Ozone and Cli­ma­te Fri­end­ly Coo­ling in West and Cen­tral Af­ri­ca (RO­CA)

The ROCA project promotes ozone- and climate-friendly cooling technologies in the four African countries Burkina Faso, Cameroon, Mali and Senegal. It started in April 2021 and will run until March 2024.

RAC appliances are spreading rapidly across Africa, particularly in the cities. In rural areas, on the other hand, there is still a lack of refrigeration equipment for agriculture and medical care. The rising number of RAC will contribute to increased energy needs as well as the use of refrigerant gases, many of which are highly damaging to the ozone layer and the global climate. To limit this dual impact, it is necessary to introduce a wide range of ozone- and climate-friendly cooling solutions.

ROCA (Refroidissement respectueux de l'Ozone et du Climat en Afrique de l'Ouest et Centrale) contributes to an increasing use of Green Cooling technologies through improving the policy and regulatory framework on the one hand and building capacity for the use of such technologies on the other.

ROCA includes the following measures: 

  • Analysing current and future cooling demands in the partner countries (RAC inventories)
  • Advisory services for the governments, based on RAC inventories and assessment of existing policies
  • Trainings of RAC technicians on safe handling of natural refrigerants online and in Germany (Cool Trainings) as well as in the partner countries
  • regional workshops on climate finance and business models to promote the accelerated adoption of ozone- and climate-friendly as well as energy-efficient appliances using natural refrigerants
  • Pilot projects using Green Cooling technologies; e.g.
    • Air Conditioning: R290-ACs for public buildings
    • Food Security:
      • cold rooms for agricultural cooperatives in Mali and Senegal;
      • an ice machine for a fishermen's cooperative in Senegal
      • a cold chain between the slaughterhouse and the market in Ouagadougou, Burkina Faso
    • Good Health: cooling for vaccines in Burkina Faso and for a hospital in Cameroon

The project is co-funded by the European Union and the German Federal Ministry for Economic Cooperation and Development (BMZ).

Cool Trai­ning Em­powers 15 Ref­ri­ge­ra­ti­on Tech­ni­ci­ans from Fran­co­pho­ne Af­ri­ca

26.05.2023 , News :

In a significant step towards promoting sustainable refrigeration practices in francophone Africa, GIZ Proklima in cooperation with the vocational training institute Bundesfachschule Kälte-Klima-Technik (BFS) recently conducted a two-week Cool Training. The training, held at the BFS in Maintal, aimed to equip refrigeration technicians from francophone African countries with knowledge and practical skills related to natural refrigerants.

A total of 14 participants from Mali, Cameroon, Burkina Faso, Senegal, and Mauritius enthusiastically engaged in the comprehensive training program. The participants explored the use of various natural refrigerants, including carbon dioxide, ammonia and propane, which are environmentally friendly alternatives to traditional synthetic refrigerants. With 13 of the participants participating through the project ROCA (opens in a new window) funded by the EU and the German Federal Ministry for Development and Cooperation (BMZ), and one participant from Mauritius through the respective HPMP (opens in a new window), also funded by BMZ.

The Cool Training program placed great emphasis on practical application, allowing the participants to gain hands-on experience and enhance their technical proficiency. Under the guidance of the experienced trainer Reiner Mayers, the technicians had the opportunity to practice working with natural refrigerants, familiarizing themselves with the equipment and techniques required for their safe and efficient operation. As team leaders, trainers and entrepreneurs, they will spread their newly acquired skills in their countries.

In addition to the training sessions, participants were invited to an insightful field trip to Nordfrost (opens in a new window), a company specialized in the use of ammonia refrigeration systems. This visit provided participants with valuable insight into the practical operation of an ammonia refrigeration system in use. They had the opportunity to observe and learn from industry experts and gained insights into the maintenance, operation and safety aspects of ammonia-based refrigeration systems.

The importance of this Cool Training program lies not only in the knowledge and skills the participants have gained, but also in the potential impact they can make in their home countries. By taking advantage of the training opportunities offered in Germany, these refrigeration technicians are now able to transfer their enhanced knowledge of natural refrigerants to their respective home countries.

This knowledge transfer will play an important role in introducing sustainable refrigeration practices, promoting energy efficiency and reducing the environmental impact of refrigeration systems in Francophone Africa.
