Assemblée logique de FAW pour le système de tuyauterie de livraison de réfrigérant de climatisation: 21 Pièces critiques expliquées

Welcome to this in-depth technical analysis of the Assemblée logique de FAW pour le système de tuyauterie de livraison de réfrigérant de climatisation (Assemblée 715). C'est le complet, 21-component-type, “arterial network” for the ‘Automatic A/C’ (Assemblée 710) sur le FAW Jiefang CA4251P66K24T1A3E5 6×4 tracteur. C'est le “logique” assembly responsible for safely transporting high-pressure refrigerant (gas and liquid) between the four main A/C components.

Le “logique” de la Assemblée logique de FAW pour le système de tuyauterie de livraison de réfrigérant de climatisation is to provide a sealed, durable, and vibration-proof pathway. It connects the engine-mounted compressor to the ‘Condenser’ (714) at the front, the condenser to the ‘Liquid Reservoir’ (Component 11’s function), the reservoir to the in-cab ‘Evaporator’ (709), and the evaporator back to the compressor.

This expert guide is essential for HVAC technicians and parts specialists. Nous déconstruirons l'ensemble Assemblée logique de FAW pour le système de tuyauterie de livraison de réfrigérant de climatisation dans son 21 types de composants réparables. Nous analyserons le “High-Pressure Logic” tuyaux, le “Low-Pressure Logic” tuyaux, le “Anchor Logic” of the brackets, et la critique “Anti-Chafe” logic of the 21-piece hose, clip, and fastener kit.

Cœur 1: Le “High-Pressure” Logique (Tuyaux 6 & 9) (Le “Plus long” Module)

Le “High-Pressure” side is the “chaud” side of the A/C system. Cette partie du Assemblée logique de FAW pour le système de tuyauterie de livraison de réfrigérant de climatisation is responsible for carrying the refrigerant after it has been pressurized (and heated) by the compressor.

1. Composant 9: ‘Hose assy-high pressure-compressor to condenser’ (8108080-13A-C00)

C'est le “Discharge Line.” This component has the hardest job in the entire Assemblée logique de FAW pour le système de tuyauterie de livraison de réfrigérant de climatisation. C'est “logique” is to transport *hot, high-pressure gas*.

When the A/C compressor pressurizes the refrigerant, it becomes extremely hot (Par exemple, 80° C / 176° F). This hose is designed with a “résistant à la chaleur” logique. It is a multi-layer hose with an inner “barrier” (to prevent R134a/R1234yf permeation) and an outer EPDM rubber wrap to withstand intense engine bay heat and vibration. It carries this hot gas to the ‘Condenser’ (Assemblée 714).

2. Composant 6: ‘Hose assy-high pressure-condenser to refrigerant bottle’ (8108130-13A-C00)

C'est le “Liquid Line.” After the ‘Condenser’ (714) has cooled the hot gas, il “condenses” into a *high-pressure liquid*. This hose’s “logique” is to transport that liquid.

Le “refrigerant bottle” (or ‘Liquid Reservoir,’ mounted by Component 11) is the next stop. This bottle’s “logique” c'est être un “receiver/drier.” It *stores* the liquid refrigerant and, more importantly, contains a “desiccant” bag. This desiccant “logique” is to *absorb* any microscopic drops of water that have contaminated the system. Water is the #1 enemy of an A/C system, as it can freeze at the ‘Expansion Bladder’ (709) and cause a blockage.

3. Composant 21: ‘Dual pipe hose’ (8108153-90U)

Ce “dual-pipe” la logique est la “firewall” connection. It is an assembly that carries the high-pressure liquid *to* the ‘Evaporator’ (709) and the low-pressure gas *from* the ‘Evaporator’.

Cœur 2: Le “Low-Pressure” Logique (Tuyaux 2, 3, 8)

C'est le “cold” side of the Assemblée logique de FAW pour le système de tuyauterie de livraison de réfrigérant de climatisation.

Composant 8: ‘Hose assy-low pressure-evaporator to compressor’ (8108060-13A-C00)

C'est le “Suction Line.” After the liquid refrigerant boils in the ‘Evaporator’ (709), it becomes an *extremely cold, low-pressure gas*. This is the gas that has *absorbed* all the heat from the cab.

Le “logique” of this hose is to be the *largest diameter* pipe in the Assemblée logique de FAW pour le système de tuyauterie de livraison de réfrigérant de climatisation, as the gas is now “expanded.” It is also often covered in *black foam insulation*. Ce “insulation logic” est critique: it prevents the cold gas from “sweating” (condensing) and dripping water all over the engine bay, and it keeps the gas cold on its return trip to the compressor, which is essential for efficiency.

Composants 2 & 3: ‘Hose assy E’ (8108075-50UN) & ‘Hose assy A’ (8108065-50UN)

These are auxiliary hoses, likely part of the “independent cold air” system mentioned in ‘Assembly 710’. Leur “logique” est de “tap” into the main system to provide refrigerant to a secondary evaporator or cooling unit, a key feature of the Assemblée logique de FAW pour le système de tuyauterie de livraison de réfrigérant de climatisation.

Cœur 3: Le “Anchor & Protection” Logique (Composants 5, 11, 13, 15, 18, 19)

This group of components is the “infrastructure” de la Assemblée logique de FAW pour le système de tuyauterie de livraison de réfrigérant de climatisation. C'est “logique” est de “ancre” the components and “protect” the hoses.

Le “Anchor” Logique (Composants 11, 13, 15):

The ‘Liquid reservoir fixed bracket assy’ (8108155-90U) and ‘Bracket’ (8108121-90U) sont les “anchor logic.” Their sole purpose is to securely mount the ‘Refrigerant Bottle’ (Receiver/Drier) au châssis. The ‘Drain hose fixed bracket’ (8100106-A01, *de l'Assemblée 710*) is also part of this group, showing the systems are integrated.

Le “Anti-Chafe” Logique (Composants 5, 18, 19):

This is the *most critical service logic*. A/C hoses are made of aluminum and rubber; the chassis is vibrating steel. If they touch, the hose *will* rub through and leak.

The ‘Plastic retaining strap’ (T67427946), ‘Pipe clip’ (8108076-742), and ‘Pipe clip plate assy’ (8108075-742) sont les “anti-chafe” logique. These simple, cheap plastic/rubber components are used to securely fasten the hoses *away* from the frame, moteur, and other hoses. A missing clip is the #1 cause d'un “rub-through” leak, which is the most common (and most preventable) A/C failure.

Cœur 4: Le “Anti-vibrations” Logique de fixation

The final group is the 14-piece fastener kit. Le “logique” of this entire kit is “anti-vibration” to protect the Assemblage logique FAW pour l’installation d’équipements de climatisation.

Boulons combinés (1, 4, 7, 10, 13, 20): This system uses *six different types* of “Combinaison” (combinaison) boulons, for a total of 9 boulons. Le “combination logic” means each bolt has a *captive, rondelle frein pré-fixée*.

Noix (12, 14) & Rondelles (16, 17): Le “logique” of the remaining hardware is “dual-lock.” The system uses ‘Hexagon nuts’ (which are “lock nuts”) in combination with ‘Spring washers’ (16) and ‘Washers’ (17). Ce “belt-and-suspenders” logique (a lock washer + a lock nut) is for the highest-vibration areas (like the compressor), assurer un “failsafe” connection that cannot loosen.
