摘要: The disclosure relates to a blower assembly having a blower housing, an impeller adapted for rotation about an axis A-A disposed in blower housing, and an intake plenum cooperating with the interior first surface of the blower housing to define an air entrance passage for receiving an incoming air flow. The intake plenum includes means to split the incoming air flow into a plurality of air streams and direct the air streams to predetermined portions of the impeller susceptible to stall conditions as the impeller rotates about the axis A-A. The means to split the incoming air may include a splitter plate disposed in the air entrance passage or at least one port defined in a portion of the air intake plenum adjacent the impeller.

摘要: An automotive HVAC system includes upper and lower mode cases configured to discharge separate streams of temperature-conditioned air into front and rear passenger zones. The system separates the inlet air into separate mixing chambers, and a third stream through a heater core. Blend doors control hot and cold air streams entering their respective mixing chambers. Operation is controlled by reading requested temperature, blower rate and mode for system zone outlet, converting requests to a flowrate, calculating total flowrate as a summation of all requests, employing a math model to calculate total zonal flowrate as a summation of all zonal flowrates, calculating a blower control error as a function of the difference between total blower request and total zonal flowrate, modifying the operating state using the calculated control error, positioning and resetting the mode valves into defrost, heater and vent openings, and resetting the mode valves.

摘要: A heating, ventilation, and air conditioning (HVAC) system for a vehicle includes an evaporator and a diffuser. The evaporator is configured to cool air passing through the evaporator. The diffuser is configured to direct a first portion of the air entering the diffuser through a first section of the evaporator, and direct a second portion of the air entering the diffuser through a second section of the evaporator. The evaporator and the diffuser are configured to cooperate such that air exits the first section at a first temperature and air exits the second section at a second temperature less than the first temperature.

摘要: An open architecture HVAC module is disclosed having a housing defining an air inlet and at least two adjacent air outlets. An evaporator and a heater unit are disposed within the housing. A cold air chamber is defined between the evaporator and heater unit, and a hot air chamber is defined downstream of the heater unit. A partition extends into the cold and hot air chambers from an interior surface of the housing between the two adjacent air outlets. The partition is spaced from the evaporator and heater unit. The partition cooperates with the housing to define a first mixing chamber in fluid communication with the first outlet and a second mixing chamber in fluid communication with the second outlet. A blend valve is disposed in each mixing chambers. The blend valves are configured to selectively direct air flow from the cold and hot air chambers to the air outlets.
