The invention relates to an air intake housing (21), in particular for a heating, ventilation and/or air conditioning device, comprising: —at least two distinct air inlets (24, 26), and —air guiding members (27, 28, 30) configured to direct at least one air flow that is intended to be admitted into the air intake housing (21). According to the invention, the air guiding members comprise at least three flaps (27, 28, 30), one of these being a central flap (27) and two lateral flaps (28, 30) arranged one on each side of the central flap (27), said flaps (27, 28, 30) being positioned between the said two distinct air inlets (24, 26) of the air intake housing (21) so as to be able to move about a single axis of pivoting (33). The invention also relates to a suction blower (1) comprising such an air intake housing (21) and to a corresponding heating, ventilation and/or air conditioning device.

This vehicle cooling device includes a duct communicating with a heating element disposed in a vehicle, an opening provided in the duct, positioned below a seat surface part of a seat disposed above a floor panel, and opening to a passenger compartment, and a fan supplying air suctioned into the duct from the opening to the heating element, in which the opening is positioned on a vehicle-body rear side with respect to a seat fixing part on a vehicle-body front side among seat fixing parts for fixing the seat to the floor panel in a state in which it is disposed on a vehicle-body rear side of a front end of the seat surface part.

A heating, ventilation, and air condition (HVAC) unit including a casing and a door. The casing includes a body portion and a lip portion extending from the body portion. The body portion defines a first inlet opening and a second inlet opening. The door is pivotable between a first position in which ambient air is able to flow through the second inlet opening and air within an occupant cabin is restricted from flowing through the first inlet opening, and a second position in which ambient air is restricted from flowing through the second inlet opening and air within the occupant cabin is able to flow through the first inlet opening. A distance from an outward most location where the door and the lip portion contact each other to an edge of the lip portion that is further outwardly of the outward most location is between 0.1 millimeters and 5 millimeters.

The invention relates to an air-conditioning device (1) for a motor vehicle, comprising an element for circulating air towards an evaporator (4), characterised in that the device (1) also comprises a bypass circuit (9) allowing air circulation between a zone located upstream of the evaporator (4) and a zone located downstream of the evaporator (4), the air bypass circuit (9) being arranged above the evaporator (4).

The present invention relates to an electrification apparatus for electric dust collection and an air conditioner for a vehicle comprising the same. According to the teachings of the present invention, there is provided an electrification apparatus for electric dust collection including: a frame, conductive microfiber and conductive. The frame includes a main body frame in which the conductive plate is installed and an installation frame in which a fixing groove in which the conductive microfiber is installed is formed. At this time, the electrification apparatus for electric dust collection further includes a rubber which is coupled with the conductive microfiber and is inserted into the fixing groove.

A drainage system for draining water from an air intake and from an air distribution housing of an air conditioning system into the environment. The drainage system including a drainage opening or the drainage of water into the environment, wherein the drainage opening is formed on a lower shell of the air distribution housing and is divided into a drainage area for water from the air intake housing on the one hand, and a drainage area for water from the air distribution housing on the other hand, and wherein the drainage area for water from the air intake housing is formed by the terminus of a separate duct for the drainage of water from the air intake. In this way, the reciprocal effect between the different pressure levels is avoided or reduced to the extent possible.

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.

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.

A ventilating tube may include a body through which air is flowable in an air flow direction and a sound attenuating mechanism for attenuating airborne noise. The sound attenuating mechanism may be a wavelength resonator, which may include at least one resonance chamber. On one side, the at least one resonance chamber may have an opening which opens the at least one resonance chamber into the body transversely to the air flow direction.
