PURPOSE:To make improvements in comfortableness ever so better, by making heating capacity in a heating apparatus controllable, while constituting the downstream of the heating apparatus as being bisected into a ventilation flue with an air flow regulating door mixing cold air with hot air and feeding an upper blowoff port with this mixed air and another ventilation flue feeding a lower blowoff port with the hot air directly. CONSTITUTION:In case of a by-level mode, an air-mix damper 7, a deflector door 15, a vent deflector damper 9 and a floor door 17 are all seat to a full-line position each and a blower motor 2 is driven, taking in the outside air. This fresh air is dehimified and cooled, then a part of it is bisected into the foot blowoff port side and the vent deflector side at the deflector door 15 after passing through a heater core 4. On the other hand, cold air bypassing the heater core 4 at the air-mix damper 7 is mixed with hole air branched off at the deflector door 15 and blown to a deflector blowoff port. When the vent deflector damper 9 is selected, it comes to a vent blowoff. With this constitution, unevenness in blowoff temperature at the upper and lower sides is eliminated, thus comfortableness is improvable even so better. |
