<p>PURPOSE:To make measurement of temperature and humidity accurate and to ensure a control of operation by disposing a humidity sensor below a temperature sensor and by disposing a holder of these two sensors above a secondary filter. CONSTITUTION:A temperature sensor 33 and a humidity sensor 35 are disposed respectively on the side facing an air inlet 11a in a heat exchanger 5 disposed in an air passage. The temperature sensor 33 and the humidity sensor 35 are held integrally by a holder 39 and these can be installed at a time. In the holder 39, the temperature sensor 33 is disposed above the humidity sensor 35 and the holder 39 is disposed above a secondary filter 37 provided at the air inlet 11a of a grille 11. Accordingly, not only the temperature sensor 33, but also the humidity sensor 35 hardly comes into contact with the secondary filter 37 and a frame thereof, and even when the humidity sensor 35 comes into contact with the filter 37 and the frame, it is hardly impaired, since the outer part of the humidity sensor is formed of soft resin.</p> |
