A vehicle air conditioner installed in a vehicle includes: a condenser that causes heat exchange between a coolant and outside air; at least one spray nozzle that sprays water to a portion near the condenser; and a water tank that is in communication with the spray nozzle through an output hose, and stores the water to be sprayed. The at least one spray nozzle is disposed at a higher level than the water tank.

The present invention relates to an air conditioner for a vehicle, which can remarkably improve resistance against an air flow in an air passageway, thereby enhancing efficiency. The air conditioner for a vehicle includes: a case having an air inlet, an air outlet, and an air passageway formed therein; a blower unit for blowing air to the air inlet; and a cooling means and a heating means disposed in the air passageway of the case in an air flow direction in order, wherein the air outlet of the case includes a floor outlet and vent outlets, the floor outlet and the vent outlets are arranged below the heating means in a height direction, and the floor outlet is arranged within a range of the width of the heating means.

A reheating process for operating a cooling system having a heat pump function for a motor vehicle. The reheating process includes steps of determining a heat differential value by comparing a heat emission actual value at the heating register to a heat emission target value, and adjusting at least one operating setting of the cooling system, so that the power consumption in the cooling system is increased if the heat differential value is greater than 0 and less than a heat differential threshold value.

The present invention relates to an air conditioner for a vehicle, which can send air-conditioned air toward a rear seat of the vehicle in order to perform air-conditioning of a front seat of the vehicle and air-conditioning of a rear seat. The air conditioner includes an air passageway formed in an air-conditioning case, wherein the air passageway includes: a rear seat cold air passageway which is a passageway that the air passed through the heat exchanger for cooling bypasses the heat exchanger for heating and flows toward a rear seat of the vehicle; and a warm air passageway which is a passageway that the air passed through the heat exchanger for cooling passes through the heat exchanger for heating and flows toward a front seat or the rear seat of the vehicle. The air conditioner includes a rear seat temperature adjusting door for controlling an amount of air flowing from the warm air passageway to the rear seat air outlet and an amount of air flowing from the rear seat cold air passageway to the rear seat air outlet.

A work machine, such as a skid steer loader or a compact track loader, includes an air intake assembly for a heating, ventilation, and air conditioning (HVAC) unit. A conduit integrated into a structure supporting a roof over an operator cab accepts air and water from the atmosphere through an air inlet proximate the roof. A debris outlet downstream in the conduit allows gravity to return the water to the environment. Between the air inlet and the debris outlet, an orifice in the conduit connects to an air duct through which the air may be diverted by suction from the HVAC unit. An air filter at the end of the air duct removes remaining particulates from the air prior to conditioning by the HVAC unit. Sizing the cross-sectional areas of the air path to exceed a cross-sectional area of an inlet to the air filter and providing a substantially straight air path avoids resistance to air flow, resulting in efficient intake of cleaner air.

A thermal control system for a vehicle includes a first heat exchanger configured to thermally condition first intake airflow received at a first end of a vehicle cabin, a second heat exchanger configured to thermally condition second intake airflow received at a second end the vehicle cabin, a thermal loop circulating a working fluid between the first heat exchanger and the second heat exchanger, and a flow control system configured to cause the working fluid to circulate in opposite flow directions through the thermal loop for the first and second heat exchangers to operate in heating and cooling modes.

An air conditioning apparatus for a vehicle includes an air conditioner unit disposed in an air conditioning room of a vehicle and configured in such a manner that ambient air, introduced into the air conditioning room from an outside of the vehicle, is suctioned and blown to an interior of the vehicle by a blower; a damper installed in an opening on an introduction side of the air conditioner unit to selectively allow introduction of one of indoor air flowing from the interior and ambient air; and an internal exhaust grill installed in the interior to fluidly communicate with a space defined by the air conditioner unit and an internal side surface of the air conditioning room, wherein the indoor air in the interior may be discharged to an outside of the vehicle through the internal exhaust grill and the air conditioning room.

A climate control system for a vehicle includes a front-end or first heat exchanger configured to thermally condition airflow from an environment external to a vehicle cabin, a rear-end or second heat exchanger configured to thermally condition airflow from the vehicle cabin, a recirculation path configured to return airflow from the second heat exchanger to the vehicle cabin, and an extraction path configured to vent airflow from the second heat exchanger to the environment external to the vehicle cabin. Various operational modes of the climate control system direct airflow to either the recirculation path or the extraction path.

A rear air conditioner for a vehicle including a discharge module mounted at an air outflow port of an air-conditioning case and having a discharge case and a rotary mode door; two face vents formed at both side walls of the discharge case; a floor vent formed at the center of the discharge case; and an air mixing zone formed inside the rotary mode door, thereby reducing the size of the air conditioner because a plurality of the vents are intensively arranged in the discharge case, enhancing installability due to the modulated components, reducing a temperature difference of the air discharged to the left and right sides inside the vehicle due to an improved mixability. The inside of the rotary mode door can be utilized as the air mixing zone. The degrees of opening of the face vents and the floor vent are controlled by the single mode door.

A rear passenger seat air ventilation system for an electric vehicle includes a rigid tunnel positioned within a passenger compartment of the electric vehicle. The rigid tunnel covers a portion of a battery assembly that extends above a floor structure of the electric vehicle such that the passenger compartment is sealed from the battery assembly. The rigid tunnel defines a forward opening and a rear opening connected by a conduit extending along at least a portion of a length of the rigid tunnel. The conduit is disposed within an interior of the rigid tunnel. A center console is positioned above at least a portion of the rigid tunnel. An air supply system interfaces with the forward opening and to deliver air to the conduit. At least one air vent receives air from the conduit and deliver the air to a rear seating area of the passenger compartment.
