The design and assembly of refrigeration training system (AR-027) introduces trainees to a type of refrigerators used for storing fruits and vegetables. This trainer allows trainees to assemble this type of refrigerator starting from designing the refrigeration cycle till building the whole refrigeration system of the refrigerator and allows them to acquire hands-on skills such as pipe bending, flaring and soldering. The training system includes all refrigeration components, equipment and tools necessary for assemble the refrigerator such as a complete set of workshop tools and equipment needs for pipes bending, flaring and soldering
- The training system demonstrates a commercial type of refrigerators that is used for storing fruits and vegetables to be fully assembled by trainees to gain practical skills of assembling and maintaining that type of refrigerators.
- • The trainer consists of a refrigerator cabinet, a condensing unit, a trolly of refrigeration cycle components and another trolly for tools and equipment necessary for assembling the refrigeration system.
• The refrigerator cabinet has a door to isolate the low temperature resulted by the evaporator coil inside the refrigerator and contains two evaporators, each evaporator has a heater to prevent ice formation at the evaporator fan and two sensors, one of them to sense the evaporator temperature and the other to sense the defrost heater temperature.
- • The refrigerator unit also contains a humidifier to adjust humidification needed to store food in the refrigerator and a thermostat
• The condensing unit consists of a compressor, condenser and a liquid receiver in addition to the main power panel of the trainer that includes main ON/OFF with of the trainer, emergency switch, three selector switches, digital displays to display refrigerator cabinet temperature, evaporator temperatures and evaporator defrost heater temperature and a 24h timer to operate the defrost heaters inside the refrigerator unit round the clock.

- The trainer is also supplied with a refrigerant cylinder with its manifold to teach trainees how to charge and discharge refrigerant to refrigeration circuits.
- The trainer allows trainees to learn the sequence of refrigeration cycles creation and maintenance as they are performed in real life and digital manifold The trainee should first perform mechanical setup of the refrigeration components needed for the required refrigeration cycle.
- Then, trainees should perform the pipe connections and check them, then evacuate moisture in the pipes using the nitrogen cylinder and the digital manifold, then vacuum the system using the vacuum pump and digital manifold.
- Then, trainees have to charge the refrigeration cycle with refrigerant from the refrigerant cylinder using the recovery machine, a wireless scale to identify the amount of refrigerant taken from the refrigerant cylinder to the cycle, a clamp ampere device is used also to check charging the refrigerant and a sight glass to visual passing the refrigerant through pipes and assure there is no bubbles through the refrigerant in the cycle.
- The trainees have to perform the leakage test using the leakage detector and perform the electrical setup of the refrigeration components.
- After performing the experiment, the trainee should learn how to discharge the cycle from the refrigerant.
- The educational unit allows trainees to gain these skills and much more by safe experimentation.
