KR-105 Compressor Training System
Description
Trainees can wire the circuit of compressor personally using KR-105. Two start-up methods (current-mode and PTC) are provided in this training system. Trainees can measure and observe the signals on terminals in the start-up circuit to comprehend its operating principle. In addition, the trainer consists of a real refrigeration system. Hence, the start-up circuit can drive a real compressor when the wiring is completed. High / Low pressure gauges and voltage / current meters are embedded in front panel. The copper tubes in the system have reserved apertures for users to measure the temperature. Each component in the system is fixed individually. A transparent acrylic cover is assembled which can protect the components and make trainees observe the component’s structure clearly. Two fans are installed on the evaporator and the condenser respectively for adjusting evaporation and condensing conditions, which makes experiments diversified.
