Objective A computer model was developed which allows the design to be optimised for the differing physical and environmental conditions. A design and assembly method was established with a super insulation which was approximately 10 times more efficient that the traditional refrigerator insulation, thereby reducing the heat gain the requirement for energy for the compressor. Tooling was developed to allow this. Designs and prototypes of the cool cell and cool cell material were tested successfully. The static system after modelling was selected rather than a dynamic pumped system. A cool cell design for a 39 litre and 110 litre refrigerators were carried out. Six prototypes of a cool cell refrigerator and six prototypes of a conventional evaporator design were constructed and tested. The evaporator design was optimised to have an increased internal surface with minimum refrigerant requirements. A programmable system controller/charger was developed for optimum control between the solar panel, battery and refrigerator internal temperature, charging the battery and charging the cool cell. The controller helped to maximise the operation of the compressor at it's maximum COP. Battery tests were carried out and a battery design established which could maintain the performance and low maintenance required under the conditions. Tests were carried out to validate the performance of the refrigerators. The cool cell refrigerator met the temperature requirements of the DIN ISO 7371 for the 'Sub-Tropical Class' Tambient= 38 C, Tcells less than or equal to 10 C and will probably meet the Tropical Class Tambient= 43 C. A model of the different design options and prices for different markets was established showing major cost reductions.
