"On Chemical Refrigerants"
The art of refrigeration is related to people's livelihood and all aspects of industry. Among them, chemical refrigerants are the key elements of refrigeration, and their properties and uses are profound.
Chemical refrigerants, with their characteristics, absorb or release heat in the refrigeration cycle to achieve refrigeration work. Looking at their types, there are halogenated hydrocarbons, among which Freon was commonly used in the past, but it was gradually replaced by others because of its damage to the ozone layer. There are also ammonia, which has high refrigeration efficiency, but is toxic and flammable, so it must be used with caution. There are hydrocarbons, such as propane and butane, which are environmentally friendly and have a wide range of resources, but are flammable and need to be properly disposed of.
In Chemical Refrigerant Terms, the number of boiling points is of paramount importance. Low boiling point is easy to vaporize at room temperature, endothermic refrigeration; condensation temperature and pressure are related to its cycle efficiency and must be suitable for equipment design. And chemical stability cannot be ignored. If it is easy to decompose and react, it will be difficult to use it for a long time, and it may pose a risk of safety.
When using chemical refrigerants, the pros and cons must be weighed according to the specifications. Choose the right agent, with excellent equipment, and strict operation procedures to ensure the effectiveness of refrigeration, and protect the environment and ensure safety. In this way, the ability of chemical refrigerants must be well used for a long time.
