Part
Correct ventilation of the condensing unit of self contained display cases is very important for the correct and efficient
functioning of the display case. The condenser has to transfer the heat of the refrigerant (energy of the products)
and the electrical heat of the compressor to the surrounding air in the room in order for the cooling process to
work.
All self-contained units come with a moveable s/s compressor housing. This offers the possibility to locate the
condenser face near the air grill (air-in) of the counter to avoid cirulation.
2.6. Prevention of the most common error
A) Compressor
The compressor pumps the refrigerant through the cooling system.
B) Fan
The condenser fan draws fresh air in from the room and passes it through
the compressor expels the hot air out of the condenser.
C) Condenser
The condenser coil is referred to as heat exchanger and cools the returning
hot refrigerant.
Don‘t allow warm air retourning to the room to re-circulate and remix with cooler air coming in from
the room.
