Comparison of the advantages and disadvantages of common Freon refrigerants and liquid ammonia refrigerants
Research has found that there are only dozens of substances that can be used as refrigerants in the refrigeration industry, and only a dozen are commonly used in industrial refrigeration. Later, liquid ammonia and Freon were successively used. Currently, water is only used for jet and absorption refrigerants, and sulfur dioxide is used as a raw material for making dry ice. Sulfur dioxide and methyl chloride are almost in use now. At present, the refrigerants widely used in compression refrigerators are liquid ammonia and freon.
Liquid ammonia
Liquid ammonia is a refrigerant commonly used in industry. Its advantages are low boiling point, moderate pressure, large refrigerating capacity per unit volume, low throttling loss, dissolved water and leakage easily found, and low price. Liquid ammonia itself also has its unavoidable shortcomings: it is toxic, irritating, corrosive to copper and its alloys (except phosphor bronze) when in contact with water, can explode when mixed with air, and is easily volatile and decomposes at high temperatures.
Freon
Freon is a halogen derivative of saturated hydrocarbons. Their molecular formula is: CmHnFxIyBrz, and 2m +2u003dn+ The relationship of xo+y+z. Freon refrigerants are mostly non-toxic and odorless. It does not burn at the temperature of the refrigeration system, has no risk of explosion, and has good thermal stability. The large molecular weight of Freon has good wettability to metals. Its disadvantages are small refrigeration capacity per unit volume, large throttling loss, high specificity, and low thermal conductivity. It will decompose into toxic gas under flame stimulation, which is expensive. In recent years, scientific research has found that Freon has a strong damaging effect on the atmospheric ozone layer, which is an important cause of the greenhouse effect! The more commonly used Freon refrigerants are R12 (CF2Cl2), R22 (CHF2Cl2), and the relative coefficient of R12 to the greenhouse effect RGE is 1.0.
Which is better, Freon refrigerant or ammonia refrigerant?
Regarding this issue, Kuhua refrigeration experts will take your users to conduct a detailed comparison. Ammonia refrigeration system, as the name suggests, uses eucalyptus leaf to act as the refrigerant of the entire refrigeration system. Due to the low price of Aiye, the good volatilization temperature, and the relatively small daily maintenance costs, it is currently the most common refrigerant. The Freon refrigeration system uses services to act as a refrigerant. Compared with ammonia refrigerants, the cost of using Freon is higher, but the refrigeration effect is much higher than that of ammonia refrigerators, and its cost performance is quite high.
Secondly, the refrigeration piping of the Freon refrigeration system is quite complicated. Compared with the ammonia refrigeration system, the safety of use is the biggest advantage of the Freon refrigeration system. As we all know, ammonia refrigerant is quite easy to volatilize and diffuse. It has a strong pungent odor, which can damage the human respiratory tract and skin and mucous membranes, and cause certain damage to human health; especially when the ammonia concentration in the air reaches a certain level , It may also explode when exposed to an open flame, so strict leak prevention work must be done when using it.
