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需要排放从被冷却对象取得的热量,Chiller本体与排热部分在同一个框架中的称为一体式,分离的称为分体式。虽然一体式占地面积少,但设置在室内排热会对室内温度产生影响。 通常分体式将Chiller本体放在室内,排热部分放置在室外。


在水会冻结的低温域,或者在水会蒸发的高温域,需要选择水以外的液体
▋乙二醇/水溶液
冰点-12.6℃,能与水以任意比例混合,用作溶剂、防冻剂。
选择乙二醇作为循环液需要的注意事项

  1. 冰点随着乙二醇在水溶液中的浓度变化而变化,浓度在59%以下时,水溶液中乙二醇浓度升高冰点降低,但浓度超过59%后,随着乙二醇浓度的升高,冰点呈上升趋势,当浓度达到100%时,冰点上升至-13℃。
  2. 乙二醇含有羟基,长期在80℃~90℃下工作,容易氧化成酸,对水箱、水套造成腐蚀而使之渗漏。因此,在配制的防冻液中,还必须有防腐剂,以防止对钢铁、铝的腐蚀和水垢的生成。

▋氟化液体
3M™ Novec™Galden® PFPE 都是高性能、惰性、氟化液体,用于导热以及电气和电子及半导体市场的各种高技术应用。氟化系列液体冰点可做到-100℃以下,沸点可做到100℃以上。
选择氟化液体作为循环液需要的注意事项

  1. 不可与其他液体混合,价格昂贵
  2. 比重大于水,其动粘度根据使用温度带会小于水。由于液体的特殊性在选择特殊泵头或对循环结构进行特殊设计。


1)确定被控物体的发热量及循环液体的流量
Chiller是利用液体循环从被控对象移除热量,使被控物体恒定在某个温度。因此在选择Chiller时需要确定
◆多少流速(升/分钟或立方米/小时)的液体在被控物体的入口和出口会有多少度℃温差,从而计算出被控物体的发热量,来选择Chiller的制冷功率。
◆已知被控物体的发热量,给出允许被控物体的入口和出口最大温差,选择Chiller水泵的流量。
