Description
It is part of the HSI training system for refrigeration and
air conditioning technology. In combination with the base unit the operational
model of a domestic refrigerator is created. The model is plugged onto the base
unit, secured using fasteners and connected with refrigerant hoses to become a
complete refrigeration circuit. It consists of a refrigeration chamber with a
heater as cooling load, evaporator, fan and various expansion elements. The fan
supports the achievement of an even temperature distribution in the chamber. A
cooling load can additionally be simulated with the heater. Solenoid valves
enable the operation of the system with capillary tube or with expansion valve.
All components are clearly arranged on a panel. The operation of individual
system components, here the temperature control, fan, heater, compressor and
solenoid valves, takes place via the software. The software offers the option
to simulate faults.
Learning Objectives/Experiments
Design and operation of a simple refrigeration system
Different expansion elements
Operation with capillary tube
Operation with expansion valve
Operating behaviour under load
Refrigeration cycle in the log p-h diagram
Fault simulation
Features
Simple model of a domestic refrigerator for connection to
the HSI Training System Refrigeration And Air Conditioning Unit
Component operation and fault simulation via the software
Specification
Model of a refrigerator to plug onto the base unit
