A refrigerant circulating apparatus for a vehicle, includes: at least one heat exchanger configured to heat-exchange a refrigerant; at least one valve provided to selectively flow the refrigerant to the at least one heat exchanger; and a refrigerant distribution unit having a first surface on which the at least one heat exchanger is mounted and a second surface on which the at least one valve is mounted, wherein the refrigerant distribution unit includes a plurality of flow paths therein to flow the refrigerant to the at least one heat exchanger according to selective operation of the at least one valve.

A method of manufacturing a transport refrigeration unit is provided. The method includes providing an enclosure including an outer layer and a supporter. Providing the enclosure includes supplying one of a first material and a second material to a mold. This also includes supplying the other of the first material and the second material on the one of the first material and the second material that is supplied to the mold. Also, this includes curing the first material and the second material integrally that are supplied to the mold. The first material forms into the outer layer and the second material forms into the supporter. The second material includes a plurality of reinforcing fibers.

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 transport refrigeration system is provided including a tractor vehicle having an engine and a trailer operably coupled to the tractor vehicle. A transport refrigeration unit is mounted to a front surface of the trailer adjacent the tractor vehicle. At least one shield is mounted to the tractor or the trailer and is configured to divert discharged hot air from a flow path towards a condenser air inlet of the transport refrigeration unit.

An air conditioner system for an electric motor mobility is provided. The air conditioner system is configured so that an external condenser is spaced from a radiator at a front portion of the mobility, the external condenser performs heat exchange with air introduced from a location other than the front portion of the mobility, so that an active air flap is controlled to be closed in an indoor heating condition. Therefore, as the air resistance is reduced while the mobility drives under the indoor heating condition, the air resistance is reduced and the aerodynamic performance of the mobility is improved.

An outdoor cooling unit for vehicular air conditioning apparatus includes: a casing including an outlet section, inlet sections having an inlet plane inclined; a first heat exchanger facing one of the inlet sections and a second heat exchanger facing an other of the inlet sections; at least one propeller fan below the outlet section to blow out air upwardly. An angle formed between the normal line to the inlet plane and the z axis is an acute angle. Each of the blades includes a blade chord center point on an inner peripheral end thereof and an other blade chord center point on an outer peripheral end thereof, positioned so that a line segment connecting therebetween has an inclination to the outlet section proportionally to closeness to outer periphery of the blade. A blade chord center line forms a curve being convex toward the outlet section across the entire area.

A new and improved air return bulkhead for a refrigeration cargo trailer is disclosed. The air return bulkhead comprises two primary components, a first upper panel component and a second lower panel component. The first upper panel component effectively defines a fluid conduit through which relatively warm return air is fluidically conducted into the refrigeration unit, while the second lower panel component comprises a structure upon which only a plurality of pallet stops are integrally formed. The second lower panel component is entirely separate from the upper panel component, and in this manner, whenever the pallet stops become damaged, only the used lower component needs to be simply detached and replaced. An upper edge portion of the first upper panel component is also provided with a blade member which will engage the rear face of the refrigeration unit along a linear locus extending across the entire horizontal extent or width of the refrigeration unit so that cooled or refrigerated air cannot effectively be sucked back into the inlet or intake portion of the refrigeration unit, thereby preventing the occurrence of “short cycling” of the refrigeration unit.

The present invention relates to an air conditioner system, in which an air-cooled condenser mounted on a refrigerant circulation line between a water-cooled condenser and an expansion valve and a blower fan for blowing air to the air-cooled condenser are arranged at one side of the water-cooled condenser in a state of being disposed in a row in the air flow direction and are arranged within the width of the one side of the water-cooled condenser, thereby enabling the enhancement of installability and assemblability inside an engine room by simplifying and reducing the package, reducing noise of the blower fan and securing adequate cooling performance because of the blower fan disposed between two air-cooled heat exchangers even when inflowing air is insufficient, such as in an idling condition.

A motor vehicle may have a cylindrical component having two grooves aligned orthogonally to a cylinder axis, recessed into local areas of a lateral surface, and running parallel to each other, and a blind hole in an end of the cylindrical component. A fastening component for the cylindrical component may include a holding device having a U-shaped socket and a head portion having a through opening. The holding device may be matched to the cylindrical component in such a way that the cylindrical component is positively insertable via the two grooves into the U-shaped socket until the blind hole in the end is in alignment with the through opening in the head portion of the holding device. The fastening arrangement may also have a fastening element that is insertable and screwable through the through opening in the head portion into the blind hole in the cylindrical component.

An ejector-type refrigeration cycle includes an ejector module integrated with a gas-liquid separation device. The ejector module is disposed outside an area that overlaps with an engine when viewed from a vehicular upper side. Further, the ejector module may be disposed outside an area overlapping with the engine when viewed from the vehicular front side, and the ejector module may be disposed outside of side members in a vehicle width direction.
