If you compress a gas, it gets hotter through a process called adiabatic heating. It gets even hotter because the compressor is not a perfect machine and will add heat to it. It you take the compressed gas and let it cool to ambient temperature by passing the hot compressed gas through a radiator and then let it return to ambient pressure you will get adiabatic cooling. If this now cooled gas was compressed again and cooled again you could make it colder and colder. A process like this is used to make liquid oxygen.
Special refrigerant gasses are usually used so that when they are compressed they become a hot liquid that is then cooled. This is then allowed to evaporate through a small hole. Not only does this mean you get adiabatic cooling but there is more energy absorbed to enable the change of state from liquid to gas, or latent heat of evaporation.

What plant do they use when making ice cream?

Why is salt sprinkled to the ice in ice cream?
To lower freezing point, making the ice cream mix in the container colder than freezing temperature so it freezes faster. Its much easier to make ice cream with a compressor freezer than a salt & ice freezer.

Why is my fridge making loud sounds?
Your fridge may be making loud sounds due to a few common reasons, such as a malfunctioning fan or compressor, ice buildup, or loose components. It is important to have a professional technician inspect and repair the fridge to prevent further damage.
Why is salt added to ice when you're making homemade ice cream in an ice cream freezer.?
Salt acts as an antifreeze, reducing the melting/freezing point of the ice. This makes the salt & ice freezing mixture much colder than that of ordinary ice, causing the ice cream to freeze faster and with smaller crystals. An ice cream with smaller crystals feels smoother and creamier in the mouth.I use a compressor ice cream maker, which requires no salt & ice mixture as it has a built in electric powered freezer.
