Chillers are further categorized by the type of compressor technology used: (1) centrifugal, (2) scroll, (3) reciprocating, and (4) screw. CdCondensers Air Cooled Water Cooled Tube and fin Shell and … Medium sized buildings with a cooling load of around 200 – 400 tons of refrigeration or 700 – 1,400 kW will typically use screw compressors or Turbocor compressors, these can be either water or air cooled, we’ll look at why that would be just shortly. Refrigeration compressors and air conditioning compressors provide air conditioning, heat pumping, and refrigeration for large-scale facilities and equipment. Rotary compressors are either rotating blade or stationary blade. Different types of process chillers fall under two main categories: (1) Vapor Absorption  and (2)Vapor Compression. different types of unloading refrigeration compressor with best price and finish evaluation from a variety item for all item. Typically, available in 150 – 6,000 TR, 530 – 21,000 kW, Typically use only one compressor sometimes two for exceptionally large capacity, Work best at full loading, VFD can e fitted to improve part load, Use one or two rotating impellors to compress the refrigerant and force it around the chiller, Capacity control through speed control and vane guides, Used in all cooling loads from large to small buildings, Typically, available in 60 – 1500 TR, 210 – 5,200 kW, One or more compressors used, staged and speed varied, Variable speed controller, soft starter, magnetic bearings, only one moving part, oil free, Use two rotating impellors to compress the refrigerant, Air or water cooled chillers – old technology, less common now, Used in small to medium cooling loads – common in simple low-cost refrigerators, Typically available in 50 – 500 TR, 170 – 1,700 kW, Use a piston and chamber to compress refrigerant, Capacity control through compressor staging or cylinder unloading and speed control, Typically, available 40 – 400 TR, 140 – 1,400 kW, Air cooled COP 3.2 – 4.86 Water cooled COP 4.45 – 6.2, One or more compressors, fixed or variable speed, staged or speed controlled. Small building with cooling loads under 200 tons or 700 kW will typically use scroll compressors or Turbocor compressors and are typically of air cooled design. These are the most common types of chillers. The different compressor technologies currently available – Chiller types and application guide, […] is the most energy intensive part, that being the compressor. As the name implies, it uses centrifugal force to pull in the refrigerant gas and then spins it rapidly with an impeller to compress it. Types of Air Compressor. Water cooled chillers generally last longer because they are inside the building so deteriorate much slower. This liquid can then be circulated through a heat exchanger to cool air or equipment as required. Scroll compressors are used in both air and water coolers. Temperature Control in Plastics Manufacturing. Capacity controlled via momentarily separating scrolls with solenoid valve and electronic modulation, Air cooled COP 2.9 – 4.15 Water cooled COP: 4.7 – 6.07, Typically, 1 compressor on water cooled, 1 or 2 compressors on air cooled, Uses two interlocking rotating helical rotors to compress the refrigerant, capacity is controlled via speed control or slider, Use heat to drive the refrigeration process, usually steam or hot water, Used in Medium to large buildings, Hospitals, Swimming centres, Heat Networks, No compressor, direct or indirect fired. One has blades or vanes that rotate with the shaft. Based on the working principle, refrigeration systems can be classified as vapor compression systems, vapor absorption systems, gas cycle systems, etc. It is mandatory to procure user consent prior to running these cookies on your website. Vapour compression chillers use an electrically driven mechanical compressor to force a refrigerant around the system. In this article we’ll be covering the different types of chillers available, where they are used as well as the pros and cons of each chiller type along with some examples of where they’re used. (Read more about how chillers work here.). The working principle for both air cooled and water cooled chillers is the same. Vapor compression chillers are the most common and include (1) air chillers and (2) water/fluid chillers. A compressor pushes a refrigerant round the inside of the chiller between the condenser, expansion valve, evaporator and back to the compressor.

All refrigeration systems work by transferring heat around, moving it from a designated area to somewhere else, thus cooling that designated area off and reversing the natural flow of heat with the application of energy.
