The air conditioning system with organic sorbent is able to utilize the low temperature waste heat. This paper has dealt with dynamic sorption of powder organic sorbent in a fluidized bed during batch cycle operation. The experiments were carried out under the various conditions such as cycle time, inlet air flow velocity, temperature of the heat exchanger, amount of sorbent.
As a result, the cycle time which maximizes the amount of dehumidification became clear. The most suitable cycle time was decided by the balance of the speed of sorption reaction and the effects of heating and cooling. The heating effect and the cooling effect were controlled by the temperature of the heat exchanger. With a rise of the desorption temperature, the most suitable cycle time became short and the amount of dehumidification increased but heat efficiency dropped. On the other hand, with a rise of the sorption temperature, the amount of dehumidification decreased but this system showed an enough dehumidification performance when the sorption temperature is 30°C.
