Tenders Description & Specification for HSI Training System Refrigeration and Air Conditioning Technology, Base Unit
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.
The main components of compressor, condenser and receiver plus electrical and communications systems. The models are plugged onto the base unit and connected hydraulically with refrigerant hoses and electrically with cables. Self-sealing couplings reduce the refrigerant loss to a minimum. All components are arranged well visible to allow their operation to be monitored.
Temperatures and pressures in the system are recorded by sensors and displayed dynamically in the software for system operation and data acquisition. The refrigerant mass flow rate is calculated in the software from the recorded measured values. 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 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. Each model has its own software matching the learning objectives. With the aid of an authoring system, the teacher can create further exercises.
