Kindergarten: Heating with solar power

Project clean heat for kindergartens in cooperation with atmosfair and the NewClimate Institute (NCI) and kraftBoxx GmbH.

The project aims to improve the quality of life and environmental conditions in Mongolia by reducing dependence on coal combustion and promoting renewable energy sources. The project consists of two main components: the installation of photovoltaic systems and electric heating systems in selected institutions such as kindergartens and schools.

The photovoltaic systems are intended to cover local electricity requirements and reduce the power outages that frequently occur in the region. The electric heating systems are intended to replace traditional coal stoves, which cause high levels of air pollution and health problems. The systems are installed in cooperation with local partners who are responsible for maintenance and operation.

The project has several positive effects, both socially and environmentally. On the one hand, it improves the learning and working conditions in the participating institutions by ensuring a stable and clean energy supply. It also helps to reduce greenhouse gas emissions and promote the energy transition, which is crucial in the fight against climate change. The project is therefore an example of sustainable development that meets the needs of the present without jeopardizing the opportunities of future generations.

Advantages and challenges of the project: kindergartens

  • The 60 kWp PV system generates enough electricity to cover the company’s own needs and feed surplus electricity into the grid.
  • The Latent storage system uses the phase change materials heatSel to store heat efficiently and release it when required.
  • The air and heat pumps use the ambient air as a heat source, thus reducing energy consumption and operating costs.
  • The project improves the energy efficiency and CO2 balance of the building and contributes to climate protection.

Following an evaluation of the two tested systems, atmosfair plans to expand the project to other institutions, with kraftBoxx GmbH and the Mongolian company Solar Energy Consulting LLC implementing and supervising the systems as partners.

The project had a number of challenges during implementation, both of a technical and organizational nature. Some of them are:
  • The adaptation of photovoltaic systems and electric heating systems to the climatic conditions in Mongolia, which are characterized by extreme temperature fluctuations, strong winds and high dust levels.
  • The selection and procurement of suitable materials and components for the equipment and systems that meet quality and safety standards and ensure high efficiency and durability.
  • The coordination and training of local partners who are responsible for the installation, maintenance and operation of the plants and systems, as well as overcoming language and cultural barriers.
  • Electricity storage and management of the electricity generated, enabling optimal use of renewable energy sources and ensuring grid stability.

Mongolia: Heating with solar power

atmosfair finances and installs photovoltaic systems and electric heating systems in Mongolia, enabling institutions such as kindergartens and schools to switch from heating with environmentally harmful and unhealthy coal to solar power.

Mongolia - Ulaanbaatar

  • Utilize total PV surplus through stepless power modulation
  • Use additional latent heat capacity
  • 10 times higher performance compared to conventional Latent storages
  • 2 – 3 times the storage capacity of a water reservoir
  • 10 times cheaper than a comparable battery storage system
  • Capacity 30 kWh, 50 kWh and 60 kWh
  • Storage capacity increase by 3-4 times with the same volume, also easy retrofit possible.
  • Reduction of storage volume by 3-4 times with the same capacity, ideal for limited space conditions.
  • Increase service life – you benefit twice! – Peak shifting and extended run times.
  • Reduction of operating costs – reduce power peaks ( = connected load ) ( peak cutting / peak shifting ), use favorable “night electricity tariffs” and own production.
  • Simplified process control – by transforming the temperature peaks to phase change temperature and thus constant injection and withdrawal temperature. An integration as a thermal switch.
  • Higher efficiency – increase of COP (coefficient of performance) and reduction of heat losses due to constant temperature level (operating costs up to minus 40% !), use of smaller cooling/heating generators possible.
