Which compressor is best for chiller plant?

Centrifugal Compressors These compressors are also available in hermetic and open models, where the open construction offers higher efficiency. At rated load, centrifugal compressors are more efficient than both reciprocating and rotary-screw compressors.

What type of compressors are used in chillers?

Compressors used in YORK® Chillers include centrifugal, screw and scroll. Centrifugal compressors rely on centrifugal force to compress refrigerant vapor. These are ideal for complex projects with medium to large cooling loads, such as hospitals, universities or naval ships.

What are the four types of compressors for chiller systems?

Chase Chillers feature four different types of positive displacement compressors: reciprocating, rotary vane, scroll, and screw. The compressor type largely aligns with the size and capacity of the chiller itself. Continue reading below for more information on the basics of the different compressor types.

How does a compressor work in a chiller?

The gaseous refrigerant goes into the compressor which increases its pressure. The high-pressure refrigerant goes to the condenser which rejects the heat using cooling water from a cooling tower or air from the surroundings, condensing it into a high-pressure liquid.

What is the capacity of chiller?

Air-cooled chillers are limited in size to 500 tons of capacity, whereas water-cooled chillers range to almost 9,000 tons.

What are the 2 types of chillers?

Different Types of Chillers

  • Centrifugal Chillers: This type of chiller turns kinetic energy into static energy through compression.
  • Absorption Chillers: These chillers send steam or hot water through tubes, where they boil off the refrigerant and turn into vapor, which moves into the condenser.

How do I calculate chiller size?

Divide Q (BTUs per hour) by 12,000 (the number of BTUs in one ton of cooling capacity). This yields the chiller capacity required to handle the process heat load in tons per hour: Example: 240,000/12,000= 20 tons/hr.
