Piston compressors will have more moving parts and more frictional losses as compared to screw. They are commonly used to replace piston compressors where large volumes of high-pressure air are needed, either for large industrial applications such as chillers, or to operate high-power air tools such as jackhammers and impact wrenches. Think of compressor like your heart—as your heart pumps blood throughout the body, the compressor pumps refrigerant through the air conditioning system. R-32 Fixed Speed Rotary KV / RV / RVT / PV / PVT / NVT. It is suitable for any Air Conditioning application. Twin rotary compressor structure has been adapted to reduce in size to minimize vibration. Inlet-valve modulation, as used on lubricant-injected rotary air compressors, allows compressor capacity to be adjusted to match demand. The vane splits the space between the cylinder and the rolling piston into two sections (suction and discharge). Developed mini compressor has weight and volume about 20% compared to reciprocating compressor which has same capacity. The two common types of air compressors systems you will find in the market are the rotary screw air compressors and the reciprocating compressor. The compressor is used to expel heat out of the room by compressing refrigerant coming from the evaporator of the AC. What are twin screw compressors?

A rotary-screw compressor is a type of gas compressor, such as an air compressor, that uses a rotary-type positive-displacement mechanism. Okoma et al, 1990). This is the expansion of cost competitive inverter twin rotary compressor (SNB220). For heavy-duty, high horsepower needs, a rotary screw could be your best bet. The twin screw type compressor consists of two mating helically grooved rotors, one male and the other female. A rotary-vane compressor is also known as a rotary piston compressor because the function of the vane is similar to that of a piston (shown in Figure 3). Rotary Compressors. And a rotary unit cools its air at a slower rate than the scroll compressor. They have less maintainance cost and are small in size.
