An air conditioner for a vehicle which can block air introduced through a gap between an evaporator and an air-conditioning case and prevent condensate from overflowing toward a temperature adjusting door when condensate exceeding a drainable amount is generated. The air-conditioning case has an air passageway therein. An evaporator is disposed in the air passageway. A drain hole is disposed at a downstream side of the evaporator in an air flow direction to discharge condensate to the outside. A first baffle protrudes upwardly from a bottom surface of the air-conditioning case for preventing air from leaking between the air-conditioning case and the evaporator.

A car having a water box comprising an outer face, an inner face, an air inlet opening, an air outlet opening and a water outlet opening. The inner face forms a water separating space that is connected to the air inlet and outlet openings and the water outlet opening. The water outlet opening discharges water out of the separating space. An air conditioner is connected to the air outlet opening to feed air from the water box into the air conditioner. An air feeding unit sucks the air into the air conditioner via the air inlet opening. The air feeding unit is designed as a suction fan. The water box comprises a wall that comprises fibers forming a non-woven fabric i.e. felt.

The refrigeration system is configured to adjust a temperature inside a vehicle compartment of the transport vehicle, the refrigeration system including an evaporator disposed in the vehicle compartment and the evaporator including evaporator coils (120) through which a refrigerant flows and a housing (110) for accommodating the evaporator coils; wherein the housing is further provided with a heating element (130); and the refrigeration system further includes a control module (140) configured to control the heating element. According to the refrigeration system for a transport vehicle, the control method thereof and the transport vehicle of the present disclosure, by disposing the heating element inside the housing of the evaporator, which is controlled to perform heating and stop heating according to actual situations, ice is prevented from being formed on the inner side of the housing, and condensation water is prevented from being formed on the outer side of the housing, thereby effectively improving the reliability of the preservation of goods.

A water discharge device that collects and drains condensed water generated in an air conditioning device includes: a drainage path along which condensed water is able to be drained in a draining state in which condensed water is expelled; and an opening and closing member that is able to block and open the drainage path. The opening and closing member blocks the drainage path so as to limit movement of air due to dynamic pressure when in a non-draining state other than the draining state. The opening and closing member drains condensed water through the drainage path when in the draining state.

An air-conditioning unit of a motor vehicle may include a fan, an evaporator, and a heat exchanger. The heat exchanger may be arranged downstream of the evaporator. The evaporator and heat exchanger may both be arranged in a housing. The air-conditioning unit may also include a first bypass channel bypassing the evaporator. The first bypass channel may be arranged centrally on a side of the evaporator. A width of the first bypass channel may be smaller than a width of the side of the evaporator on which the first bypass channel is arranged.

Disclosed is a landscaped surface applicable to all types of vehicles, which includes a frame with a settling base that rests on a detachable supporting element or directly on the roof of the vehicle, inside which there are separator partitions and a root development base made of flexible and light hydrophilic material, with a reticular structure that retains a volume of water of between 10 and 30 times the weight thereof, expelling the excess via drainage openings arranged in the lower area of its vertical face of the frame. There is a layer of covering vegetation on the root development base and a mesh secured to a fastening flap in the high part of the frame.

A drain hose includes a hose main body into which a drain pipe is inserted and a circumferential rib formed on an outer peripheral surface of the hose main body to be away from an extremity of the hose main body and extend in a circumferential direction of the hose main body. The drain hose includes an axial rib formed on the outer peripheral surface of the hose main body to be positioned closer to the extremity of the hose main body than the circumferential rib and extend in an axial direction of the hose main body.

A vehicle air conditioning system provides a heat exchanger and a vehicle air conditioning system comprising same, which can simplify the overall structure and can easily perform cooling/heating of air for air conditioning and dehumidification heating by using an integrated heat exchanger which is selectively supplied with low- and high-temperature cooling water by a supply valve to perform heat exchange.

An air supply system for a vehicle includes a first system including a first compressor compressing ambient air, a heat exchanger connected to the first compressor to allow compressed air to flow therethrough, and a first condenser connected to the heat exchanger. The air supply system further includes a second system including a second compressor compressing a refrigerant, a second condenser disposed at a rear end of the second compressor, an expansion valve disposed at a rear end of the second compressor, and an evaporator disposed at a rear end of the expansion valve. The second compressor, the second condenser, the expansion valve, and the evaporator of the second system are sequentially connected by a refrigerant flow line, and a refrigerant pipe disposed in the evaporator of the second system and connected to the refrigerant flow line is connected to a refrigerant pipe for a first condenser.

An air conditioning system has a fan configured for generating an airflow in a predetermined direction. The system includes a heat exchanger assembly configured for being crossed by the airflow for exchanging heat in a controlled manner. An air outlet is located downstream of the heat exchanger assembly and configured for delivering the airflow. The heat exchanger assembly includes an evaporator having a back surface or side facing towards the air outlet and configured for being crossed by the cooled airflow. The system also includes a droplet separator located downstream of and in proximity to the back surface or side. The droplet separator is configured for deviating droplets of water vapor condensed on the back surface or side, so as to prevent the down flow of the droplets of water vapor towards the air outlet.
