'''Refrigeration''' is the process of transferring heat energy from one location to another for the purpose of cooling an area. This process is modernly used in things such as [[refrigerator|refrigerators for food]] preservation and growth control, and air conditioning for reducing the temperature in buildings. This process goes against the natural process of heat energy flowing from hot to cold. | '''Refrigeration''' is the process of transferring heat energy from one location to another for the purpose of cooling an area.
