Meilleures pratiques Training: Training programme for Iraqi refrigeration experts
Casale Monferrato, Italy, September 2016 – A group of Iraqi HVAC&R experts receive specialized training on the safe use natural refrigerants in domestic and commercial refrigeration. The training was hosted as a joint effort between Centro Studio Galileo and the United Nations Environment Programme (UNEP), and funded by the Multilateral Fund (MLF). During the week of theoretical and practical training, including field visits, the Iraqi experts gained the necessary skills and knowledge to support the introduction of hydrocarbon and low global warming potential refrigerants in the domestic and commercial refrigeration sectors. The training is part of Iraq’s national strategy for phasing out hydrochlorofluorocarbons (HCFCs) while reducing dependency on high-GWP refrigerants. The participants were certified after successful completion of the course, such that they are now responsible for conducting training courses for local Iraqi engineers and technicians. Centro Studi Galileo and UNEP have worked together for over 10 years to build the capacity of technicians in developing countries and to support the introduction of local certification schemes for refrigeration technicians. …
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. …

Direct fired biomass absorption cooling unit Biomass trigeneration allows for combined cooling, heating and power generation. Using solid biofuels on a small scale decentralizes biomass consumption and decreases logistical issues. An environmentally-friendly option for buildings where the heating needs are higher than the cooling demand. …
Meilleures pratiques Training: Training workshop for ice machine makers
August 2015: In supporting the implementation of the Hydrofluorocarbon Phase-Out Management Plan (HPMP) in Nigeria, the National Ozone Office (NOO) together with the United Nations Industrial Development Organization (UNIDO) organized a training for ice machine makers on the installation and maintenance of low pressure foaming machines. The training was held in Abuja on August 11th and 12th, and in Ibadan on August 27th and 28th. The NOO of the Federal Ministry of Environment inaugurated the trainings for ice machine makers under HPMP Stage I. The training in 2015 was so successful that another one was held in June 2017. HPMP Stage I has been successfully completed and Stag II is well under way. Under the Kigali Amendment to the Montreal Protocol, Nigeria, as every other developing country, has committed to completely phasing out hydrofluorocarbons (HFCs) by 2040. The year 2009/2010 is used a baseline, with a 10% phase out by 2015, a 35% phase out by 2020 and a 67.5% phase out by 2025. …
Meilleures pratiques Policymaking: ATMOsphere: The business case for natural refrigerants
Organized and hosted by Shecco, ATMOsphere are a series of international annual events bringing together stakeholders involved in natural refrigerant-based technologies. Since 2009, 30 ATMOsphere events have taken place in Europe, Asia, Australia and America. ATMOsphere events assemble key industrial, public and political stakeholders, as well as end-users to discuss natural refrigerant-based technologies. The event uses market trends and regulatory sessions, consumer and supplier panels, technology case studies, workshops and networking opportunities to explore and promote the business case for natural refrigerants. …
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. …
Meilleures pratiques Policymaking: The Natural Voice- A global call to reduce greenhouse gases by natural refrigerants
Introduced by Shecco in 2009, the Natural Voice is a global statement open to industry, associations, non-profit organizations and individuals supporting the potential of natural refrigerants in replacing potent greenhouse gases. At present, the Natural Voice has 109 signatories from a range of sectors and industries. The statement will be presented to national governments and international climate negotiators in the near future to build the basis for developing natural refrigerant initiatives around the world. The Natural Voice demands national governments to remove (inter)national trade barriers and to revise safety standards, codes and legislation that restrict the use of natural refrigerants without merit. Furthermore, it calls upon national governments to provide (non-) financial support for the research and promotion of natural refrigerants, and to facilitate the technology transfer from developed to developing countries. …
