An air changeover system for a metal hydride heat pump is disclosed. The system includes metal hydride reactor modules aligned and separated by a partition; a shell containing the reactor modules, the shell is compartmentalized to define separate insulated chambers for each of the reactor modules; and a bearing assembly supporting the modules at a location about the partition, wherein the bearing assembly rotates said modules about an axis during the absorption and the desorption mode. The system reduces thermal inertia and pressure drop in the heat transfer medium while flowing through the heat pump, to enhance the performance and conserve energy.

Air conditioning system for multi-zone air conditioning of a motor vehicle interior comprising a casing with a mixing chamber and several zone outlets outgoing from mixing chamber, in which an evaporator and at least one heat exchanger are disposed such that main air flow from evaporator through at least one heat exchanger into zone outlets is linear and at least two bypass channels, each comprising a louver, in order to circumvent at least one heat exchanger connect a region downstream of evaporator and a region downstream of at least one heat exchanger, wherein the first bypass channel, as a mixing bypass channel, opens out into mixing chamber and the second bypass channel, as a stratification bypass channel, opens out into a zone outlet.

The present invention relates to an air conditioner for a vehicle, which is configured in a semi-center mounting type having a separable evaporator unit to be assembled to a blower unit and a heater unit, such that the blower unit and the heater unit can be in common use even though the evaporator unit is manufactured according to the size of an evaporator, thereby reducing development costs and development time.

The present invention relates to an air conditioner for a vehicle, and more particularly, to an air conditioner for a vehicle in which heating performance may be improved using an auxiliary heating heat exchanger and stability of a passenger may be improved by providing the auxiliary heating heat exchanger in an engine room.

Disclosed herein is a heat pump system for a vehicle which includes an evaporator mounted on a cold air passageway inside an air-conditioning case, a condenser mounted on a warm air passageway, a first blower mounted at an inlet side of the cold air passageway of the air-conditioning case, a second blower mounted at an inlet side of the warm air passageway and an intake duct mounted between the first blower and the second blower to supply indoor air and outdoor air to the first blower and the second blower respectively, thereby maximizing space efficiency because using just one intake duct for the two blowers, and reducing the size and manufacturing costs of the heat pump system.

The present invention relates to an air conditioner for a vehicle, which includes a cold air passageway and a warm air passageway, and two blowers disposed in the air passageways, thereby rapidly ventilating the interior of the vehicle using the two blowers.

A method for digitally controlling a heating arrangement may include receiving a temperature value with a control device, the temperature value reflecting a current outside temperature. The method may also include determining via the control device, based on the received temperature value, a limit output of the heating arrangement that is smaller than a maximum output of the heating arrangement. The method may further include dividing the determined limit output into a plurality of output stages via the control device, a number of the plurality of output stages corresponding to a digital resolution of the control device. The method may additionally include controlling the heating arrangement between a minimum output and the limit output to one of the plurality of output stages.

An air-conditioning system for a vehicle is provided. The system includes a heating blower and a cooling blower that are disposed on opposite sides with an adjustment space being interposed there between. A first duct and a second duct transfer outside air or inside air and extend in the axial direction of the heating blower and the cooling blower. An inlet door unit is disposed in the adjustment space and adjusts the air introduced from the first duct or the second duct to be selectively supplied to the heating blower or the cooling blower. A condenser and an evaporation core are respectively disposed in the radial directions of the heating blower and the cooling blower and are connected via a refrigerant line. An outlet door unit regulates the air to be selectively discharged to the indoor space or the outdoor space.

A vehicle climate control unit with an evaporator, a heating heat exchanger as well as a blower, characterized in that, in the direction of the air flow, are disposed, upstream of the blower on the suction side, the evaporator and the heating heat exchanger, and that an additional heating heat exchanger is disposed downstream of the blower on the pressure side.

A heating, ventilation, and air conditioning (HVAC) system for a cargo vehicle includes an evaporator, a first door, a condenser, a second door, a freezing room, a refrigerating room, a warming room, and a controller, wherein the controller is configured to control an amount of opening of each of the first internal air and external air door, the second internal air and external air door, the first door, and the second door and an amount of driving of each of the evaporator and the condenser in response to an outside air condition of a vehicle, controlling temperature of each of the freezing room, the refrigerating room, and the warming room.
