In this study, the innovative air conditioning duct design is in the form of a U-type air duct in the horizontal position, and
experimental studies have been carried out at different air velocities and different atmospheric conditions. The designed air
conditioning duct has innovative characteristics due to its possibility to be applied in environmentally friendly, high humidity
environments. Hot and cold heat sources were created with the help of thermoelectric elements (peltiers) placed between two Ushaped
channels. In order to cool and dehumidify the air passing through the duct, cold stored masses with conical geometry shape
were used. The dehumidified air passes over the heat transfer elements placed in the heating channel, increasing the sensible heat of
the air and bringing the temperature to the desired level. The formation of hot and cold heat sources is due to the DC electrical energy
applied to the thermoelectric elements. In the study, air conditioning was carried out in the duct according to the cooling load and
heating load provided by the thermoelectric elements. The theoretical condensation amount was calculated by measuring the
psychometric values of the atmospheric air controlled by humidity and air temperature. When this value and the amount of
condensate obtained from the experiments were compared, it was found that the condensate generation efficiency of the cooler
masses was 33% on average. The heating coefficient performance (COPIP) of the thermoelectric element in the heating channel was
found to be 0,917. The cooling performance of coefficient (COPSM) in the cooling channel of the thermoelectric module was
calculated as 0,809. The specific moisture removal rate for unit energy was found to be 0,66 kg-H20/kWh and specific energy use
was 1,512 kWh/kgH20.
