An air conditioner for a vehicle including a case body having a floor outlet, a roof outlet, an evaporator, and a heater core; a mode door adjusting an opening amount of each of the vents; and a temp door adjusting an opening amount of a cold-air passage and a hot-air passage, includes: an actuator lever connected to an actuator provided in the case body, and a main lever connected to the actuator lever to simultaneously control the mode door and the temp door.

A heating, ventilation, and air conditioning (HVAC) door assembly includes a first HVAC door rotating about a first axis, a second HVAC door rotating about a second axis that is nonparallel with the first axis, an actuator, a mode cam. The mode cam is engaged with the actuator and controls movement of the first HVAC door and the second HVAC door.

A shipping container is provided and includes a structural frame defining an interior, a transport refrigeration unit (TRU) and a control system. The TRU includes an inlet through which air is drawn from a lower region of the interior, a refrigeration unit configured to cool the air drawn from the lower region of the interior through the inlet and an outlet through which air cooled by the refrigeration unit is exhausted toward an upper region of the interior. The control system is configured to control an exhaustion of the air cooled by the refrigeration unit toward the upper region of the interior to maintain a predefined environmental condition within the interior.

An air-handling system for a heating, ventilation, and air conditioning system of a vehicle includes a main housing comprising a conditioning section, a mixing section, and a delivery section having a flow of air passing therethrough. The delivery section includes a conduit branching into a windshield defrost pathway and a demist pathway, the windshield defrost pathway leading to windshield defrost vents of a passenger compartment of the vehicle and the demist pathway leading to side window defrost vents of the passenger compartment. A control door rotatably disposed in the conduit is adjustable through a range of rotational positions wherein a flow area through the windshield defrost pathway is variably restricted while the demist pathway remains unobstructed. The control door is further adjustable to a position wherein the windshield defrost pathway and the demist pathway are closed.

The present disclosure provides a power transmission device in which stress is reduced and a vehicle air-conditioning device. An air-conditioning device has an inside/outside air door. A power transmission device drives the inside/outside air door. The power transmission device has a motor, a gear train, and a cam mechanism. A first gear of the gear train provides a rotatable member. A plurality of lock mechanisms is provided, which stops a rotation of the first gear at one end and/or the other end in a rotation direction of the first gear. The plurality of lock mechanisms provide a plurality of contacts between the first gear and a stationary link cover.

A system for controlling airflow of a heating, ventilation, and air conditioning (HVAC) system. The system includes a register including airflow directionals. A motor is connected to the register to move the directionals. A directionals selector is connected to the motor to control the motor. Actuation of the directionals selector by a user changes position of the directionals. A control module stores predetermined positions of the directionals, and controls the motor to move the directionals to the predetermined positions in response to receipt of a user command.

A vehicle includes an exterior surface, a sensor disposed on the exterior surface, a passenger cabin fixed relative to the exterior surface, a duct receiving airflow from the passenger cabin, and a valve disposed in the duct and movable between a first position directing the airflow to the sensor and a second position directing the airflow outside the vehicle.

A heating, ventilation, and air conditioning (HVAC) system including an HVAC assembly, a set of pins, mode doors, a mode plate, an actuator, and an HVAC control module. The mode doors control airflow from the HVAC assembly. A position of each mode door is controlled by a corresponding pin of the set of pins. The mode plate includes (i) a set of grooves, (ii) a first adjustment path and (iii) a second adjustment path. The first adjustment path causes a first pin of the set of pins to move toward a center. The second adjustment path causes the first pin to move away from the center of the mode plate. An HVAC module selectively actuates the actuator to causes the mode plate to rotate in at least one of a passive direction and the active direction in response to receiving a mode request.

There is disclosed a vehicle air conditioner which is capable of enlarging an effective range of a dehumidifying and heating mode to environmental conditions and smoothly dehumidifying and heating a vehicle interior. A vehicle air conditioner 1 executes a dehumidifying and heating mode in which a controller lets a refrigerant discharged from a compressor 2 radiate heat in a radiator 4, and decompresses the refrigerant by which heat has been radiated and then lets the refrigerant absorb heat in a heat absorber 9 and an outdoor heat exchanger 7, the controller decreases an outdoor blower voltage FANVout of an outdoor blower 15 and decreases an air volume into the outdoor blower 15 in a case where a temperature Te of the heat absorber 9 is high even when the controller adjusts a valve position of an outdoor expansion valve 6 into a lower limit of controlling in a situation in which a temperature TCI of the radiator 4 is satisfactory.

A vehicle air conditioner includes: a condenser that internally circulates a high-temperature and high-pressure refrigerant which is discharged from a compressor and that heats air passing around the condenser; an evaporator that internally circulates a low-temperature and low-pressure refrigerant and that absorbs heat from the air passing around the evaporator; and a switching portion that switches flows of air in response to a heating time, a cooling time, and a dehumidifying-heating time of a vehicle. Also, the switching portion causes the air passing around the condenser to flow into a vehicle compartment during the heating time of the vehicle, causes the air passing around the evaporator to flow into the vehicle compartment during the cooling time of the vehicle and causes the air sequentially passing through the evaporator and the condenser to flow into the vehicle compartment during the dehumidifying-heating time of the vehicle.
