The HVAC system also comprises a water tank that receives and stores water, a water spray pump that receives water from the water tank, and a nozzle that receives water from the water spray pump and is located adjacent to the condenser, with the nozzle selectively spraying water on the fins of the condenser. | 12-09-2010 |
20110067389 | VEHICLE EXHAUST HEAT RECOVERY SYSTEM AND METHOD OF MANAGING EXHAUST HEAT - An exhaust heat recovery system (EHRS) for a vehicle is operable to direct exhaust heat to a vehicle transmission under certain operating conditions. In some embodiments, the EHRS may also direct exhaust heat to a heater for vehicle passenger compartment. Preferably, the EHRS is controllable to manage available exhaust heat according to vehicle operating conditions, by prioritizing the heat flow among the engine, the transmission, and the vehicle heater. The EHRS may also operate in a bypass mode during which exhaust heat is not directed to the engine, the transmission or the vehicle heater. A method of managing exhaust heat recovery on a vehicle having an EHRS is also provided. | 03-24-2011 |
20110088378 | EXHAUST HEAT RECOVERY FOR TRANSMISSION WARM-UP - An exhaust heat recovery system (EHRS) for a vehicle is provided that is operable to direct coolant heated by exhaust heat to a vehicle transmission under certain operating conditions after the engine is adequately heated by the exhaust heat and without further heating the engine with the exhaust heat. Thus, recovery of exhaust heat is increased as the transmission is heated to a higher operating temperature than the engine using the heated coolant. The EHRS may also operate in a bypass mode during which exhaust heat is not directed to the engine or the transmission. A method of managing exhaust heat is also provided. | 04-21-2011 |
20110091750 | Temperature Control of a Vehicle Battery - The method for thermal management of a battery can include vehicle systems to control the thermal input to the battery and a dedicated battery thermal management system. The battery thermal management system includes transferring battery heat to coolant flowing in a circuit, if ambient air temperature is greater than the battery temperature, using an evaporator/chiller to transfer heat from the coolant to a refrigerant, using a condenser to transfer heat from the refrigerant to the coolant, and using a radiator to transfer heat from the coolant to ambient air; and if coolant can be maintained in the reference temperature range without using a heat source or refrigerant, using a radiator to transfer heat from the coolant to the ambient air. | 04-21-2011 |
20120143437 | METHOD FOR CONTROLLING EXHAUST GAS HEAT RECOVERY SYSTEMS IN VEHICLES - A method of operating a vehicle including an engine, a transmission, an exhaust gas heat recovery (EGHR) heat exchanger, and an oil-to-water heat exchanger providing selective heat-exchange communication between the engine and transmission. The method includes controlling a two-way valve, which is configured to be set to one of an engine position and a transmission position. The engine position allows heat-exchange communication between the EGHR heat exchanger and the engine, but does not allow heat-exchange communication between the EGHR heat exchanger and the oil-to-water heat exchanger. The transmission position allows heat-exchange communication between the EGHR heat exchanger, the oil-to-water heat exchanger, and the engine. The method also includes monitoring an ambient air temperature and comparing the monitored ambient air temperature to a predetermined cold ambient temperature. If the monitored ambient air temperature is greater than the predetermined cold ambient temperature, the two-way valve is set to the transmission position. | 06-07-2012 |
20140230408 | SYSTEM AND METHOD FOR EXHAUST GAS AFTERTREATMENT - In one embodiment, a method for controlling nitrogen oxides in an exhaust gas received by an exhaust system, the exhaust system including a first selective catalytic reduction device, an exhaust gas heat recovery device and a second selective catalytic reduction device is provided. The method includes flowing the exhaust gas from an internal combustion engine into the first selective catalytic reduction device, receiving the exhaust gas from the first selective catalytic reduction device into the exhaust gas heat recovery device and directing the exhaust gas to a heat exchanger in the exhaust gas heat recovery device based on a temperature of the internal combustion engine proximate moving engine components. The method includes adsorbing nitrogen oxides from the exhaust gas via a nitrogen oxide adsorbing catalyst disposed in the heat exchanger and flowing the exhaust gas from the exhaust gas heat recovery device into the second selective catalytic reduction device. | 08-21-2014 |
20140261254 | COOLANT CONTROL SYSTEMS AND METHODS FOR WARMING ENGINE OIL AND TRANSMISSION FLUID - A coolant control system of a vehicle includes a target pressure module and a thermostat valve control module. The target pressure module determines a target pressure of coolant in a coolant path between a thermostat valve and at least one of an engine oil heat exchanger and a transmission fluid heat exchanger. The thermostat valve control module closes the thermostat valve and blocks coolant flow out of an engine when a temperature of coolant within the engine is less than a predetermined temperature. When the temperature is greater than the predetermined temperature, the thermostat valve control module controls opening of the thermostat valve to the coolant path based on the target pressure. | 09-18-2014 |
