In other words, refrigeration means artificial human-made cooling  . Heat is removed from a low-temperature reservoir and transferred to a high-temperature reservoir. The work of heat transfer is traditionally driven by mechanical means, but can also be driven by heat, magnetism , electricity , laser , or other means. Refrigeration has many applications, including, but not limited to: household refrigerators , industrial freezers , cryogenics , and air conditioning. Heat pumps may use the heat output of the refrigeration process, and also may be designed to be reversible, but are otherwise similar to air conditioning units. Refrigeration has had a large impact on industry, lifestyle, agriculture, and settlement patterns. The idea of preserving food dates back to at least the ancient Roman and Chinese empires.
