Abstract: To provide an air conditioner for a vehicle includes an evaporator, a heater core, an air conditioning passage, an inside air introduction passage, an outside air introduction passage, and a heat pipe. In the air conditioning passage, a ventilation portion of the heater core is disposed downstream from a ventilation portion of the evaporator. Through the heat pipe, heat is transferred from a high temperature portion on the inside air introduction passage side to a low temperature portion on the outside air introduction passage side due to evaporation and condensation of a refrigerant. The heat pipe is provided in the evaporator to straddle a position facing the inside air introduction passage and a position facing the outside air introduction passage.

Abstract: A front and rear integrated vehicle HVAC system includes a front HVAC portion with a front blower and a front vent outlet, and a rear HVAC portion with a rear blower and a rear vent outlet. The system includes a controller that determines a minimum voltage to be supplied to the rear blower to prevent an inverse air flow from being expelled from the rear outlet and/or a rear blower air intake. A voltage supplied to the rear blower is then set as the greater of the minimum rear blower voltage and a current rear blower voltage. The inverse air flow is air flow in the front HVAC portion generated by the front blower and intended for the front vent outlet that seeps into the rear HVAC portion and is expelled from the rear vent outlet and/or the rear blower air intake.

Abstract: The disclosure provides a solvent separation system and a solvent separation method using the solvent separation system.

Abstract: A cooling storage evaporator system employs a pivoting frost control door upstream from an evaporator that, when closed, inhibits air from passing through a lower portion of the evaporator. Closing the frost control door results in condensed water freezing on a lower portion of the evaporator when the AC is ON. When a vehicle engine is turned OFF when the vehicle stops in an idle condition, thereby turning the compressor OFF, the frost control door opens so that air passes over the evaporator, including the frozen portion thereof, melting the frozen condensed water to maintain the cool outlet air temperature at the vent.

Abstract: A vehicle air conditioner includes a first passage and a second passage and is capable of operating in such a manner that outside air introduced in the first passage is conditioned by an evaporator and a heater core and subsequently blown, as a conditioned air, from a defrost outlet, side defrost outlet and side vent outlet toward windowpanes and, at the same time, inside air introduced in the second passage is conditioned by the evaporator and the heater core and subsequently blown, as a conditioned air, from a center vent outlet and front and rear heat outlets into a passenger compartment.

Abstract: A dual-integrated HVAC system for an automotive vehicle is provided that includes a housing, a front HVAC unit with a front blower, and rear HVAC unit with a rear blower whereby both the front and rear HVAC units are housed in the housing. The front blower generates an airflow through a front airflow path and the rear blower generates an airflow through a rear airflow path. A separating wall separates the front airflow path from the rear airflow path. The HVAC system further includes an evaporator with a first portion in the front airflow path, a second portion in the rear airflow path, and a seal situated between the first portion and the second portion.

Abstract: In a vehicular air conditioning apparatus, a pair of covers are provided on the respective sides of the casing that is constituted by respective air passages. The covers rotatably support a pivot shaft for a defroster damper and a pivot shaft for a sub-defroster damper. The sub-defroster damper is disposed in a passage directly connecting the heater core with the defroster blow-out port, and is disposed on an upstream side of the defroster damper. First and second blower units supply air into the casing. The sub-defroster damper is disposed so as to face a passage which is disposed even inside the casing. Thus, the flowing direction and the amount of air is adjusted.

Abstract: A blower unit for a vehicle HVAC system, which is operable in one of a fresh air mode, a recirculation air mode and a mixture mode, comprises a housing defining an exterior fresh air intake aperture and an interior recirculation air intake aperture. A suction passage is in communication with both the exterior and interior air intake apertures. A first door is operably associated with the exterior air intake aperture for selectively opening and closing the exterior air intake aperture. A second door operably associated with the interior air intake aperture for selectively opening and closing the interior air intake aperture. The first and second doors are movable independent of each other. A partition is located in the suction passage for at least partially dividing the suction passage. The partition is selectively engaged by at least one of the first and second doors depending on the mode of the HVAC system.

Abstract: An HVAC system is provided and includes an evaporator for providing cold air and a heater core for providing hot air. A heater airflow path directs an airflow through a heater air outlet where a heater damper door controls the volume of the airflow through the heater air outlet. A defroster airflow path directs an airflow through a defroster air outlet and a defroster damper door controls the volume of the airflow through the defroster air outlet. The defroster damper door operates independently from the heater damper door. A separation channel is located between the heater airflow path and the defroster airflow path to separate the airflow of the heater airflow path from the airflow of the defroster airflow path.

On a lower portion of the casing, a second blower unit different from the first blower unit is connected. A center plate is disposed centrally in a lateral direction of the casing. Air is supplied from the first blower unit to the interior of the casing, whereby cool air cooled by an evaporator and warm air heated by a heater core are mixed together and blown respectively and separately to a driver's seat side and a passenger seat side of the front seats. Also, Air supplied from the second blower unit to the interior of the casing, after being adjusted to a predetermined temperature in the evaporator and the heater core, is supplied to a rear seat side of the vehicle.

Abstract: In a vehicular air conditioning apparatus, a first blower unit is connected by a connection duct to a side portion of a casing having respective air passages defined therein. In addition, air that is supplied to the interior of the casing from the first blower unit, and which is heated by the heater core, is blown from the fifth front passage alongside the heater core directly into the sixth front passage via sub-defroster dampers, and is blown out toward the front seat of the vehicle from a defroster blow-out port, which is disposed in the sixth front passage.

Abstract: In a vehicular air conditioning apparatus, a first partitioning member and a second partitioning member are installed at a boundary position between a first cooling section and a second cooling section of an evaporator. The evaporator is separated into the first cooling section and the second cooling section by the first and second partitioning members. In the case that air is not blown in either one of the passages that are disposed in the first cooling section and the second cooling section, air that flows through the other of the passages is prevented from flowing into the one passage through the interior of the evaporator.

Abstract: A method and apparatus for operating a vehicle HVAC system includes detecting an elevated risk of water splash expulsion from an evaporator through a vent outlet and controlling a voltage supplied to at least one blower of the vehicle HVAC system to reduce a risk of water splash expulsion if the elevated risk is detected. Water splash risk is determined in view of a voltage supplied to a subject blower, a vehicle tilt angle, and a condensation risk or value. The condensation risk or value is determined in view of a window open/close value, a temperature value, and a humidity value. Each of these factors are, either independently or in combination, compared with a corresponding threshold value to determine if the water splash risk warrants voltage control.
