The technology is based on the use of SelfChill Cooling Units, which create a modular water chiller(ice-storage). Ice is generated during day while stored ice provides cooling energy at night through a water pump and a heat exchanger. The cooling units are run by DC current from the PV panels without the need of inverters. Fully modular and of course using ultra low global warming potential(GWP) refrigerants only!
We thank the entire Efficiency for Access coalition, Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH within its Powering Agriculture Programm, and the University of Hohenheim to support the development of the SelfChill approach.
Thanks to DEG and its Developpp program for co-financing the instalation.
Last but not least, the operator of the cold room Jungle Harvest Ltd Farm in Thika, Kenya. For making the business model behind the introduction of the cold room become a success!
The SelfChill team is composed by Solar Cooling Engineering GmbH as developer of the technology, Phaesun GmbH as distributor and integrator of SelfChill components, University of Hohenheim and its institute of agricultural engineering in the tropics and subtropics as research partner. Our SelfChill partners in Africa get the components they need from us and source the rest locally. Within trainings and engineering support, they commercialized innovative cooling solutions made in Africa.
Together we are strong, dynamic, resilient and cost efficient!
