Claim 0:
1. An air conditioner for a vehicle, comprising:
a battery as a power supply source of a motor for vehicle driving;
a compressor to compress a coolant;
a heat exchanger for heating to heat a cabin inside;
an external heat exchanger capable of introducing traveling air thereinto and to perform heat exchange between outside air and the coolant;
wherein the coolant compressed by the compressor passes through the heat exchanger for heating and then passes through the external heat exchanger;
an expansion valve for cooling and a heat exchanger for cooling which are provided to cool the cabin inside;
an expansion valve for battery and a heat exchanger for battery which are provided to cool the battery;
an opening/closing type of grille shutter to change an introduction state of the traveling air introduced into the external heat exchanger;
a pressure sensor proximal an outlet of the external heat exchanger to detect a pressure of the coolant which has been compressed by the compressor, then passed through the heat exchanger for heating, and then passed through the external heat exchanger, wherein the compressor, the heat exchanger for heating, the external heat exchanger, and the pressure sensor are arranged sequentially in that order with respect to a direction of flow of the coolant; and
a control unit to control opening/closing of the grille shutter,
wherein the coolant is shared among said heat exchanger for heating, said external heat exchanger, said heat exchanger for cooling, and said heat exchanger for battery, and said control unit is configured to make said grille shutter in a closed state when the pressure of the coolant detected by said pressure sensor is a specified pressure or lower.
