Solar Chill: Deploying Solar-Powered Environmentally Sound Freezers and Refrigerators in Off-Grid Areas
As of: August 2019
Objective and activities
The project is continuing the work of the SolarChill project that was launched in 2001. In cooperation with PalFridge, a local manufacturer of refrigeration equipment in Swaziland, it is developing existing prototypes to the point where they meet the needs of tropical and subtropical climatic zones while remaining affordable. This should facilitate the deployment of solar-powered environmentally sound refrigeration equipment in off-grid areas of Southern Africa. The appliances are free from climate-damaging refrigerants, use non-halogenated insulation foams, and operate without batteries which contain heavy metals.
State of implementation/results
- Solar-powered vaccine refrigerator developed and manufactured (MC72), which operates without climate-wrecking refrigerants
- Several training courses carried out in Swaziland and Germany (e.g. on welding aluminium microchannel evaporator tubes)
- Two types of solar refrigerators developed and marketed (around 400 during the project term)
- Agreement concluded with The Fridge Factory (TFF) to cooperate on the further development of the vaccine refrigerator (MC72 to MC100); tested successfully by the Danish Technology Institute according to WHO criteria; technology to be transferred to commercial and household appliances
- Several workshops carried out in Swaziland and Germany in cooperation with the project's partner focusing on redesigning the systems
- Technology presented at various international Forums
- GIZ and UNEP have decided to complement the technology transfer as well as the field tests by the GEF Solarchill Project
- The technology transfer, the production by TFF in Swaziland, as well as the field tests are planned for 2018 and 2019
- Development and production of solar-powered refrigerators in cooperation with the partner Palfridge in South Africa
- In order to test the vaccine coolers in the field, contact was made with rural clinics
- The idea of using a mobile application that links parents and nursing staff to each other was developed and took part in the internal GIZ tender for the Innovation Fund; the idea "Mum's Vaccination App" has been selected and can now participate in a seven-month accelerator program to develop the idea further.
