THERMOELECTRICS
COOLING AND HEATING
The thermoelectric principle was discovered by J. C. A. Peltier. The temperature generating parts of thermoelectric
systems are therefore referred to as Peltier elements. Thermoelectrics are based on the fact that cold or heat energy is
generated when a DC current is conducted between different types of metal. The heating or cooling capacity is further
enhanced by heat exchangers and air fans. Ideal for low and medium cooling volumes.
ABSORPTION TECHNOLOGY
THE SOUND OF SILENCE
A concentrated ammonia solution is heated in a boiler and expelled as vapour. The pressurised ammonia gas is then
liquefied in a condenser. Supplied with hydrogen, it evaporates and extracts heat from the storage container. The
ammonia gas then enters the absorber where it is reabsorbed in a weak solution of ammonia. Finally, the saturated
solution flows back to the boiler where the whole cycle starts again.
COMPRESSOR TECHNOLOGY
STANDARD COOLING AND FREEZING
Compressor units operate using a refrigerant that changes from liquid to gaseous state in the evaporator. The evaporation
extracts heat from the interior of the cooling unit – the temperature drops. The compressor draws in the refrigerant,
compresses it and passes it on to the condenser. Here, the absorbed heat is released to the atmosphere. The refrigerant
liquefies again and flows to the evaporator, where the cycle begins again.
THREE COOLING SYSTEMS
FOR MOBILE USE
A quick note: no cooling system exists that can handle every conceivable task. Whether you’re better off with a
thermoelectric, a compressor or an absorption cooling unit depends entirely on how and where you intend to use mobile
cooling. Start off with a detailed comparison of the individual systems and their features. This will then automatically
point you to “your” cooling technology and to “your” cooling unit.
