An in-vehicle computer includes a computer casing, an electronic component, a fan, and an air duct. The electronic component and the fan are disposed inside the computer casing. An air inlet of the air duct is located outside the computer casing, and an air outlet thereof is toward or connected to the fan. The fan can generate an airflow for dissipating heat from the electronic component. Therein, the computer casing, the fan, and the air duct therefore form a heat dissipating system. A vehicle includes a vehicle cage and the in-vehicle computer. The in-vehicle computer is disposed inside the vehicle cage. The air inlet of the air duct communicates with the interior space of the vehicle cage, so that when the air conditioner of the vehicle is turned on, the fan can draw the cold air from the cockpit space for enhancing the heat dissipation efficiency.

Secondary loop air conditioning and heat pump systems include a reservoir with a capsule holding a phase change material.

An inlet subassembly for a heating, ventilation, and air conditioning (HVAC) system. The inlet subassembly includes a fresh air inlet and a fresh air door movable to control fresh airflow through the fresh air inlet. The inlet subassembly further includes a recirculation air inlet and a partition defining a first airflow channel and a second airflow channel extending from the recirculation air inlet. A recirculation air door is adjacent to the recirculation air inlet and is movable to a closed position restricting recirculated airflow into both the first airflow channel and the second airflow channel, an open position permitting recirculated airflow into both the first airflow channel and the second airflow channel, and a two-layer position in which the recirculation air door restricts recirculated airflow into the first airflow channel and permits recirculated airflow into the second airflow channel.

A proximity air conditioner is capable of performing energy-saving and efficient air-conditioning. A proximity air-conditioning unit for vehicles includes: a housing; a temperature adjustment unit including a temperature adjuster and a blower; and ducts, wherein upper ends of blowout ports of ducts are located above seat surfaces of seats, end portions in a long-side direction of the blowout ports are located on a front side with respect to other end portions thereof in a front-back direction of the seats, and the temperature adjustment unit is disposed between both end portions in the long-side direction of each of the blowout ports.

Features for a vapor compression system configured to cool and/or cat (i.e. thermally condition) two or more distinct climate controlled vehicle interior components via a common thermal bus are disclosed. Some embodiments employ a single compressor. Some embodiments employ multiple compressors and/or thermal buses, each servicing components located within respective interior thermal zones of a vehicle, for example a front row seat zone, second and/or third row seat zones, and/or an overhead zone and/or a trunk zone.

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.

The present invention relates to refrigerated trucks, more particularly to a front-mounted external cold air intake system for a large refrigerated truck, including a refrigerated compartment, an indoor chiller unit, an outdoor chiller unit, a front-mounted air duct, air outlets, horizontal louvers, folding elbows, windshields, blade control knobs, filters, covers, wind deflectors and blades. In the front-mounted cold air intake system, the front-mounted air duct introduces outdoor cold air into the refrigerated compartment, and transmits and distributes the cold air through the air outlets. Moreover, the air window structures formed by the horizontal shutters, the folding elbows and the windshields are used for discharging air, so as to stabilize the pressure in the refrigerated compartment. The system of the present invention uses outdoor cold air to effectively cool the compartment allowing for energy saving of the refrigerated truck.

Disclosed is an HVAC system configured to reduce noise. The HVAC system includes a door having a first and second end. The door includes an elastomer along the first end and a rotatable member adjacent the second end. The elastomer includes a door touch area. The case defines an internal case portion, external case portion, and a case opening fluidly connecting the internal and external case portion. The case is configured to receive the rotatable member of the door such that the door is rotatable about an axis between a first position, where the door covers the case opening, and a second position, where the door does not cover the case opening. The case includes a case touch area with a graining. The door touch area and the case touch area are substantially parallel and in contact along a surface contact area when the door is in the first position.

A vehicle air conditioning device having a split housing structure includes: a front housing disposed in a compartment of a vehicle; a heat exchanger disposed in the front housing, a rear housing disposed in an engine room or a motor room of the vehicle; a firewall through which the front housing is connected with the rear housing; an inlet; a blower disposed in the rear housing; an evaporator configured to cool air or to chill air; upper and lower mixing doors disposed in an up-and-down direction downstream of the evaporator; a first plate member disposed between the upper and lower mixing doors; a second plate member disposed downstream of the heat exchanger; an upper outlet; and a lower outlet. The first plate member divides the airflow from the evaporator, and the upper and lower mixing doors each guides the airflow to selectively flow through the heat exchanger.

A ventilation device may include a housing, a fluid channel system, a heat exchanger, and a slider arrangement. The slider arrangement may include at least one first slider and at least one second slider arranged within the fluid channel system upstream of the heat exchanger and downstream of the heat exchanger respectively. The first and second slider may be guidable transversely with respect to at least one fluid flow. The first and second slider may each be actuatable. At least one of a volume flow and a mass flow of at least one fluid flow may be at least one of controllable and regulatable via actuation of the first slider. At least one of a predetermined fluid temperature and a predeterminable fluid temperature of a mixed fluid may be settable and at least two fluids may be mixable via actuation of the second slider.
