説明

Having had imagined the heat recovery from exhaust air out of a compost bed, experiments for rising the temperature of water (medium fluid) by a packed column heating tower of counter flow-type were conducted. There was a considerably larger temperature rise of water (30°C of the maximun), and a higher value of the heat recovery efficiency (72% in average), as compared with those for the buried-tube-type heat extractor. Therefore, the proposed heat recovery system seemed likely to be valid.<br>An overall volumetric coefficient of enthalpy transfer of the tower Ka depended only on the mass velocity of dry air G, and it was arranged by the experimental equation Ka=27G0.76 within the error of±20%.<br>Assuming the linearity between the enthalpy and temperature of saturated air, approximate solutions of the temperature of water and the enthalpy of moist air in the tower were derived.<br>It was illustrated that the volume of compost bed and the mass velocity of water in the tower which would be required to get the desired water temperature at the outlet of the tower could be graphically determined by the approximate solutions.
