AIR CONDITIONER FOR VEHICLE
First Claim
1. An air conditioner for a vehicle having an in-vehicle equipment which outputs heating energy for heating air to be blown into a vehicle compartment of the vehicle, in which a temperature of the in-vehicle equipment is adjusted to be within a predetermined standard range, and an operational efficiency (η
- e) of the in-vehicle equipment is controlled such that a fuel consumption of the in-vehicle equipment approaches a smallest amount when the in-vehicle equipment is operated, the air conditioner comprising;
a first heating portion arranged in a circulation circuit through which a heat medium heated by waste heat of the in-vehicle equipment circulates, the first heating portion heating air to be blown into the vehicle compartment by using the heat medium as a heat source;
a second heating portion configured to heat the blown air by using the heating energy outputted from the in-vehicle equipment;
a determination portion configured to determine a target heat amount ratio that is a target value of a heat amount ratio (hm2/hm1), the heat amount ratio (hm2/hm1) being a ratio of a second heat amount (hm2) used for heating the blown air in the second heating portion to a first heat amount (hm1) used for heating the blown air in the first heating portion; and
a heating adjustment portion configured to adjust at least one of the first heat amount (hm1) and the second heat amount (hm2) such that the heat amount ratio (hm2/hm1) approaches the target heat amount ratio, whereinthe determination portion causes the target heat amount ratio to be increased in accordance with an increase of the operational efficiency (η
e).

Abstract
An air conditioner for a vehicle in which an operational efficiency of an in-vehicle equipment is controlled, includes a first heating portion which heats air to be blown into a vehicle compartment by using heat medium, a second heating portion which heats the blown air by using heating energy outputted from the in-vehicle equipment, a determination portion which determines a target heat amount ratio that is a target value of a heating amount ratio of a second heat amount used in the second heating portion to a first heat amount used in the first heating portion, and a heating adjustment portion which adjusts at least one of the first and second heat amounts such that the heat amount ratio approaches the target heat amount ratio. The target heat amount ratio is increased in accordance with an increase of the operational efficiency.
