    9. Types of Solar Cooling Solar open-loop A/C using desiccants Passive solar cooling Solar closed-loop absorption and adsorption cooling Photovoltaic (PV) solar cooling Geothermal cooling

    10. Solar Cooling – explained

    11. Basic Principle

    14. Recent Installations

    15. IS Fresnel collectors are designed to generate heat at 130 - 400 °C Technology Introduction

    16. Title: Solar refrigeration in industrial and commercial applications in Jordan Objective: Demonstrate feasibility and suitability of solar power for refrigeration in Jordan and the region; Expected outcome: innovative technology demonstrated, local knowledge established for replication, min. 1 lighthouse project up and running; potential for application and replication explored Official, governmental partner: Ministry of Environment; NOU Project duration: 2011-2014 30.08.2012

    17. Project goals Reduction of direct and indirect GHG-emissions: 670 tCO2eq/a (20,000 tCO2eq over 30 years life time). Demonstration of state-of-the-art technology Establishment of technology partnerships Elaboration of instruments and guidelines for replication Monitoring: establishment of a reliable monitoring 30.08.2012

    20. Complete the technical development of existing SolarChill prototypes -> to make the SolarChill concept suitable for use in temperatures over 45°C. support for set-up of a production line at the local manufacturer Palfridge (Swaziland) Emission reductions: Direct: every operational SolarChill unit avoids refrigerant emissions of approx. 0.2 tonnes CO2eq during lifetime usage. Indirect: 0.5 tonnes CO2eq /a per appliance (from avoided use of fossil fuels for electricity generation) 30.08.2012

    21. a small country in Southern Africa Population: 1,185,000 most Swazis live in rural homesteads the principal occupation is either subsistence farming or livestock herding

    22. Why Southern Africa? Why Swaziland? 69% of the population lives in poverty highest HIV infection rate in the world (26% of all adults) Tuberculosis a significant problem, 18% mortality rate lowest life expectancy in the world at 31.88 years There is the need for a sustainable solution for refrigerating vaccines and food!

    24. The philosophy Sustainability Simplicity Safety

    27. Cost of refrigerators

    28. MC72-Medical Unit Perfect equipment for hospitals, clinics, and ambulances. Chest type unit, 2 compartments: Vaccine storage + Freezer Mechanical damper regulates the amount of cooling and keeps it 2°- 8°C. Dampers and controller are preset to achieve optimum vaccine temperatures in all ambient temperature conditions. Ample insulation also allows for vaccines and medicines to be safely stored for extended periods of time in low light conditions.

    29. Operating Principles

    30. LC86-Commercial Merchandiser This is a commercial merchandiser comprising of controller and Danfoss BD35k compressor. Beverages are stored in shelf suspended from the top of the cabinet. The unit has a ballast load. The remainder of the space is filled with products. The controller is pre-set to achieve optimum beverage temperatures in all ambient temperature conditions.

    31. LS150-Domestic Unit is designed for the storage of fresh food, and is aimed primarily at rural homesteads and areas with intermittent power supply from the national grid. It is a single door design with separate fridge and freezer compartments that are able to maintain temperatures from 2-9°C. Ample insulation also allows for food to be safely stored for extended periods of time in low light conditions. The controller is preset to achieve optimum fresh food temperatures in all ambient temperature conditions.

    32. Next Steps: New design…new challenges.   We need to preserve medicine food & beverages for human consumption at high ambient temperatures ( 48°C ) using solar energy without the use of chemical storage batteries. Optimization of the product MC72 Result: an upgraded product MC73 with following improvement : significantly larger vaccine storage volume (above 50 l) significant reduced power consumption through utilising a new type of evaporator integrated with the ice keeping department completely battery free operation self cleaning condensor full conformity with the WHO specifications -> Agreement with NGO and distribution in Southern Africa
