How can the right choice of technology help protect the environment? Which policies can countries chose to enter a climate-friendly pathway? How to reverse ozone layer depletion? In times of climate emergency, HEAT provides advisory services as well as capacity building for the future. With a history of supporting Germany, as well as developing countries and economies in transition in their fight against the depletion of the earth’s protective ozone layer, the sustainable transition of the refrigeration and cooling sector is still at the core of our work. In particular, we provide emission inventories and mitigation pathways, advice on the development of policies, regulations and standards, as well as engineering services. We passionately develop capacity building and training to anchor knowledge on climate-friendly and energy-efficient technologies in our project partners’ countries and institutions. HEAT has implemented more than 300 projects in over 25 years. Our 40 staff members and experts currently assist projects in 30 countries. …

HEAT regularly applies a sectoral approach when striving to reduce emissions. Greenhouse gas (GHG) emissions inventories, low-carbon roadmaps and real-life pilot projects can effectively support sector transformation and low-carbon strategies. Aiming at the reduction of emissions from refrigerated transport in South Africa, HEAT supported the GIZ project Mitigating Emissions in the Transport Refrigeration Sector in South Africa in 2013-2017, funded by the Federal Ministry of the Environment, Nature Conservation and Nuclear Safety (BMU). HEAT identified measures to reduce emissions from refrigerated transport in trucks. The switch to natural refrigerant-based cooling systems and increased efficiency of those systems led to less direct emissions from the refrigerants and less indirect emissions from diesel to operate the equipment. Together with Transfrig, the leading local manufacturer, our experts developed and tested prototypes of climate-friendly refrigeration systems with 30% less energy consumption. Contribution to climate resilience: An improved cold chain leads to better food security and less health risks associated with perishable food. Optimized logistics and more efficient refrigeration systems cause less air pollution than conventional systems. Working with local companies regarding innovative technologies enhances vocational training, job opportunities and supports local operators and technology providers in their efforts to “green” their business. Moreover, the sector strategy introduced Measuring, Reporting and Verification (MRV) system procedures that can also be applied in other sectors. …

The number of room air conditioners is rising quickly throughout the world and especially in developing countries with warm climates. According to IEA, there could be over 3.7 billion room ACs in use in 2050. Emissions from room air conditioning will increase dramatically. Besides the decarbonisation of energy supply, increasing the appliances’ energy efficiency and using climate-friendly natural refrigerants are the only way towards zero-carbon and “green” cooling. HEAT has supported a pioneering room AC production conversion project which was implemented by GIZ and funded by the Federal Ministry of the Environment, Nature Conservation and Nuclear Safety (BMU). The Indian manufacturer Godrej ozone- and climate-friendly natural refrigerant R290 and started selling it in 2012. HEAT experts provided technical support for the new product design with a special focus on energy efficient and safe operation. HEAT also supported the elaboration of technicians training regarding the safe handling of flammable refrigerants in this context. In several related projects, HEAT experts have assisted the conversion to natural refrigerants in the production of household refrigerators as well as to natural blowing agents in the production of foam. …

A training workshop in the Philippines offered the opportunity to find solustions to create more incentives for consumers to invest in energy efficient and climate-friendly appliances. Like this the cooling sector in the country should be able to fulfil its crimate targets.

Ablehnung kein Bezug zu nat. Kältemittel /Cosysense provides a net zero service to commercial buildings like office and coworking spaces. Our plug-and-play sensors collect user comfort data, indoor environment, and HVAC power that we transform into real-time CO2e emissions. We complement it with databases of outdoor temperature, weather conditions, grid emission factors, and electricity price. We record all information in a serverless database and visualise it in digital dashboards. Our AI model uses the data for dual comfort and energy optimisation every 15 minutes. This represents the dynamic nature of buildings and people’s comfort needs. Looking ahead, we will add dynamic pricing and grid emission factors into the optimisation model for future grid-connected smart buildings. Our AI executes HVAC adjustments through battery-powered wall panel attachment that can be installed to approx. 80% of single and multi-split HVAC models with infrared or manual controls. We can install all our non-invasive devices in 1h without cutting a single cable in clients' spaces. Cosysense creates above 15% power and emissions savings on top of any other IoT existing solution. It has no upfront cost because we lease our sensors for free. Clients pay a subscription fee between $19 and $99 per sensor per month only if the savings we generate are larger than our fee. That is how our clients become more profitable and greener with our solution. …

MAGNOTHERM is an emerging university spin-off from Technische Universität Darmstadt with world leading expertise in permanent magnets and magnetic cooling. Our technology, based on solid state materials and water, is capable of replacing standard gas compression cooling or heating solutions in compliance with current and future f-gase regulation standards. Our developed cutting-edge energy conversion solutions allow cooling and heating with low pressure systems (approx. 0.5 bar) and is 40% more efficient than current systems. At the same time it complies with all current and future EU F-gas regulations, is explosion free and non-flammable. It is efficiently scalable in all sizes (from 0.5 to 5 kW) for thermal energy conversion units in decentralized, mid-range powered applications. With our 100% green technology, we are able to meet the world’s fast growing demand of clean and sustainable cooling and heating applications. …
