4472504151 AC Parts Compressor 6SBU14C 7PK For Honda Accord 2019-2022 WXHD019

Installing a car AC compressor can be a relatively complex process that involves several steps. Here's a general outline of the installation process:

1. Gather Necessary Tools and Equipment: Before you start, make sure you have all the required tools and equipment. This may include wrenches, sockets, ratchet, refrigerant recovery machine (if necessary), new compressor, new O-rings, PAG oil, manifold gauge set, vacuum pump, and safety equipment like gloves and goggles.

2. Prepare the Vehicle: Ensure the vehicle is parked on a flat surface and turned off. Open the hood and locate the AC compressor, which is typically driven by a belt connected to the engine.

3. Relieve Pressure: If the AC system has any remaining refrigerant, it needs to be evacuated using a refrigerant recovery machine. This should only be done by a certified technician with the proper equipment to handle refrigerants safely.

4. Remove the Old Compressor: Disconnect the negative terminal of the battery to prevent electrical accidents. Remove the serpentine belt from the compressor pulley. Disconnect any electrical connectors or mounting bolts securing the compressor to the engine. Carefully remove the old compressor from its mounting brackets.

5. Prepare the New Compressor: Before installing the new compressor, transfer any necessary components from the old compressor to the new one, such as mounting brackets, sensors, or pulleys. Make sure to replace any O-rings or seals with new ones to prevent leaks.

6. Install the New Compressor: Position the new compressor in place and secure it with mounting bolts. Reconnect any electrical connectors. Install the serpentine belt back onto the compressor pulley and ensure it's properly tensioned according to the manufacturer's specifications.

7. Recharge the AC System: Connect the manifold gauge set to the high and low-pressure ports on the AC system. Use a vacuum pump to remove any air and moisture from the system, creating a vacuum. Once the system is evacuated, close the valves on the manifold gauge set and wait to see if the system holds the vacuum. If it does, charge the system with the appropriate amount of refrigerant according to the manufacturer's specifications.

8. Check for Leaks and Functionality: After recharging the system, start the engine and turn on the AC. Check for any leaks around the compressor or other components using a UV dye or leak detection tool. Ensure that the AC system is cooling properly and that all functions are working correctly.

9. Final Checks: Double-check all connections, belts, and system pressures to ensure everything is installed correctly and functioning properly.

10. Reconnect Battery: Once everything is confirmed to be in working order, reconnect the negative terminal of the battery.

If you're not experienced with automotive repairs, it's recommended to have a professional mechanic or technician perform the installation to ensure it's done correctly and safely. Additionally, handling refrigerants requires proper certification and equipment to comply with environmental regulations and ensure safety.

Compressors :

1) Rotary Vane - Panasonic

Rotary vane compressors consist of a rotor with three or four vanes and a carefully shaped rotor housing. As the compressor shaft rotates, the vanes and housing form chambers.

The R134a is drawn through the suction port into these chambers, which become smaller as the rotor turns. The discharge port is located at the point where the gas is fully compressed.The vanes are sealed against the rotor housing by centrifugal force and lubricating oil. The oil sump and oil pump are located on the discharge side, so that the high pressure forces oil through the oil pump and then onto the base of the vanes keeping them sealed against the rotor housing.

During idle an occasional vane noise from the compressor may be heard. This is due to the time taken for lubricating oil to circulate through the A/C system.

2)Scroll type - Sanden

This compressor uses a unique design with two scrolls, one fixed and one is movable, both are inter-leaved.The movable spiral is able to ORBIT or oscillate without actually fully rotating. The movable scroll is connected to the input shaft via a concentric bearing.

As the movable spiral oscillates within the fixed spiral, a number of pockets are formed between the spiral. As these pockets decrease in size the refrigerant is squeezed, the pressure increases and is discharged through a reed valve at the discharge port in the rear section of the compressor.

3)Variable stroke - Harrison V5

The Delphi (Harrison) V5 compressor is a non-cycling variable displacement compressor.

The compressor varies displacement to control capacity to meet A/C system demand at all operating conditions. The compressor features a variable angle wobble plate in five (V5) cylinder axial piston design.

Displacement is controlled by a bellows actuated control valve located in the rear cylinder head. This control valve senses and responds to the system suction pressure or A/C system demand.

Through regulation of compressor crankcase pressure, the wobble plate angle, and therefore compressor displacement is variable.

In general, the compressor discharge pressure is much greater than the compressor crankcase. Which is greater than or equal to the compressor suction pressure.

At maximum displacement, compressor crankcase pressure is equal to the compressor suction pressure.

At reduced or minimum displacement, the compressor crankcase pressure is greater than the suction pressure.
