Conjunto lógico FAW para sistema de tubulação de entrega de refrigerante de ar condicionado: 21 Partes Críticas Explicadas

Bem-vindo a esta análise técnica aprofundada do Conjunto lógico FAW para sistema de tubulação de entrega de refrigerante de ar condicionado (Conjunto 715). Este é o completo, 21-tipo de componente, “arterial network” for the ‘Automatic A/C’ (Conjunto 710) no FAW Jiefang CA4251P66K24T1A3E5 6×4 trator. Este é o “lógica” assembly responsible for safely transporting high-pressure refrigerant (gas and liquid) between the four main A/C components.

O “lógica” do Conjunto lógico FAW para sistema de tubulação de entrega de refrigerante de ar condicionado is to provide a sealed, durável, 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. Vamos desconstruir todo Conjunto lógico FAW para sistema de tubulação de entrega de refrigerante de ar condicionado em seu 21 tipos de componentes utilizáveis. Iremos analisar o “High-Pressure Logic” mangueiras, o “Low-Pressure Logic” mangueiras, o “Anchor Logic” of the brackets, e o crítico “Anti-Chafe” logic of the 21-piece hose, grampo, and fastener kit.

Essencial 1: O “High-Pressure” Lógica (Mangueiras 6 & 9) (O “Mais longo” Módulo)

O “High-Pressure” side is the “quente” side of the A/C system. Esta parte do Conjunto lógico FAW para sistema de tubulação de entrega de refrigerante de ar condicionado is responsible for carrying the refrigerant after it has been pressurized (and heated) by the compressor.

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

Este é o “Discharge Line.” This component has the hardest job in the entire Conjunto lógico FAW para sistema de tubulação de entrega de refrigerante de ar condicionado. Isso é “lógica” is to transport *hot, high-pressure gas*.

When the A/C compressor pressurizes the refrigerant, it becomes extremely hot (Por exemplo, 80° c / 176° f). This hose is designed with a “resistente ao calor” lógica. 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’ (Conjunto 714).

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

Este é o “Liquid Line.” After the ‘Condenser’ (714) has cooled the hot gas, isto “condenses” into a *high-pressure liquid*. This hose’s “lógica” is to transport that liquid.

O “refrigerant bottle” (or ‘Liquid Reservoir,’ mounted by Component 11) is the next stop. This bottle’s “lógica” é ser um “receiver/drier.” It *stores* the liquid refrigerant and, mais importante, contains a “dessecante” bolsa. This desiccant “lógica” is to *absorb* any microscopic drops of water that have contaminated the system. A água é o #1 inimigo de um sistema A/C, as it can freeze at the ‘Expansion Bladder’ (709) and cause a blockage.

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

Esse “dual-pipe” logic is the “firewall” conexão. It is an assembly that carries the high-pressure liquid *to* the ‘Evaporator’ (709) and the low-pressure gas *from* the ‘Evaporator’.

Essencial 2: O “Low-Pressure” Lógica (Mangueiras 2, 3, 8)

Este é o “frio” lado do Conjunto lógico FAW para sistema de tubulação de entrega de refrigerante de ar condicionado.

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

Este é o “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.

O “lógica” of this hose is to be the *largest diameter* pipe in the Conjunto lógico FAW para sistema de tubulação de entrega de refrigerante de ar condicionado, as the gas is now “expanded.” It is also often covered in *black foam insulation*. Esse “insulation logic” é crítico: 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.

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

These are auxiliary hoses, likely part of the “independent cold air” system mentioned in ‘Assembly 710’. Deles “lógica” é para “tocar” into the main system to provide refrigerant to a secondary evaporator or cooling unit, a key feature of the Conjunto lógico FAW para sistema de tubulação de entrega de refrigerante de ar condicionado.

Essencial 3: O “Anchor & Proteção” Lógica (Componentes 5, 11, 13, 15, 18, 19)

Este grupo de componentes é o “infrastructure” do Conjunto lógico FAW para sistema de tubulação de entrega de refrigerante de ar condicionado. Isso é “lógica” é para “âncora” the components and “protect” the hoses.

O “Anchor” Lógica (Componentes 11, 13, 15):

The ‘Liquid reservoir fixed bracket assy’ (8108155-90U) and ‘Bracket’ (8108121-90U) são os “anchor logic.” Their sole purpose is to securely mount the ‘Refrigerant Bottle’ (Receiver/Drier) para o chassi. The ‘Drain hose fixed bracket’ (8100106-A01, *da Assembleia 710*) is also part of this group, showing the systems are integrated.

O “Anti-Chafe” Lógica (Componentes 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) são os “anti-atrito” lógica. These simple, cheap plastic/rubber components are used to securely fasten the hoses *away* from the frame, motor, and other hoses. A missing clip is the #1 cause of a “rub-through” vazar, which is the most common (and most preventable) A/C failure.

Essencial 4: O “Antivibração” Lógica do Fixador

The final group is the 14-piece fastener kit. O “lógica” of this entire kit is “antivibração” para proteger o Conjunto lógico FAW para instalação de equipamentos de ar condicionado.

Parafusos Combinados (1, 4, 7, 10, 13, 20): This system uses *six different types* of “Combinação” (combinação) parafusos, for a total of 9 parafusos. O “combination logic” means each bolt has a *captive, arruela de pressão pré-instalada*.

Nozes (12, 14) & Arruelas (16, 17): O “lógica” of the remaining hardware is “dual-lock.” The system uses ‘Hexagon nuts’ (which are “contraporcas”) in combination with ‘Spring washers’ (16) and ‘Washers’ (17). Esse “cinto e suspensórios” lógica (a lock washer + a lock nut) is for the highest-vibration areas (like the compressor), garantindo um “à prova de falhas” connection that cannot loosen.
