In industrial application, chilled water or other liquid from the chiller is pumped through process or laboratory equipment.
Industrial chiller technology
Industrial chillers typically come as complete, packaged, closed-loop systems, including the chiller unit, condenser, and pump station with recirculating pump, expansion valve, no-flow shutdown, internal cold water control. The internal tank helps maintain cold water temperature and prevents temperature spikes from occurring. Closed-loop industrial chillers recirculate a clean coolant or clean water with condition addititives at a constant temperature and pressure to increase the stability and reproducibility of water-cooled machines and instruments. The water flows from the chiller to the application's point of use and back.
Industrial chiller selection
Vapor-compression chiller technology
Important specifications to consider when searching for industrial chillers include the total life cycle cost, the power source, chiller IP rating, chiller cooling capacity, evaporator capacity, evaporator material, evaporator type, condenser material, condenser capacity, ambient temperature, motor fan type, noise level, internal piping materials, number of compressors, type of compressor, number of fridge circuits, coolant requirements, fluid discharge temperature, and COP (the ratio between the cooling capacity in RT to the energy consumed by the whole chiller in KW). For medium to large chillers this should range from 3.5-7.0 with higher values meaning higher efficiency. Chiller efficiency is often specified in kilowatts per refrigeration ton (kW/RT).

Process pump specifications that are important to consider include the process flow, process pressure, pump material, elastomer and mechanical shaft seal material, motor voltage, motor electrical class, motor IP rating and pump rating. If the cold water temperature is lower than −5°C, then a special pump needs to be used to be able to pump the high concentrations of ethylene glycol. Other important specifications include the internal water tank size and materials and full load current.

Control panel features that should be considered when selecting between industrial chillers include the local control panel, remote control panel, fault indicators, temperature indicators, and pressure indicators.

thermoelectric module chiller technology
A thermoelectric module "pumps" heat from one ceramic face to the other ceramic face when DC current is applied. Unlike the compressor in a standard refrigeration system that pumps Freon, thermoelectric modules use electrons to transfer heat.  Thermoelectric modules can also work in reverse, generating DC current (power) if one side is hot and the other is cold.

Use in industry
Chilled water is used to cool and dehumidify air in mid- to large-size commercial, industrial, and institutional (CII) facilities. Water chillers can be water-cooled, air-cooled, or evaporatively cooled. Water-cooled chillers incorporate the use of cooling towers which improve the chillers' thermodynamic effectiveness as compared to air-cooled chillers. This is due to heat rejection at or near the air's wet-bulb temperature rather than the higher, sometimes much higher, dry-bulb temperature. Evaporatively cooled chillers offer higher efficiencies than air-cooled chillers but lower than water-cooled chillers.
Water-cooled and Air-cooled
Water-cooled chillers are typically intended for indoor installation and operation, and are cooled by a separate condenser water loop and connected to outdoor cooling towers to expel heat to the atmosphere.
Air-cooled and evaporatively cooled chillers are intended for outdoor installation and operation. Air-cooled machines are directly cooled by ambient air being mechanically circulated directly through the machine's condenser coil to expel heat to the atmosphere. Evaporatively cooled machines are similar, except they implement a mist of water over the condenser coil to aid in condenser cooling, making the machine more efficient than a traditional air-cooled machine. No remote cooling tower is typically required with either of these types of packaged air-cooled or evaporatively cooled chillers.
Whole and split
Chiller需要排放從被冷卻對象取得的熱量,Chiller本體與排熱部分在同一個框架中的稱為一體式,分離的稱為分體式。雖然一體式占地麵積少,但設置在室內排熱會對室內溫度產生影響。 通常分體式將Chiller本體放在室內,排熱部分放置在室外。


在水會凍結的低溫域,或者在水會蒸發的高溫域,需要選擇水以外的液體
▋乙二醇/水溶液
冰點-12.6℃,能與水以任意比例混合,用作溶劑、防凍劑。
選擇乙二醇作為循環液需要的注意事項

  1. 冰點隨著乙二醇在水溶液中的濃度變化而變化,濃度在59%以下時,水溶液中乙二醇濃度升高冰點降低,但濃度超過59%後,隨著乙二醇濃度的升高,冰點呈上升趨勢,當濃度達到100%時,冰點上升至-13℃。
  2. 乙二醇含有羥基,長期在80℃~90℃下工作,容易氧化成酸,對水箱、水套造成腐蝕而使之滲漏。因此,在配製的防凍液中,還必須有防腐劑,以防止對鋼鐵、鋁的腐蝕和水垢的生成。

▋氟化液體
3M™ Novec™Galden® PFPE 都是高性能、惰性、氟化液體,用於導熱以及電氣和電子及半導體市場的各種高技術應用。氟化係列液體冰點可做到-100℃以下,沸點可做到100℃以上。
選擇氟化液體作為循環液需要的注意事項

  1. 不可與其他液體混合,價格昂貴
  2. 比重大於水,其動粘度根據使用溫度帶會小於水。由於液體的特殊性在選擇特殊泵頭或對循環結構進行特殊設計。


1)確定被控物體的發熱量及循環液體的流量
Chiller是利用液體循環從被控對象移除熱量,使被控物體恒定在某個溫度。因此在選擇Chiller時需要確定
◆多少流速(升/分鍾或立方米/小時)的液體在被控物體的入口和出口會有多少度℃溫差,從而計算出被控物體的發熱量,來選擇Chiller的製冷功率。
◆已知被控物體的發熱量,給出允許被控物體的入口和出口最大溫差,選擇Chiller水泵的流量。
