Meilleures pratiques Product: Green tomorrow, comfortable today- the PURIX A25 split district cooling system
The PURIX A25 split system converts low-temperature heat sources into cooling. Substituting expensive electricity with cheap and low-quality energy sources to generate cooling is a unique opportunity to turn district heating into district cooling whilst reducing costs, environmental impact and greenhouse gas emissions. The flexible product design of the A25 split system enables integration with interior design and architecture. Dependent on the building layout and cooling demand, the A25 supports both mono- and multi split installations. It operates with pure water as a natural refrigerant, herby ensuring 0 ozone depletion potential (ODP) and global warming potential (GWP). The chiller modules are fitted with a cooling capacity of 2.5 kW each, which may be combined to systems up to a total cooling capacity of 160 kW. …

Meilleures pratiques Project: Room air-conditioner conversion project
Between 2008 and 2013, GIZ Proklima, on behalf of the German Environmental Ministry, supported the Indian company Godrej & Boyce to introduce hydrocarbon-driven (R290) split and room air conditioners to the Indian Market. Godrej & Boyce have installed a production line for R290 ACs while considering the necessary safety procedures to counter the risks arising from flammable hydrocarbon-based technology. Product certification and technician training are also a focus of the project. The new ACs have been designed according to European safety standards and have the highest energy efficiency in their class, hereby saving electricity costs and reducing indirect emissions. Each production line produces around 180,000 HCFC-free, energy efficient units annually. The direct and indirect emissions saved by these units, compared to earlier models using F-gases, amount to around 1 million tonnes of CO2 equivalent. …
Meilleures pratiques Product: India’s first R290 air conditioner
Since developing India’s first commercially available hydrocarbon (R290) air conditioner in 2012 in collaboration with GIZ and the Indian government, Godrej & Boyce have sold over 100,000 air conditioning units and now boast an annual production capacity of 180,000 units. Given the lack of national standards for natural refrigerants in India, Godrej & Boyce filled a market gap when developing the country’s first R290 air conditioning technology. The family business received an investment grant from the German Environment Ministry’s International Climate Initiative (IKI). The green technology was designed to find a balance between electricity consumption and environmental impact. With an Energy Efficiency Ratio (EER) of 3.9, the R290 ACs save up to 10% energy compared to five-star air-conditioners. Godrej & Boyce now hold a 13% market share in the five-star AC market in India, making it the third largest shareholder. Current models are restricted by a hydrocarbon charge size limit of 350 grams and 12,000-18,000 British thermal units, but Godrej & Boyce is seeking technological support from other manufacturers to achieve higher capacities. …
Membre Glaciem Cooling Technologies
Glaciem Cooling is a technology based manufacture specialising in innovative natural solutions for the commercial and industrial refrigeration sectors.

Meilleures pratiques Success 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. …
Membre GCM - German Chiller Manufacturer

Meilleures pratiques Product: 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 …
Meilleures pratiques Product: 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 …
Membre ThermoKey
Established in 1991, ThermoKey has been manufacturing heat exchangers of various types for over 25 years and is currently internationally known as the ideal partner for manufacturers of cooling units in the AC, refrigeration and cooling process fields. ThermoKey is the first European manufacturer of heat exchangers and fan units using aluminium microchannel heath exchangers. Microchannel technology allows a reduction of refrigerating fluid up to 65% and is compatible with GWP-free refrigerants, such as ammonia and propane. ThermoKey has long since introduced CO2 as a refrigerant for the whole range of evaporators to stay in line with the greenhouse gas emission reduction targets set by the regulation. Amongst the most important factors to be taken into consideration, there are the values that CO2 presents for GWP and ODP indicators, respectively equal to 1 and 0, which demonstrate its energy efficiency and sustainability from an environmental point of view. ThermoKey has already achieved these standards to offer unit coolers with stainless steel tubes for high working pressures and with copper tubes for medium pressure. …
