BRINE REFRIGERATION EQUIPMENT

Brine is an antifreeze heat-carrying medium that is cooled by a refrigerant through an evaporator and transfers the cooling effect to the object to be cooled.
Using a refrigeration system based on a brine circuit, the cooling performance of the target object can be identified in real time according to the concentration of brine used as a secondary coolant, enabling experiments for measuring freezing performance.
This equipment is designed to standardize, miniaturize, and expose complex, large-scale, and conventionally concealed ice storage refrigeration systems and automatic control panels, allowing easy access for experimental practitioners.
Students can enhance practical skills through integrated experiments, including the configuration of ice storage refrigeration systems, the design and implementation of automatic control circuits required for system operation.
