Recommended Compressor for Large Tonnage Air-Conditioning Applications


In large tonnage air-conditioning applications, where the cooling load exceeds 200 tons, the most suitable type of compressor is the centrifugal compressor.


Reciprocating Compressor


  • A reciprocating compressor uses a piston-cylinder arrangement to compress the refrigerant gas.

  • It is commonly used in small to medium-sized air-conditioning systems.

  • Reciprocating compressors are not recommended for large tonnage applications due to their limited capacity and efficiency.



Rotating Compressor


  • Rotating compressors, such as scroll and rotary compressors, use rotating mechanisms to compress the refrigerant gas.

  • While they have higher capacities compared to reciprocating compressors, they are still not suitable for large tonnage applications.

  • Rotating compressors are commonly used in residential and light commercial air-conditioning systems.



Screw Compressor


  • Screw compressors utilize two interlocking helical rotors to compress the refrigerant gas.

  • They have higher capacities and efficiencies compared to reciprocating and rotating compressors.

  • Screw compressors are commonly used in medium-sized air-conditioning systems.

  • However, for large tonnage applications, they may still not provide the required capacity and efficiency.



Centrifugal Compressor


  • A centrifugal compressor uses a high-speed impeller to accelerate the refrigerant gas and then converts the kinetic energy into pressure.

  • It is capable of handling large volumes of refrigerant gas and providing high capacities.

  • Centrifugal compressors are highly efficient and suitable for large tonnage air-conditioning applications.

  • They are commonly used in industrial and commercial air-conditioning systems, such as those found in large buildings, factories, and data centers.



In conclusion, for air-conditioning applications with a cooling load exceeding 200 tons, the recommended type of compressor is the centrifugal compressor. It offers the necessary capacity, efficiency, and reliability to meet the demands of such large tonnage systems.

Lubricants are essential for the performance and longevity of a refrigeration system. The choice of lubricant depends on the system, the refrigerant, and the type of application.There are several categories of oils:Mineral oils: They are particularly suited for use with CFC (R11, R12), HCFC (R22, R142b, R123) refrigerants, and ammonia.Alkyl Benzene Oils (AB): AB oils are especially recommended for refrigerants like R-22 and HCFC blends.Poly Alpha Olefins (PAO): It can be described as ‘mineral synthetic oils.’ PAO oils can be used in refrigeration systems working in extreme conditions with R-22 or ammonia. It has a low pour point and excellent thermal stability.Poly Alkylene Glycols (PAG): These were the first oils developed for use with HFC refrigerants and are perfectly miscible with these products.Polyol Ester Oils (POE): POE constitutes the second generation of lubricants developed for use with HFC’s (R134a, R152
