In achieving climate policy goals, decentralized energy supply plays a central role for both the energy and residential industries in the development of residential complexes. Large building complexes or even entire districts can be provided with energy in an environmentally responsible way by combining heat and power generation and the use of renewable energy sources. Especially for sustainable project portfolio management, it is important to provide heating at affordable prices. AHI Carrier offers the right solutions for the various challenges facing specialist industries.

Stuttgart Rosenstein in Stuttgart, Germany

Stuttgart Rosenstein in Stuttgart has an impressive, forward-looking heating and cooling concept based on innovative technologies. For this implementation, the customer and the energy planners chose AHI Carrier system components. Their perfect interaction allows you to obtain the necessary heat energy and part of the electrical energy directly in the residential complex itself.

The heart of the heating plant is a cogeneration plant that uses the principle of cogeneration to generate heat and electricity at the same time. The heat generated in this way is used for space heating and hot water for domestic use. Mechanical energy is converted directly into electricity and is used, among other things, to drive a heat pump.

Ice energy storage serves as heat storage

The ice storage consists of a tank with built-in heat exchangers, which is buried in the ground in the open air and filled with ordinary tap water. Special solar air absorbers are installed on the roof of the house. They take heat from the surrounding air and from solar radiation and feed it into storage. The ice storage also receives energy directly from the ground. The heat pump extracts the energy needed for central heating and DHW heating from the water stored in the tank as needed. If the temperature in the tank drops to freezing, more energy is extracted from the freezing water – hence the term "ice storage". At the end of the heating season, there is a selective formation of ice, which can then be used as a cooling source to keep the building cool on hot days. Changes in the physical state in the regeneration mode can be repeated as often as necessary: the technology requires almost no maintenance. A package of energy technologies is used as a contract model.

Stadtwerke Güstrow GmbH - heat and electricity for 500 households

Two Vitocrossal 200 gas condensing boilers cover the peak load

Edgar Föniger, Managing Director, and Hans Hall, Head of District Heating/Central Control Technology at Stadtwerke Güüstrow GmbH: "When expanding our district heating system, an energy-efficient and environmentally responsible supply is our top priority. For this reason, we use combined heat and power plants that run on bionatural gas. A decentralised CHP plant offers significantly higher efficiency and an excellent primary energy ratio compared to separate heat and power generation."

Stadtwerke Güüstrow GmbH supplies the housing cooperative with heat and electricity from two Vitobloc 200 cogeneration plants. Two Vitocrossal 200 gas condensing boilers provide heat during peak loads. Combined heat and power plants provide sufficient heat and electricity for 500 households. The modules run on bionatural gas within the scope of the Renewable Energy Act 2012.

Container Solutions

Systems that simultaneously generate heat and electricity are considered particularly cost-effective solutions for the commercial sector. Electric and heat generators installed in a commercial container, along with the appropriate accessories, are the ideal solution. Containers can be customized to meet specific requirements. AHI Carrier supplies powerful, turnkey container solutions with short installation times. They are specifically designed to operate on environmentally friendly fuels.

The heart of the system is a cogeneration unit that simultaneously generates heat and electricity. For enhanced environmental sustainability, it can run on gas from a nearby biogas plant. Biomethane from local gas networks can also be used. If necessary, it can be combined with a fossil fuel source (especially to cover peak loads).

Example: Biomass in containers - a space-saving solution

The Vitoflex 300-RF biomass boiler heats rooms with pellets. The storage container, located at the top of the heating container, holds 18 tons of pellets. A screw conveyor and gravity ensure seamless refilling of the environmentally friendly combustion system.
