Description & Specifications
Vapour Compression Refrigeration Unit
Technical Specification
Fully instrumented to enable complete analysis of the processes involved
and calculation of the changes in performance with operating
conditions. Computer controlled system with automatic recording of
process variables using an integral USB interface. Hermetically sealed
rotary compressor driven by DC motor with three phase BLDC variable
speed drive. Complete refrigeration system enabling demonstration of the
vapour compression refrigeration cycle. Energy transferred to the
evaporator and from the condenser measured independently on the service
side of the process. Compressor speed under computer control with a wide
range of operation from 2000 to 4400 RPM. Real time display of
superheat calculations. Real time display of Coefficient of Performance.
Features:-
• Computer controlled with automatic recording of measured and calculated variables using a PC.
• Hermetically sealed rotary compressor with wide speed range can be varied by the operator.
• Complete system enabling demonstration of the vapour compression refrigeration cycle.
• Condenser and evaporator both use plate heat exchangers with
water as the heat transfer medium enabling a full energy balance to be
carried out while varying the operating conditions on both sides of the
compressor.
• Overall performance of the system is calculated and displayed
continuously enabling the effect of changes in the system to be
evaluated.
• Instrumented with electronic sensors measuring temperatures
throughout the process, pressure on both sides of the compressor and
independent water flowrates through the condenser and evaporator.
• Bourdon type gauges indicate the pressure and corresponding
refrigerant saturation temperature on both sides of the compressor
independent from the electronic systems.
• Variable speed pumps supply water at stable temperature and
pressure from a large reservoir to the condenser and evaporator
eliminating random fluctuations.
