Refrigeration equipment refers to a category of machinery used to lower and maintain the temperature of a space or object. It is widely used in areas such as food processing, cold chain logistics, medical storage, and industrial production. By utilizing principles of compression, condensation, and evaporation, refrigeration equipment removes heat from objects or spaces to achieve constant temperature, refrigeration, or freezing effects. Common types include refrigerators, freezers, cold storage rooms, and air conditioners, which effectively extend the shelf life of products, ensure product quality, and provide comfortable temperature control in high-temperature environments.
