Oil Return in Refrigeration Systems- Engineering Lab Training Systems.
Technical Description
The unit addresses the
problem of oil return in refrigerant circuits. In refrigerant circuits
the lubricant is carried through the pipe system by the refrigerant. Oil
may impact the compressor if the system is overfilled. If the system is
underfilled the compressor may run dry. The selection of the correct
diameter and arrangement of pipework is therefore of key importance. The
effect of the refrigerant flow rate on the oil return to the compressor
is demonstrated on this unit with the aid of glass intake pipes. A
complete refrigerant circuit is mounted on the rear of the demonstration
panel. To demonstrate the effect of different pipe diameters and
routing, individual sections can be selected using ball valves.
Pressures and flow rates are measured in the refrigerant circuit. The
laboratory trolley mounted system is flexible and suitable for use in
different seminar or training rooms.
