A compressor is a key component of your HVAC system that compresses the refrigerant, allowing it to move through the coils and enable heat transfer. A scroll compressor, also known as a spiral compressor, is a type of compressor that uses scroll-shaped metal pieces to compress the refrigerant instead of a traditional piston. Due to their design, scroll compressors are more energy-efficient, produce fewer vibrations, and operate more quietly, making them a popular choice for modern HVAC systems.
How Does a Scroll Compressor Work?
The scroll compressor uses two scrolls to compress refrigerant. One scroll is fixed in place (the stationary scroll), while the other (the orbiting scroll) moves in a circular, smooth motion. As the orbiting scroll moves, it draws in refrigerant gas and compresses it. This increases the refrigerant’s pressure and temperature, and it is then sent to the condenser coil. Here, the refrigerant releases the absorbed heat outdoors.
Benefits of Using a Scroll Compressor
Compared to traditional piston compressor, scroll compressor offers several key advantages:
- Scroll compressors use a continuous, smooth compression process that requires less energy to operate. This improved efficiency can help reduce long-term energy costs.
- They are often quieter and smoother than piston compressors because compression occurs in a continuous motion rather than sharp strokes, reducing vibration and noise.
- With a simple design that includes fewer moving parts, scroll compressors experience less friction and wear.
