Description

The Refrigeration Training System is a compact training system designed to teach the fundamentals of refrigeration. It demonstrates the operation of typical refrigeration systems using industrial and commercial devices.

The compactness of the training system allows its placement on a table or a bench, reducing the floor space requirements. Featuring the latest versions of refrigerant and components available on the market, the training system ensures up-to-date training. It also integrates instrumentation and process control components, as well as an electrical control panel. Instructors can insert faults to teach troubleshooting.

The training system features a powerful data acquisition system whose tools enable students to easily monitor operating conditions in real-time to provide key information, simplifying system troubleshooting and performance analysis.

Features & Benefits

  • Compact design allows the trainer to be mounted on a table or bench
  • Cooling chamber with clear acrylic door enclosing a forcedair evaporator
  • Commercial condensing unit using R134a refrigerant
  • Air-forced condenser with variable speed fan
  • Thermostatic expansion valve and two capillary tubes of differing lengths to compare the coefficients of performance obtained with different metering devices
  • Capillary tube metering devices
  • Electronic Pressure control with LCD display
  • Thermostatic Control. Pressure control
  • Heat load simulation
  • Seven thermocouple transducers and three pressure transducers used to acquire data at the critical points of the system
  • Conditioning of the compressor voltage and current
  • Lockable fault insertion switch
  • Circuit breaker and safety pressure switch
  • High-pressure safety switch with manual reset breaker
  • Estimated program duration: 25 hours
  • Integrates a powerful data acquisition system – LVHVAC software – for real-time monitoring
