Once the water in the air handler system is used, it becomes warm and is sent back to the chiller. Heat is transferred away from the water using the chiller’s evaporator. Liquid refrigerant evaporates as it moves over the evaporator tube, creating a low-pressure gas. Next, the evaporated refrigerant travels to the compressor where the low-pressure gas is compressed into a high-pressure gas. While in the condenser, heat is removed from the chiller by being blown outside through fans on the side of the condenser. Because the heat is blown outside of the chiller, it is ideal to place the chiller outdoors or in a large indoor location that will not be affected by the excess heat. After the gas leaves the condenser, the refrigerant changes into a high-pressure liquid. The high-pressure liquid travels to the evaporator through the expansion valve.
This unit has the low ambient electrically controlled fan louver options for year round process cooling, yet equally as good for a comfort cooling application.

Units are 2012 and have dual compressors, hefty 5 hp process pump, insulated tank, and upgraded to the NQ series touch screen control. Water chillers remove heat by pumping water through a sealed condenser and dispersing it through the cooling tower. Water-cooled chillers are typically more efficient than air-cooled chillers. Using water evaporation to dissipate heat uses significantly less energy than blowing air across a hot surface. Additionally, water chillers tend to last longer than air-cooled chillers. Experience reliable and consistent temperature control as well as unmatched customer service when you choose Thermo Fisher Scientific. Our air-cooled chillers are durable, have user-friendly features, and are designed to remain quiet over its entire operating range.
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.

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.
A chiller equipped with a fixed speed compressor controls the temperature of the water traditionally with simple on/off of the compressor. This means that when the compressor runs, it runs at the designed load regardless of the process needs. A more advanced option is a hot gas bypass which technically keeps the chiller running but bypasses the hot gas if no cooling load is needed. This avoids the on/off of the compressor but results in a waste of energy since no cooling is required from the process. The Delta T Systems “VS Chiller” with the variable speed compressor operates effectively between 10% and 100% of its rated capacity. This means a 10 ton chiller can operate very efficiently as a 1 ton as well as up to a 10 ton chiller. This new design applies proven, variable speed “green” compressor technology from the HVAC industry to produce up to a stunning 50% energy savings over traditional hot gas bypass regulation. These energy cost savings can pay for the chiller investment in less than 3 years. In addition, utility companies may offer purchasing incentives and rebates.
Portable Air has one of the largest air-cooled chiller fleets in the industry. Our vast selection of portable, trailer-mounted air-cooled chiller units is guaranteed to increase your productivity resulting in less downtime for your project. Air-Cooled Chillers from Budzar Industries are engineered, designed and manufactured to meet your exact requirements and in addition, air-cooled chillers tend to be easy to install and require little maintenance. These conservatively calculated energy savings can be much higher because most chillers are selected based on the peak usage time of the year which means the chiller is oversized for the average usage. The condenser is a configuration of horizontal pipes through which hot refrigerant runs. 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. Multi Temp Chillers require a pump to move water through the heat exchanger at all times.
In addition, the cooling capacity is also a factor that reflects the performance of an air-cooled chiller. Afterward, the vapor is released into the air-cooled type condenser. High efficiency, TopChiller air-cooled chiller takes a balanced approach to lower energy costs. We deliver high full-load performance to reduce demand charges and high part-load performance to reduce kWh rate charges. Understanding future air-cooled chiller performance requirements are critical to selecting the best air-cooled chiller for the project. Air-cooled chiller designed and manufactured by TopChiller has 3 or 4 refrigerant circuits for air chiller models from AC-25AF to AC-60AF depending on chiller refrigeration capacity.
The air cooled screw chillers supplied by TopChiller® are a suitable water cooling partner for plasma cutting machines. In the printing industry, air cooled screw chillers are used to dissipate the heat created by the heated printing rollers in the process of friction.
