The working principle of chiller

Refrigerant is a substance that can evaporate at low temperature and condense at high temperature. Common ones include Freon, ammonia, methane, etc. Its working principle is to use the physical properties of refrigerant to complete the process of transferring and converting heat in the circulation system. It can absorb heat to cool the substance, or release the absorbed heat to increase the temperature.

Application of refrigerants in different fields

1. Refrigeration industry

Refrigerant is the most commonly used substance in the refrigeration industry, mainly used in air conditioners, refrigerators, cold storage, freezers and other equipment. In the refrigeration system, the refrigerant is compressed at high temperature and becomes a high-temperature and high-pressure gas. After flowing through the condenser, it will become a high-temperature and low-pressure liquid, evaporate in the evaporator, and absorb heat to complete the refrigeration process.

2. Industrial refrigeration

In addition to common refrigeration equipment, refrigerants are also widely used in the field of industrial refrigeration. For example, refrigerants can be used in low-temperature environments required during processing, such as cement production, agricultural product refrigeration, steel industry, petrochemical industry, pharmaceutical production and other fields.

3. Aerospace

Refrigerants are also widely used in the aerospace field. For example, astronauts need to live and work in a closed environment in space, and refrigerants can be used to maintain the temperature and humidity of the closed environment to ensure the health of astronauts.

4. Healthcare

Refrigerants are also used in the healthcare field. For example, refrigerants can be used to make refrigerators to refrigerate and freeze medical items such as vaccines and blood products.
