trying to reduce the ratio of volume to the area to increase efficiency and effectiveness of the designed HEX …

At the energy lab here at KTH, we are developing efficient HVAC systems and applications as well as waste heat recovery systems such as heat pumps and geothermal applications. Our research projects concern the design of refrigeration and heat pump systems, and what can be done to make these systems more energy efficient and their environmental footprint smaller. To obtain the previously mentioned added values, we build, commission, and test specific projects investigating how natural fluids, like propane, carbon dioxide, and ammonia, could be used in a safe and efficient way as refrigerant. Refrigeration systems and heat pumps, especially High Temperature Heat Pump (HTHP), become more efficient if the heat exchangers, evaporator and condenser, are efficient and give small temperature differences. For this reason, we have research projects on enhancing the surface area to volume ratio of the heat exchangers using additive manufacturing technologies (Metal 3D Printers) to attain the best ratio. …

iCS and a network of NGOs provided technical support to INMETRO for the revision of the Brazilian Labeling program for room ACs. This network also actively worked to pressure INMETRO to adopt a more ambitious energy efficiency levels. The process resulted in the Ordinance 269/2021. …

The Institute for Climate and Society (iCS) is a philanthropic organization that promotes prosperity, justice and low carbon development in Brazil. We operate as a bridge between international and national funders and local partners. Consequently, we are part of a wide network of philanthropic organizations that are dedicated to finding solutions to the climate crisis. iCS outlines plans of action to overcome climate problems from a social perspective. Therefore, it prioritizes measures that, in addition to reducing greenhouse gas emissions, also result in improvements in the quality of life for society, especially for those most vulnerable.​ The main activity of the Institute is to provide grants in order to promote projects and organizations that seek to: • BUILD evidence that qualifies the debate and supports the decision-making • PROMOTE advocacy, campaigns and communication • CREATE spaces of interaction between different actors and sectors • ENCOURAGE the exchange of knowledge and experience between Brazil and the rest of the world​ Furthermore, we are also dedicated to the engagement of society with the subject of climate change, the implementation of our own projects and the institutional training of civil society organizations. …

KEREN ENERGY has developed a holistic approach to saving energy: an Energy Diet based on the equipment that the user already has. In this case, the monthly energy bill is the “scale” of success. The real game changer is the public awareness and participation. Today, people can start weight loss diets to look better, but with the “National Energy Diet” we all can be on our way to a much better, sustainable, and economical life. Furthermore, Keren Energy provisions the Clima-Med project. The project is funded by the European Union and seeks to support the transition of eight partner countries in the South Mediterranean region towards sustainable, low-carbon and climate-resilient development.
