Why are water and brine the most common refrigerants for refrigerators?
One. Water and salt water are cheap.
As we all know, the price of water and salt water is basically the cheapest of the refrigerants, and as long as the refrigeration temperature is higher than 0 degrees Celsius, it will basically be used, below 0 degrees Celsius, as long as it is not too low temperature All chillers that can be above the freezing point of salt water will also use salt water. Water and salt are cheap and very suitable for small, medium and micro enterprises.
Two, water, salt water, easy to obtain.
Both water and salt water are relatively easy to obtain production materials, and therefore the price is relatively cheap. Therefore, compared to some special refrigerants, they are much cheaper and more suitable for use by some small enterprises, which can greatly reduce the burden on enterprises. And operating costs!
Three, non-toxic, relatively safe.
Neither water nor salt water has any toxicity, so relatively speaking, it is relatively safe. For some chemical refrigerants, water and salt water can be said to be harmless to humans and animals. Whether the refrigerant is harmful or not is normal for the enterprise. The operation still has a certain impact. If there is no special requirement, a Freon-type carrier refrigerant should be used for refrigeration!
