Outdoor Thermoelectric Cooler
THERMOELECTRIC COOLING UNITS FOR
OUTDOOR ENCLOSURES AND KIOSKS
The AA-480 Outdoor Thermoelectric Cooler is an is an Air-to-Air thermoelectric assembly (TEA) that
uses impingement flow to transfer heat. It offers dependable, compact performance by cooling
objects via convection. The AA-480 has whopping 480 Watts of cooling power and a COP = 1 at
ΔT=0°C. Heat is absorbed and dissipated thru custom designed heat exchangers with high aspect
ratio, air ducted shrouds and high performance fans. The heat pumping action occurs from custom
designed thermoelectric modules that achieve a high coefficient of performance (COP) to minimize
power consumption.
This product series has been designed to pass rigorous Telcordia test requirements for outdoor
environments. This is due to the selection of world class components such as brand name fans with
the highest degree of environmental protection and lifetime guaranteed waterproof connectors,
heavy duty anodization on the high-density heat exchangers, overheat protection, and double
environmental seals for the thermoelectric modules.

Installation and Service manual
Installation:
1. The TE assembly must be mounted in a cabinet with “Hot side”
mounted externally.
2. Suitable cabinet cutout is
310x284
mm.
3. Recommended for general purposes: the TE assembly should be fastened
according to picture below so that the gasket material will seal off around
the flange of the assembly.
4.
TheTEassembly is recommended to be positioned with "Cold side" in
vertical direction with wires facing downwards (heat sink fins in vertical
direction).
5. Note that condensation may occure. Standing water on the heat sink
should be avoidedand drip tray may be required.
6. The TE assembly must be protected from external force or violence.
7. The power line to the assembly needs to be protected by a fuse. The fuse rating
should be of at least the nominal current of the assembly. It must withstand
150% of rated current for at least 60 seconds.
This is valid at Ta=35°C. Fuse ratings for otheram bient temperatures (x°C) can
be calculated with the formula I[x°C]=I[35°C]/(1+0. 005*(x-35)).
This is valid when regulating with an ON/OFF regulation. At rapid temperature
cycling where this is applicable, there can be need for even higher fuse ratings.
8. Max ripple on supplied power =5%.
9. Switching power to TEM:s at frequencies between 0.01 Hz to 5 kHz will render
premature failure of modules and must be avoided.
Service:
Fan impellers and heat sinks must be cleaned on regular intervals to reduce
risk for overheating and reduction of cooling function. The interval may vary
depending on environment.
