Abstract
Periodic heat transfer with adsorption and desorption process in an element of the matrix of the rotary total heat exchanger is studied numerically and experimentally. The outlet temperature and humidity variations of the exhaust air and the intake air are predicted respectivily for summer time conditions. Mean values of these results are agree well with the measured ones. Effectiveness of temperature, humidity and enthalpy are also obtained for different flow rates and it is shown that the effectiveness of humidity and enthalpy increase with decreasing the flow rate, but that of temperature does not increase and rather decreases at the relative low flow rates.
