PROBLEM TO BE SOLVED: To perform the control of a rotary type heat-exchanger in a manner to save energy in a heat-exchanging-ventilating unit for which a rotary type heat- exchanging element is used. SOLUTION: This rotary type heat-exchanging-ventilating unit wherein a ventilation is performed by heat-exchanging the outside air and indoor air, performs the heat- exchange by rotating a heat-exchanging element only when an energy consumed by an air conditioner or the like to generate a quantity of heating which can be recovered by the heat-exchange exceeds an energy required to rotate a heat-exchanging element. A processing air volume of the heat-exchanging element, sensible and latent heat- exchanging efficiencies in the processing air volume, a formula to operate a sensible heat volume and a latent heat volume of air, the energy consumption efficiency of the air conditioner, an energy required to rotatively drive the heat-exchanging element, and control procedures for the heat-exchanging element are stored in a memory section. Then, the controls of all the heat-exchangers are performed by reading the control procedures from the memory section by a central operation device, and by a signal which is output from the central operation device, contact points are made/to open or close to rotate or stop all the heat-exchanging elements. |
