This module is part of the Hardware/Software Integration (HIS) training system for refrigeration and air conditioning technology. When used with the base unit IRC-1923, it forms a functional model of a domestic refrigerator. The module attaches securely to the base unit with fasteners and connects to refrigerant hoses to create a complete refrigeration circuit. The trainer includes a refrigeration chamber equipped with a heater for simulating cooling loads, an evaporator, a fan, and various expansion elements. The fan ensures even temperature distribution within the chamber, while the heater simulates additional cooling loads. Solenoid valves allow the system to operate either with a capillary tube or an expansion valve. All components are neatly organized on a panel. System components such as temperature control, fan, heater, compressor, and solenoid valves are managed through the software, which is optional. The software also offers fault simulation capabilities. Sensors monitor and record temperatures and pressures, which are displayed dynamically in the software. Changes in parameters can be tracked online using the ph diagram.
