Okay kiddo, have you ever gone inside a really hot room and felt uncomfortable because it was too warm? Or, on the other hand, have you ever been in a really cold room and felt like you needed a blanket to keep warm?
Well, sometimes people use special machines called air-conditioners and heaters to control the temperature in a room or building. These machines work by either cooling the air or heating it up.
The Air-Conditioning, Heating, and Refrigeration Institute (AHRI for short) is a group of companies that make and sell these machines. They work together to make sure all the machines are safe and work properly.
They also make refrigeration machines, which are used to keep food and drinks cold. Think about how ice cream is stored in a freezer at a grocery store- that's an example of refrigeration.
The machines that the AHRI makes are important because they help keep us comfortable in the summer and winter months and keep our food from going bad.
