First, as shown in FIG. 2, the total heat exchanger 1 is installed between the indoor side A and the outdoor side B, and, for example, through the well-known rotor type total heat exchanger 1, the indoor side A The air of the outdoor side B is heated by the above-mentioned heat absorption of the total heat exchanger 1 and supplied to the indoor side A. That is, the dirty air on the indoor side A removes all of the indoor air retained heat in the order of the indoor air intake port 3a, the exhaust air filter f2, the total heat exchanger 1, the exhaust fan 4b, and the indoor air exhaust port 3b. After being captured by the heat exchanger 1, it is discharged outside. On the other hand, as for the outside air, the outside air intake 2b → the air filter f1 on the air supply side → the total heat exchanger 1 → the air supply fan 4
In the order of a → outside air supply port 2 a, the outside air is heated by the total heat exchanger on the way, and then supplied to the indoor side A. The problem during this time is that when indoor air containing bacteria and contaminants comes into contact with the total heat exchanger 1, the bacteria and the like adhere to the total heat exchanger 1 and then are taken in and heated by the outside air. At the stage where the position of the total heat exchanger is moved (rotated), the entire heat exchanger portion to which the bacteria and the like have adhered is brought into contact with the supply air flow, and the attached bacteria and the like are sent back and scattered to the indoor side A. It is.

Next, a description will be given of a health air conditioner shown in FIG. 1 according to an embodiment of the present invention. The healthy air-conditioning apparatus 100 according to the present invention is installed between the indoor side A and the outdoor side B, and converts the air on the indoor side A to the outdoor side via a total heat exchanger (rotor-type total heat exchanger) 1. B is exhausted, and the air on the outdoor side B is supplied to the indoor side A.
