I. Overview

1, Adopt the transparent material, mold shape once, intuitive is strong, help to teaching.

2, Overall appearance, reasonable design, simulation, small volume.

3, Refrigeration system and heating system are equipped with multistage protection measures, to ensure the safe and reliable operation.

4, Refrigeration system adopted the copper material, efficiency, long service life.

5, Comprehensive functions, can refrigeration and heating, and has simulation demonstration system, and all of the fault setting.

6, It has the computer interface, easy to remote control experiment equipment working condition and collecting several relevant data.

II. Equipment configuration

The main components characteristics and working principle:

1, compressor: system adopt totally closed piston compressor, normal working temperature is only 0 ℃, safe and reliable, compact structure, low noise, good sealing, refrigerant R22 for.

2, evaporator: refrigeration system uses transparent tank evaporators, easy to observe, be clear at a glance, evaporator group dip in water, preparations in the tube evaporation, the water in the water pump on the function of the flow in the tank, in order to enhance cooling effect.
