Description

The SUP120 bench allows the data acquisition and the refrigeration cycle plot on enthalpy diagram for any machine running on R134a or R448a.

Students will initially connect the pressure measuring hoses (standard manifold) then set up the temperature probes (clamps equipped with thermocouple) to the characteristic points of the circuit (suction and discharge compressor, expansion valve inlet).

They will then connect electrically all the sensors on the acquisition device (quick connectors) and connect it to a PC via WIFI. They then launch software appropriate for fluid used.

The unit is delivered with all the necessary material to connect the sensors on the box (hoses, manifold)

The manufactory of this equipment is conforming to European standards.

The supervision bench SUP 120 includes the following elements:
1. 3 pliers of temperature measurement with type K thermocouple
2. 3 extension cords of 1.5m of thermocouple wire with quick connectors
3. A refrigeration manifold with three hoses (blue, red and yellow) equipped with valves
4. Two pressure sensors with analog output and quick connector
5. An acquisition device equipped with three thermocouple inputs, two analog inputs.
6. An acquisition software allowing to:
- Visualize the measured values of a block diagram (pressures and temperatures)
- Draw the evolution curves in function of time (pressures and temperatures)
- Draw the refrigerating cycle in enthalpy diagram in real time and display the values of enthalpy
- Save the data to an Excel file type
