Chillers are large equipment with high technology and high efficiency that provide performance and safety. They are used in various industries, such as food, chemicals, mining, metallurgical machinery, and in various services, such as hospitals. They are classified by type, the main types of chillers are water cooled and air cooled. Both are advantageous and have low energy consumption and very wide temperature variation possibilities. See below for more information about each of them:
Its power is measured in tons of cooling capacity (TR), which is equivalent to 12,000 BTU/h per ton of cooling capacity (TR). Chillers can be centrifugal, screw and scroll compressors with capacities from 20 to 4,000 TR. As a result, its capacity is far superior to any split unit with a maximum capacity of 60,000 BTU/hr. Chillers normally maintain the water temperature between 6ºC (outlet) and 12ºC (return). However, using antifreeze additives such as ethylene glycol, these systems can operate in sub-zero temperatures. How many basic components does a chiller have? A chiller consists of 4 basic components of a refrigeration system: compressor, condenser, expansion device and evaporator.
