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. …
Best practice 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. …
Best practice 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. …
Best practice 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. …
Best practice 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. …
Best practice Policymaking: National HCFC phase out management plan
In order to achieve a 65% reduction of HCFCs by 2025, the Bangladesh Department of Environment (DoE) is planning Stage 2 of its HCFC Phase-Out Management Plan (HPMP), funded by the Multilateral Fund. Bangladesh’s HPMP Stage 1 includes an investment component and a technician and customs training component. An 18% reduction in HCFCs after the successful completion of Stage 1 by the end of 2017 is expected, after which HPMP Stage 2 will commence. To achieve the 35% phase-out target in 2020 and in preparation for the 65% target by 2025, set forward in the Kigali Amendment to the Montreal Protocol, the DoE is currently preparing HPMP Stage 2. As a signatory to the Vienna Convention and the Montreal Protocol, Bangladesh inaugurated its Country Programme to phase-out the consumption of Ozone Depleting Substances (ODS) in 1994, with the formation of the National Ozone Unit in 1996. The Country Programme proposed the introduction of regulatory measures, spreading awareness and information as well as training and funding for technological conversions to comply with the country’s climate goals. …
Best practice Literature: Chilling Facts
The seventh edition of the Environmental Investigation Agency’s (EIAs) Chilling Facts demonstrates that the uptake of HFC-free technology is rapidly advancing in the EU, especially in Eastern and Southern member countries. Since 2008, EIA has been conducting surveys on the use of natural refrigerants in various EU supermarket chains. Annual reports document the market-shift towards climate-friendly refrigerants among some of the world’s leading retailers, as well as warning slow adopters of possible financial problems. In the lastest edition of Chilling Facts, the EIA estimates that 9000 CO2 transcritical systems are in use EU-wide. 6000 additional systems are expected yearly as the EU F-gas phase down progresses. Moreover, innovative CO2 transcritical systems with parallel compression and ejector technology will enable the use of CO2 systems in warm countries. …
Best practice Success story: first CO2 training facility in South Africa
Johannesburg, February 2016- Commercial Refrigeration Services (CRS) has opened the first ever CO2 training facility and showroom in South Africa. The new facility is used to train local technicians and contractors on installing and maintaining CO2 systems. Groenwald, CRS’ head of engineering, manufacturing and installations said that “knowledge and experience are the barriers standing between CO2 refrigeration applications becoming the mainstream solution for the African market”. The readily accessible CO2 facility in Johannesburg is helping local technicians to understand the climate-friendly and energy-efficient efficient alternative refrigerant. The facility resembles a small supermarket with three different CO2 refrigeration systems: a booster system, a booster system with parallel compression and a booster system with parallel compression and an ejector. By measuring and analyzing the energy consumption by the different types of systems, CRS may demonstrate to the end users the monetary, energy and ecological benefits of each CO2 refrigeration system. …
Best practice Product: CO2 Booster System ONYX
The ONYX series are simple, integrated transcritical booster systems for medium (MT) and low temperature (LT) supermarket applications designed by Commercial Refrigeration Services (CRS) South Africa. The ONYX CO2 booster system makes use of parallel compression and ejectors, increasing energy efficiency by 25-35% and making CO2 a viable refrigerant choice even in high temperature regions. ONYX uses a two-stage compression cycle with a common condenser and liquid line for MT and LT applications. The two-stage design prevents significant energy losses as no big heat exchangers are required to condense the LT side. The integrated multi-temperature solution thus allows each ONYX unit to fully exploit the advantages of CO2. …
Best practice Success story: Green Cooling labels for refrigerants in Grenada
Since May 2018, the National Ozone Unit (NOU) of Grenada, in cooperation with GIZ Proklima, has been providing Green Cooling stickers to local appliance stores in order to promote the dissemination and use of natural refrigerants on the island state. The initiative created by both project partners supplies local appliance stores with eye-catching green magnetic stickers which are fixed on refrigeration systems with natural refrigerants. As a result, both the distributors and the customer alike are provided with a convenient tool for the promotion and distribution of natural refrigerants, and thus for ozone and climate protection. First piloted with the two companies Courts Grenada Limited (UNICOMER) and L. A. Purcel, the NOU aims to involve more retailers and suppliers and expand the initiative also to air conditioning technologies, with the goal of eventually making Grenada the first f-gas-free Caribbean island. …
