Air conditioning apparatus for vehicle

An air conditioning apparatus for a vehicle having a passenger compartment, comprising:

• a cooler unit having a first case forming a first air passage for introducing air toward the upper half body of a passenger in said passenger compartment, first air blowing means for blowing air in said first air passage, and a first heat exchanger for cooling air blown from said first air blowing means;
• a heater unit having a second case forming a second air passage for introducing air toward feet of said passenger in said passenger compartment, second air blowing means for blowing air in said second air passage, and a second heat exchanger for heating air blown from said second air blowing means;
• second air blowing stopping means for stopping said second air blowing means when said passenger compartment is rapidly heated and a heating capacity of said second heat exchanger is less than a predetermined capacity;
• control means for gradually increasing an air blowing capacity of said second air blowing means according to a rise of said heating capacity when said heating capacity reaches said predetermined capacity while stopping said second air blowing means;
• and
• first air blowing stopping means for stopping said first air blowing means when both of said cooler unit and said heater unit are operated and when said passenger compartment is rapidly heated and a heating capacity of said second heat exchanger is less than a predetermined capacity.
