Description
The replacement of a faulty compressor or other components
of the refrigeration system are amongst the repeated activities of a
mechatronics engineer for refrigeration. It allows for training in these
processes. The consequences of incorrect procedures can be demonstrated. The
components are integrated into an operational refrigeration system. This allows
for the practical testing of the functionality of individual components after
replacement. The following activities must be carried out e.g. after replacing
a compressor:
Refrigerant displacement (pump-down) into the
condenser/receiver (this not be possible, siphoning off the refrigerant)
Disconnection of the compressor at the service valves
Disconnection of electrical connections
Compressor replacement, correcting oil level, if necessary
Reconnecting electrical connections
Reconnecting the compressor with the service valves
Evacuating the compressor and making the connection to the
system
Compressor test run, checking for leaks and replenish
refrigerant, if necessary
Checking the system pressures
Learning Objectives/Experiments
Familiarisation with and carry out basic activities for the
servicing of refrigeration systems
Replacement of
Compressor
Pressure switch
Filter/drier
Solenoid valve
Expansion valve
Refrigerant displacement (pump-down)
Mechanical and electrical assembly and disassembly of
components
Replenish refrigerant and compressor oil
Leak test
Compressor test run
Adjustment of expansion valve and pressure switch
Specification
