摘要:
A smart HVAC system adapted for selectively regulating fluid flow into a space generally includes an HVAC system including at least one active vent, a preferably variable blower fluidly coupled thereto, and at least one sensor associated with each vent, wherein the sensor is operable to cause the associated vent to shift between opened and closed conditions, and/or preferably the blower output to change, when an occupant is autonomously detected within at least a portion of the space.

A vehicle-integrated water harvesting system is provided that enables water-vapor or condensation in a vehicle to be captured, and made available onboard the vehicle for drinking or other uses. The system includes a water emitting component and may include a purification system operatively connected to the water emitting component. The purification system at least partially purifies the water and then sends the purified water to a storage reservoir or directly to a dispenser or outlet.

A secondary loop air conditioning system for a vehicle that includes a condenser and an integrated assembly is disclosed. The condenser has a first condenser header spaced from a second condenser header, a condenser core extending between the first and second condenser headers, and a refrigerant inlet operatively engaging the first condenser header. The integrated assembly includes a chiller mounted to the first condenser header and having a liquid inlet and a liquid outlet configured to be in fluid communication with a secondary loop of the air conditioning system, and an expansion device in fluid communication with the condenser and mounted adjacent to the chiller for directing refrigerant into the chiller, and a refrigerant outlet. Also, a receiver/dryer area may be located in one of the condenser and the integrated assembly.

An accessory load control system for a vehicle, includes an actuator control module, a period estimation module, and a load control module. The actuator control module operates an internal combustion engine of the vehicle in a high-efficiency (HE) mode. The period estimation module estimates a period between a current time and a future time when an actual load on a crankshaft of the engine will reach a maximum engine load associated with the HE mode. The load control module selectively decreases engine loads applied by vehicle accessories, respectively, based on the period.

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.

An exhaust heat recovery heat exchanger assembly for use along a main exhaust flow path of an exhaust system for an engine, and a method of operation, is disclosed. The exhaust heat recovery heat exchanger includes a sealed vacuum chamber, including a hydride pellet mounted in the chamber, and electrical leads extending from the hydride pellet. An exhaust chamber along the main exhaust flow path is located along an inner wall of the vacuum chamber. A housing surrounds the vacuum chamber and defines a heat receiving medium chamber. A heat receiving medium flows through the heat receiving medium chamber and absorbs heat from the exhaust flowing through the exhaust chamber when an electric current is applied to the hydride pellet.
摘要:
A method and system for removing oil accumulation from refrigerant lines of a vehicle HVAC system having multiple refrigerant loops each having an evaporator is disclosed. The method for operating the system may comprise the steps of: monitoring a flow rate through at least one of the refrigerant loops; determining if the flow rate through any of the at least one refrigerant loops being monitored is below a predetermined flow rate for greater than a predetermined time limit; monitoring for an indication of imminent vehicle operation; and if the indication of imminent vehicle operation is detected and the flow rate through any of the at least one refrigerant loops being monitored is below the predetermined flow rate for greater than the predetermined time limit, opening a valve to allow for maximum flow through the at least one refrigerant loop.
摘要:
The integrated automotive HVAC/PTC system of the present invention includes a bi-fluidic heat exchanger between an air conditioning subsystem and a heating subsystem which enables heat extracted during dehumidification of the ventilation air to be transferred into dehumidified ventilation air. The HVAC/PTC system includes reconfigurable coolant loops and reconfigurable refrigerant loops, some of which act in concert and some of which may be isolated. Power train components, including the power supply, may be grouped by heat transfer requirements and may be cooled or heated as needed. Power train cooling is accomplished with coolant in the heating subsystem chilled by the air conditioning system.

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 includes an HVAC system having an HVAC duct, a blower for directing a flow of air through the HVAC duct, an evaporator located within the HVAC duct, and a heater core. The heater core has a coolant inlet outlet and is located downstream of the evaporator in the HVAC duct. The method includes the steps of cooling a refrigerant; inducing a flow of the cooled refrigerant through the evaporator; blocking a flow of coolant through the coolant inlet and outlet to trap coolant in the heater core; activating the blower to move air through the evaporator and heater core; turning off the vehicle engine; measuring a duct outlet temperature; and starting the engine when the measured duct outlet temperature is above a predetermined temperature.
