Appl. No.:

11/223627

Inventors:

Munther M. Salim - Macomb MI, US

Jeffrey A Bozeman - Rochester MI, US

Assignee:

General Motors Corporation - Detroit MI

International Classification:

B60H 1/32

US Classification:

62139, 62244

Abstract:

The present invention concerns a method for cooling a passenger compartment in a hybrid vehicle that operates an engine intermittently during vehicle operation, the hybrid vehicle having an HVAC system including an HVAC duct, a blower adapted to direct a flow of air through the HVAC duct, and an evaporator located within the HVAC duct. The method includes the steps of operating the blower; operating the compressor; allowing a predetermined amount of ice to form on the evaporator during operation of the compressor; turning off the vehicle engine; ceasing operation of the compressor; measuring an indicator corresponding to a remaining amount of the predetermined amount of ice formed on the evaporator; and re-starting the compressor when a predetermined air temp in air duct is reached.

Abstract:

Accordingly, a control system for controlling a viscous clutch of a fan is provided. The control system includes a delta speed module that determines one of an over speed condition, an under speed condition, and a steady state condition based on a desired fan speed and an actual fan speed. A mode module determines a mode of the clutch based on the one of the over-speed condition, the under-speed condition, and the steady state condition, wherein the mode is one of a pump in mode, a pump out mode, and a closed loop mode. A valve control module that controls an operational state of the clutch valve based on the mode.

International Classification:

F25B 29/00
F25B 27/00

US Classification:

622386

Abstract:

A climate control system for a vehicle with a passenger compartment includes a heater circuit, a cooler circuit, and a primary loop, all of which have fixed flow directions. The heater circuit is filled with a first liquid medium and has a heater core, and the cooler circuit is filled with a second liquid medium and has a cooler core. The heater and cooler cores are selectively in thermal communication with the passenger compartment. The primary loop includes a compressor and an expansion valve and is filled with a refrigerant medium. No portion of the primary loop is within the passenger compartment. A liquid-cooled condenser thermally links the heater circuit and primary loop. A liquid-warmed evaporator thermally links the cooler circuit and primary loop. The primary loop is in direct heat-exchange communication with one of the first liquid medium and the second liquid medium.

International Classification:

H01M 8/04291
H01M 8/22

Abstract:

Presented are fuel cell systems and control logic for extracting water from system exhaust, methods for making/using such systems, and electric-drive vehicles with aftertreatment systems for extracting water from fuel cell exhaust. An aftertreatment system for a fuel cell stack includes a condensate generator that fluidly connects to the fuel cell stack to receive exhaust output therefrom. The condensate generator includes an evaporator core with a refrigerant line that actively cool the exhaust via controlled circulation of refrigerant fluid. A condensate collector fluidly connected to the condensate generator includes a reservoir housing with a condensate trap that separates entrained water vapor from the cooled exhaust. The reservoir housing collects the separated water vapor as liquid water. A liquid storage container fluidly connected to the condensate collector receives and stores the collected water. An expansion valve regulates the amount of refrigerant fluid passed into the evaporator core through the refrigerant line.

International Classification:

B60H 1/00

Abstract:

A vehicle HVAC system includes a component within a refrigerant system in a vehicle HVAC system, a vibration sensor that generates a vibration signal indicating a vibration of the component, and a controller in communication with the vibration sensor to receive the vibration signal and the refrigerant system. The controller is configured to determine whether the vibration signal corresponds to a predetermined vibration value and for adjusting the operation of the refrigerant system to minimize the system noise if the vibration signal corresponds to the predetermined vibration value.
