Industrial Air Conditioning

Air conditioning is used in industrial applications to ensure correct operation of equipment that requires specific environmental conditions or to dispose of heat created by some industrial processes like welding. Data centres are core consumers of industrial cooling.

Lundbeck Pharmaceuticals, a Danish drug manufacturer, needed to expand its production capacity in Seal Sands, England. The production process requires adhering to precisely specified temperature gradients, with temperatures ranging from -121 to 500°F (-85 to 260°C). Lundbeck required a cooling solution that was efficient, reliable and environmentally friendly. Star Refrigeration produced two factory-built, skid-mounted air-cooled ammonia systems that supplied each loop with cooling energy. Factory packaging significantly reduced onsite assembly and facilitated the production start-up. The low-temperature cycle at 41°F (5°C) cools 400 m3/hr of the coolant Therminol D12 from Solutia with a refrigeration output of 1.4 MW. The ultra-low temperature cycle chills 50 m3/hr of Therminol D12 to -13°F (-25°C) with an output of 220 kW. Both cycles use soundproof rotary screw compressors and high-performance fully welded plate and shell evaporators, which assist in the design of a system with a small refrigerant charge. The refrigeration systems have tanks for storing the secondary refrigerant, which helps to bridge downtimes and facilitate maintenance work. Star Refrigeration equipped the plant with modern controls, including ammonia detectors. Thanks to the modular design, the operator can easily and inexpensively expand the installation at any time.

The world’s deepest metal mine, Kidd Mine, is ventilated by an ammonia-based cooling system that indirectly cools water that is pumped through a series of compressors, condensers and evaporators. The system is capable of cooling air to a temperature of under 28°C (82.4°F) while delivering energy systems for the operators. The entire refrigeration plant and Bulk Air Cooler (BAC) are located on the surface of the mine. The refrigeration plant was supplied by Australia’s AustCold. The compressor set for the plant is a 1750 HP Howden screw compressor with matching plate-and-frame heat-exchangers for the condenser and evaporator. The plant uses ammonia as the refrigerant. The plant chills the water to be delivered to the BAC. In turn, the returning water from the BAC is circulated back to the plant to, once again, be chilled. This effectively forms a closed-loop system, although some make-up water is required from time to time to replenish that which is lost to evaporation.

The Bayer Chemicals Group commissioned York to build an ammonia-based refrigeration system at its primary plant in Leverkusen, Germany. This facility is one of the largest production facilities in the world, spanning roughly 600 buildings on more than one square mile, Bayer manufactures pharmaceuticals, dyes, rubber, polyurethanes and organic and inorganic products.The company chose ammonia because it is an efficient, economical and environmentally friendly refrigerant. The job was part of Bayer’s extension of the remote cooling system. The heat generated by all production-related processes is dissipated through a remote refrigeration plant with several refrigeration centers. Three different temperature levels are available for this process: 23, -4 and -49°F (-5, -20 and -45°C). Decentralized cascade chillers, also hooked up to the main supply, provide temperatures of -49°F and below. Bayer uses the remote refrigeration plant, which comprises several large units, to economically generate cooling energy and ensure a steady supply.In the York engineered refrigeration plant, two rotary screw compressor units provide cooling energy. The refrigerant, ammonia, is liquefied in condensers that are supplied with cooling water. The refrigerant is then fed into the liquid line through a sub-cooler and part-time jetting pumps as needed to supply the process loads. The overheated ammonia gas returned by the network is cooled in a suction separator and is then returned to the suction side of the compressor. The plant’s refrigeration output exceeds 5 MW.

To provide a controlled climate for this hardware, the manufacturer, Star Refrigeration, designed and built a low-energy-consumption CO2 refrigeration system in 2006 to generate a total output of 300 kW. The carbon dioxide is recondensed with water at 6C via an indirect chilling cycle. The cooling is handled by ventilator units on the back of the server cabinets, where the carbon dioxide evaporates at 14C and absorbs the heat siphoned off by the fans. CO2 is reportedly well suited for IT climate control as it does not conduct electricity, helping to increase safety.

The Vicot solar ammonia-water air conditioning was a joint development between the Chinese company Vicot and Rocky Research of the United States. The system uses 8kg of ammonia in one 21kW unit. The modular assembly can connect up to 8 units under one control.The Vicot solar air conditioning system consists of three components, i.e. the solar collector, the air conditioner, and the thermal energy storage system. The solar trough collector is designed to be capable of reaching up to 300°C. A heat transer loop transports thermal energy to the absorption air conditioner. The absorption chilller converts the high temperature heat into building cooling and heating via a hydronic chilled water system. The system facilitates 24-hour solar power driven air conditioning for cooling, heating, and domestic hot water with built-in thermal energy storage. Thermal energy storage is provided via the phase change heat storage system and/or an ice storage system allowing continuous chiller and heater operation throughout the night and during cloudy days.The company estimates 3-5 years payback time on capital costs, depending on local irradiance conditions.

Up to 80% energy savings compared to conventional technology

The modular design of the system makes it possible to operate only those components needed to achieve the required temperature lift by interconnecting the cooling units as a function of the internal heat load and outside temperature. The transitions are continious and range from two-stage, full-load capacity to single-stage operation and even a pure free cooling mode. But, unlike other conventional refrigeration systems with “free cooling” modes, eChiller’s internal passive cooling kicks in even when outside temperatures are only marginally lower than the cooling water or brine intake temperature. Feasible chilled water temperatures start at 10 °C. As a result of the system design, cold water temperatures of 22 °C and above, which conventional cooling systems cannot work with, are especially efficient. Here, the eChiller 2-35 achieves a cooling capacity of 35 kW.
