For this reason, you will usually only find them in large buildings. This is because the energy savings outweigh the cost of installing and maintaining the system. Chillers use the refrigeration cycle to remove heat from chilled waterA chilled water system’s refrigeration cycle works by removing heat from chilled water in the evaporator of the chiller. Chilled water systems provide cooling to a building by using chilled water to absorb heat from the building’s spaces. At the heart of the water chilled system, a chiller removes heat from water by means of a refrigeration cycle. As proven by a growing number of installation of evaporative chiller systems, the potential for energy saving from hybrid cooling is prominent, regardless of environmental conditions. Whether it is a cold or hot, humid climate, the operating cost benefits delivered by the evaporative chillers are substantial. We bend over backwards for our customers as you are important to us.

Sound readings were conducted after construction when the chiller was fully loaded and sound values were determined to be below the city code ordinance. In the AHUs and FCUs, the chilled water is passed through a heat exchanging coil to reduce the temperature of the coil. The chilled water that exits a chiller is called the chilled water supply . Kaltra is a customer-focused developer and supplier of reliable, energy efficient thermal management equipment and solutions. Efficiency improvements may vary depending on the number of hours the chiller runs in different cooling modes. Figures 2, 3 and 4 show the annual operating modes in Northern Europe, Southern Europe, and in the Middle East, respectively. For any of the above-mentioned locations, evaporative chillers demonstrate significantly higher efficiency values compared to those obtained with the legacy solutions. The primary difference between air and water chillers is how the unwanted heat is ejected. Air chillers us air to remove heat while water chillers use, you guessed it, water.
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.
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.
Kaltra announced the commercial launch of scroll chillers that expands an existing lineup of condenserless and water-cooled models with air-cooled version. The Severn Group delivers high-quality service to its clients from conceptual design through project punch list.

At G&D, we’re partners for life – offering modular designs for expansion & servicing every customer from start to finish. These Modular units can be utilized with any existing chilling system, helping to increase chilling capacity as you grow. Maintenance – To keep your water-cooled chiller running strong, it will need timely inspections, water purity treatments, and routine cleanings. Quiet operation – Water flows through the system relatively quietly, making a water-cooled chiller ideal for low noise environments, such as hospitals. Long-lasting – Water-cooled chillers live indoors where they’re protected from damaging elements like snow, ice, rain, and heat, which helps extend their lifespan.

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.
Discover how to cut energy costs with free cooling chillers and what aspects should be considered when selecting a free cooling system. Lightstream family of air-cooled chillers running on refrigerant R515b represents the next advance in eco-friendly cooling technology while contributing to performance improvement. Highest reliability of our chillers achieved by intelligent engineering and assured through the use of time-proven components, maximum manufacturing quality, and thorough equipment testing. This post covers three angles namely installation, maintenance and operating cost. If noise is a primary concern, then water-cooled chillers are the way to go. Noisy HVAC machines can be an annoyance, especially in buildings occupied by doctor’s offices, call centers, or other business offices. They are also popular where there isn’t ample air recirculation. Any obstructions adversely affect the performance of air-cooled chillers.
Many new energy-consuming air-cooled chillers come equipped with Internet of Things sensing components and network connectivity. Making a new purchase or replacement represents a prime opportunity to evaluate the vulnerabilities of your network. All IoT-enabled devices introduce novel exposures to potential data breaches. Building controls and heating, ventilating, and air conditioning systems are no exception. Security can almost never be networked in after the fact, and so it is important to ensure that your networked devices are secure. For more information on how to build cybersecure networks of building technologies, consult existing FEMP guidance and case studies. Products meeting FEMP-designated efficiency requirements may not be life cycle cost-effective in certain low-use applications or in locations with very low rates for electricity or natural gas. However, for most applications, purchasers will find that energy-efficient products have the lowest life cycle cost. In order to ensure the high cooling efficiency and long service life of your air-cooled chiller, we need daily maintenance and regular maintenance of all air-cooled chillers.
