This unit has its own process pump, an internal reservoir, and a brazed/plate heat exchanger. eNoise Control has been involved with several outdoor HVAC chiller noise applications. Air cooled chillers with rotary screw compressors present the largest challenge for adequate noise control because of the multiple sound sources and the tonal quality of the noise. Below are some actual case histories of Unger’s involvement with outdoor environmental noise control dealing with air cooled chillers. Water-cooled chillers feature a water-cooled condenser connected with a cooling tower.
Since the wet-bulb temperature is always lower than the dry-bulb temperature, the refrigerant condensing temperature in a water-cooled chiller can often operate significantly lower than an air-cooled chiller. With 20 years of experience in air cooled screw chiller manufacturing, TopChiller is willing to provide all technical support to clients worldwide. Even if the customized air cooled screw chiller based on your specific requirements, we also have all ready screw chiller spare parts. As there are many industries and each industry may require air cooled screw chillers of specific sizes and cooling capacities.

This can only be done onsite and made specifically for your business. This can force the chiller to be relatively small, which could preclude having a pump and reservoir in the chiller. You can also be a distillery that needs to cool down the water for your chiller between distilling processes, or need to pump more water than usual through a small chiller during a peak season. In these instances, a separate remote pump and reservoir will be necessary. This pump and reservoir combination will need a stand to contain and protect it while it works. Our mounted steam and hot water boilers combine versatile design with low maintenance. LG Air-cooled Inverter Scroll Chiller is equipped with twin inverter compressors that are applied in VRF products, allowing a wider operation range.

In the meantime, TopChiller® also provides a comprehensive range of services for pre-sales questions and after-sales issues, covering everything from product inquiries to maintenance support. TopChiller® Air Cooled Screw Chillers are aimed to optimize the energy efficiency of the target devices. If the heat exchanger of the evaporator or pipes freezes to broke, it will result in serious leaking. Pre-heat time for lubrication of the compressor according to weather and ambient environment, but preheat time cannot be less than 12 hours. After a long period of running, the inside of the pipe in the dry-type evaporator is accumulated calcium oxide or other mine substance.
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.
The 300 lbs of R22 was removed and recovered prior to disconnecting, so the new owner had to re-charge. Arrived at KIG in August 2016 was this nice 15 ton Drake Air Cooled Chiller. This 460 volt unit has DUAL compressor, and also a 2 pump system with evaporator pump and process pump.

Unit was run and tested at KIG and sold with a money back guarantee. Acquired by KIG in March 2015 was this nice 14 ton York YCAL series Air Cooled Chiller. We refurbish/test/sell about 100 chillers annually from our Clinton MA facility, and this unit was run and tested here prior to shipment, and sold with a money back guarantee of functionality. The unit has DUAL 7 hp Scroll compressors, and it has the factory “low ambient” option to allow this chiller to be used year round for process cooling in both warm and cold climates .
The heat molecules inside the refrigerant are able to spread out when the refrigerant leaves the orifice of the expansion valve. Then the condenser is used to lower the temperature of the refrigerant below the saturated condensing temperature, which enhances the refrigeration effect and improves system capacity eventually. When the water has reached a particular temperature, it will send the heat back to the refrigerant in the evaporator and get evaporated. The cooling process begins with the evaporator, whose tubes contain some kind of liquid refrigerant. A double screw compressor integrated with an oil separator maximizes the efficiency of the air-cooled screw chiller. Please contact TopChiller sales to get the best water cooling solution of your air-cooled screw chiller.

Don’t short-circuit the protected air cooled screw chiller, otherwise, It will cause serious problems. The refrigerant filled by weight may be affected by ambient temperature. In this case, turn off the fluorine container valve temperately temporarily, let cooling water circulating in the evaporator and startup the unit, at the same time, short-circuit low-pressure controller temporarily.
Cold Shot Chillers® has a variety of configurations to best fit your application. Whether you need a stationary air cooled chiller, portable air cooled chiller or central air cooled chiller, Cold Shot Chillers® has the solution to all your air cooled chiller needs. Gas is compressed inside these types of chillers with pistons, not unlike a car engine. There are multiple pistons that continue to compress the gas to heat it. The difference is that the hot gas is used inside the system, not simply exhausted out of a tailpipe. The demand is matched by the adjustable intake and exhaust valves that can be opened to allow the piston to simply idle. Idling the piston when demand for chilled water helps manage capacity. This system is very flexible and can cope with the specific demands from load on the system. It is also possible to manage the capacity to match the demand with a hot gas bypass, but it is not considered to be as efficient.
