refrigerating machine

A refrigerating machine is a device that removes heat from a specific area to lower its temperature, creating a cooling effect. It operates on the principles of thermodynamics, using a refrigerant that absorbs heat inside the machine and releases it outside. Common examples include refrigerators and air conditioners. These machines typically involve four main processes: compression, condensation, expansion, and evaporation, which circulate the refrigerant and enable cooling. Ultimately, refrigerating machines are essential in preserving food, providing comfort in living spaces, and supporting various industrial processes.
