Abstract: Various disclosed embodiments include illustrative heating, ventilation, and air conditioning (HVAC) cases, HVAC systems, vehicles, and methods. In an illustrative embodiment, a heating, ventilation, and air conditioning (HVAC) system includes a case, a blower disposed in the case and configured to cause air to flow, a first heat exchanger disposed in the case and configured to heat the air, and an ambient extractor port defined in the case and configured to discharge to an ambient environment exterior to a structure the air provided to the ambient extractor port.

Abstract: Various disclosed embodiments include illustrative heating, ventilation, and air conditioning (HVAC) devices, HVAC systems, vehicles, and methods. An illustrative HVAC system includes a case configured to at least partially recirculate air within the case, a blower disposed in the case and configured to cause air to flow, a first heat exchanger disposed in the case and configured to heat the air, and a second heat exchanger disposed in the case and configured to exchange heat with the air.

Abstract: A vehicle climate control system includes a heating, ventilation, and air conditioning (HVAC) system where condensate from the system is conveyed to a misting device disposed at an air-conditioned outlet in the cabin of the vehicle. The misting device can be arranged at the exit of the air-conditioned outlet such that conditioned air is conveyed by the HVAC ducting and mixes with the mist generated by the misting device at the air-conditioned outlet. The mist may be scented using an injection device that pumps a fragrant fluid into the misting device along with the condensate. Prior to conveying the condensate to the misting device, the condensate may be pumped through bacteria and sediment filter media providing a clean supply of condensate to the misting device. Positioning the misting device at the air-conditioned outlet helps prevent mold or debris from being trapped in the HVAC system or ducting.

Abstract: A thermal management device for use in a vehicular or other thermal management circuit utilizes a pump, one or more valves, and one or more pressure/temperature sensors to route coolant through different desired flow paths and maintain components within the thermal circuit at appropriate temperatures.

Abstract: A thermal management system comprises a coolant system and a separate refrigerant system that are both selectively interconnectable to a chiller. The coolant system includes a radiator and a plurality of fluid lines forming a selectable interconnectable array of coolant loops. This array includes an energy storage system coolant loop and an electrical drive system coolant loop that are separately interconnectable with the radiator and that control the temperature of the energy storage system and the electrical drive system of an electric vehicle. The refrigerant system includes a condenser, an internal heat exchanger, and an array of refrigerant loops that control the temperature of a cabin of the electric vehicle. Together, the coolant system and the refrigerant system provide multiple thermal control modes for components of an electric vehicle.

Abstract: A thermal management system comprises a first coolant loop with a first pump, a second coolant loop with a second pump, and a refrigerant loop. A four-way valve is selectively configurable to maintain the first and second coolant loops separate, or to combine the first and second coolant loops in a single coolant loop operable with one of the first pump and the second pump. The refrigerant loop includes an inside condenser for conditioning air, and a chiller for extracting heat from coolant. The thermal management system is capable of operation in a plurality of modes depending on the thermal state of components heated and cooled by the thermal management system.

Abstract: Embodiments of the present disclosure are directed to using condensation from an evaporator of a cooling system of the vehicle to facilitate thermal management of systems or components of the vehicle. According to one embodiment, a vehicle can comprise a cooling system evaporator and a condensation water collection system disposed in proximity to the cooling system evaporator. The condensation water collection system can be adapted to collect and accumulate condensed water from the cooling system evaporator. The vehicle can further comprise a heat exchange and one or more spray nozzles disposed proximate to the heat exchanger. The spray nozzles can be adapted to dispense a mist of water obtained from the water accumulated by the condensation water collection system onto the heat exchanger.
