An air inlet passage (1) and an air outlet passage (2) are arranged for ventilation in an upper part of a wall (102). An exchange of heat is performed with respect to fresh air (36) to be supplied from the outside to the inside of a room (101) through the inlet passage (1). A heat exchanger (3) is arranged to perform the exchange of heat. The heat exchanger (3) is constructed of a thermoelectric module (4) having the Peltier effect, a first heat-absorbing-side heat transfer unit (5) arranged adjacent to a heat-absorbing side of the module (4), a second heat-absorbing-side heat transfer unit (6) of the radiator type arranged in the inlet passage (1), a heat-absorbing-side circulating passage (7), a heat-absorbing-side pump (8), a first heat-dissipating-side heat transfer unit (9) arranged adjacent to a heat-dissipating side of the module (4), a second heat-dissipating-side heat transfer unit (10) of the radiator type, a heat-dissipating-side circulating passage (11), a heat-dissipating-side pump (12), a heat-dissipating-side fan (13), a heat transfer medium (14) (see FIG. 2) filled in the circulating passages (7,11), and a power supply (15). <IMAGE> |
