Rotary compressors are a type of mechanical device used to compress gases, commonly found in air conditioning and refrigeration systems. They work by using rotating elements to draw in air or refrigerant and compress it into a smaller volume, increasing its pressure. This process is efficient and helps maintain the desired temperature in various applications. These compressors are known for their compact design and quiet operation, making them popular in both residential and commercial settings. They can be powered by electricity or gas, and their reliability makes them a preferred choice for many HVAC systems, ensuring comfort in our homes and workplaces.
