This disclosure provides an engineering vehicle and an air conditioning system thereof beneficial to improve comfortability of drivers. The air conditioning system includes: an air conditioner body, including a shell with first and second air outlet; a first air supply pipeline, a first end of the first air supply pipeline being connected to the first air outlet; first air support port(s), arranged at an inner front end of a cab of the engineering vehicle and connected to a second end of the first air supply pipeline; a second air supply pipeline, a first end of the second air supply pipeline being connected to the second air outlet; second air supply port(s), arranged at an inner rear end of the cab and connected to a second end of the second air supply pipeline; and a flow distribution device including a flow dividing portion located in the shell.

A vehicle air conditioner is disclosed. The present invention provides the vehicle air conditioner, which: can directly control the amount of air passing through an evaporator and a heater core since a blower is disposed between the evaporator and the heater core; has front and rear seat discharge units respectively having heater cores, thereby having a simple form, minimizing energy consumption, and independently enabling four or more zones, including front and rear seats, the left and right of the front seats, and the left and right of the rear seats, to be air-conditioned; and can discharge an offensive smell to the outside during initial driving of a vehicle since the air outside a vehicle, flowing in from an air inlet, and indoor air flowing in from an inside air suction port, disposed at the center of the vehicle, are discharged to the outside of the vehicle by means of a second blower, and not by a front seat blower, for discharging the air to the rear seats.

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.

A rotary apparatus includes a motor, a plurality of gears including an output gear, and a housing accommodating the plurality of gears and the motor. The housing includes a first surface portion, a second surface portion facing the first surface portion and spaced apart from the first surface portion, and a sidewall portion provided at an outer peripheral portion of the first surface portion and the second surface portion and supporting the first surface portion and the second surface portion. One of the first surface portion and the second surface portion includes a vibration damping part opposing the output gear.

A first sensor measures temperature at a first evaporator that cools a first zone. A second sensor measures temperature at a second evaporator that cools a second zone. A controller operates a compressor in a normal cooling mode or a single zone cooling mode. In the normal cooling mode, both the first zone and the second zone are cooled with the compressor operated by the controller in response to temperature measurements from one or both of the first sensor and the second sensor. In the single zone cooling mode, only the second zone is cooled with the compressor controlled by the controller in response to temperature measurements from the second sensor and the controller determining that the first evaporator has a low probability of accumulating frozen moisture on surfaces thereof, and in response to determining a high probability of accumulating frozen moisture on surfaces thereof the compressor is not operated.

A configured mode of operation of a wireless sensor node unit can selectively activate a first subset of sensor channels of data and selectively deactivate a second subset of sensor channels of data. The configured mode of operation customizes the sensor functionality in the wireless sensor node unit in support of the delivery of data streams to customers.

A modification of a sensor data management system to enable discrete sensor applications. A sensor data control system enables discrete sensor applications to control the configuration, collection, processing, and distribution of sensor data produced by selected sensors at various monitored locations. The sensor service offered by the sensor data control system can be leveraged by any sensor application having an interest in any part of one or more monitored locations.

The invention relates to a vehicle air conditioner (10), with an evaporator (12) for supplying cold air (14) which can be fed to a vehicle interior (16), an air-mixing region (18) which is connected downstream of the evaporator (12) and can supply mixed air at a predeterminable temperature, a first ventilation duct (20) which is connected to the air-mixing region (18) and can conduct mixed air from the air-mixing region (18) into a front region (22) of the vehicle interior (16), and a second ventilation duct (24) which is connected to the air-mixing region (18) and can conduct mixed air from the air-mixing region (18) into a rear region (26) of the vehicle interior (16), wherein, in addition, a separate cold air duct (28), which can feed cold air (14), which is supplied by the evaporator (12), to the vehicle interior (16) in substantially unmixed form is provided.

An individual air conditioning apparatus for a vehicle includes: a driver's seat air conditioning module and a passenger seat air conditioning module sequentially provided with an evaporation core and a heater core; a first channel that passes through the evaporation core and is connected to an indoor outlet; a second channel that passes through the evaporation core and the heater core and is connected to the indoor outlet; and a temperature control door that opens and closes the first channel and the second channel.

A cooling system for at least one electronic control unit of a motor vehicle, the cooling system comprising a housing for the at least one electronic control unit, the housing comprising an air circulation duct configured to supply air to the at least one electronic control unit, wherein the air circulation duct comprises a first inlet configured to be connected to a vehicular air conditioning device, and a second inlet configured to be connected to inside a driver's cab of the motor vehicle.
