A compressor module, as a component of a refrigerant cycle device, is attached to a casing that houses a refrigeration cycle device. The compressor module includes a compressor that compresses refrigerant, a supporting member that supports the compressor, a vibration-reducing rubber body that is attached to the supporting member, ancillary equipment that is added to the compressor, a base supporting the supporting member via the vibration-reducing rubber body and supporting the ancillary equipment with a portion of the base other than the portion supporting the supporting member.

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.

A HVAC system for a motor vehicle having a housing, wherein the housing has an air inlet for admitting air and a cold air path in which cold air flows is provided in the housing and a warm air path in which warm air flows is provided in the housing, wherein the warm air path and the cold air path open into a mixing chamber, wherein a mixing flap is provided for controlling the proportion of cold air flowing into the mixing chamber and the proportion of warm air flowing into the mixing chamber, wherein the mixing flap is arranged rotatable about an axis and is driven by a flap actuator which has a drive shaft, wherein a gear with a nonlinear translation characteristic is provided between the mixing flap and the drive shaft.

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.

An air-conditioning unit includes an air-conditioning case including an opening through which air flows, a cooler disposed in the air-conditioning case to cool air flowing to the opening, a heater disposed in the air-conditioning case to heat air flowing to the opening, and an adjusting member disposed to cover the opening and adjusting airflow passing through the opening. The adjusting member is produced separately from the air-conditioning case and includes a first region and a second region. The second region includes a high resistance member giving higher resistance to the airflow than the first region. The first region includes a low resistance member giving lower resistance to the airflow than the second region. The low resistance member is a partition dividing the first region into plural air passing parts through which air flows. The high resistance member is a plate member including a part to interfere the airflow.

An air conditioner is configured to be switchable between a heating mode and a cooling mode. In the cooling mode, a high-temperature heat medium circulates between a high-pressure side refrigerant-heat medium heat exchanger and a high-temperature heat medium-outside air heat exchanger in a state where a refrigerant circulates in an air-cooling heat exchanger. In the heating mode, the high-temperature heat medium circulates between the high-pressure side refrigerant-heat medium heat exchanger and an air-heating heat exchanger, while a low-temperature heat medium circulates between a low-pressure side refrigerant-heat medium heat exchanger and a low-temperature heat medium-outside air heat exchanger, in a state where the refrigerant circulates in the low-pressure side refrigerant-heat medium heat exchanger.

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 a circumference of the first connection pipe and made of an elastic body, wherein the first main body and the second main body may be spaced from each other with a predetermined distance.

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.

Systems and methods are provided for thermal control using vascular channels. Vascular channels are incorporated in a network within a component. The component is a part of a manufactured environment configured for occupants. A fluid circuit is connected with the vascular channels and circulates a fluid through the component to alter a thermal state of the component.

A door actuating device includes a plurality of doors disposed in a flow channel for adjusting a degree of opening of the flow channel defined in an air conditioner case, the doors having respective door drive shafts, and a link unit actuating at least two of the doors. The link unit includes an actuator, a plate-like base member having two surfaces, a link mechanism having a plurality of levers mounted on at least either one of the two surfaces of the base member, and a rack member movably disposed on the base member and movable by a drive force transmitted from the actuator.
