AIR CONDITIONING DEVICE FOR VEHICLE

PROBLEM TO BE SOLVED: To provide an air conditioning device for a vehicle capable of maintaining cooling feeling which is common sensation and saving power.SOLUTION: An air conditioning device for a vehicle comprises a refrigeration cycle having a compressor and an evaporator, and change of an on-state and off-state of the compressor is performed depending on temperature of the evaporator. The air conditioning device for a vehicle comprises: outside air temperature detection means; solar radiation amount detection means; stop determination means for determining change of an on-state and off-state of the compressor after start-up of the compressor 1; and a counter for counting a determination number of the on-state and off-state determined by the stop determination means. When the compressor 1 becomes the off-state after start-up, and detection temperature of the outside air temperature detection means is equal to or more than first regulation temperature and equal to or less than second regulation temperature, and the detected solar radiation amount of the solar radiation amount detection is equal to or less than a regulation amount, when a count value of the counter reaches a predetermined regulation count number determined by the outside air temperature, temperature of the evaporator for turning the compressor to the on-state is made higher than temperature of the evaporator in count. 【課題】体感としての冷房感を保持しつつ省動力化できる車両用空気調和装置を提供する。【解決手段】コンプレッサとエバポレータを有する冷凍サイクルを備え、コンプレッサのオン・オフをエバポレータの温度によって行う車両用空気調和装置であって、外気温度検出手段と、日射量検出手段と、コンプレッサ１の起動後にあって、コンプレッサのオン・オフ変化を判定する停止判定手段と、停止判定手段によるオン・オフ判定回数をカウントするカウンタとを備え、コンプレッサ１が起動後にオフ状態に移行し、且つ、外気温度検出手段の検出温度が第１規定温度以上、第２規定温度以下であり、且つ、日射量検出手段の検出日射量が規定量以下である場合に、カウンタのカウント値が外気温度の値で決められた規定カウント数に達すると、コンプレッサをオンさせるエバポレータの温度を、カウント中のエバポレータの温度温度よりも高い温度に変更する。【選択図】図３
