Refrigerants: Why Are They So Important?

We use refrigerant materials all the time. To cool our homes and to keep our perishables from going bad. A refrigerant is either a pure substance or a mixture of different materials, often a fluid of some kind, that is used in the refrigeration cycle. That is, it’s used to keep something cool (i.e. the air, food and drink, etc.). When it comes to running a compressor or HVAC unit efficiently, it takes a professional who understands not just the machinery but the materials, too.

Types of Refrigerants

There are many different refrigerant types. For instance, many hydrocarbons serve as coolants, as well as ammonia and even carbon dioxide. More specifically, there are three different classes of refrigerants. Class 1 substances cool by a physical phase change, usually confined to boiling. Class 2 coolants cool by a temperature change and the materials often include:


  • Alcohol
  • Calcium chloride brine
  • Sodium chloride brine

Class 3 materials contain solution vapors that can be liquefied. Many of these solutions can fall under several other categories. There is another system of classifying coolants which assigns each substance what is called an R-number, and that number identifies what specific elements make up that substance.
