HSI TRAINING SYSTEM REFRIGERATION AND AIR CONDITIONING TECHNOLOGY, BASE UNIT
The base unit is, dependent on the objective of the experiment, extended into complete refrigeration circuit with one of the models available as accessories refrigerator, refrigeration system with refrigeration and freezing stage, simple air conditioning system, air conditioning).
All components are arranged well visible to allow their operation to be monitored. The modern and powerful software is an integral part of the training system in the form of hardware/software integration (HSI). It enables the comfortable execution and analysis of the experiments. The experimental unit is connected to the PC via a USB interface.
The software consists of a software for system operation and for data acquisition and an educational software. With explanatory texts and illustrations the educational software significantly aids the understanding of the theoretical principles. With the aid of an authoring system, the teacher can create further exercises. Each model has its own software matching the learning objectives.
Temperatures and pressures in the system are recorded by sensors and displayed dynamically in the software for system operation and data acquisition. The effect of parameter changes can be tracked in log p-h and h-x diagrams. The system is also operated via the software.
The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments. The unit shall perform the following experiments and investigations:
