The Institute of Industrial Research (IIR) is one of the leading 13 Research Institutes of Ghana’s Council for Scientific and Industrial Research (CSIR), the main Science and Technology Research and Development Institution of Ghana. The CSIR-IIR is Ghana’s foremost industrial research and development organization.


CSIR-IIR Projects

CSIR-IIR designed, constructed and transferred a cool house technology to vegetable farmers in Kumasi to cut down post-harvest losses.

Throughout the period between harvest and consumption, maintaining optimum temperature which often requires cooling is the most important factor in preserving fruit and vegetable qualities. During cooling, heat is transferred from the produce to a cooling medium such as a source of refrigeration. Air conditioners are traditionally used as a reliable source of coldness but are electronically limited such that it cannot cool a room below 16°C.

To circumvent this challenge, a technology that involves the use of a micro-controller "brain" (CoolBot ) that intelligently control and coordinate the output of the air conditioner so that nearly all the cooling power can be accessed to keep temperatures in your walk-in cooler or any highly insulated room in close to 0°C without any freeze-up.

The CoolBot technology could also be adapted to use solar energy for the operation of the air conditioner in off-grid communities in Ghana. This CoolBot cool house technology is energy serving (about 65%) as compare to other refrigeration storage systems of same size. It is also convenient to use and easy to procure and install. The project sponsored by COTVET under the skill development fund, trained vegetable farmers at Gyinyasi in Kumasi on post-harvest handling, storage practices in vegetables and operation of cold house.
