The Green Chiller NAMA project supports Indonesia in creating framework conditions to improve energy efficiency and sustainability in the refrigeration and air-conditioning sector. Through development of a Nationally Appropriate Mitigation Action (NAMA) in the refrigeration and air-conditioning (RAC) sector a significant contribution to the achievement of the Indonesian GHG mitigation target will be made. The project focuses on four main areas: 1. NAMA strategy development 2. Establishment of incentive systems 3. Implementation of pilot measures 4. Capacity building …

MagFreeG, founded by Ubiblue in 2014, is a 30-month project aiming to commercialize and implement magnetic cooling across commercial cooling sectors in Europe. Under the CIP Eco-Innovation program of the European Union, MagFreeG received funding over 1.7M Euros. Ubiblue's MRS is the first industrialized, gas-free magnetic cooling system that offers a climate-friendly alternative to existing gas-based compressors for commercial refrigeration appliances. By introducing water-based MRS in professional refrigerated systems, MagFreeG may save up to the equivalent of 3200 tons of CO2 by the end of 2017, hereby enabling end users to contribute to the European 2020 environmental objectives. Currently, MRS has a cooling power of 400W, such that is applicable in smaller-scale appliances such as display cases or beverage coolers. However, MagFreeG is planning on extending MRS’s cooling power to 1000W, such that larger markets such as the industrial & medical refrigeration and transportation & storage can also benefit from this technology. …

The project “Promoting of Appliance Energy Efficiency and Transformation of the Refrigerating Appliances Market in Ghana” aims at improving the energy efficiency of cooling appliances marketed and used in Ghana. It is funded by the United Nations Development Program (UNDP) Green Energy Fund (GEF) and carried out by the Ghanaian Environmental Protection Agency. The project introduces a combination of regulatory tools such as Minimum Energy Performance Standards and Information Labels (S&L), as well as economic tools. Moreover, a Rebate Program encouraging households to replace old but functioning refrigerators with new and efficient ones has been introduced. The Ghanaian Energy Commission offers rebates of up to GH₵ 300 upon the purchase of new, Energy Efficient Labeled refrigerators. The Rebate Program was inaugurated on a pilot basis in 2012 for Accra and Tema, and was scaled up to cover all other regions by the end of 2013. The government of Ghana is providing GH₵ 1million per year for the Rebate Program, and the program will terminate once the funds are exhausted. …

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. …

Stemming from a successful bilateral relationship for over 20 years, the Governments of Bavaria and the Western Cape started a partnership project on the “transition to climate-friendly refrigeration and air conditioning” in 2017. The Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) is the implementing partner of the project, facilitating the transfer of best practice and technology between Bavaria and Western Cape. From 2018 to 2020, nine selected South African experts participated in a two-week Cool Training Course in Maintal, Germany, where they learned how the adoption of climate-friendly cooling appliances is viable both from an economical and technical perspective. In 2019, the Department of Environmental Affairs & Developmental Planning (DEA&DP), Western Cape Government, together with the Bavarian Environment Agency (LfU), hosted a two-day technical workshop in Stellenbosch on the transitioning to green cooling solutions. The result of the successful workshop was the development of a RAC Pilot Project. The West Coast College was selected as the first Technical and Vocational Education and Training (TVET) college in the Western Cape, to train refrigeration and air-conditioning artisans on the use of natural refrigerant gases, in particular with hydrocarbons. With a financial contribution made by the Green Cooling Initiative of GIZ Proklima for the training equipment, as well as the provision of the RAC Training Modules for hydrocarbons, the pilot project is planned to be implemented by September 2021. …

Colruyt Group choose propane compact chillers as the standard solution for commercial cooling in its' food shops in Belgium and Luxembourg. Cold brine (MPG) is used to distribute cold to the refrigerated cabinets and the cold rooms. The condenser is being cooled with the same MPG, so the heat is released outside with drycoolers or the waste heat is used to heat the shop. This layout allows for a very low refrigerant content of under 4,3 kg. The ventilated enclosure design means that no ATEX zoning exists outside the chiller. The connections are made with fast release flexible couplings, thus allowing redundancy and quick exchange of a chiller when it is broken. This reduces pressure on the internal maintenance team, which add to the safety of the solution. …
