Air-conditioning apparatus for motor vehicles
First Claim
1. Air conditioning apparatus for conditioning the air supplied to a vehicle passenger space and the like, comprising:
- air inlet means;
an evaporator arranged downstream of the air inlet means and including means for cooling air passed therethrough;
evaporator inlet means supplying air from the air inlet means to the evaporator;
evaporator bypass duct means for conducting air from the air inlet means to a location downstream of the evaporator in bypassing relationship to the evaporator;
evaporator outlet guide means for guiding the flow of air away from the evaporator after it has been cooled therein, said evaporator outlet guide means including first deflector plate means for guiding air from the evaporator to the outlet of the evaporator bypass duct means;
first temperature mixing valve means for controlling the proportion of air supplied from the air inlet means to the respective evaporator and evaporator bypass duct means;
a heat exchanger arranged downstream of the evaporator and evaporator bypass duct means and including means for heating air passed therethrough;
heat exchangers inlet duct means for guiding air from the evaporator and the evaporator bypass duct means to the heat exchanger;
heat exchanger bypass duct means for conducting air from the evaporator and evaporator bypass duct means to a location downstream of the heat exchanger in bypassing relationship to the heat exchanger;
heat exchanger outlet guide means for guiding the flow of air away from the heat exchanger after it has been heated therein to a location where it is mixed with the air from the heat exchanger bypass duct means, said heat exchanger outlet guide means including second deflector plate means; and
second temperature mixing valve means for controlling the proportion of air supplied from the evaporator and evaporator bypass duct means to the respective heat exchanger and heat exchanger bypass duct means;
wherein said heat exchanger inlet duct means includes a third deflector plate means and wherein the respective sides of the first and third deflector plate means facing respectively away from the evaporator and heat exchanger form a cool air duct for directing air to the vehicle passenger space in bypassing relationship to both the heat exchanger and the heat exchanger bypass duct means.

Abstract
Air conditioning apparatus for conditioning the air supplied to a vehicle passenger space is provided which includes an air conditioning air cooling evaporator and an air heater unit arranged in series. An evaporator bypass duct extends in bypassing relationship to the evaporator and a heater bypass duct extends in bypassing relationship to the heater. To control the temperature of the air conditioned by the apparatus two temperature mixing air flaps are provided, one air flap controlling the proportion of air flow through the evaporator and its bypass duct and the other air flap controlling the proportion of air through the heater and its bypass duct.
