Best practiceSuccess story: Parilla Potato Cold Storage Facility
In 2012/2013, Glaciem Cooling Technologies in collaboration with the University SA Barbara Hardy Institute and Alltech Refrigeration launched the Parilla Potato Project. Parilla Potatoes is a large, refrigerated storage facility located in South Australia. The basis for the design of the Parilla Potato Project is a secondary refrigeration system that uses a critically charged ammonia chiller as the primary refrigerant and Dynalene HC30 as a secondary refrigerant. Moreover, the design also includes the use of a Thermal Storage System using Phase Change Material (PCM). The PCM is cooled by the primary ammonia plant overnight using off peak electricity, and the Dynalene uses the thermal storage of the PCM to provide refrigeration during peak operating hours. In 2014, the system won the AIRAH Best HVAC&R Retrofit/Upgrade award. …
MemberGCM - German Chiller Manufacturer
Manufacturer of reliable and flexible highly efficient chiller solutions The German Chiller Manufacturer (GCM) designs and develops highly energy efficient chillers using natural refrigerants. Due to the EU Regulation No. 517/2014 and the phase out of F-gases within the EU, GCM focusses on manufacturing systems using natural refrigerants– mainly R717 (ammonia). GCM stands for tailor made high quality systems and flexible design options to suit their clients’ specific needs. …
Best practiceProduct: Air-cooled chiller
The GA-2 KO-1-N-200 is a highly efficient air-cooled chiller that produces cold water for industrial processes using the natural refrigerant ammonia (R717). By using high quality components and a natural refrigerant, the chiller achieves an energy efficiency ratio (EER) of 4.94. This in turn reduces the operating costs and increases the machine’s lifetime. Moreover, ammonia is characterized by a global warming potential (GWP) of 0, such that it is not affected by the F-Gas regulation and its phase down schedule. By choosing a system that runs on a natural refrigerant without global warming potential (GWP), the consumer is actively contributing to environmentally friendly cooling. Refrigerant: R717 Cooling capacity: 200 kW Energy efficiency rating: EER 4,94 …
Best practiceProduct: 3-in-1 chiller
The chiller GS-1-KO-1-N-102-SP designed by the German Chiller Manufacturer (GCM) uses ammonia (R717) and combines three independently operating machines in one unit. The operator therefore profits from full redundancy; if one of the three machines fails, the remaining two continue to cool. The three machines comprising the GS-1-KO-1-N-102-SP are connected by a master control system, but each machine has its own control center for emergencies. By choosing a system that runs on a natural refrigerant without global warming potential (GWP), the consumer is actively contributing to environmentally friendly cooling. The use of R717 in combination with qualitatively high components ensures that the chiller system has an energy efficiency rating (EER) of 5.56. The investment into the environmentally friendly and economic cooling system was supported with a 20% grant of the total production costs by the Federal Office for Economic Affairs and Export Control (BAFA). Furthermore, the GCM grants a five-year warranty for the cooling system with a maintenance contract upon purchase. Refrigerant: R717 Cooling capacity: 444 kW Energy efficiency rating: EER 5,56 …
Best practiceSuccess story: All-in-one heating, cooling and air conditioning in retail giant Kaufland
Frigo-Consulting has installed an integral CO2 system in retail giant Kaufland’s new large-scale store in the suburbs of Germany, Berlin. The integral CO2 system is a lighthouse project, as it cools, heats and ventilates without needing additional energy. It uses waste heat produced during refrigeration to heat and ventilate the entire Kaufland building. 25-30% less energy is consumed compared to traditional installations, as well as a reduction of the CO2 footprint by 35-40%. The system can adapt to a range of operation needs, e.g. summer vs. winter temperature, working days vs. weekends, etc. Frigo-Consulting took the lead in the project engineering and provided a customized future oriented concept. Since the first installation in 2014, Frigo-Consulting has successfully engineered and commissioned several integral systems. …
Best practiceSuccess story: The Fridge Factory conversion project
With the support of GIZ Proklima, in 2008 the Fridge Factory was the first refrigeration manufacturer in the sub-Saharan region to convert its production line to natural refrigerant-based technologies. During the 3-year project, the Fridge Factory converted its entire domestic and commercial production line to operate with hydrocarbon refrigerants, with an annual production of approx. 60,000 appliances. Every sold unit replaces the use of fluorinated refrigerants, hereby avoiding an equivalent of 250 kg of CO2 of direct emissions during the lifetime of a unit. Moreover, the new appliances save more than 20% energy consumption compared to conventional units, hereby reducing electricity costs. The conversion to modern technologies strengthens the Fridge Factory’s market position against environmentally-damaging imports. Moreover, qualifying the engineering and technical staff to work with the new technology helps secure and maintain around 500 jobs. …
