Can the freezer use water as a refrigerant?

Because water has the following advantages as a refrigerant:

The first one, water, is very cheap and very easy to obtain.

Compared with professional refrigerants such as R12, R22, and R134a, water is very cheap and easy to obtain. This is a feature of water as a refrigerant.

Second, the water will never explode.

As we all know, compared with ammonia-based refrigerants, R12 and other freon-based refrigerants have very low flammability and explosiveness, so they are very safe, but if water is used as a refrigerant, there is no possibility of explosion at all, so There is no doubt about safety. It can be said that if water is used as a refrigerant, it must be the safest refrigerant.

However, water as a refrigerant has certain restrictions. For example, the temperature of water as a refrigerant cannot be lower than zero degrees Celsius. If it is lower than zero degrees Celsius, it will reach the freezing point of water, so it cannot be lower than zero degrees Celsius. Freezer system provides service, refrigerant! The reason why water cannot be used in industrial refrigerators is because water cannot be used in compressors, whether it is a screw compressor or a piston compressor, water cannot operate normally in it.

The reason why water can’t operate normally in the compressor is because its specific volume is relatively large, so it cannot be used in the compressor. In the end, the evaporation pressure will be very low, and the normal operation of the refrigerator system cannot be guaranteed. There is no way for water to be normally used by compressed refrigerator systems.
