Domestic Refrigeration Trainer PC- Engineering Lab Training Systems Description and Specifications for Lab Tenders
Domestic Refrigeration Trainer PC- Engineering Lab Training Systems.
Technical Description
The system
demonstrates the operation of a compression refrigeration unit. A
closed, insulated chamber is cooled using a refrigeration circuit
comprising a compressor, condenser, evaporator and capillary tube. A
special feature is the ability to enlarge the heat exchange area of the
condenser by switching in a 2nd stage. It is possible to use the unit to
simulate faults.
The intake and delivery pressure of the
compressor are indicated on pressure gauges with an additional
temperature scale for the refrigerant and recorded using pressure
transducers. Temperature sensors measure the relevant temperatures.
Their values are indicated on a digital display with selector switch. A
further switchable display indicates the voltage, current and power
consumption of the compressor. At the same time, the measured data can
be displayed and processed on a PC. A data acquisition card with
appropriate software is included.
