Understanding the Basics of AC Compressors
What is an AC Compressor?
An AC compressor is a vital component of a vehicle’s air conditioning system. It is responsible for compressing and circulating refrigerant gas, allowing the air conditioning system to cool the air that enters the vehicle’s cabin. Without a functioning compressor, the AC system would not be able to produce cold air, making it an essential part of the vehicle’s comfort system.
How Does the Denso 447220-4771 AC Compressor Work?
The Denso 447220-4771 operates as a positive displacement compressor, specifically designed to handle the high-pressure demands of automotive air conditioning systems. It works by compressing the refrigerant gas (typically R-134a) and forcing it through the system, where it undergoes condensation and cooling before being released into the vehicle’s interior.
This compressor uses a 10S17C type, which refers to the size and displacement of the compressor. The “10S” indicates a 10-cylinder swash plate design, which is known for its efficiency and smooth operation. The “17C” refers to the displacement volume of 170 cubic centimeters per revolution.
