While the water-cooled chiller may be more energy-efficient, it receives stiff competition from air-cooled chiller in terms of installation cost, maintenance cost, number of equipment, and several other aspects. Most importantly, air-cooled chillers avoid water consumption so they are the ideal alternatives in areas with water scarcity or areas with cheap energy but costly water fees. Give us a call today for the most specialized and customized attention. If you enjoyed this post, you maybe want to know different heat rejection condensing technologies. Air-cooled chillers are refrigeration systems used in both commercial and industrial facilities to cool fluids and/or dehumidify air. They are used in a wide variety of settings including hotels, corporate events, restaurants, sporting events, large-scale construction, industrial and manufacturing plants, and so forth.
Each chiller is custom built to efficiently support your specific process cooling requirements. The industrial series chillers can accommodate a large range of process supply temperatures while operating in a wide range of ambient temperatures. This is because water cooled chillers produce lower condensing temperature than air cooled chillers. Refrigeration compressors are essentially a pump for refrigerant gas. The capacity of the compressor, and hence the chiller cooling capacity, is measured in kilowatts input , Horse power input , or volumetric flow (m3/h, ft3/h). The mechanism for compressing refrigerant gas differs between compressors, and each has its own application. Common refrigeration compressors include reciprocating, scroll, screw, or centrifugal. These can be powered by electric motors, steam turbines, or gas turbines. Compressors can have an integrated motor from a specific manufacturer, or be open drive–allowing the connection to another type of mechanical connection. Air-cooled and evaporative cooled chillers are intended for outdoor installation and operation.
Offered by KIG in October 2019 was this nice 2000 AEC/Sterlco 15 ton air cooled chiller. Refurbished and tested at our Clinton, MA shop, where it was cleaned, painted, checked and leak tested, and run for several days and monitored. 460v, 3p, power, has scroll compressor, and 30°F to 65°F fluid temperature range. This is an indoor chiller, yet the exhaust can be ducted outside if you choose . We have provided dozens and dozens of these units over the years and they are well-built true workhorses. Arrived at KIG in September 2014 was this 15 ton Air Cooled Chiller made by Affinity. This is an outdoor rated chiller , and has VFD drives for the fans, for low ambient year round outdoor process cooling capability. This unit was run and tested at KIG prior to shipping, and a run-off video provided, with money back guarantee of functionality. Air chillers can be split in various configurations or used as a single piece unit. Air chillers vary in size from small capacity to 100+ ton models that are used to cool commercial buildings.

Air-cooled chillers, chillers where water used in the chiller gets cooled by releasing heat into the ambient air through condensers, are popular in many industries. They don’t require cooling towers, and they don’t use as much water. However, every company needs something different from their chillers, and that means that you sometimes need to have your chiller customized. Water-cooled condensers perform the same function as air-cooled condensers, but require two steps to complete the heat transfer. First, heat moves from refrigerant vapor into the condenser water. Then, the warm condenser water is pumped to a cooling tower where the process heat is ultimately discharged to the atmosphere. A chiller works on the principle of vapor compression or vapor absorption.
These cooling coils transfer sensible heat and latent heat from the air to the chilled water, thus cooling and usually dehumidifying the air stream. Chilled water temperatures can range from 1 to 7 °C (34 to 45 °F), depending upon application requirements. Chiltrix uses a variable speed pump for the hydronic loop circulation. When full water flow is not needed due to off-peak capacity requirements, the water pump slows down and uses less energy. The variable speed pump and variable speed compressor work in tandem with the system controller using a special algorithm to keep the compressor and pump both working at the optimum speed. The variable speed condenser fan is controlled in a similar manner. This allows all of the consumers of electrical power within the chiller to operate at the lowest power level to meet the current load. Dynamically controlling the water pump speed and compressor speed independently of each other helps us to achieve the highest levels of performance. In addition, Chiltrix offers DC-Inverter indoor fan coil units, further reducing electrical power consumption . Air cooled chillers are typically located in mechanical equipment rooms or in an area of the building that is close to the spot it is cooling.

Request a quote from our team today to learn how we can help with your process cooling needs. Some users may prefer these chillers because of the smaller size they occupy as compared to air-cooled chillers. These chillers also feature higher efficiency and last longer than the mentioned alternative. Those who would like the equipment to be placed indoors may find the water-cooled machine desirable. Consume approximately 10% more power than a water-cooled unit due to wet surfaces transferring heat better than dry surfaces. Aqua Series chillers make their noise in the marketplace, not the workplace. The AquaSnap chiller’s low-sound AeroAcoustic® fan produces up to half the sound level of the propeller fan.
The final takeaway is that water-cooled chillers have a longer life, higher efficiency, larger capacity and refrigerant containment. Air-cooled chillers have a lower efficiency, yet are getting much better with technology advances, lower maintenance costs and less to install.
