Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は、換気手段を備えた車両用空調装置に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to a vehicle air conditioner equipped with ventilation means.
（従来の技術）
一般に、車室前方に配置され車内又は車外から空気を取
入れ車室内に冷風を吹出す冷房装置を備えた自動車等の
車両は知られている。(Prior Art) Vehicles such as automobiles are generally known that are equipped with a cooling device that is disposed at the front of the vehicle interior and takes in air from inside or outside the vehicle and blows cold air into the vehicle interior.
ところで、そのような冷房装置を備えた自動車において
、夏期炎天下に長時間屋外駐車した場合、自動車の車室
内の温度が高くなり、車室内に熱気が滞留しているので
、乗員の搭乗時に乗員が冷房装置を作動させても、車室
内の温度が快適な温度に低下するまでかなりの時間を要
し、多大な不快感を与えると共に、冷房装置の冷房効果
の立ち上がりを悪くする。By the way, if a car equipped with such an air conditioner is parked outdoors in the hot summer sun for a long time, the temperature inside the car's cabin will rise and the hot air will accumulate inside the car, causing the occupants to become Even when the air conditioner is activated, it takes a considerable amount of time for the temperature inside the vehicle to drop to a comfortable temperature, causing a great deal of discomfort and slowing down the cooling effect of the air conditioner.
そこで、それを防止するために、例えば特公昭５９−５
１４５１号公報に記載されるように、駐車時において、
車室内の温度が所定温度以上のときに、車内と車外の空
気を交換する換気用ファンを、”太陽電池によって作動
させる換気装置が提案されている。Therefore, in order to prevent this, for example,
As stated in Publication No. 1451, when parking,
A ventilation system has been proposed that uses a solar battery to operate a ventilation fan that exchanges air between the inside and outside of the car when the temperature inside the car exceeds a predetermined temperature.
（発明が解決しようとする課題）
ところが、そのような換気用ファンは、エンジンが停止
している駐車時においてのみ作動するので、駐車直後に
おいて、車室内の温度が十分に低くなっておらず車室内
の内気温が車室外の外気温よりも高い場合がある。その
ような場合、駐車直後に冷房装置を作動させて車室内の
温度を早期に快適な温度まで低下させようとしても、車
室内には温度の高い空気が充満しているため、車室内の
温度が快適な温度に低下するまでかなりの時間を要する
。(Problem to be Solved by the Invention) However, such ventilation fans operate only when the engine is stopped and the vehicle is parked. The internal temperature inside the vehicle may be higher than the outside temperature outside the vehicle. In such a case, even if you try to quickly reduce the temperature inside the car to a comfortable temperature by starting the air conditioner immediately after parking, the temperature inside the car will still drop because the car is filled with high-temperature air. It takes a considerable amount of time for the temperature to drop to a comfortable level.
特に、冷房装置がオートエアコンである場合においては
、駐車直後は車室内の空気を循環させる内気循環状態に
あるのが通例であり、そのような内気循環状態で、冷房
装置を作動するようにしても、車室内の温度か高いと、
冷房装置の負荷が大きく、冷却効率が低くなり、快適な
空調状態への移行にかなりの時間を要する。In particular, when the air conditioner is an automatic air conditioner, it is normal for the vehicle to be in an air circulation state where the air inside the vehicle is circulated immediately after the vehicle is parked. Also, if the temperature inside the vehicle is high,
The load on the air conditioner is large, the cooling efficiency is low, and it takes a considerable amount of time to reach a comfortable air conditioned state.
本発明はかかる点に鑑みてなされたもので、炎天下駐車
直後等の車室内の温度が高い場合において、快適な空調
状態への移行を迅速に行える車両用空調装置を提供する
ことを目的とする。The present invention has been made in view of the above, and an object of the present invention is to provide a vehicle air conditioner that can quickly shift to a comfortable air conditioning state when the temperature inside the vehicle is high, such as immediately after parking in the hot sun. .
（課題を解決するための手段）
本発明は、内気温と外気温とを比較判定することにより
、冷房装置の負荷の小さい状態で冷房作動させるように
し、快適な空調状態への移行を迅速に行えるようにした
ものである。(Means for Solving the Problems) The present invention enables the air conditioner to operate in a state where the load on the air conditioner is small by comparing and determining the inside temperature and the outside temperature, thereby quickly transitioning to a comfortable air conditioned state. It has been made possible to do so.
そのために、本発明は、車室前方に配置され車内又は車

(step S1), the compressor of the air conditioner 4 (A/C) is turned on (step S2), and then it is determined whether the ventilation switch 35 (ventilation SW) is turned on (step S3).

の通常作動となって（ステップＳ６）、終了する。If the ventilation switch 35 is ON, ventilation is necessary, so the process moves to step S4, and the ventilation switch 35 is OFF.
If F, there is no need for ventilation, so the process moves to step S5, and the air conditioner 4 is turned on without operating the ventilation fan 22.
The normal operation is started (step S6), and the process ends.

である。。In step S4, the signals from the inside temperature sensor 33 and the outside temperature sensor 34 are compared to determine whether the inside temperature is higher than the outside temperature. If it is higher, the process moves to step S7, and the outside temperature is 25 degrees Celsius or higher. If the outside temperature is 25°C or higher, the process moves to step S8, and the Evaporator sensor 12 determines whether the evaporator temperature is 15°C or higher. If,
In step S9, the inside/outside air switching door 5 of the air conditioner 4 is set to the outside air intake position P1 to bring in outside air, and in step S10, the ventilation fan 22 is activated, and the ventilation fan 22 discharges hot air from the vehicle interior as the air conditioner 4 operates. After performing cool-down ventilation, the process returns to step S3. Note that the power source for operating the ventilation fan 22 is an on-vehicle battery. .

In the case of NO, the process moves to step S5, where no ventilation is performed, and when the ventilation fan 22 is operating, the ventilation fan 22 is stopped, and the inside and outside air is turned off to increase the cooling efficiency in the normal operation of step S6. The switching door 5 is at the inside air intake position P2, and the inside air is in a circulating state.

内気温がそれほど高くないと考えられるからである。These steps sa, S7. The reason why ventilation is not performed in SS is that if the outside temperature is higher than the inside temperature, the temperature will rise due to the introduction of outside air, and if the outside temperature is 2.
This is because when the evaporator temperature is less than 5°C, it is considered that the inside temperature is not so high, and when the evaporator temperature is less than 15°C, it is considered that the inside temperature is not so high.
上記実施例では、クールダウン換気における換気ファン

が、これらの温度判定は省略するようにしてもよい。In the above embodiment, in order to operate the ventilation fan 22 during cool-down ventilation, in addition to comparing and determining the inside temperature and outside temperature, temperature determinations of the outside air temperature and the evaporator temperature are also performed, but these temperature determinations are omitted. You can do it like this.
上記実施例では、換気ファン２２を荷室２３内に配設し
ているが、リヤピラー内に配設するようにしてもよい。In the above embodiment, the ventilation fan 22 is disposed within the luggage compartment 23, but it may also be disposed within the rear pillar.
