Abstract:
An air conditioner in combination with a vehicle having a windshield and a passenger compartment comprising:a case which forms a plurality of air passages in which air flows; a cooling heat exchanger arranged in said case for cooling the air; a heating heat exchanger arranged in said case at a downstream side relative to said cooling heat exchanger, for heating the air; temperature adjusting means for adjusting a temperature of air blown into the passenger compartment by adjusting a ratio of an amount of warmed air heated by said heating heat exchanger to an amount of cooled air cooled by said cooling heat exchanger and bypassing said heating heat exchanger; a face opening portion provided at a top area of said case for blowing air with a temperature adjusted by said temperature adjusting means toward a passenger head area; a hot air passage provided behind the heating heat exchanger, said hot air passage extending upwardly to the face opening portion; a foot opening portion provided at a bottom area of said case, said foot opening portion having an inlet for introducing warmed air from said hot air passage and an outlet for blowing air with a temperature adjusted by said temperature adjusting means toward a passenger foot area; a face cool air passage provided above said heating heat exchanger for bypassing said heating heat exchanger and for introducing said cooled air from said cooling heat exchanger to said face opening portion; and a foot cool air passage provided at a lateral side of said face cool air passage independently, the foot cool air passage extending downwardly to said inlet of said foot opening portion for bypassing said heating heat exchanger and for introducing said cooled air from said cooling heat exchanger to said inlet of said foot opening portion, and for mixing said cooled air from said foot cool air passage and said warmed air heated by said heating heat exchanger at said inlet of said foot opening portion.
