Air conditioning compressors
STRON, as one of the leading manufacturers of automotive air conditioning compressors, takes pride in its multi-stage and high-tech manufacturing process. Each compressor is the result of precise engineering calculations, careful selection of materials, and stringent quality control at every stage.
All air conditioning compressors undergo a multi-stage inspection at the factory immediately after manufacture. The components are subjected to functional testing for pressure, efficiency, and cooling performance. Additionally, tests are carried out to check the resistance of the windings, insulation, and to diagnose the casing's airtightness, as well as to inspect for defects and any noise during operation.
The heart of the compressor lies in its key components, for which STRON uses only high-quality materials. The compressor casing is made from a durable aluminium alloy, providing an optimal balance of weight, heat dissipation, and corrosion resistance.
Pistons and valves are manufactured from wear-resistant steel alloys with special coatings that minimise friction and extend their lifespan. The sealing rings, which are critical for the system's integrity, are made from specialised polymers that are resistant to high temperatures and refrigerants. Each component, from the crankshaft mechanism to the valve system, is assembled in sterile conditions. The use of specialised lubricants at every stage of assembly ensures smooth operation and protection against premature wear.
The STRON compressors are built on high-strength aluminium alloys, which feature excellent thermal conductivity and corrosion resistance. Critically important components, such as pistons, rotors, and bearings, are made from hardened steel with the application of specialised diamond coatings.
This ensures exceptional wear resistance and reduces the friction coefficient, which directly impacts the reduction of energy consumption and the lifespan of the compressor. The machining of components is carried out on high-precision CNC machines, guaranteeing adherence to micron tolerances.
The assembly process of STRON is a testament to engineering excellence in every detail. Automated production lines equipped with robotic technology and machine vision systems eliminate the possibility of error. Each component undergoes meticulous cleaning in ultrasonic baths before assembly. Special attention is paid to the sealing system. STRON utilises unique multi-layer rubber and polymer compositions designed for resistance to extreme temperatures and aggressive automotive refrigerants, ensuring absolute system integrity throughout its entire lifespan.
Installing a new air conditioning compressor in a car is a multi-step process that requires precision, specialised tools, and expertise.
- Dismantling the old compressor and preparing the system.
The first and most critical stage is the removal of the old compressor. Before disconnecting it, the refrigerant must be evacuated from the system using specialised equipment. Next, the electrical connections and high and low-pressure hoses are disconnected. After fully detaching the compressor housing, particular attention is paid to the cleanliness of the mating surfaces and flanges where the new unit will be installed. Removing any remnants of old seals and contaminants is crucial for ensuring a proper seal.
- Installation of the New Compressor and Connection
The new compressor is carefully positioned in place and secured using new sealing rings and gaskets. It's important to use the torque settings recommended by the manufacturer for the securing bolts. The pipes of the air conditioning system are then connected. When attaching the hoses, ensure they are oriented correctly to avoid kinks and internal stress. After the mechanical installation, the electrical connectors are attached.
- Leak Testing and System Charging
After the compressor is installed, the air conditioning system undergoes a vacuum process. This stage removes any remaining air and moisture from the system, which can cause corrosion and reduce efficiency. A leak test is then performed using a vacuum gauge. If the system maintains a vacuum, it is charged with the recommended type of refrigerant and compressor oil in accordance with the manufacturer's specifications. The final step involves testing the air conditioning system in all modes, monitoring pressure and temperature.
The car air conditioning compressor is a complex mechanical unit that plays a key role in maintaining a comfortable temperature in the vehicle's interior. It functions as a pump, responsible for circulating and compressing the refrigerant. Its design may vary depending on the type, but the general principles of operation and the main components remain similar.
The operation of the compressor is based on the process of compressing gaseous refrigerant. Under the influence of the car's engine, a pulley connected to the compressor's crankshaft rotates. By moving the pistons or rollers, the compressor draws in low-pressure gaseous refrigerant from the evaporator, compresses it into a high-pressure, high-temperature gas, and then pumps it into the condenser.
The main components of the compressor include:
- Housing: Typically made from a durable aluminium alloy, which serves as the foundation for all internal components and ensures airtightness.
- Working mechanism: This can be a piston mechanism (with one or several pistons), a rotary mechanism, a spiral mechanism, or a plate mechanism. It is this that is directly responsible for compressing the refrigerant.
- Drive pulley: Connected to the engine's drive belt, it provides rotation to the working components.
- Engagement clutch: The electromagnetic clutch, controlled by the climate control unit, connects the pulley to the compressor shaft, starting or stopping its operation.
- Valve system: The inlet and outlet valves regulate the flow of refrigerant, preventing its reverse movement.
- Lubrication system: Ensures a reduction in friction and wear of moving parts.
There are various types of compressors, each with its own design features:
- Reciprocating: The most common type, resembling an internal combustion engine. Pistons move within cylinders, compressing the refrigerant.
- Rotary: They have an eccentric rotor that rotates inside a cylinder.
- Spirals: Consist of two spirals, one of which rotates, moving and compressing the refrigerant.
- Plate-type: They use plates that create chambers for compressing the refrigerant during the rotation of the eccentric. Regardless of the type, all car air conditioning compressors are designed for reliable and long-lasting performance under varying loads and temperatures, ensuring a cool atmosphere in your vehicle's interior.
When manufacturing air conditioning compressors, STRON employs the latest equipment and standardised production processes in accordance with ISO/TS 16949. All products undergo testing at the factory upon leaving the production line, which enables STRON to have complete confidence in the quality of its products.
The company STRON knows its product, which is why all items come with an unconditional guarantee of 3 years or 80,000 kilometres of use. There is also a guarantee of compliance regarding applicability, dimensions, and fittings.
In the event of complaints, STRON takes responsibility for their resolution – the company provides the end customer with a replacement and reimburses the costs for reinstallation.
