The Refrigeration and Cryogenics winter school deals with the methods and technologies of obtaining below ambient temperatures. Refrigeration includes technologies used in such popular devices as domestic refrigerators and freezers, air conditioners or heat pumps, but also in industrial installations with high cooling capacity, e.g. in food processing. Some specialised refrigeration devices can reach temperatures as low as -80oC. Cryogenics comprise the methods of obtaining the temperatures below 120K (-153oC), down to a mile Kelvin above absolute zero. It provides a permanent gas liquefaction technology, economical storage and transport of large amounts of gases, e.g. LNG, high-capacity gas mixtures separation or thermal stabilisation of the superconducting devices. The winter school introduces a theoretical and practical knowledge on how to lower the temperature of a different objects or how to handle substances with extremely low temperature. It covers selected issues related to design of heat pumps, methods of natural cooling, calculation of cryogenic cycles, or heat transfer at cryogenic temperatures
