SPECIFICATION

  • Complete refrigeration system enabling demonstration of the vapor-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 evaporator— 2x Electronic sensors measuring pressures before and after the compressor— 2x Bourdon type refrigeration pressure gauges (with scale indicating equivalent refrigerant saturation temperature)— lx Variable area flowmeter measuring refrigerant flowrate— lx 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
