Model of a refrigeration system with refrigeration and freezing stage

Part of the HSI training system, this model creates a dual-stage refrigeration circuit when combined with the base unit. It features both refrigeration and freezing chambers to demonstrate multi-stage thermal management.

• dual refrigeration chambers with transparent fronts
• evaporators with recirculation fans and heaters for load generation
• adjustable evaporation pressure controller
• selectable expansion via valve or capillary tube
• system configuration via 5 solenoid valves
• software-based control and fault simulation
