Installation, commissioning and maintenance of condensers
The basic functioning of a condenser.
Installing a condenser properly, including control and safety equipment.
Adjusting the safety and control switches. Checking the hot-gas and liquid lines
in correct positions. Start up and shut down a condenser and check the good
working conditions, including by making measurements during operation.
Checking the surface of the condenser. Methods for condenser surface cleaning
and fins adjustments.
Installation, commissioning and maintenance of evaporators
The basic functioning of an evaporator (including defrosting system).
Installation of an evaporator including control and safety equipment.
Adjusting the safety and control switches.
Checking the liquid and suction pipelines in the correct position and checking
the hot gas defrost pipeline. Start up and shut down an evaporator and check
the good working of the evaporator, including by making measurements during
operation. Functional checking of the reverse cycling control device.
Checking the surface of the evaporator. Methods for evaporator surface clean-
ing and fins adjustments.
Piping
Professional brazing is another key component for safe and state-of-the-art HC
system installation and servicing. Brazing leak-free joints on metallic tubes and
pipes that can be used in refrigeration, air-conditioning or heat pump systems.
Make/check pipe and component supports and vibration elimination. Knowledge
about the designing and dimensioning of the different refrigeration system sec-
tion pipes including risers. The behaviour of lubricants within the refrigeration
system and the influences of the dimensioning of pipe work in relation to lubri-
cants. Develop strategies to minimise mechanical connections like flaring or
flanges and to provide a sealed (hermetic) system.
