Abstract
Description
本発明は、電動車両に具備される空調装置に関する。 The present invention relates to an air conditioner provided in an electric vehicle.
ハイブリッド自動車および電気自動車等の電動車両は近年、その低燃費性および環境性能を評価され、市場の一角を占める傾向にあり、技術的にも開発が盛んである。
特に、当該自動車類に具備される空調装置は電力消費が大きく、技術上の要点のひとつである。In recent years, electric vehicles such as hybrid vehicles and electric vehicles have been evaluated for their low fuel consumption and environmental performance, tend to occupy a part of the market, and are technically developed.
In particular, the air conditioner provided in the automobiles consumes a large amount of power and is one of the technical points.
従来の技術によれば、電動車両に具備される空調装置は、暖房は抵抗発熱、冷房は従来式カーエアコンの併用により構成され、駆動には大きな電力が必要である。
蓄電池容量に限定された電気エネルギーのみで走行する電動車両において、当該装置は一充電走行距離等、性能面を脅かす要素となっているが、快適性確保のために必須の装置でもある。According to the prior art, an air conditioner provided in an electric vehicle is configured by heating using resistance heat generation and cooling by using a conventional car air conditioner, and requires a large amount of electric power for driving.
In an electric vehicle that travels only with electric energy limited to the storage battery capacity, the device is an element that threatens performance, such as a one-charge travel distance, but is also an essential device for ensuring comfort.
以上の課題を解決するため、本発明では制動時に運動エネルギーの一部を電力として再利用することを可能としている回生制動装置の出力する電力を、［請求項１］の如く、空調装置で消費し、なおかつ、当該回生制動装置の動作を安定せしめるべく、［請求項２］の如く、所定の熱容量を有する冷媒等に一時的に蓄熱し、所定の時間差をもって供用することを可能とする空調方法を採用する。 In order to solve the above problems, in the present invention, the electric power output from the regenerative braking device that can reuse part of the kinetic energy as electric power during braking is consumed by the air conditioner as in [Claim 1]. In addition, as described in [Claim 2], in order to stabilize the operation of the regenerative braking device, it is possible to temporarily store heat in a refrigerant or the like having a predetermined heat capacity and to use it with a predetermined time difference. Is adopted.
本発明によれば、電力消費の大きな空調装置を、回生制動装置の発生する電力で駆動することで、通常空気中に熱として放散せざるを得ない制動時の運動エネルギーを再利用することとなり、電気エネルギーの節約が可能になる。
また本発明により、所定の熱容量を有する冷媒等に一時的に蓄熱することとすれば、空調装置の消費電力は、室温調整の強弱とは直接無関係となり、常に安定となり、当該回生制動装置の動作も安定する。
同時に、冷媒等に蓄熱された熱量は所定の時間差をもって供用可能であるため、制動時以外でも室温調整が可能である。According to the present invention, by driving an air conditioner that consumes a large amount of power with the electric power generated by the regenerative braking device, the kinetic energy at the time of braking that must be dissipated as heat in normal air is reused. , Saving electrical energy.
Further, according to the present invention, if heat is temporarily stored in a refrigerant or the like having a predetermined heat capacity, the power consumption of the air conditioner is not directly related to the strength of the room temperature adjustment and is always stable, and the operation of the regenerative braking device Is also stable.
At the same time, the amount of heat stored in the refrigerant or the like can be used with a predetermined time difference, so that the room temperature can be adjusted even during braking.

このとき（１４）空調装置（本体）の消費電力は常に安定であることが求められるので、（１７）空調装置（室内機）は直接（１４）空調装置（本体）に接続されない。
（１３）冷媒タンク／ポンプは断熱に優れた密閉容器で、（１５）冷媒流路−１を介して（１４）空調装置（本体）と接続され、（１６）冷媒流路−２を介して（１７）空調装置（室内機）と接続されるが、（１５）冷媒流路−１を流れる冷媒と（１６）冷媒流路−２を流れる冷媒は必ずしも同一ではない。

（１５）冷媒流路−１を流れる冷媒を冷媒▲１▼、（１６）冷媒流路−２を流れる冷媒を冷媒▲２▼とすると、冷媒▲１▼はより流入し（１９）熱交換機を通過しつつ冷媒▲２▼に熱を移動して（２０）冷媒▲１▼流路（出路）より（１４）空調装置（本体）へ復帰される。
このとき冷媒▲２▼は（２４）冷媒▲２▼ポンプの動作により（１８）冷媒▲２▼吸出口から（２５）冷媒▲２▼流路（出路）を介して（１７）空調装置（室内機）で熱交換による空調機能を果たし、（２３）冷媒▲２▼流路（入路）を介して（２２）冷媒吐出口より復帰する。
この構造により（１３）冷媒タンク／ポンプ内の冷媒▲２▼は熱的質量として機能し、制動に伴う巨大な回生エネルギーを熱として充分に吸収・蓄積し、徐々に空調に供することが可能になる。
なお、冷媒▲１▼と冷媒▲２▼が同一である場合は、（１３）冷媒タンク／ポンプを単純な断熱密閉容器に（２４）冷媒▲２▼ポンプのみを具備する構造とすることも可能である。The air conditioner according to the present invention is a part of a drive control device for an electric vehicle as shown in FIG.
