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.

In 2013, the Pennsylvania State Employees Credit Union (PSECU) opened its new facility operating with an absorption chiller to provide 300 tons chilled water to the data centre. The absorption chiller is also able to cool excess heat recovered from the micro-turbines, to provide chilled water for air conditioning, or hot water when required. During the winter months, nearly 100% of the building is powered by the cogeneration system and in summer nearly 60% of the building is powered by the system.

The whole project saves Neste Oil roughly 42,000 Euros each year in energy costs.

In Beringen, Belgium, Neste Oil established a refinery for poly-alpha-olefins (a lubricant made from synthetic oils) with a daily production capacity of 270 tons of oil. Axima Refrigeration replaced a R22 refrigeration unit with an ammonia refrigeration unit. In the first phase of the conversion, Axima Refrigeration installed an ‘economizer’ to save energy, fitting an air cooled condenser and an evaporative condenser in a parallel circuit controlled by an intelligent system. In the second phase, Axima replaced the R22 refrigeration unit with a ammonia unit equipped with a frequency regulator and a system to reduce the condensation temperature. The whole project saves Neste Oil roughly 42,000 Euros each year in energy costs.

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.

Energy Efficency

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.
