Vehicle air-conditioning system with independent left/right temperature control during maximum cooling

A vehicle air-conditioning system comprising:

• an air-conditioning case defining a ventilation path;
• a cooling heat exchanger disposed in the air-conditioning case for cooling air;
• a heating heat exchanger, disposed in the air-conditioning case on a downstream side of the cooling heat exchanger, for heating air;
• a bypass passage for bypassing air around said heat exchanger;
• a partition plate for partitioning the ventilation path into a right side ventilation path and a left side ventilation path at least on a downstream side of the heating heat exchanger;
• and
• right and left side temperature adjusters, respectively disposed in the right side ventilation path and the left side ventilation path, for controllably adjusting an amount of conditioned air heated by the heating heat exchanger and fed to respective right and left passenger compartment sides, said right and left side temperature adjusters being mixing devices;
• a blower that blows air through said heat exchanger, said right side ventilation path and said left side ventilation path;
• wherein when said left and right side temperature adjusters are in a maximum cooling state and the heat load in one of said left and right passenger compartment sides has a higher heat load than the other of said left and right passenger compartment sides, an air-blow amount provided by said blower is increased and an opening of one of said left and right side temperature adjusters corresponding to a cooler of said left and right passenger compartment sides is reduced.
