Quarterly inspection helps your chillers, HVAC system, and cooling towers last longer and run more efficiently. If your compressor uses oil make sure you send a sample of it for inspection at a laboratory once per year. Due to the hermetically sealed nature of a close refrigerant system the compressor oil should only be changed if the lab deems it necessary. If there’s excessive moisture it can point to there being a problem with purging the system effectively. If the oil is changed ensure the filters are tested and replaced when there are pressure drops. In the case your system uses magnetic bearings and is frictionless your system will not have compressor oil. Industrial Process Chillers from Motivair offer a compact footprint with a standard primary pump, storage tank and powerful microprocessor controller. Motivair’s Air-Cooled Scroll Chillers are designed to provide the owner with optimal, year-round performance in varying ambient temperatures.
It has two Copeland scroll compressors, each pre-packaged in an Emerson condenser module with side air discharge, and situated one over the other. The dual heat exchangers are coil in tube, or coax type, and this is a true dual circuit machine. The R404a refrigerant offers less “de-rating” for low temp applications as compared to R410a. The controls are a super simple Ranco dual stage controller, and simple fan switching for low ambient. The tank is a separate module, in enclosure and insulated, about 300 gallons. Arrived at KIG in July 2015 was this pristine AEC-Sterling-Sterlco 7.5 ton Air Cooled Glycol Chiller. Please take into account de-rating of the actual cooling capacity (approx 25% to 35%) when cooling at lower temperatures like this. Unit was run, tested, and checked out thoroughly in our MA shop prior to shipping. Acquired by KIG in March 2015 was this nice 15 ton Carrier Aquasnap Air Cooled Chiller.
Also based on cooling methods, chillers can be divided into air cooled chillers and water cooled chillers based on the cooling method. Each air cooled chiller manufactured from TopChiller has a built-in water tank and water pump, some of the charged refrigerant R407c, R410a and R134a are also available for high ambient temperature. Compa-Chill Central Air Cooled Whaley Chillers are used in industrial and commercial applications from central chilling of processes to HVAC. COMPA-CHILL has become the number one chilling equipment of choice, which incorporates new high efficiency Scroll compressors and stainless steel plate evaporators. Central chillers are designed to cool multiple processes with one chiller system. The multi-circuit design is used on critical process loads that absolutely cannot be down. WPI will provide complete water system design and plant process survey to determine cooling loads.
All told, air cooled chillers can provide simple and effective solutions for many process cooling needs. Air cooled chillers are among the most commonly used refrigeration systems for commercial and industrial facilities. They work by absorbing heat from process water and then transferring this heat, meaning that they should be used in areas where heat discharge is not a serious issue. Like water cooled chillers, they have a compressor, condenser, evaporator, and expansion valve that work to chill water and absorb heat. As opposed to water cooled chillers, they use air to fuel condenser cooling. Most if not all outdoor applications for chillers will use air cooled chillers as excess heat is released into the ambient air.
To complete the continuous cycle, the refrigerant flows back over the chilled water coils and absorbs more heat. Water and air are the main heat rejection mediums for air conditioning systems. When water is plentiful and inexpensive, a water-cooled system, often involving a cooling tower, becomes the most efficient option. If water is unavailable or expensive, air-cooled systems become preferable. ARANER has a wide range of heat rejection systems for all applications. The solutions offer state-of-the-art technology that suits all environments and other requirements. Water-cooled chillers use water to surround the refrigerant pipes and draw in the heat . The water is then pumped into a cooling tower to release the heat.
We have included a photo taken pointing inside the chiller barrel from the process piping. If you know about chillers, you see the condition of the copper tubes are new, as they should look with virtually zero production hours. Arrived at KIG in May 2016 was this 2007 Carrier Aquasnap 80 ton Air Cooled Chiller. Low ambient VFD drive for year round cooling even in colder climates. About 7500 hrs total run time, and 3500 hr or less on each of the 4 compressors. Unit has a 5 hop process pump, and 2 hp circulation pump, and a 120 gallon reservoir tank with baffle. Unit has desireable Hydronic Package Option, which means there is a process pump, and heated storage tanks below unit. The process pump has been rebuilt, and new temperature sensor installed.
Air-cooled water chillers are refrigeration systems that cool fluids to support industrial processes. A case study on the chilled water production site to provide efficient cooling of 120 cubic meters of glycol solution per hour for milk processing plant. Variable-speed chillers to deliver 10% better COP to air conditioning and medium-temperature process cooling applications. Selection criteria of these systems depend on the respective advantages and disadvantages in regards to a district cooling plant. Choose a water-cooled system if water supply is plentiful, ambient air is free of particles and relative humidity is low during the hot season. An air-cooled system is suitable if water supply is inadequate, water supply is unclean and average relative humidity is high during the hot season.
When you use this system, the cooling tower that it’s combined with will send water to properly cool and condense the primary coolant that you’re using. Any unwanted heat from the chiller will be sent into the cooling tower before being dispersed into the outside air. There are two notable types of industrial chillers that you can select for your cooling needs, which include a water-cooled chiller and an air-cooled chiller. A water-cooled chiller is a type of chiller that’s usually combined with a cooling tower for large-capacity applications like water-jet cutting and food processing. With large-capacity applications, it’s possible that an air-cooled chiller will generate too much heat. Since a water-cooled chiller is typically combined with a cooling tower, it allows for the maximum amount of efficiency that’s possible with these systems.

The liquid status refrigerant goes into the compressor from the evaporator. 6.9.2If the temperature of the outdoor is below 0℃, the water in the evaporator should be discharged completely. Refrigerant should be sucked into the condenser and then close the inlet gas valve and outlet liquid valves. All maintenance operations must be done by experienced personnel, qualified to work with conditioning and cooling systems.
Air-cooled machines are directly cooled by ambient air being mechanically circulated directly through the machine’s condenser coil to expel heat to the atmosphere. 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. Water cooled and air cooled chillers work in a rather similar manner. They both have an evaporator, compressor, condenser and an expansion valve. The main difference is that one uses air to fuel condenser cooling and the other uses water. These benefits aside, the fantastic customisation benefits on offer open customers to options such as low water temperature configurations to -10 degrees, water accumulation tanks, and total heat recovery. If you’re seeking coolers that last, then there’s certainly no need to look further than the Aries Tech 2. A chiller is a relatively basic system wherein heat is removed directly from the coolant before it’s transferred over to the surrounding air, which is essential for the cooling process.
