Trane air-cooled chillers are the right choice for tight temperature control in virtually any application. The refrigerant first leaves the compressor as a high pressure, high temperature, superheated vapour and then enters the condenser. Evaporator – This is where the chilled water is produced and the heat from the warm return “chilled water” is extracted, to be sent to the condenser. The condenser – a bundle of horizontal pipes which contain the hot refrigerant, these are surrounded by a number of thin sheets of metal in the vertical axis. These help distribute heat away from the tubes and into the air which is blown across the tubes and thin sheets of metal. But, small chillers have historically been unable to provide a strong ROI due to high equipment costs and unrealized efficiency potential. The Arctic Chiller Group is proud to offer a training and certification course to provide technicians with the necessary skills to maintain and troubleshoot Arctic chiller systems. The Arctic Chiller Group is the global leader in manufacturing chiller systems. We design cost-efficient leading-edge chillers and applied solutions to meet individual customer needs. For over thirty years, Cold Shot Chillers has been producing the very best industrial chillers.
They have commonly been used for medium and large installations that have a sufficient water supply. Water-cooled chillers can produce more constant performance for commercial and industrial air conditioning because of the relative independence to fluctuations of the ambient temperature. Water-cooled chillers range in size from small 20-ton capacity models to several thousand-ton models that cool the world’s largest facilities such as airports, shopping malls and other facilities. A chiller uses a vapor compression mechanical refrigeration system that connects to the process water system through a device called an evaporator. Refrigerant circulates through an evaporator, compressor, condenser and expansion device of a chiller. A thermodynamic process occurs in each of above components of a chiller. The evaporator functions as a heat exchanger such that heat captured by the process coolant flow transfers to the refrigerant. As the heat-transfer takes place, the refrigerant evaporates, changing from a low-pressure liquid into vapor, while the temperature of the process coolant reduces. An air-cooled chiller works by absorbing the heat from processed water.

Now we come to the topic of air cooled chillers, Air-cooled chillers are the most popular compared to other types of chillers because of easy operation and low maintenance costs. This protection makes sure all air cooled chillers have an outstanding cooling performance and long service life. An air-cooled chiller made by TopChiller consists of a scroll compressor, air-cooled type condenser, built-in water pump, and water tank to make a complete compressed refrigeration and water cooling system. Chilled water is used to cool and dehumidify air in mid- to large-size commercial, industrial, and institutional 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.
Condenser coils use a V configuration to optimize heat rejection and footprint. Most Multistack modular systems comply with ASHRAE 15 and CSA B52 standards, which means you can do without auxiliary ventilation, monitoring and SCBA equipment. Not to mention an operational advantage when it comes to obtaining LEED certification. If your current chiller shows signs of aging and you are considering replacement, we are confident that you will find using our screw chillers will help you a lot with production efficiency and cost reduction. 8.2.1Adjust the cooling system flow valve carefully , to make system water flow be 90% water flow required by the nameplate on the unit. 1)Air-cooled condenser of this screw chiller with upside-down M shape layout to improve space using ratio, heat exchange area of air-cooled condenser and to reduce the unit overall size. 2)High automatic management with complete features to realize unit start-up and shut down, timing control, water pump control, malfunction alarm and self-diagnosis features. 2)A brand condensing axial fan is used in the screw chiller unit. Air-cooled screw chiller having integrity structure saves the cooling tower and reduces construction investment. Therefore, the initial pouring temperature of the concrete should be low, reaching the limit temperature of the building design unit, thus ensuring the quality of the project.
Motivair’s Free-Cooling Chillers are designed to provide the owner with optimal, year-round performance in varying ambient temperatures. There is a lot of heat generated by friction through the printing rollers and as ink is dried in ovens. To keep the rollers in good condition and freshly printed paper in good condition chillers are used. They remove the heat from the process and keeps the parts and paper in good condition despite the high heat conditions. Air cooled chillers can suffer from damage, blockages and re-circulation issues. Low Ambient Motormaster Variable Frequency Drive option for fan. Allows process cooling to continue in lower outside winter temperatures. Unit was run and tested here at our Massachusetts facility prior to shipping. It has switch, piping and plumbing, and solenoid valves to direct flow as needed to a “free cooler” / liquid cooler in winter months if the temperatures support it, so you don’t use your refrigeration energy. That module is not included, and can be obtained from various suppliers like KRACK or similar if you are in a cold environment and interested in that feature.
If you pair one of these systems with the wrong application, it likely won’t perform properly or as efficiently as you want it to.

When making food for human consumption, keeping your food products free from bacteria or other contaminants that could poison those who consume it is the number-one priority. A few people getting sick could ruin a food processing business, let alone if something worse happens. One of the best ways to prevent food from going bad is to control the temperature, as most bacteria cannot survive in extremely low temperatures. Water contamination can ruin a plastic product and is a very common problem. Our air-cooled screw chiller can save you dramatically by reducing product loss. Next, we’ll talk about a couple of different chilled water system configurations. Cooler shall be shell and tube design with refrigerant totally enclosed in shell and water in tubes. Exterior casing shall be manufacturer’s standard equipment casing coated with corrosion resistant exterior finish and with removable doors or panels for service and inspection. Wiring diagrams shall differentiate between manufacturer installed and field installed wiring.
Recording operating conditions such as flow rates, pressures, fluid levels, and temperatures helps build a useful record of your system. While it was standard to do bi-monthly checks today’s continuous monitoring technology allows you to keep accurate daily logs that will help you narrow down maintenance issues before there’s a bigger problem. Heat Recovery Chillers from Motivair are designed to optimize overall chiller efficiency by simultaneously producing chilled water and hot water. Chillers used in plastic fabrication typically take on one or both of two roles, cooling the plastic products and cooling the machinery used to make them. The chiller units are also used to keep the barrel of the extruder, and hydraulics of the molding machine cool. This not only saves on energy but it also helps extend the life of the plastic fabrication equipment. Instead of utilizing a mechanical compressor the absorption chillers use a heat source to be the driving force behind the refrigeration cycle. These chillers typically use two liquids, one to cool and one to absorb.

It is noteworthy that evaporative system can be used to retrofit existing chilled water plants, without the need to redesign the entire cooling infrastructure.
For instance, during the cool night hours, it may be more efficient to raise the chilled water supply temperature setpoint of the chiller. Raising the chilled water supply temperature setpoint will allow the chiller to not work as hard. When you consider that chillers are often one of the largest consumers of energy inside a building, their performance can have a huge impact on operational costs. For this reason, the efficiency of a chiller plant is often closely monitored for potential improvement. As some of the condenser water evaporates, heat is removed from the condenser water, and the cool condenser water flows back to the chiller. Air-cooled chillers are almost always located outside of a building and remove heat from the chilled water by exhausting the heat directly to the surrounding air. When a chiller is producing chilled water, the heat that is removed from the chilled water must be rejected somewhere – usually outside of the building. The chiller system is the facilitator of heat transfer between the inside of a building and outside of a building.
