Automotive air conditioner

An air conditioner for an automotive vehicle, comprising:

• a blower for blowing air;
• a cooling heat exchanger disposed between a dashboard within a passenger compartment and an engine compartment, the compartments being divided by a partition, said cooling heat exchanger receiving from its bottom side air which is moved by the blower in an upward direction through the cooling heat exchanger, the cooling heat exchanger being disposed so as to be gradually inclined relative to horizontal;
• and
• a heating heat exchanger disposed substantially horizontally above the cooling heat exchanger for heating the upwardly moving air passing through the cooling heat exchanger,
• wherein the cooling and heating heat exchangers include respective pipes through which refrigerant is introduced and discharged, the pipes having ends which extend through the partition into the engine compartment when the air conditioner is mounted to said vehicle.

An air conditioner for an automotive vehicle, comprising:

• a blower for blowing air;
• a cooling heat exchanger receiving from its bottom side air which is moved by the blower in an upward direction through the cooling heat exchanger, the cooling heat exchanger being disposed so as to be gradually inclined downwardly relative to horizontal;
• a heating heat exchanger disposed substantially horizontally above the cooling heat exchanger for heating the upwardly moving air passing through the cooling heat exchanger;
• and
• a unit case for containing said cooling heat exchanger and said heating heat exchanger, said unit case including a plurality of vertically separable cases, said heat exchangers being vertically sandwiched between said plurality of cases.

• a heating heat exchanger disposed substantially horizontally above the cooling heat exchanger for heating the upwardly moving air passing through the cooling heat exchanger;
• an internal air/external air selector housing disposed above said blower for selectively introducing internal air and external air into said passenger compartment;
• and
• a scroll casing substantially horizontally disposed below said internal air/external air selector housing and including an air inlet to introduce said internal air and external air, wherein said blower includes a centrifugal fan contained within said scroll casing and which receives the air from the internal air/external air selector housing through said air inlet and which discharges the air in an approximately horizontal direction, said scroll casing including an air outlet connected to an air passage to said bottom of said cooling heat exchanger.
