The ideal refrigerant has good thermodynamic properties, is noncorrosive, and safe. The desired thermodynamic properties are a boiling point somewhat below the target temperature, a high heat of vaporization, a moderate density in liquid form, a relatively high density in gaseous form, and a high critical temperature. Since boiling point and gas density are affected by pressure, refrigerants may be made more suitable for a particular application by choice of operating pressure. Corrosion properties are a matter of materials compatibility with the components used for the compressor, piping, evaporator, and condenser. Safety considerations include toxicity and flammability.
Thermodynamics prop:
1: Low boiling point
2: Low freezing point
3: Critical temp of refrigerant should be high then the temp occurring with in the condenser.
4. latent heat should be desirable.
safe working property:
it includes:
>it should be chemically inert
>Should be non flammable, non toxic and non explosive.
>it should not react with lubricating oil
Physical property|:
1. should have low Specific volume
2. High thermal conductivity id required
3. Low specific heat of liquid refrigerant and high specific heat of vapour refrigerant are required.

Freon
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.

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.
No. You can loose volume and not cool as well, but as long as the amount of freon in a given system remains the same it will cool. The cooling properties come from the freon changing from liquid to gas and back again. It doesn't wear out.
R 134 is freon gas. In small amounts, the exposure to freon gas is not dangerous. In larger amounts, freon can cause respiratory issues.
Freon gas is used in refrigerators, air conditioners, ovens and all other types of these things.

Freon gas? Mostly r134a.
It could be any of the three but at room temperature it is a gas. Freon is a gas

Freon is a gas at room temperature and a liquid when cooled or compressed. Freon gas is colorless, non-flammable and relatively odorless. Some Freons have an ether-like odor.

Freon is a dangerous and deadly gas that can be fatal. However, the amount of Freon in a refrigerator is usually minimal, but it is still dangerous.
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
