What is an AC Compressor and How Does it Work?
The AC compressor is a vital component of your 2007 Honda Odyssey’s air conditioning system. It is responsible for compressing the refrigerant gas, which allows it to release heat and cool down the air before it enters the cabin. Understanding the inner workings of the AC compressor will help you troubleshoot any issues that may arise.

The AC compressor operates based on a simple principle: the refrigerant gas is compressed, causing its pressure and temperature to rise.
As the gas moves through the compressor, it releases heat to the surrounding environment, leading to a decrease in temperature. This cooled refrigerant is then sent to the condenser, where it releases more heat and transforms back into a liquid state.
The liquid refrigerant then flows through the expansion valve, where it undergoes a pressure drop, allowing it to evaporate and absorb heat from the cabin air. Finally, the cycle repeats as the refrigerant returns to the compressor.
The AC compressor is driven by a belt connected to the engine’s crankshaft. When you turn on the air conditioning system, the compressor clutch engages, causing the compressor to start working.
It is important to note that the AC compressor relies on proper refrigerant levels and lubrication to function effectively. Lack of refrigerant or inadequate lubrication can lead to compressor failure and other AC system issues.
Key Points:
- The AC compressor compresses the refrigerant gas, cooling it down before it enters the cabin.
- Compressed gas releases heat, which is subsequently released by the condenser.
- The refrigerant undergoes pressure drops and evaporation to absorb heat from the cabin air.
- The AC compressor is driven by a belt connected to the engine’s crankshaft.
- Proper refrigerant levels and lubrication are essential for the compressor’s optimal functioning.
