Member Cool Up: Upscaling Sustainable Cooling
The Cool Up: Upscaling Sustainable Cooling programme promotes accelerated technological change in cooling demand reduction, and early implementation of the Kigali Amendment and Paris Agreement. Cool Up focuses on Egypt, Jordan, Lebanon, and Turkey as these countries are experiencing fast-growing demand for cooling, increasing final energy consumption, and structural challenges in the energy sector. They also have high potential to boost energy efficiency and increase the use of natural refrigerants in the cooling and refrigeration sector. The goal of the Cool Up programme is to create catalytic change within the refrigeration and air conditioning sector by reducing cooling demand, supporting the phase-down of hydrofluorocarbons, replacing and safely disposing inefficient cooling appliances and refrigerants, and improving cooling appliance operation, training, and awareness. Cool Up’s holistic approach addresses these issues across three themes: policy and regulatory support, development of business and financing models, and increased awareness and market uptake of sustainable cooling technologies. The approach is supplemented by implementation-focused partnerships and building hands-on capacity to enable local and regional stakeholders. Cool Up is led by Guidehouse Germany GmbH. The team includes Frankfurt School, ILK Dresden, Öko-Recherche, United Nations Development Programme, Regional Center for Renewable Energy and Energy Efficiency, Istanbul Aydin University, Integrated Development Group, Lebanese Center for Energy Conservation, and Royal Scientific Society. Cool Up is part of the International Climate Initiative (IKI). The Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) supports this initiative on the basis of a decision adopted by the German Bundestag. …
Member Solar Polar Limited
Solar Polar designs and makes solar thermal technology including solar cooling, solar heating and cooking. 1.5 Bn people worldwide live without grid electricity. At least half of them could benefit from an off-grid cooling system for uses such as medicines and food. This would have a massive socio-economic impact. In addition to this, we forecast that an average Mediterranean home using 4 kW of solar cooling would save approximately 13,000 kWh per year. This means saving €3,000 and 7 tonnes of CO2. Solar Polar solutions have a great potential in tackling these numbers, because it is affordable, modular and off-grid. …

Best practice Proyecto Coca Cola Stratum Liberia, Costa Rica.
This project is one of the most modern, technological and automated plants of Coca Cola in the world. It is a project of approximately $ 100,000,000.00 and 43,132 square meters of construction that has the LEED Silver certification. What was our work on this project? It consisted of starting up the complete refrigeration system of the plant, which included all the air conditioning, the cooling of the process water and the cooling of the refrigerated storage chambers and the freezing chamber. One of the most important conditions was to do an energy efficient and environmentally friendly project, and although the project was originally designed with ammonia, the required power and the volume of refrigerant in the system raised doubts about the application of this natural refrigerant. In term of refrigeration level, the plant required 750 TR in plant air conditioning and 150.0 TR in cold water systems for process and 208.0 TR in refrigerated and frozen storage systems. Originally the project was designed by other professionals, and the question at that time was not exactly the refrigerant, the question was oriented towards the ammonia volume of the system. The original design considered approximately 8 thousand pounds of ammonia. Our job then consisted of redesigning the project, it was then that we changed from a recirculated ammonia system to a direct expansion system for low temperature charging, where we used evaporators with a maximum ammonia volume of 2 pounds per equipment and, we maintained the water and propylene glycol cooling system with a flooded ammonia system; which in one way or another is also a low volume system. Our contribution was in addition to that, to increase the efficiency of the system, we increased the evaporation temperatures, we decreased the installed power and this represented an approximate energy saving of $250,000.00 per year and it was also possible to minimize the amount of equipment in the machine room. From an original design of 8 compressors we redesigned to 6 screw compressors of the same model and that came to give safety and an additional benefit for the maintenance . Entering the engine room we find 6 screw compressors, in this case they are Frick, they are 6 identical compressors in terms of model and power. We are going to find three plate heat exchangers, one for process water cooling, one for air conditioning water and another for propylene glycol cooling with which we air-condition the refrigerated storage chambers, named Water house and cool Flamable. We also found an ammonia dehydrator, which was incorporated to remove any moisture or water and thus maintain the efficiency of the system. In addition, we find that automation system, which one we not only control, we also monitor the entire refrigeration system of the machine room. Security and leak detection systems that comply with IIAR standards were incorporated into the system. It is basically an engine room where the entire volume of ammonia is concentrated, we are talking about 2800 pounds, 5000 pounds less than the original design. It is important to mention that the new design considered the use of heat of the oil compressor for heating the storage frozen floor and thus taking advantage of residual energy, a radiant floor was built. The main achievements of the project in terms of the redesign of the refrigeration system were the following: • The installed power of the cooling system was reduced by 472.5 Hp (352.49 KW). • The efficiency of the system was increased by 13.26%. • The ammonia volume was decreased by 4,822.00 pounds (2,187.24 Kg). • Ammonia, a natural refrigerant with a GWP of zero, was maintained. • The heat of the compressor oil was used in the requirements of the same system. • Equipment was standardized so that six compressors were installed identical in model and power. • A system was redesigned under the IIAR standards, the INTECO standards in Costa Rica, the Montreal Agreement and the Carbon Neutrality Country Program. • Savings were achieved in the initial investment. …
Best practice The air conditioning system to wear
Employees suffer from heat at their workplaces. Consequently, health problems and accident rates increase. But also the companies suffer from losses of productivity caused by heat. Stay cool at work with E.COOLINE cooling vests, cooling headgear as well as arm and leg coolers when temperatures rise over 26°C. This works at working places outdoors and indoors. The temperature load can be decreased by up to 12 °C on the skin which leads to a lower body core temperature and better health. In the meantime insurances as well as working associations recommend this alternative to air conditiong systems or other harmful technical solutions. Especially outdoors it is the only possibility. With the products of E.COOLINE you can not only save up to 90% CO2 compared with air conditioning systems but you use a carbon neutral product also at workplaces outdoors. …
