Unsourced material may be challenged andremoved.This liquid can then be circulated through a heat exchanger to cool equipment, or anotherprocess stream such as air or process water. Most common today are the hermetic scroll,semihermetic screw, or centrifugal compressors. The condensing side of the chiller can be either airor water cooled. Even when water cooled, the chiller is often cooled by an induced or forced draftcooling tower.Water chillers can be watercooled, aircooled, or evaporatively cooled.The water isthen recirculated to the chiller to be recooled. These cooling coils transfer sensible heat and latentheat from the air to the chilled water, thus cooling and usually dehumidifying the air stream.Rentalchillers are mounted on a trailer so that they can be quickly deployed to the site.Industrial chillersare used for controlled cooling of products, mechanisms and factory machinery in a wide range dar-detector-manual.pdf

They are often used in the plastic industries, injection and blow molding, metal working cutting oils,welding equipment, diecasting and machine tooling, chemical processing, pharmaceuticalformulation, food and beverage processing, paper and cement processing, vacuum systems, Xraydiffraction, power supplies and power generation stations, analytical equipment, semiconductors,compressed air and gas cooling. They are also used to cool highheat specialized items such as MRImachines and lasers, and in hospitals, hotels and campuses.Each approach has its advantages. It isalso possible to have a combination of both centralized and decentralized chillers, especially if thecooling requirements are the same for some applications or points of use, but not all.Water chillerscan be watercooled, aircooled, or evaporatively cooled. Watercooled chillers incorporate the use ofcooling towers which improve the chillers thermodynamic effectiveness as compared to aircooledchillers. This is due to heat rejection at or near the airs wetbulb temperature rather than the higher,sometimes much higher, drybulb temperature. Evaporatively cooled chillers offer higher efficienciesthan aircooled chillers but lower than watercooled chillers.Aircooled machines are directly cooled byambient air being mechanically circulated directly through the machines condenser coil to expelheat to the atmosphere. Evaporative cooled machines are similar, except they implement a mist ofwater over the condenser coil to aid in condenser cooling, making the machine more efficient than atraditional aircooled machine. No remote cooling tower is typically required with either of thesetypes of packaged aircooled or evaporatively cooled chillers.The deep water source cooling system inToronto, Ontario, Canada, is an example. It uses cold lake water to cool the chillers, which in turnare used to cool city buildings via a district cooling system.The return water is used to warm the citys drinking water supply, which is desirable in this coldclimate. Whenever a chillers heat rejection can be used for a productive purpose, in addition to thecooling function, very high thermal effectiveness is possible.Using electric motors in a semihermeticor hermetic configuration is the most common method of driving the compressors since electricmotors can be effectively and easily cooled by the refrigerant, without requiring fuel supply orexhaust ventilation and no shaft seals are required, reducing maintenance, leaks, operating costsand downtime. They produce their cooling effect via the reverseRankine cycle, also known asvaporcompression. With evaporative cooling heat rejection, their coefficients of performance COPsare very high; typically 4.0 or more.The capacity of the compressor,The mechanism for compressing

refrigerant gas differs betweenCommon refrigeration compressors includeThese can be powered byelectric motors, steam turbines, orCompressors can also be either. Hermetic welded closed orsemihermetic bolted together.The first VSD was applied to centrifugal compressor chillers in thelate 1970s andNow, VSDs are being applied to rotary screwThe condenser is a heat exchangerwhichAir cooled condenser areWith evaporative coolingWater cooled condensers are cooled withwater that is in turn cooled by a cooling tower.The RMD is located immediately prior to theevaporator so that the cold gas in the evaporator can absorbThere is a sensor for the RMD on theevaporator outlet side whichThe evaporator is a heat exchanger which allowsDuring the statechange of the remainingCompared to electrically powered chillers, an absorption chiller has verylow electrical power requirements very rarely above 15 kW combined consumption for both thesolution pump and the refrigerant pump. However, its heat input requirements are large, and itsCOP is often 0.5 singleeffect to 1.0 ector-manual.pdfFor the same tonnage capacity, an absorption chiller requires a much larger cooling tower than avaporcompression chiller.It is the strong affinity that these two substances have for one another thatmakes the cycle work. The entire process occurs in almost a complete vacuum.From here, ahermetic solution pump moves the solution through a shell and tube heat exchanger for preheating.The solution surrounds a bundle of tubes which carries either steam or hot water. The steam or hotwater transfers heat into the pool of dilute lithium bromide solution. The solution boils, sendingrefrigerant vapor upward into the condenser and leaving behind concentrated lithium bromide. Theconcentrated lithium bromide solution moves down to the heat exchanger, where it is cooled by theweak solution being pumped up to the generator. The refrigerant vapor condenses on the tubes. Theheat is removed by the cooling water which moves through the inside of the tubes. As the refrigerantcondenses, it collects in a trough at the bottom of the condenser. The strong lithium bromidesolution actually pulls the refrigerant vapor into solution, creating the extreme vacuum in theevaporator. The absorption of the refrigerant vapor into the lithium bromide solution also generatesheat which is removed by the cooling water. Now the dilute lithium bromide solution collects in thebottom of the lower shell, where it flows down to the solution pump.The internal tank helps maintaincold water temperature and prevents temperature spikes from occurring. Closedloop industrialchillers recirculate a clean coolant or clean water with condition additives at a constant temperatureand pressure to increase the stability and reproducibility of watercooled machines andinstruments.The liquid is drawn from the tank, pumped through the chiller and back to the tank. Inindustrial water chillers is the use of water cooling instead of air duty-black-ops-user-manual.pdfIn this case the condenser does not cool the hot refrigerant with ambient air, but uses water that iscooled by a cooling tower. This development allows a reduction in energy requirements by morethan 15% and also allows a significant reduction in the size of the chiller, due to the small surfacearea of the waterbased condenser and the absence of fans.For medium to large chillers this shouldrange from 3.5 to 7.0, with higher values meaning higher efficiency.Other important specificationsinclude the internal water tank size and materials and full load current.Larger chillers will typicallyrequire an array of sound attenuators sometimes known as a silencer bank.Many refrigerantsoptions are available; when selecting a chiller, the application cooling temperature requirementsand refrigerants cooling characteristics need to be matched. Important parameters to consider arethe operating temperatures and pressures.This is a key consideration in intermittent applicationswhere a large chiller may last for 25 years or more. Ozone depletion potential ODP and globalwarming potential GWP of the refrigerant need to be considered.CO 2 is the GWPreferenceRetrieved 20080521.
