An air conditioning unit for a vehicle has a casing, a heating heat exchanger, a first partition plate, a first opening, a second partition plate, a second opening, and a switching door. The casing has a face opening and a foot opening. The heating heat exchanger is arranged in the casing. The first partition plate partitions a downstream side of the heating heat exchanger in an airflow direction into a first passage and a second passage located below the first passage. The first opening is formed on a downstream side of the first partition plate in an airflow direction and communicates between the first passage and the second passage. The second partition plate is arranged on the downstream side of the heating heat exchanger and is formed with a third passage between the first partition plate and the second partition plate in the first passage. The second opening that is located on a downstream side of the second partition plate in an airflow direction and communicates between an upper side and a lower side of the second partition plate. The switching door opens or closes the first and second openings. The air in the third passage is guided toward the foot opening by the second partition plate and the switching door in an air conditioning mode in which the switching door opens the first opening and closes the second opening.

Air conditioning unit for vehicle

A vehicle air conditioner includes a blower for blowing air into a space of a vehicle compartment, and an air-conditioning mode switching portion for switching between air conditioning modes. The air conditioning modes include a normal air conditioning mode in which air conditioning of a specific region including a driver seat and air conditioning of a non-specific region not including the specific region in the space of the vehicle compartment are performed, and a specific-region prioritizing air conditioning mode in which an air conditioning capability for the non-specific region is decreased as compared to the normal air conditioning mode. The air-conditioning mode switching portion adjusts the air conditioning capability for the non-specific region based on a pressure of air drawn into the blower, in the specific-region prioritizing air conditioning mode.

Air conditioner for vehicle

In an interior air conditioning unit, a divided case is provided with a main water receiver, a main drain port, a side wall, a secondary drain port, a partition wall, a notch, a droplet reservoir, a path, and a tilted portion. The side wall, the secondary drain port, the notch, the droplet reservoir, the path, and the tilted portion are respectively located such that a condensate water flows out of the main water receiver and reaches the secondary drain port through the notch before a water surface of the condensate water reaches a fitting portion between the divided cases. According to the above-described configuration, the condensate water produced in the cooling heat exchanger can be certainly prevented from leaking through the fitting portion of the air conditioning case.

Air conditioning device for vehicle

A water discharge device that collects and drains condensed water generated in an air conditioning device includes: a drainage path along which condensed water is able to be drained in a draining state in which condensed water is expelled; and an opening and closing member that is able to block and open the drainage path. The opening and closing member blocks the drainage path so as to limit movement of air due to dynamic pressure when in a non-draining state other than the draining state. The opening and closing member drains condensed water through the drainage path when in the draining state.

Water discharge device and air conditioning device with same

A control part controls a first opening-and-closing part to close either one of a first outside air introduction port and a first inside air introduction port when it is determined that outside air introduced from the first outside air introduction port flows into a passenger compartment through the first inside air introduction port, and controls a second opening-and-closing part to close either one of a second outside air introduction port and a second inside air introduction port when it is determined that outside air introduced from the second outside air introduction port flows into the passenger compartment through the second inside air introduction port.

Air-conditioner for vehicle

An air conditioner ECU can set an external air introducing mode and an internal/external air dual mode. Here, the internal/external air dual mode is set by the air conditioner ECU in cases in which the air conditioner ECU judges that there is a warm-up state that is after a start of a heating operation and in which a blow-out temperature of air conditioned wind is in the process of rising, and in cases in which humidity detected by a humidity sensor exceeds a reference humidity that is set in advance.

Vehicle air conditioner

A vehicle air conditioner includes a heating heat exchanger, a first temperature adjustment mechanism for adjusting a temperature of air to be blown toward a driver's seat side in a vehicle compartment, and a second temperature adjustment mechanism for adjusting a temperature of air to be blown toward a front-passenger's seat side in the vehicle compartment. In the vehicle air conditioner, the first and second temperature adjustment mechanisms are controlled to perform a one-seat priority mode control such that the temperature of air to be blown toward the front-passenger's seat side is lower than the temperature of air to be blown toward the driver's seat side, when only the driver is in the vehicle compartment and the heating condition is determined as the air conditioning state.

When there is no occupant in seats other than a driver seat during a foot mode, an air-conditioning controller executes a single seat concentration mode to prevent blowing of warm air to a passenger seat and a backseat by closing foot outlets on a passenger seat side and a backseat side. In this case, in order to maintain an air volume blown from the foot outlet on a driver seat side when the controller changes the mode from the normal foot mode to the single seat concentration mode, the controller sets a blower level to be lower than in the case of the normal foot mode with respect to the same target blown air temperature.

Vehicular air conditioner

A humidity detecting apparatus includes a humidity sensor for detecting a relative humidity of air on an inner side of a window glass, an air temperature sensor for detecting a temperature of the air, a glass temperature sensor for detecting a temperature of the window glass, and a glass surface relative humidity calculation unit for calculating a glass surface relative humidity based on output values of the humidity sensor, the air temperature sensor and the glass temperature sensor. A heat conductive member is disposed between the glass temperature sensor and the window glass.
