A secondary loop HVAC system including an evaporator, a condenser, an expansion valve, and a compressor. A refrigerant loop is in fluid communication with each of the evaporator, the condenser, and the expansion valve. An HVAC case includes a first heat exchanger and a second heat exchanger. A first coolant loop is in fluid communication with the first heat exchanger, the second heat exchanger, and either the evaporator or the condenser. A valve system is configured to control flow of the coolant through the first coolant loop. In a maximum hot heating mode, the valve system is configured to direct the coolant through the condenser, the first heat exchanger, and the second heat exchanger. In a maximum cold cooling mode, the valve system is configured to direct the coolant through the evaporator, the first heat exchanger, and the second heat exchanger.

Recreational vehicles are provided with a tapered duct connector and/or a conditioned air receiving sleeve that is positioned in an infra-ceiling space of the vehicle. The tapered duct connector comprises a connector inlet coupled to a conditioned air passage on a wall of the conditioned air receiving sleeve, and a connector outlet coupled to the supply duct, to fluidly couple the sleeve to the supply duct. The tapered duct connector comprises a transitional duct height that increases from the connector outlet to the connector inlet. The conditioned air passage of the conditioned air receiving sleeve, the tapered duct connector, and the supply duct is contained such that air can pass from the conditioned air opening of the conditioned air receiving sleeve, through the conditioned air receiving sleeve, and into the supply duct without contacting structural components in the infra-ceiling space of the recreational vehicle.

A mounting structure for a compressor assembly of an auxiliary air conditioning system for a vehicle includes a mounting plate that includes a first surface, a second surface, a first plurality of apertures, and a second plurality of apertures. The mounting structure also includes a plurality of mounts disposed at the first surface, the plurality of mounts including a mount attached to the mounting plate via fasteners extending through the first plurality of apertures. The mounting structure also includes a mounting panel of a compressor unit of the auxiliary air conditioning system. The mounting panel includes a main portion having mounting apertures overlapping the plurality of mounts. Fasteners are disposed at the mounting apertures to attach the mounting panel to the mounting plate via the plurality of mounts.

A pressure vent valve for ventilation of the interior of a motor vehicle, with a frame with at least one sealing surface and with at least one flexible valve flap mounted on the frame. In an idle position, the valve flap assembly abuts the sealing surface to prevent airflow through the pressure vent valve. When a sufficient pressure occurs, the valve flap assembly assumes an open position lifted from the sealing surface to allow airflow through the pressure vent valve. The pressure vent valve further includes an installation indicator formed in or on the frame to ensure alignment during installation.

Proposed is an air conditioning assembly of a vehicle seat. The air conditioning assembly includes a housing provided in a vehicle seat, in which air flows in an internal space of the housing and the air is discharged to a seating surface of the seat, and an air cleaner provided in the internal space of the housing and configured to selectively sterilize or deodorize the air flowing in the internal space of the housing by rotating according to an air conditioning mode.

A ventilation seat of a vehicle is proposed. The ventilation seat includes a ventilation duct assembly mounted to a seat of the vehicle and configured to suck indoor air and to discharge air toward a vehicle room or a surface of the seat, an air cleaning assembly arranged in an air flow path of the ventilation duct assembly and configured to clean air passing through the air flow path in operation thereof, and a controller configured to operate the ventilation duct assembly in operation of an air cleaning mode of the vehicle to generate an air flow flowing through the seat, and configured to operate the air cleaning assembly to allow the air flow of the ventilation duct assembly to clean air in the vehicle.

A water cooling apparatus may include a first cooling tube including a first main body having a first internal space in which cooling water is provided, and a first connection pipe connected to the first main body, wherein the cooling water is discharged from the first internal space through the first connection pipe, a second cooling tube including a second connection pipe into which the first cooling tube is inserted so that the cooling water is provided from the first connection pipe to the second connection pipe, and a second main body connected to the second connection pipe, wherein the second main body includes a second internal space in which the cooling water drawn from the second connection pipe is provided, and a watertight gasket disposed on the first connection pipe, wherein the first main body and the second main body is spaced from each other with a predetermined distance.

A method for servicing a heater core installed in a heating, ventilation, and air-conditioning (HVAC) assembly for a motor vehicle includes removing a sealing attachment from an interfacing connection interfacing with the heater core. The method includes sliding the heater core in a direction of insertion. The method includes disconnecting, from the heater core, the interfacing connection. The method includes removing the heater core in a direction of extraction, the direction of extraction being orthogonal to the direction of insertion.

A heating, ventilation, and air conditioning (HVAC) system for a vehicle may include a housing, a first heat exchanger, a first door, and a second heat exchanger. The housing may include a first inlet branch, a second inlet branch, and an outlet branch. The first door may be adjacent the first heat exchanger and may move from a first position preventing flow to the first heat exchanger to a second position permitting flow to the first heat exchanger. The second heat exchanger may be positioned downstream of the first heat exchanger.

The present invention relates to an air conditioner for a vehicle, which takes up less installation space due to its compact-sized structure and effectively performs cooling and heating with a simple structure. The air conditioner for a vehicle includes: a case (10) having an air inflow port and an air outflow port; a blower for introducing air into the air inflow port to send the air into the case (10); a compressor (30) for compressing refrigerant; a heat exchanger for exchanging heat between refrigerant and air; and an expansion means for throttling the refrigerant, wherein the blower, the compressor (30), and the heat exchange are arranged inside the case (10) side by side to be formed in a flat type.
