KR-101 Refrigerator Model Training System

KR-101 becomes a real refrigerator and students can use the meters located on the front panel to record the status of the components during its operation.

KR-101 also clearly demonstrates four major elements such as Condenser, Compressor, Evaporator, and Capillary Tube located at the rear side of the system.  Students can touch and feel the elements as well as draw the Mollier diagram to record the characteristic of the refrigerant during different phase of the refrigeration cycle.
 
For the sake of quick demonstration, KR-101 provides a Teacher Board for teacher to insert it into the side slot. When teacher board is inserted, the whole system starts running even the wire connections on the front panel are incorrect.


01. The major elements of the refrigeration system including condenser, compressor, evaporator, capillary tube, filter and drier are open for the purpose of best observation.
02. The system contains various electronic components and their symbols located at the front panel allowing students to use 4mm safety plug cables to construct the control circuit of the refrigeration system.
03. The control circuit of the refrigeration system are made of following electronic devices: system fuse, fan indicator, evaporator door switch...etc.
04. The system includes high pressure gauge, low pressure gauge, AC Voltmeter, AC Ammeter and temperature meter which are located at the front panel allowing students to record the status of the components during its operation.
05. The refrigerant path for high pressure tube is painted in red and low pressure tube in blue.  
06. Teacher board allows teacher to quick demonstrate the operation of the refrigeration system needless constructing the control circuits. 

01. Practical exercise for RSC wires of the compressor
02. Constructing the control circuit of the refrigerator system
03. Management of the refrigerator system
04. Characteristics of the refrigerator
05. Drawing Mollier Chart
06. Calculating the performance of the refrigerator
