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 . The condenser is a configuration of horizontal pipes through which hot refrigerant runs. Air is moved across the condenser to dissipate unwanted heat. The compressor provides the driving force for moving the refrigerant around the system. Three of them use positive displacement to create pressure, and the fourth creates pressure with centrifugal force.
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. Much of the noise reduction is in frequencies where noise is most annoying, which makes AquaSnap chillers ideal for sound-sensitive environments. We are proud to provide exceptional walk-ins and blast chillers.

Choose the portable air-cooled chillers from Shini USA to receive a reliable, efficient system to incorporate into your operations.
The compressor is then tasked with pumping the refrigerant vapor to the condenser, which increases temperature and pressure. The refrigerant condenses when it’s in the condenser tubes, releasing its internal heat to the air or cooling water. The high-pressure liquid then moves through the expansion device and into the evaporator; in the process the refrigerant pressure is reduced along with the temperature. To complete the continuous cycle, the refrigerant flows back over the chilled water coils and absorbs more heat. An air-cooled chiller works by absorbing the heat from processed water.
Chillers use metal tubes to transfer water between the chiller and the climate-controlled space. The simple presence of oxygen in water can cause corrosion, but if the water and pipes are treated properly, this can significantly reduce the risk. However, if the water treatment is inadequate, sediment, minerals, and bacteria can enter the system. If there is a buildup of sediment or bacteria that causes oxygenation levels to differentiate, the metals can begin to corrode. In addition, any point where two different metals are used can be at risk for corrosion due to their different electrochemical properties. No matter how the corrosion occurs, it can cause leaks that will damage the chiller, reduce its efficiency, and possibly damage the area surrounding the chiller.
An Air-Cooled Chiller is basically a refrigeration system that works by transferring the heat energy from fluids. Air-Cooled Chillers are used in a wide variety of settings and industries including medical, pharmaceutical, chemical, biotechnology, semiconductor, food, construction, plastic, and many others. To protect the chiller from inclement weather, the outdoor chiller may be installed in a pre-fabricated, insulated walk-in enclosure. Condenser and water piping to be heat traced for freeze protection. The electrical systems within a chiller are carefully designed and as complex as the rest of the machine.
These acknowledged inefficiencies cost companies and building facilities billions of dollars annually. Cooling Power offers air cooled chillers to meet a wide variety of needs and demands. Contact us today for a free quote or to help determine the best option for you. Portable air-cooled chillers can also be used for large events or emergency situations. The refrigerant is the only fluid which moves around each of the components of the chiller. It changes its pressure, temperature, enthalpy and entroy as it moves around the machine and transports the unwanted heat away from the evaporator chilled water.
Evaporative 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. The water is then recirculated to the chiller to be recooled. 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. Commonly, chillers receive water at 12°C , and cool it to 7°C .

Centrifugal chillers’ efficiency is calculated differently from absorption chillers’ efficiency, for example. However, when you calculate each type’s efficiency and compare them, absorption chillers are more efficient overall. A fully weather-proof enclosure is used to protect the compressor and the NEMA 4 control panel enclosure. These industrial process cooling systems come pre-piped and prewired and require a minimum of installation effort. These industrial refrigeration units are used in conjunction with theBerg Pump Tank Assembly to create a Central Chilled Water System.
Arrived last week of January 2016 to KIG’s facility was this nice 2009 McQuay 50 ton Air Cooled Chiller. Made in 2010, this is a highly engineered nice outdoor rated chiller unit for process or comfort cooling and with low ambient capability for year round operation in colder climates . This unit underwent a refurbishment, including complete repainting of the chiller.

The refrigerant vapor is drawn out of the evaporator by the compressor. The compressor then “pumps” the refrigerant vapor to the condenser raising its pressure and temperature. The refrigerant condenses on or in the condenser tubes, giving up its heat to the cooling water . The high pressure liquid refrigerant from the condenser then passes through the expansion device that reduces the refrigerant pressure and temperature as it enters the evaporator. The refrigerant again flows over the chilled water coils absorbing more heat and completing the cycle. Air cooled chillers are located externally to a facility and have condenser coils cooled by fan-driven air.
