Product Description

MODEL OF A REFRIGERATION SYSTEM WITH REFRIGERATION AND FREEZING STAGE

The HSI training system for refrigeration and air conditioning technology. In combination with the base unit the operational model of a refrigeration system with refrigeration and freezing stage results. The model is plugged onto the base unit, secured using fasteners and connected with refrigerant hoses to become a complete refrigeration circuit.

In refrigeration and freezing combinations evaporators are preferably connected in parallel. To increase the refrigeration capacity, evaporators are operated connected in series. Here different pressure levels in the evaporators can be used to obtain different temperature ranges for refrigeration or freezing. Two separate refrigeration chambers with evaporator and expansion elements.

The operation of individual system components, here temperature control, fan, heater, compressor and solenoid valves, takes place via the software. The software offers the option to simulate faults. Temperatures and pressures in the system are recorded by sensors and displayed dynamically in the software. The effect of parameter changes can be tracked online in the log p-h diagram. Fundamentals and individual components are represented in the educational software for ET 915.02. Performance assessments check the learning progress. With the aid of the

authoring system further exercises and performance assessments can be created.
