An air conditioner energy-saving inflatable device is adapted to be disposed in a vehicle body. The air conditioner energy-saving inflatable device includes an air pump, an air bag, a circuit board and a sensor. The air bag is connected to the air pump and adapted to be disposed beside an area in the vehicle body. The circuit board is electrically connected to the air pump and includes a controller. When an air-conditioning system of the vehicle body is activated, the sensor is adapted to sense whether the area is vacant. When the sensor senses that the area is vacant, the controller instructs the air pump to inflate the air bag, so that the air bag fills at least a portion of the area. When the air-conditioning system of the vehicle body stops running, the air bag is deflated. A vehicle is also provided.

The present embodiments relate to an HVAC system which is externally mounted on a vertical surface of an RV, truck or bus. The desire is to eliminate, or at least substantially reduce, a potential leakage path wherein water may sit on an upper surface of a vehicle and due to seal degradation over long periods of time, may find a pathway in through the roof of the vehicle and to an interior thereof. By positioning the HVAC on a vertical surface, gravity works to move water downward and away from the HVAC system rather than allowing it to stagnate in an area around potential apertures through the outer skin or outer surface of the vehicle.

A vehicle cabin air conditioning system includes a cabin indoor air conditioner and an individual air conditioner configured to condition air in a target space inside a cabin. The individual air conditioner includes a blower, a heat generator, a supply port, and an exhaust port. The supply port supplies one of a cold air cooled with the heat generator and a warm air heated with the heat generator to the target space. The exhaust port provides the other of the cold air and the warm air to outside of the target space. The cabin indoor air conditioner includes a cabin blower, a temperature control unit, and a suction port through which air is sucked for the temperature control unit. An air flow path is provided to guide air sent from the exhaust port of the individual air conditioner to the suction port of the cabin indoor air conditioner.

A temperature control system includes a heater core utilizing heat of a heat medium; an engine heat exchanger utilizing exhaust heat of an engine to heat the heat medium; a condenser utilizing heat other than the exhaust heat to heat the heat medium; a heat circuit having the heater core and condenser; a communication flow path making the engine heat exchanger communicate with the heat circuit; and a connection state switching mechanism switching a flow state of the heat medium, between a first state and a second state. In the first state, the heat medium flows through the heat circuit, while flowing through the heater core, and in the second state, the heat medium flows through the heat circuit without flowing through the heater core. The heat circuit is arranged at a front of a passenger compartment, and the engine heat exchanger is arranged at a rear of the compartment.

An air-handling system includes an evaporator core and a downstream arranged heater core disposed in an air-handling casing. A primary flow path is formed within the air-handling casing and leads to a primary zone of a passenger compartment. The primary flow path is divided into a primary cool air pathway bypassing the heater core and a primary warm air pathway passing through the heater core. A secondary flow path is formed within the air-handling casing and leads to a secondary zone of the passenger compartment. The secondary flow path includes a secondary cool air pathway branching from the primary flow path downstream of the evaporator core and a secondary warm air pathway branching from the primary flow path downstream of the heater core. The secondary cool air pathway bypasses the heater core and the secondary warm air pathway passes through the heater core.

Described herein is air distributing device for an air conditioning unit of a motor vehicle, the device including: a housing defining an air intake chamber, on the housing there being formed an air inlet, a central air outlet, and two side air outlets. The device also includes a drum flap mounted rotatably about an axis (z) orthogonal to a direction that goes from the air inlet to the central air outlet. The flap is movable between a first position, wherein the air inlet is closed by the flap; a second position, wherein the two side air outlets are closed by the flap and an air flow between the air inlet and the central air outlet is allowed; and a third position, wherein the central air outlet is closed by the flap and an air flow between the air inlet and the side air outlets is allowed.

A dual zone auxiliary climate control system for a vehicle includes an evaporator, a heater core having a first zone and a second zone, a first zone mode door downstream from the first zone of the heater core, a second zone mode door downstream from the second zone of the heater core and a blower. The blower forces air through the evaporator and the heater core toward the first zone mode door and the second zone mode door. A method of providing a dual zone auxiliary climate control system is also disclosed.

The present invention provides a construction machine, which includes a cabin in which a driver is seated, the construction machine including a ventilated seat having fans, an air conditioning device configured to adjust an internal temperature of the cabin, and ducts extending from the air conditioning device and configured to guide an air flow, in which the ducts branches to include a first duct extending toward an upper side of the cabin, and a second duct extending toward a rear side of the ventilated seat. Therefore, it is possible to improve a cooling effect that the driver actually feels.
