International Classification:

F01P 9/00

US Classification:

123 4101, 123 4131, 1231425 E, 237 123 B, 180 652, 165 41

Abstract:

An air separator for low flow rate coolant systems which removes air from the liquid coolant thereof. The air separator is a closed canister having a bottom wall, a top wall at a gravitationally high location with respect to the bottom wall, and a sidewall sealingly therebetween. A coolant inlet is at the sidewall, a pump outlet is at the bottom wall and a coolant reservoir outlet is at the top wall. The coolant reservoir outlet is connected to a coolant reservoir gravitationally elevated with respect to the canister. A much larger cross-sectional area per unit length of the canister relative to the piping results in a coolant dwell time in the canister that encourages coolant air bubbles to migrate toward the coolant reservoir.

Abstract:

The present invention concerns a method for pre-cooling the passenger compartment of an automotive vehicle. The vehicle includes at least one electrically actuatable window and a HVAC system having at least a controller, a blower, a passenger compartment temperature sensor, and a HVAC ducting leading to the passenger compartment. The controller and the blower are connected to a vehicle battery. The method includes determining the passenger compartment temperature and comparing the temperature to a first predetermined value; cycling an blower inlet to an outside air intake position and operating the blower to provide pressurized air to the passenger compartment if the passenger compartment temperature is greater than the first predetermined value; opening the vehicle windows; comparing the passenger compartment temperature to a second predetermined value; and stopping operation of the blower when the passenger compartment temperature drops below the second predetermined value.

International Classification:

F01P 3/00

US Classification:

123 4151

Abstract:

An integrated high and moderate temperature cooling system both for an internal combustion engine and for auxiliary vehicle components requiring cooling. The integrated cooling system shares a coolant, yet the shared coolant is stratified to retain thermal identity between the portion of the coolant used for engine cooling and the portion of the coolant used for auxiliary vehicle components cooling. A shared coolant reservoir is used; preferably a shared heat exchanger, and optionally a common coolant pump may also be used.

US Classification:

165 42, 165 43

Abstract:

A HVAC and RESS thermal management system and a method of operation for a vehicle having a passenger compartment, a power plant and a battery pack is disclosed. The system comprises a RESS coolant circuit and a power plant coolant circuit. The RESS coolant circuit directs a coolant through the battery pack and includes a pump, a coolant heating branch has a coolant-to-coolant heat exchanger, and a coolant routing valve that will selectively direct the coolant through the coolant heating branch. The power plant coolant circuit includes a heater core branch having a HVAC pump, a coolant heater, a heater core located in a HVAC module to provide heat to the passenger compartment, and the coolant-to-coolant heat exchanger, with the coolant-to-coolant heat exchanger providing heat transfer between the coolant in the coolant heating branch and the coolant in the heater core branch.

Abstract:

A system and method for providing cool air to a passenger compartment of a hybrid vehicle in an engine off mode is disclosed. This may include operating a HVAC system to provide cold refrigerant flowing through an evaporator while an engine is operating, and forcing air through the evaporator to cool the air. A first portion of the cooled air from the evaporator is directed through a heater core and a second portion around the heater core, and an electric water pump is activated to pump coolant from a thermal storage tank, through the heater core and back to the thermal storage tank to cool the coolant. When the engine operation is ceased, the air flow is directed through the heater core, and the coolant is pumped from the thermal storage tank, through the heater core and back to the thermal storage tank to cool the air.
