Abstract: This invention relates to a hybrid electric vehicle component coolant control system and method. The coolant system has an electric pump to move coolant through a closed system including engine and motor components. Such components to be cooled can include any electric motors, power electronics, engine, and transmission. The preferred embodiment controls coolant flow to the vehicle engine and motor in a single closed loop. Vehicle components have temperature sensors that send temperature signals to an electric coolant pump duty cycle control strategy. The control strategy makes a determination of a duty cycle of the electric coolant pump as a function of the temperatures of vehicle components and orders the duty cycle of the electric pump. In the preferred configuration, engine temperature sensors can acquire either engine coolant temperature or engine cylinder head temperature.

Abstract: In a vehicle air conditioner, an air conditioning case has a front air passage and a rear air passage through which air is blown to a front seat side and a rear seat side in a passenger compartment, respectively. The air conditioner includes an air-blowing amount determination unit for determining an air-blowing amount of a blower, and a correction unit for increasing the air-blowing amount determined by the determination unit when the rear air passage is opened. The correction unit increases an increase amount of the air-blowing amount to be larger in a face mode, than that in a bi-level mode.

Abstract: A compact vehicle heating system and method is provided which includes mechanisms to selectively shut down heating systems. For example, when domestic hot water is required, space heating and engine preheating systems can be shut down in order to provide priority heating to the domestic hot water. When the demand for domestic hot water is lower, the space heating and engine preheat systems can be reactivated.

The frame extends through an exterior wall and into the passenger compartment of the vehicle. Removal of the cover plate permits access to the components of the climate control unit for service or replacement. In the preferred embodiment, the frame includes a casing having a top wall, a floor and three side walls, and the climate control unit is a heater having a filter, heat exchanger, and blower fan. Liquid coolant, warmed by the internal combustion engine of the bus, is circulated from the engine to the heat exchanger.

Abstract: A vehicle includes a fuel cell that generates electricity and water, which fuel cell includes a first end, a second end electrically coupled to the first end, and a water outlet. The water outlet of the fuel cell is connected to at least one of a washing system, a cooling system, a humidification system, and combinations thereof. In addition, a method is described for utilizing water produced by a fuel cell that includes generating water from the fuel cell, and conveying a first portion of the generated water to a component of a vehicle, which component, upon actuation, transfers a liquid comprising a portion of the first portion from the component to a point distal therefrom.

Abstract: In a vehicle air conditioner where air blown into a passenger compartment is heated in a heater core using cooling water for cooling a fuel cell system as a heating source, a flow amount of cooling water flowing into the heat core is controlled by a control valve based on a surplus heat quantity of the fuel cell system and a necessary heat quantity of the passenger compartment. Further, when the surplus heat quantity of the fuel cell system is smaller than the necessary heat quantity, an insufficient heat quantity is supplemented by a supplementary heater.

Abstract: In a vehicle air conditioner, an air conditioning case has a center face opening through which air is blown toward a center upper side of a passenger compartment in a vehicle right-left direction, a side face opening through which air is blown toward a side upper side of the passenger compartment, and a defroster opening through which air is blown toward a front windshield of the vehicle. The side face opening is provided between the center face opening and the defroster opening in an arrangement direction of the center face opening and the defroster opening within a width dimension of the center face opening in a direction perpendicular to the arrangement direction. Thus, a dimension of the air conditioning case in the direction perpendicular to the arrangement direction becomes smaller, while operation force of a door for opening and closing the center face opening is reduced.

Abstract: A mobile heating system for providing hot liquids is provided. The system includes a trailer mounted liquid boiler, an exit manifold for distribution through hoses, a return system communicating with a return manifold in communication with a reservoir for storing heated liquid and a bypass valved shunt such that by providing incremental heat through the liquid boiler back to the reservoir via the bypass valved shunt and then back to the boiler through the exit manifold and back to the reservoir by means of the return manifold, sufficient energy is maintained to allow atmospheric 205+ degree liquid to be circulated within the system. In one aspect of the system, by means of contact with the hot hoses, a substance is used for thawing ground, heat, melting snow and ice, curing cement, and the like. In another aspect, the liquid is water used to provide for example, hygienic liquid or hot water for field showers.

Abstract: In a radiator assembly of a water cooled engine driven vehicle, heating is performed by a compartment heat exchanger. As long as the temperature of the cooling water is low, it does not suffice to sufficiently heat by compartment heat exchanger shortly after engine start and an auxiliary heating equipment is used. The auxiliary heating equipment includes a heat exchanger at the heating side, a heat exchanger at the endothermic side and a Peltier element. The Peltier element leads to high energy efficiency because it provides a quantity of heat which is more than the quantity of energy charged into the Peltier element, since it transfers Joule heat generated by the charge energy to the heat exchanger and further transfers a quantity of heat to heat exchanger as absorbed in a heat exchanger at the endothermic side from an endothermic surface of the Peltier element by a Peltier effect to the exothermic side.

Abstract: A particular device is provided for heating and/or air conditioning a vehicle interior. Housings for air conditioners of motor vehicles, typically, are relatively cumbersome to manufacture because of the need to install control flaps in front of and behind the heater. Sealing of the heater in its installation housing is also difficult. It is proposed, therefore, to make the housing for receiving the heater in two parts and to provide a plug-in part for the heater as well as a frame that can be snapped onto the plug-in part as a closure. Both the plug-in part and the frame are provided with an integral control flap arrangement.
