Recycling of the unit
Introduction
The air conditioner, heat exchanger or free cooling unit is designed to last for a number
of years. When the time comes for the unit to be recycled, the following precautions
should be taken to protect our environment.
Please note that the guidelines are general – local rules and procedures may overrule
these guidelines and should be observed and followed carefully.
Some of the below mentioned components may not be of relevance to your product.
Main components
The main components of the unit are the:
•
Mechanical cooling system including refrigerant (only in air conditioners)
•
Printed circuit boards (PCB’s) with electronic components and connecting wires
•
Fan(s)
•
Metal parts such as cover and air duct plates
•
Recuperator (only in heat exchangers)
•
Filter materials – to be recycled according to local regulations
Mechanical
cooling
The mechanical cooling includes pipes, compressor, valves, pressure switches etc. It is
very important that all refrigerant is evacuated from the system when the unit is
recycled. The various parts of the mechanical cooling shall then afterwards be
separated and sorted according to local regulations.
Printed circuit
board (PCB)
It is common that a set of local rules is made for the recycling of printed circuit boards
as well as connecting wires. Generally it is important to separate the metal parts from
the wires and PCB’s before recycling.
Fans
The fan(s) consist of plastic, metal and often also an internal PCB. They are subject to
recycling and should be recycled according to local regulations.
Metal parts/wires
The metal parts are uncritical to recycle and can be left to local ”scrap dealer”. A few
parts might have a thin visible layer of PVC-foam insulation. The PVC must be
separated from the metal and recycled separately.
Recuperator
The recuperator is manufactured of epoxy coated alu metal sheets, and it can be left to
local ”scrap dealer”.
