The base unit can be extended into a full refrigeration circuit depending on the experiment’s objectives, using various available models such as the refrigerator module, a refrigeration system with both cooling and freezing stages, or an air conditioning module. Key components of this training system include the compressor, condenser, receiver, and both electrical and communication systems. The models attach to the base unit and connect hydraulically through refrigerant hoses and electrically with cables. Self-sealing couplings minimize refrigerant loss, and the components are arranged to be clearly visible for monitoring their operation. The system includes advanced software integrated with the hardware for ease of experimentation and analysis. The experimental unit connects to a PC via USB or LAN. The software includes a system operation and data acquisition program, as well as educational software that aids understanding with explanations and illustrations. Each model has a specific software module tailored to its learning objectives, and teachers can create additional exercises using an authoring system. Sensors measure temperatures and pressures, which the software displays in real-time for both system operation and data acquisition. The software provides precise data on the refrigerant’s condition, allowing for accurate calculations of refrigerant mass flow rate. This method of calculation is more precise than traditional measurement techniques. The software also tracks the effects of parameter changes in a log p-h diagram and optionally allows system operation through the software.
