Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an air conditioner for vehicles which can lower a humid exhaust air temperature while maintaining the regeneration efficiency of a desiccant material when quickly heating the desiccant material during the drive of the vehicle and regenerating it in a short time.SOLUTION: A heater core and a PTC heater for heating air, and a dehumidification unit 20 for dehumidifying air are arranged at a second downstream passage and an upstream passage 11c respectively, both passages for passing air in a vehicle interior space. The dehumidification unit 20 includes a desiccant material 21, and a Peltier element 22 which absorbs heat at one face and generates heat at the other face by being energized. Three desiccant materials 21b, 21a and 21c and two Peltier elements 22 and 22 are alternately arranged in a direction orthogonal to an air flow. In the regeneration of the desiccant material 21, the Peltier element 22 is energized.
【課題】車両の運転中にデシカント材を急加熱して短時間で再生する際に、デシカント材の再生効率を維持したまま、排湿空気の温度を低下させることが可能な車両用空調装置を提供する。【解決手段】車室内空間の空気が通過する第2下流通路と上流通路11cとに、それぞれ、空気を加熱するヒータコア及びPTCヒータと、空気を除湿する除湿ユニット20とを設ける。除湿ユニット20は、デシカント材21と、通電されることにより一方の面で吸熱し他方の面で発熱するペルチェ素子22とを含む。3つのデシカント材21b,21a,21bと2つのペルチェ素子22,22とが空気の流れ方向と直交する方向に交互に配置される。デシカント材21の再生時は、ペルチェ素子22に通電する。【選択図】図3 |
