Vehicle air conditioner

A vehicle air conditioner comprising:

• internal air paths through which an internal air flows into a cabin;
• external air paths arranged in parallel to the internal air paths and through which an external air flows into the cabin;
• a cooling heat exchanger arranged in at least the internal air paths to exchange heat with at least the internal air;
• a blowing means for blowing the internal air of the internal air paths and the external air of the external air paths;
• first air outlets for blowing the internal air after passing through the cooling heat exchanger toward the passenger in the cabin;
• and
• second air outlets for blowing out the external air after passing through the external air paths toward the parts other than the passenger in the cabin;
• wherein the blowing means is arranged downstream of the cooling heat exchanger in the air flow.

• external air paths arranged in parallel to the internal air paths and through which an external air flows into the cabin;
• heat exchangers arranged in at least the internal air paths to exchange heat with at least the internal air;
• a blowing means for blowing the internal air of the internal air paths and the external air of the external air paths;
• first air outlets for blowing the internal air after passing through the heat exchangers toward the passenger in the cabin;
• and
• second air outlets for blowing out the external air after passing through the external air paths toward the parts other than the passenger in the cabin;
• wherein the external air paths make up bypasses for the heat exchangers.

A vehicle air conditioner comprising:

• an internal air blowing means for blowing an internal air;
• an external air blowing means arranged independently of the internal air blowing means for blowing an external air;
• internal air paths in which the internal air blown by the internal air blowing means always flows;
• external air paths in which the external air blown by the external air blowing means always flows;
• heat exchangers arranged in both the internal air paths and the external air paths to exchange heat with the external air and the internal air;
• first air outlets arranged at the downstream end of the internal air paths for blowing the internal air after passing through the heat exchangers toward the passenger in the cabin;
• and
• second air outlets arranged at the downstream end of the external paths to blow the external air after passing through the heat exchangers toward the parts other than the passenger in the cabin.
