Patent ID: 8042746

Claim:
A vehicular air conditioner comprising: a plurality of air conditioner units, each comprising; heat supply amount setting means for setting a heat supply amount; a heat generator and a cooled heat generator; and drive control means for controlling operations of the heat generator and the cooled heat generator, based on the heat supply amount set by the heat supply amount setting means, wherein a heat amount is supplied to an interior of a vehicle by the plurality of air conditioner units being operated in combination, the heat supply amount setting means comprises: a total heat supply amount calculation portion for calculating a total heat supply amount command value of the plurality of air conditioner units, based on a target temperature and an actual room temperature; and a generated heat amount/cooled heat amount setting portion for setting generated heat amounts of the heat generator and the cooled heat generator of each of the air conditioner units, based on the total heat supply amount command value and the number of the air conditioner units, wherein each of the air conditioner units holds operation go/no-go information as to whether the heat generator and the cooled heat generator owned thereby is each permitted to operate, and has an operation go/no-go information holding portion that exchanges the operation go/no-go information with the other air conditioner units; and the generated heat amount/cooled heat amount setting portion of each air conditioner unit sets generated heat amounts of the heat generator and the cooled heat generator based on a setting pattern set for each air conditioner unit, wherein when the heat supply amount command value is less than a predetermined cooled heat amount, the setting pattern is set so that the cooled heat generator of a certain air conditioner unit is operated in a predetermined lowest set value and cooled heat generators of the other air conditioner units are suspended, and, a generated heat amount of the heat generator of each air conditioner unit that is operable is set to be the same.
