by compressing freon as a gas it can be concentrated in one place where it can be condensed into liquid freon once again; in liquid form it can be evaporated as in the vapor/compression cycle of a mechanical refrigeration system absorbing heat as from the food in your fridge.
by applying pressure
Freon is a refrigerant that is in liquid form when inside a pressurized container. When the container is turned upside down, the liquid Freon will flow out first due to gravity. Once the pressure is released, the Freon can evaporate into a gas.

The purpose of conducting a gas pressure test is to check for leaks or faults in a gas system. It is performed by pressurizing the system with gas and monitoring for any drop in pressure, which could indicate a leak.
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.
This process is called condensation.
Purpose of a pressure regulator is to match the flow of gas through the regulator to the demand of gas placed upon the system. It is a valve that can automatically cut off the fluid of a liquid at a certain pressure.

If a substance can be easily compressed on applying pressure, it is likely in a gaseous state. Gases have particles that are far apart and move freely, allowing them to be compressed easily.
Applying heat to a gas will make it expand. If the volume of the gas is restricted (i.e. it cannot expand) then the pressure will increase.
R 134 is freon gas. In small amounts, the exposure to freon gas is not dangerous. In larger amounts, freon can cause respiratory issues.
