Description

Vapour Compression Refrigeration Unit

Specification:
  • Complete refrigeration system enabling demonstration of the vapour compression refrigeration cycle
  • 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
  • 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
  • Energy transferred to the evaporator and from the condenser measured independently on the service side of the process
  • Measurement sensors include:

– 9x Thermistor sensors measuring temperatures throughout the system – 2x Turbine type flow meters measuring flow of water through the condenser and e vaporator – 2x Electronic sensors measuring pressures before and after the compressor – 2x Bourdon type refrigeration pressure gauges (with scale indicating equivalent refrigerant saturation temperature) – 1x Variable area flowmeter measuring refrigerant flowrate – 1x DC Current shunt measuring current to the compressor motor

  • Supplied complete with large water reservoir to isolate the process from fluctuations in temperature or pressure in the mains water supply
  • Comprehensive instruction manual supplied
Features:
  • Complete system enabling demonstration of the vapour compression refrigeration cycle
  • 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
  • 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
