have a leak in your line.
all i know is that freon is put into air conditioning units in your car. it's what causes your A/C to be cold
There is ice on the dehumidifier coil because it is low on freon. When there is not enough freon in a refrigeration system the inlet pressure to the compressor is lower than design due to lack of gas. Because it is at a low pressure the freon is very cold. This causes freeze-up. If You were to add freon to the running dehumidifier you would see the cold coil thaw, first at the end closest to the compressor suction and then work toward the other end of the coil. When the thaw reaches the other end of the cold coil it has enough freon and no more need be added. Tim Koller
Freon is an invisible gas and cannot be seen in the air. If Freon in leaking from a container in large enough amounts and is cold enough, you may notice the condensation of moisture due to the low temperature.
You coud be leaking freon. Or the level of freon in the car could be low or shot. Best thing to do is to go get it checked, and get it refilled. Freon is what makes the air cold. Not sure what type of freon your car requires. Some you have to have a license to use, others you can purchase at your local auto parts store. -Allen
Freon is the chemical that is used to make refrigerators and freezers cold. It is extremely dangerous if consumed or breathed in for long periods of time. The symptoms of Freon poisoning include dizziness, fainting, and headache.
When your air conditioning isn't cold
you would need to add freon
Look to see if the compressor is running when the ac is on. If not, then check the Freon pressure, as the compressor won't run if the Freon is low.
