產品簡介
  The Refrigeration System Trainer provides students with intermediate-level instruction in refrigeration systems through the use of industrial devices. Equipped with a 1/2-hpemi-hermetic compressor, the unit also contains a forced-air condenser and twin forced-air evaporators that can be used individually or linked in a series. An interconnected schematic panel enables students to work individually or in pairs to perform simultaneous measurements at the main board or at the panel. Instrumentation includes a digital temperature meter; ampere, volt, and watt meters; pressure gauges; and system function lights.
Fully integrated courseware guides students through alternative modes of system set-up and control. Eighteen faults can be introduced into the system to help students develop troubleshooting skills.
產品特色
