All equipment is delivered with air-in on service/operator side and air discharge on customer side. The air flow is
throught the counter, from service side to the discharge opening on customer side.
If there is no possibility to discharge the hot air on customer side, provide an opening either on left/right side or on
the service side to place an air grill.
Whichever option is chosen, please take care that only cold air from the room gets drawn into the condenser unit
and no warm recycled air is drawn back into the condenser!.
For option 1 (free flow in one line) we recommend to make a tunnel (wood or metal) to lead the hot air out of the
condenser unit. If the solution with air discharge on customer side is not possible, you can choose option 2 (rear
ventilation) with air inlet and hot air discharge on same side. An additional fan can help to expel hot air out of the
counter.
Distance between inlet and discharge openings (Variation 2) should be as wide as possible to avoid
re-circulation of hot discharge air!
Please take care that the inlet / outlet openings for the air-in and air-discharge are wide enough and are NEVER blocked!
No brake or obstruction of the air flow at any time. The condenser of a cooling system works as a heat exchanger
and has to transfer the thermal energy of food/drinks and the electrical power consumption of the compressor to
the ambient air.
Protection of the condenser:
Air grills or a stainless steel filters protects the coil against dust, fatty air and damage.
It further prevents injury as the condenser fins are very sharp!
2.7. Air ventilation
Variantion 1:
Air flow directly through the condensing unit (and
thecounter) in straight line forward..
Variantion 2:
Air inlet and hot air discharge on the same side
(rear ventilation)
Air grills with small perforation or louvers with narrow blades can increase air resistance. So please
use appropriate air grills. Minimum size of air grills: twice of surface area of the condenser!
Ventilation openings (air-in and discharge) are never blocked!
Refrigeration capacity will be reduced dramatically and the compressor could be destroyed.
