Types of compressors used in HVAC systems.

 There are five main types of compressors used in HVAC systems.

- Reciprocating Compressors: These are suitable for small to medium-sized systems and are commonly used in residential and light commercial applications. They are known for their ability to handle high-pressure differentials, but they are also noisy and require more maintenance than other types of compressors.

- Scroll Compressors: These are highly efficient with minimal moving parts, resulting in reduced energy consumption and improved reliability. They are well-suited for residential and light commercial applications, including air conditioners, heat pumps, and refrigeration units.

- Rotary Compressors: These are commonly used in medium to large-scale HVAC applications, such as commercial buildings, industrial processes, and refrigeration systems. They offer compact designs, quiet operation, and high reliability.

- Centrifugal Compressors: These are capable of handling large volumes of refrigerant with high flow rates and moderate pressure differentials. They are commonly employed in central air conditioning systems for large buildings, such as shopping malls, hospitals, and office complexes.

- Screw Compressors: These are highly reliable and efficient but more suitable for larger applications due to their cost. They are known for their high capacity and low vibration levels.
