Meilleures pratiques SABROE SABlight air-cooled chiller
Johnson Control’s SABROE SABlight air-cooled chiller uses propane as a refrigerant, providing an environmentally friendly and economic alternative to air-cooled chillers using synthetic refrigerants. Six standard models for use in the low capacity market exist. When comparing efficiencies, the SABlight exceeds hydrofluorocarbon chillers. The frequency-controlled standard compressor ensures a very high coefficient of performance (COP). Moreover, the wide control range makes it a highly flexible chiller that will operate efficiently even at low loads. The SABROE SABlight air-cooled chiller is tailored for outdoor installation with a very low-noise operation. The particularly compact design uses V-coil condensers to significantly reduce the total carbon footprint. With a height of only 2.9 m and a width of only 1.3 m, SABlight units are extremely manageable. …

Meilleures pratiques Saving 26.5% energy on HVAC Chiller system at the French Embassy in Thailand
The Embassy of France in Bangkok participated in the 2018 France Ministry of Europe and Foreign Affairs’ Green Embassy contest with its project to reduce energy consumption related to air conditioning. Installing CONTINEWM® Nets have contributed to save 26.5% of electricity consumption of the airconditioning (Chiller system) of the entire building and succeeded to place the project in the TOP 5 in the Green Embassy worldwide contest. The project consists in equipping the Air Conditioning system with the innovative CONTINEWM® Japanese technology from the French-Thai company Technic Electrical Engineering (Thailand) Co., Ltd. The reduction of the electricity consumption is equivalent to a validated reduction of 80 tons per year of CO2 emissions. The performance measurement was made by comparing the electricity consumption of chillers of the administrative building of the French Embassy WITHOUT and WITH CONTINEWM® Net under strictly same conditions and environment over a 3-month period under the control and validation of the Deputy Director of Buildings and Logistics, Deputy Director of Central Services and Logistics of the Ministry of Europe, Foreign Affairs and Development. These FIR emitting ceramic Nets optimize air conditioners and reduce energy consumption while improving the quality of the air by ionization. …
Meilleures pratiques Sectoral mitigation strategy – Transport refrigeration in South Africa
HEAT regularly applies a sectoral approach when striving to reduce emissions. Greenhouse gas (GHG) emissions inventories, low-carbon roadmaps and real-life pilot projects can effectively support sector transformation and low-carbon strategies. Aiming at the reduction of emissions from refrigerated transport in South Africa, HEAT supported the GIZ project Mitigating Emissions in the Transport Refrigeration Sector in South Africa in 2013-2017, funded by the Federal Ministry of the Environment, Nature Conservation and Nuclear Safety (BMU). HEAT identified measures to reduce emissions from refrigerated transport in trucks. The switch to natural refrigerant-based cooling systems and increased efficiency of those systems led to less direct emissions from the refrigerants and less indirect emissions from diesel to operate the equipment. Together with Transfrig, the leading local manufacturer, our experts developed and tested prototypes of climate-friendly refrigeration systems with 30% less energy consumption. Contribution to climate resilience: An improved cold chain leads to better food security and less health risks associated with perishable food. Optimized logistics and more efficient refrigeration systems cause less air pollution than conventional systems. Working with local companies regarding innovative technologies enhances vocational training, job opportunities and supports local operators and technology providers in their efforts to “green” their business. Moreover, the sector strategy introduced Measuring, Reporting and Verification (MRV) system procedures that can also be applied in other sectors. …

Meilleures pratiques Seminar: Seminar on the heating, ventilation and air conditioning sectors in Sydney, 2015
November 2015: The Australian Refrigeration Association (ARA) hosted a two-day seminar in Sydney to explore the possible contributions of the heating, ventilation and air conditioning (HVACR) industry in reducing greenhouse gas (GHG) emissions. Industrial, commercial and residential HVACR stakeholders were invited to an intensive two-day program highlighting the transition of the Australian HVACR industry to energy efficiency and emissions reduction. The ARA has estimated that Australia has the potential to reduce its HVACR energy bill and operating costs by over $10 B per annum and reducing national GHG emissions by 7% from the HVACR sector alone. The seminar addressed key issues impacting the Australian HVACR industry, providing stakeholders an opportunity to gain accurate information in the following areas: Exploring emerging HVACR energy efficient technologies and solutions Identifying and appreciating energy efficiency and GHG emissions reduction Quantifying and Recognising the value of integrated energy efficient engineering Recognising the regulatory requirements to shift to low GWP refrigerants Safety, risk and education – handling and implementing low GWP natural refrigerants …

Meilleures pratiques Success story: Air conditioning for world’s largest female-only university in Saudi Arabia
CAREL’s evaporative ChillBooster accommodates comfortable learning conditions in the world’s largest female-only university, the Princess Nora bint Abdulrahman University in Riyadh, Saudi Arabia. The ChillBooster is an evaporative cooler which cools air and lowers its average condensing pressure before the air is used by the condensing units such as chillers or dry coolers. Spontaneous evaporation is favored by the atomization of water in micrometric droplets, reducing the thermal energy required for evaporation from the surrounding air. Having opened in May 2011, the Princess Nora bint Abdulrahman University has a capacity of 50,000 students and hugely promotes female education. The ChillBooster guarantees a higher absorption ratio and less hygiene problems compared to the appliances typically used in such situations. …
Meilleures pratiques Success 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. …
Meilleures pratiques Success story: CO2/ammonia cascade systems
Research and Training Platform using natural refrigerants with particular emphasis being laid on the use of CO2 as refrigerant. A research and training platform using CO2 as refrigerant has been installed at the Université des Mascareignes in Mauritius. This project has been financed through the HPMP (HCFC Phase Out Management Plan) for Mauritius through the Ministry of Environment. The system has been designed to operate in three different modes: Ammonia in direction expansion, a Cascade CO2 operation with Ammonia Cooling the CO2 and CO2 in transcritical mode. The system is completely instrumented with temperature and pressure sensors as well as flow meters to enable trainees to do different kinds of manipulations. …
