Tittle:
Autonomous heating systems based on solid-phase heat accumulators using night electric energy or/and surplus energy from wind power stations and/or solid fuel
Summary:
A small enterprise from Karelia, Russia, developed a compact heating system based on solid-phase heat accumulators made of soapstone with the capacity up to 100 kW. The system uses night electric energy, surplus energy of wind power stations, solid or gaseous fuel as energy sources. The system is ecologically safe, it costs 2-3 times less than analogues. The company seeks partners for technical cooperation.
Description:
One of the ways for optimization of energy consumption in buildings is application of autonomous energy supply systems, including the ones using night energy. These systems are economically, technically and ecologically more efficient than conventional boilers.
The developed solid-phase heat accumulator, with air as agent and the capacity of 2-100 kW, can provide a house of up to 300 sq.m. with heat and, if necessary, hot water. The heat accumulators can use night electric energy, unused (surplus) energy of wind power stations and/or mini hydro power stations. Some models can use solid fuel, including granules and briquettes obtained from wood waste, peat, coal, etc., or gaseous fuel as additional and equivalent energy sources.
The proposed heating system based on these heat accumulators is equipped with ventilation equipment, automatic monitoring and operating control system, devices for safe operation and indoor air humidity control. The heat accumulator is assembled onsite from supplied components.
The heat accumulating working medium in these systems is natural mineral - soapstone with a high heat resistance (it can stand the temperature range from -50C to +1000C), heat capacity and heat transmission. The service time of soapstone stoves is over 50 years, that is, equal to basic elements of brick buildings.
Application of soapstone allows creation of ecologically safe heating systems with a great integral heat capacity. The heat accumulator regulates air temperature in the heated premises; it is compatible with 'Smart House' systems, safe, easy to install, service and repair.
Use of heat accumulators with autonomous electric energy sources (wind power stations, floating hydro power stations) reduces the pay-back period of autonomous energy supply systems by 20-40% and increases the performance by 20-40%. The heat accumulator's ability to keep heat up to several days, if necessary, improves the reliability of heating systems with autonomous energy sources and in the areas with unreliable electricity supply.
Development of a heat accumulator of up to 200kW capacity is planned, basing on the company's experience.


Current and Potential Domain of Application: Autonomous heating and hot water supply to low- and high-rise buildings remote from central heating mains and/or boiler-house. Use in buildings and premises, where it is necessary to decrease costs on heating and hot water supply and improve reliability by using extra energy sources like biofuel and/or surplus energy of wind power stations, as well as to maintain the predetermined temperature precisely.
In rural areas, the consumer value of heat accumulators can be improved by using the energy of wind power stations and mini hydro power stations.

Advantages and Innovations:

Innovation of the technology is the developed compact low-cost heating system of sufficient capacity (up to 100kW) that can be integrated into any cottage, village house, flat or industrial building interior. The system uses several energy sources for heating and hot water supply.
The advantages of heating systems with soapstone heat accumulators are:
- greater unit capacity (up to 100kW) in comparison with analogs (up to 7kW),
- less cost per 1kW of capacity,
- there are specially located heat isolating ceramic air channels preventing air overheating in the heat accumulator (not more than +100-150C)
- heat accumulating medium is an ecologically safe natural mineral - soapstone (talcum peach),
- due to heat distribution regulation across the heated premises, air temperature is uniform over the height,
- reserve sources of energy can be used (solid fuel: firewood and peat, including waste in form of briquettes and granules, gas) in some models of heat accumulators,
- it is possible to accumulate a great amount of surplus energy from autonomous electric energy sources (wind power stations, floating and mini hydro power stations).
