Refrigeration refers to the mechanical process of removing heat from a space or substance to lower and maintain its temperature below ambient conditions. It is widely used in residential, commercial, and industrial applications, including food storage, HVAC systems, pharmaceutical preservation, and process cooling.
Refrigeration systems typically include components such as compressors, evaporators, condensers, and expansion devices, working together to circulate refrigerant and achieve efficient thermal control. In design and engineering, refrigeration layouts are essential for planning equipment placement, piping routes, ventilation, and system capacity requirements.
