- step S460 the A / C controller 20 counts up the timer Tcomp ⁇ on for counting the accumulated operation time of the compressor 9, and proceeds to step S470. Since the timer Tcomp ⁇ on is reset to 0 only immediately after the ignition is turned on in step S260, in step S460, the A / C controller 20 starts counting up from the value before the start of pre-air conditioning (before the ignition is turned off). Thereby, the A / C controller 20 can integrate the time during which the indoor heat exchanger 6 is operated as the heat absorber during the normal operation and the subsequent pre-air conditioning.

- the intake door when there is a heating request in the passenger compartment during pre-air conditioning, the intake door is controlled to enter the inside air circulation mode for the first predetermined time and the outside air introduction mode for the second predetermined time.
- the switching was performed alternately. For this reason, even if an occupant gets into the vehicle before the preset scheduled departure time, there is no window fogging and the vehicle can be started immediately.
- the initial value of the first predetermined time is set to be longer than the initial value of the second predetermined time. For this reason, basic operation can be made into inside air circulation mode, and there is an effect that ventilation heat loss can be reduced and power consumption can be suppressed.
- the pre-air-conditioning control means determines the operation start time of the heating means based on the vehicle interior temperature or the outside air temperature and the scheduled departure time. For this reason, there is an effect that it is possible to provide pre-air conditioning without window fogging without providing a humidity sensor or a judgment control logic using a humidity detection value.
- the operation in the outside air introduction mode is performed only when the cooling means is operated before the ignition is turned off or during the pre-air conditioning. For this reason, the window fogging by the condensed water on the surface of the indoor heat exchanger is prevented, and when there is no condensed water, there is an effect that the heat loss of ventilation can be reduced and the power consumption can be suppressed.
- the first predetermined time and the second predetermined time are corrected according to the cumulative operation time of the cooling means before ignition off and during pre-air conditioning. For this reason, the operation time in the inside air circulation mode and the operation time in the outside air introduction mode can be corrected according to the amount of liquid water adhering to the indoor heat exchanger, reducing ventilation heat loss and reducing power consumption. There is an effect that it can be suppressed.
- the first predetermined time and the second predetermined time are corrected according to the amount of solar radiation detected by the solar radiation sensor. For this reason, under conditions where the amount of solar radiation is large and window fogging is unlikely to occur, it is possible to correct the operating time in the inside air circulation mode and shorten the operating time in the outside air introduction mode, further reducing ventilation heat loss, There is an effect that can be suppressed.
- the first predetermined time and the second predetermined time are corrected according to the outside air temperature detected by the outside air temperature sensor. For this reason, under conditions where the outside air temperature is low and window fogging is likely to occur, the operating time in the inside air circulation mode is shortened and the operating time in the outside air introduction mode is corrected to be longer, so that window fogging can be reliably prevented and ventilation heat loss There is an effect that power consumption can be reduced.
- the vehicle air-conditioning apparatus and the vehicle air-conditioning method of the present invention are not limited to this embodiment, and can be appropriately changed without departing from the gist of the present invention.

Abstract
Description
図1は、本発明に係る車両用空調装置の構成例を説明するシステム構成図である。図1において、車両用空調装置は、車室内に温度調整された空気を吹き出す冷暖房空調(HVAC:Heating Ventilation and Air-conditioning)ユニット4を備えている。また車両用空調装置は、冷却手段として、室内熱交換器6、膨張弁7、コンデンサ8及びコンプレッサ9を備えた冷却システムと、加熱手段として、ヒータコア10,電動ウォータポンプ11及びPTCヒータ12を備えたヒータシステムと、を備える。
室内熱交換器6は、膨張弁7、コンデンサ8、コンプレッサ9とともに、冷却手段である冷却システムを構成している。冷却システムは、加圧液化された冷媒が膨張弁7から霧状に室内熱交換器6へ放出される際に気化熱を奪うことで、室内熱交換器6に流通する空気と熱交換を行い、空気の冷却を行う。室内熱交換器6において熱交換が終了した冷媒は、電動冷媒圧縮機であるコンプレッサ9により圧縮される。コンプレッサ9は、図示しない電動モータによって駆動され、供給される電力に応じた圧縮能力を備えている。
室内熱交換器6を通過した空気は、空気通路の下流に設置されたヒータコア10に供給されて、空気の加熱が行われる。ヒータシステムは、ヒータコア10と、PTCヒータ12と、ポンプ11を有する。ヒータコア10には温水が流通する。ヒータコア10は、導入された空気と温水との間で熱交換を行って、空気の加熱を行う。ポンプ11は電動モータ11aにより駆動され、ヒータコア10とPTCヒータ12との間の温水の循環を行う。
ヒータコア10の直前に設けられたエアミックスドア13は、室内熱交換器6を通過した空気の内、ヒータコア10を通過する空気の比率を制御する機能を有する。A/Cコントローラ20は、エアミックスドア13の開度を制御することにより、吹出口14から車室内へ吹き出す空気の温度が目標温度となるように調整する。図1には、1つの吹出口14のみを示しているが、実際には、車室内には複数の吹出口(ベンチレータ)及びデフロスタ(DEF)が設けられており、運転者が選択する、もしくはオートエアコン制御によって要求される吹き出しモードに応じて、空調された空気が吹き出す吹出口の数が適宜制御される。
次に、図2~5の制御フローチャートを参照して、本発明の車両用空調装置の制御部であるA/Cコントローラ20による制御内容を説明する。尚、特に限定されないが、本実施形態では、A/Cコントローラ20は、CPUと、作業用RAMと、不揮発性メモリであるEEPROMと、入出力インタフェースとを備えたマイクロプロセッサで構成されている。そして、CPUがEEPROMに記憶された制御プログラムを実行することにより、A/Cコントローラ20の制御機能が実現されている。
図5は、ステップS380やステップS390のΔt1(第1所定時間)やΔt2(第2所定時間)の補正のフローを示している。
