An air conditioner for a vehicle, including: a discharge capability control section that controls refrigerant discharge capability of a compressor; an upper limit value determination section that determines an upper limit value of the refrigerant discharge capability; and a gear shift position detection section that determines a gear shift position of a gear shift device of a vehicle, wherein the gear shift device having a forward range for moving the vehicle forward and a range other than the forward range as the gear shift position; when the gear shift position determined by the gear shift position detection section is in a range other than the forward range, the upper limit value determination section decreases the upper limit value compared to when the gear shift position determined by the gear shift position detection section is in the forward range.

An electric motor-driven compressor is positioned closer to the center of gravity of an engine than a compression mechanism, and is mounted in such a manner that an axial direction of an electric motor is parallel to a crank shaft of the engine. Therefore, a vibration force produced by the engine and applied to the electric motor is reduced.

In an air conditioning apparatus for a vehicle, a double layer flow mode is set when the maximum heating state is set during an air outlet mode where both a foot opening portion and a defroster opening portion are opened. During the double layer flow mode, an air passage of an air conditioning case is partitioned into a first air passage through which inside air flows and a second air passage through which outside air flows, in such a manner that the first air passage communicates with the foot opening portion and the second air passage communicates with the defroster opening portion. When the double layer flow mode is set, the maximum rotation speed of a blower for blowing air is reduced by a predetermined level as compared with an entire outside air mode or an entire inside air mode. Thus, heating capacity for a passenger compartment of the vehicle can be improved.

An air conditioning apparatus for a vehicle includes an air conditioning case for forming an air passage through which air is blown into a passenger compartment. In the air conditioning apparatus, during a cooling mode for cooling a passenger compartment, an inside/outside air introduction mode is switched from an inside/outside air-mixing mode where both inside air and outside air are introduced into the air conditioning case to an entire outside air mode where only outside air is introduced into the air conditioning case, when an engine of the vehicle is stopped and the cooling load is smaller than a predetermined cooling load. Therefore, air-suction noise from an inside air introduction port is not caused, and the air-suction noise is not noted by a passenger in the passenger compartment even when the engine is stopped. Thus, noise of the air conditioning apparatus in the passenger compartment can be reduced.

An air conditioner for a vehicle having an electric motor for traveling and an internal combustion engine as driving sources for outputting a driving force for causing the vehicle to travel, the air conditioner including: a heating section that heats blown air to be blown into a vehicle interior by using a coolant of the internal combustion engine as a heat source; a request signal output section that outputs a request signal to a driving force control section in heating the vehicle interior, the driving force control section controlling an operation of the internal combustion engine, the request signal causing the internal combustion engine to operate until a temperature of the coolant reaches an upper limit temperature; and a suppression section for suppressing output of the request signal from the request signal output section until a predetermined condition is satisfied after startup of the vehicle.

A blower unit includes a centrifugal fan, a fan casing forming a scroll-shaped air passage and accommodating the centrifugal fan, and a partition wall for partitioning an interior of the fan casing into first and second air passages in which different kinds of airs flow, respectively, in the axial direction. The partition wall is molded integrally to the fan casing so as to extend linearly from the inner wall surface of the fan casing toward a radial inside of the fan. The fan casing includes two divided cases having a divided face in the axial direction. In this way, the number of divided cases can be as well as the number of steps of assembling the fan casing can be reduced so that the work efficiency for assembling the fan casing is improved.

摘要:
A motor vehicle air conditioner that is operative to cause the quantity of conditioned air to change smoothly when an air conditioner bypass passage is opened/closed. When a user switches a typical automotive air conditioner between a bi-level flow mode and a full outer-air mode, a warm-air bypass door does not stop at an intermediate position, thus causing both air quantity of conditioned air and blown-air temperature of conditioned air to change greatly. In the air conditioner of the present invention, the air conditioner warm-air bypass door stops once at an intermediate position, thus enabling the air quantity of the conditioned air and the temperature change in the blown-air to change gradually.

According to the present invention, in an air conditioning apparatus setting a double laminar mode in which inside air and outside air are blown while being partitioned, when the maximum heating state (including the high heating capacity close to the maximum heating operation) is set, a warm air bypass door for introducing warm air directly into a foot opening portion, without being mixed into cool air, functions as a movable partition member for partitioning an air passage at a downstream side of a heating heat exchanger, into an inside air passage and an outside air passage. In this way, it is possible to downsize the air conditioning unit.
摘要:
An electric power unit is composed of a secondary battery, a cooling fan, a fan motor and a case for the secondary battery, the cooling fan and the fan motor. The case has a partition for isolating the fan motor from the secondary battery and cooling fan. A magnetic joint is disposed between the motor and the cooling fan.
