Industrial, Air Cooled & Water Cooled Chillers

Only sporadic periodic cleaning of air condenser coils might be needed if the air-cooled system is operating in a dirty environment in order to avoid the fouling. If fouling is accumulated, your system will develop higher operating discharge pressure, which may increase power consumption by the chiller. Water-cooled systems also have operation and maintenance issues; although it mostly depends on the quality of water used and surrounding conditions. Ozone, being a powerful oxidizer, can also help reduce this biological problem. When water evaporates from a cooling tower, it leaves behind all its solid matter. The only way to deal with this problem is to add water to the tower periodically to compensate for the lost water in a process which is called blow down. It prevents proliferation of dissolved solids, which may cause a bigger problem in the form of scale and rust formation. Generally, maintenance of this system is much more demanding than for an air-cooled system.

4)In the area where the ambient temperature is below -10℃, It is not suitable to use a heat pump type chiller because of the low heating efficiency of the heat pump. The user has to pay attention to handling the air cooled screw to avoid damage caused by installation and transportation. 2)Air cooled screw chiller with pen type structure is a convenience for maintenance and reduces service space. High-pressure, over-heated refrigerant gasify, and radiates heat energy into ambient, then refrigerant is condensed into the liquid status and passes by the expansion valve. Both air-cooled screw chiller and water-cooled screw chiller are composed of a compressor, an evaporator, a condenser, and an expansion valve. After the oil leaves the compressor, it will circulate throughout cooling components and hinder heat transfer, and even reduce the capacity of the evaporator and condenser. Various refrigerants such as R134a, R407c, R410a, and R404a are all available depending on the screw chiller working condition, application requirements and ambient temperature. Each screw compressor with 4 steps of energy control 25%-50%-75%-100% to make sure the whole screw chiller is stable and guarantee high refrigeration performance.

Here we have a 2003, 60 ton Carrier HL series chiller which has never been used or connected to power. This is a split system, meaning the chiller is indoors and the remote condenser is mounted outdoors, with field installed refrigerant lines connecting the two. You will get the 0 hours chiller, and a BRAND NEW and compatible 2013, 60 ton dual circuit condenser. 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 . Arrived at KIG in January 2016 was this substantial Trane Chilled Water Air Handler System. This was used in conjunction with a 30 ton Chiller in a climate cooling environment.

The difference between air cooled and water cooled chillers is that air chillers use ambient air as the condensing source and a fan that moves the air over the coil. Water chillers on the other hand use water as the condensing source and a pump that circulates water through the condenser out to the cooling tower that releases it into the atmosphere. This GCI Icewagon 13 ton Air Cooled Chiller arrived into KIG’s shop in May 2014. We have cleaned and painted the unit, and done any repairs and checks as needed. It has been run and tested and was offered with a money back guarantee. It is 460 Volt, has a Danfoss/Maneurop 13 hp sealed reciprocating compressor which we have had great luck with on chillers in the past. Chiller has hot gas bypass option so as to keep compressor running a bit longer when there is a lower load on the system, which reduces the amounts of starts and stops on the system. This unit does not have an on-board reservoir tank, but could easily integrate with your storage/buffer tank as the inlet to the chiller goes right to the suction side of pump.

The absorbent liquid is usually ammonia or lithium bromide, and the coolant is usually water. Inside the stationary housing it contains to mating helically grooved rotors. Direct volume reduction is achieved when the helical rotors rotate. The capacity of a rotary screw compressor varies between 20 and 450 tons and is controlled by a sliding inlet valve or variable speed drive. Water cooled chillers can handle larger loads, for their floor space, compared to air cooled. Absorption chillers should only be used where there is an abundance of high quality waste heat or cheap heat. They are often found in hospitals and buildings with heated swimming pools. Sometimes they are used during times of day when electricity prices peak. Nice late Model 2007 Trane larger Air Cooled Chiller, 250 ton size, 460 volt. Unit has been vacuum and leak tested, and new charge put back into unit.

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.

Motivair Cooling Solutions enables industry leaders to push the boundaries of what’s possible by leveraging over 30 years of insights and innovations creating dependable mission critical cooling systems.

The refrigerant then passes through an expansion valve, where it rapidly cools and goes through the evaporator, where it cools the chilled water. The chiller controller manages the switching between operating modes according to the ambient temperature and humidity, thus realizing the most energy efficient cooling regime. Water-cooled chillers have greater complexity due to the connection to a cooling tower system. Water-cooled chillers typically reside indoors in an environment protected from the elements. Water-cooled chillers typically represent the only option for larger installations. The additional cooling tower system will require additional installation expense and maintenance as compared to air-cooled chillers. The refrigerant then flows to a compressor, which performs multiple functions. First, it removes refrigerant from the evaporator and ensures that the pressure in the evaporator remains low enough to absorb heat at the correct rate. Second, it raises the pressure in outgoing refrigerant vapor to ensure that its temperature remains high enough to release heat when it reaches the condenser.

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.

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.
