Air conditioner

Abstract

The air suction mode can be switched among the inside air mode in which the air sucked by the battery cooling blower 15 to cool the battery 3 for vehicle use is the air inside a vehicle passenger compartment, the outside air mode in which the air sucked by the battery cooling blower 15 is the air outside the vehicle passenger compartment and the cooling air mode in which the air sucked by the battery cooling blower 15 is the air cooled by an evaporator of the rear seat side air conditioner 2.

1 . An air conditioner for vehicle use comprising:
 an air-conditioning unit including a cooling air generation means for generating cooling air by cooling the passing air, a heating air generation means for generating heating air by heating the passing air, a conditioned air generation means for generating conditioned air by mixing the cooling air and the heating air by a ratio of the hot air to the cold air, and an air-conditioning blower for generating conditioned blowout air blowing out to a passenger in a vehicle passenger compartment;   a battery cooling unit including a battery cooling blower, which sucks the cooling air, for generating a flow of battery cooling air to be blown out to a battery mounted on a vehicle; and   a control unit including a conditioned air ratio calculating means for calculating a ratio of the hot air to the cold air, a correction means for correcting at least one of the ratio of the hot air to the cold air and the conditioned air volume level according to the battery cooling air volume level, a conditioned air volume level control means for controlling a conditioned air volume level which is the air volume level of the conditioned air blown out, and a battery air volume level control means for controlling a battery cooling air volume level which is an air volume level of the battery cooling air blown out.   
   
   
       2 . An air conditioner for vehicle use according to  claim 1 , wherein the correction means for correcting the ratio of the hot air to the cold air conducts a correction so that a ratio of the cooling air in the conditioned air can be increased according to an increase in the battery cooling air volume level. 
   
   
       3 . An air conditioner for vehicle use according to  claim 1 , wherein the correction means for correcting the conditioned air volume level conducts a correction so that the conditioned air volume level can be increased according to an increase in the battery cooling air volume level. 
   
   
       4 . An air conditioner for vehicle use comprising:
 an air-conditioning unit including a cooling air generation means for generating cooling air by cooling the passing air, a heating air generation means for generating heating air by heating the passing air, a conditioned air generation means for generating conditioned air by mixing the cooling air and the heating air by a ratio of the hot air to the cold air, an air-conditioning blower for generating conditioned blowout air blowing out to a passenger in a vehicle passenger compartment, and a conditioned air blowout temperature detection means for detecting a conditioned air blowout temperature which is a temperature of the conditioned blowout air;   a battery cooling unit including a battery cooling blower for generating a flow of battery cooling air to be blown out to a battery mounted on a vehicle, and a mode switching means for switching a mode between the inside air mode, in which the sucked air is the inside air in the vehicle passenger compartment according to the battery temperature, and the cooling air mode in which the suction air is the cooling air; and   a control unit including a conditioned air ratio calculating means for calculating the ratio of the hot air to the cold air, a conditioned air volume level control means for controlling a conditioned air volume level which is an air volume level of the conditioned blowout air, and a battery air volume level control means for controlling a battery cooling air volume level which is an air volume level of the battery cooling blowout air, wherein   the battery air volume level control means reduces the battery cooling air volume level to a value not more than the predetermined value at the time of switching the mode, and the battery air volume level control means further reduces a change rate of the battery cooling air volume level in the case where the change rate of the conditioned blowout air temperature exceeds the predetermined value.   
   
   
       5 . An air conditioner for vehicle use according to  claim 4 , wherein the battery air volume level control means stops the battery cooling blower at the time of switching the mode. 
   
   
       6 . An air conditioner for vehicle use according to  claim 4 , wherein the mode switching means is capable of adjusting a switching rate of switching the mode.
