A refrigerant hose has an innermost tube defining a lumen therein, and the innermost tube is based on one of a hydrogenated nitrile butadiene rubber (HNBR), an HNBR containing polymer blend, or a copolymer thereof, which is cured with a phenol-formaldehyde resin. The refrigerant hose may further include an optional permeation inhibiting layer which surrounds the innermost tube when incorporated, a reinforcing layer disposed outwardly from the innermost tube and the optional permeation inhibiting layer when this layer is used, and a cover layer disposed outwardly from the reinforcing layer. The innermost tube has a volume swell percentage of 10% or less when exposed to polyolester oil or polyalkylene glycol oil for 168 hrs @ 125° C. Additionally, the innermost tube is devoid of peroxide and may further be devoid added elemental sulfur, sulfur donors and/or additives containing sulfur within their molecular structures.

An air conditioning piping system of the disclosure includes a refrigerant pipe made of a plastic material and configured to provide a fluid flow between components constituting an air conditioning system; at least one connection flange made of the plastic material and configured to provide a connection between the refrigerant pipe and components constituting the air conditioner system; and at least one charging port made of the plastic material and having a charging valve configured to inject a refrigerant into the refrigerant pipe.

A holder for an interior trim part, in particular for covering the passenger compartment of a motor vehicle, has at least one supply line for guiding a temperature-controllable, liquid or gaseous fluid, to an outlet via which the fluid can emerge from the supply line, and an inlet via which the fluid can enter a discharge line. An interior trim part can be arranged on the holder in such a manner that the outlet of the holder is fluidically connected to an inlet of the interior trim part, and the inlet of the discharge line of the holder is fluidically connected to an outlet of the interior trim part.

The invention relates to a heating, ventilation and/or air-conditioning device (1) for a motor vehicle, characterised in that it comprises at least one first air circulation channel (3), at least one second air circulation channel (4), and means (5, 6) for generating an air stream in the first air circulation channel (3) and/or in the second air circulation cannel (4), the device (1) also comprising means for the inflow of a cleaning product (13, 16) ending in the first air circulation channel (3) and/or in the second air circulation channel (4).

Disclosed is a heat exchanger capable of exchanging heat between coolant and refrigerant of different kinds in one device and providing an effective heat exchange ratio between the coolant and the refrigerant. The heat exchanger includes a refrigerant flow path having a refrigerant inlet and a refrigerant outlet, and a coolant flow path through which coolant flows to exchange heat with the refrigerant. The coolant flow path includes a first coolant flow path where first coolant flows, and a second coolant flow path where second coolant with a different kind from the first coolant flows. The heat exchanger is partitioned into a first heat exchange section, in which the first coolant exchanges heat with the refrigerant and a second heat exchange section, in which the second coolant exchanges heat with the refrigerant, so that the heat exchange in the first heat exchange section and the heat exchange in the second heat exchange are carried out independently.

A heating, ventilation, and air cooling (HVAC) assembly including a blower subassembly and an HVAC subassembly. The blower subassembly includes a first heater core pipe retention member. The HVAC subassembly includes a second heater core pipe retention member. The first and the second heater core pipe retention members are configured to secure at least one heater core pipe therebetween.

A connector for a component fitting assembly of an air conditioning system includes a substantially planar plate having a recessed portion and a slot portion. The recessed portion and the slot portion are formed in the plate to define an opening for receiving a conduit therein. A method for coupling the conduit to the connector includes the step of urging at least the portion of the conduit through the slot portion and into the recessed portion of the plate, whereby the at least the portion of the conduit is deformed to correspond with a configuration of the opening to militate against disengagement between the plate and the at least the portion of the conduit disposed in the opening of the plate.

The present disclosure relates to an apparatus that has a conduit and an impact absorber assembly. The impact absorber assembly includes a core and a frame, where the core has an aperture configured to receive the conduit and the frame includes a cavity sized and shaped to receive the core. The frame also has a first side wall and a second side wall that are spaced apart to define, at least in part, a cavity. The first and second side walls also include an intermediate portion that includes a waveform shape. The waveform shape includes at least a pair of ridges and a trough between the ridges.

The absorbing device includes a hollow enclosed chamber including two pot parts. Open ends of the pot parts are connectable to each other by welding or soldering. Each of the pot parts is integrally formed in an opposing end of an air-conditioning conduit, wherein open ends of the pot parts are oriented toward each other. Each of the pot parts is provided with a reduced passage opening interconnected with an internal space of the air-conditioning conduit via a tapered section.

Provided is a layout structure of refrigerant piping near a heat accumulator in a vehicle, which is connected to the heat accumulator and can reduce cooling of the refrigerant piping near the heat accumulator due to blowing of wind that comes with running of the vehicle, thereby suppressing heat dissipation of the refrigerant flowing into and out of the heat accumulator. The heat accumulator mounted in a front portion of the vehicle is arranged to extend in a direction substantially orthogonal to a front-rear direction of the vehicle, and has refrigerant inflow part and outflow part at an end. The refrigerant piping includes inflow piping connected to the inflow part and outflow piping connected to the outflow part. The inflow piping and outflow piping are arranged to extend along a length direction of the heat accumulator in a state of being close to a back surface of the heat accumulator.
