A system for humidification of a fuel cell electric vehicle includes a fuel cell stack for producing electrical energy through an electrochemical reaction of hydrogen and oxygen, a water supply tank for storing water generated during power generation in the fuel cell stack, a first duct for supplying air exhausted from a heating, ventilation, and air conditioning (HVAC) apparatus to a vehicle glass, a second duct for supplying air exhausted from the HVAC apparatus into the vehicle interior, a humidification apparatus for humidifying air supplied through the second duct using water supplied from the water supply tank, and a controller that supplies air to the vehicle glass through the first duct to perform anti-fogging control of the vehicle glass when adjusting an inside humidity of the vehicle using the humidification apparatus.

A vehicle air conditioner installed in a vehicle includes: an evaporator that is provided on a ceiling of the vehicle and causes heat exchange between air in an interior of a passenger compartment and a coolant; a condenser that causes heat exchange between the coolant and outside air; a spray nozzle that sprays water to a portion near the condenser; a water tank that is provided in a lower portion of the vehicle and stores the water to be sprayed; and a drain hose that guides condensed water generated in the evaporator to the water tank. The drain hose is provided through a pillar.

The present invention relates to a vehicle air conditioner and, more specifically, to a vehicle air conditioner which supplies, to a variable heat exchanger, condensate water and air, that have been blown by means of a supply part and passed through an evaporator, so as to enable sub-cooling and overall performance of the variable heat exchanger to be improved during cooling, thereby further increasing cooling performance, and which may use air and condensate water as a heat-absorbing heat source during heating so as to further increase the heat absorption amount of the variable heat exchanger, so that heating performance may be further increased, and thus overall power consumption for air conditioning may be reduced and an increase in heat pump system performance may be promoted.

An air purifying device, system and method for cleaning and infecting a conditioned space or zone. The air purifying system may include a heating, ventilation and air conditioning (HVAC) system with HVAC equipment configured to provide conditioned air to a conditioned space, where the HVAC system also includes a condensate trap configured to collect condensate produced during operation. The air purifying system also including an air purifying device configured to energize the condensate from the condensate trap to generate an aerosol including negative ions, which are combined the conditioned air provided by the HVAC system to the conditioned space.

A mounting structure of a thermal management module for a vehicle, includes: a mounting carrier mounted at a front of a vehicle body and having a receiving space; and a thermal management module mounted in the receiving space; wherein the thermal management module includes: an air conditioner mounted in the receiving space and configured to adjust a temperature of a vehicle interior according to a cooling mode or a heating mode; and a cooling device mounted in the receiving space and configured to heat-exchange with a working fluid using an external air introduced from outside of the cooling device.

Air conditioning units each include an evaporator, a blower fan, a compressor that compresses a coolant, a condenser that causes heat exchange between the coolant and outside air, a coolant pipe that causes the coolant to circulate, and a spray nozzle that sprays water in a mist form to the outside air flowing to the condenser. The evaporator and the blower fan are provided in a ceiling portion of the vehicle, and the condenser and the spray nozzle are provided in a lower portion of the vehicle.

A vehicle air conditioner installed in a vehicle includes a condenser that causes heat exchange between a coolant and outside air, and a spray nozzle that sprays water to a portion near the condenser that are provided in each of a front side accommodation space positioned in a lower front portion of the vehicle and a rear side accommodation space positioned in lower rear portion of the vehicle.

The invention relates to a method for controlling the recovery of water in a motor vehicle, in which method, to recover water in an air-conditioning system (12) of the motor vehicle, air is cooled to a temperature below its dew point, and the water dropping out as a result of the cooling is collected in a water container (13). During water recovery, the air-conditioning system (12) is controlled by means of a water recovery control device (11), wherein, to control the water recovery by means of the water recovery control device (11), the air-conditioning system (12) is adjusted on the basis of at least one parameter value which is detected by a detection unit (10) and transmitted to the water recovery control device (11).

An air conditioner for a vehicle includes a first heat exchanger that exchanges heat between a refrigerant in a refrigeration cycle and a heat medium, a second heat exchanger that exchanges heat between air to be blown into a vehicle interior space and the heat medium, and a casing disposed in the vehicle interior space to form an air passage through which the air flows and to accommodate the second heat exchanger. The first heat exchanger is disposed under the casing, and a partition wall for partitioning an engine room from the vehicle interior space is interposed between the first heat exchanger and the casing.
