The main purpose:

development and accumulation of technological knowledge regarding mCHP-Ssystems of generating energy as durable alternative, with primary accent on primary

energetic resources in quality and supply safety conditions and with keeping the principle

of durable development.

The proposal also contributes to the development of theoretical knowledge due to itscomplex and multidisciplinary theme, due to the performance of an experimental model

and the necessity of theoretic fundaments of interface solutions for mCHP-S systems

independent functionality and efficient usage of sub-systems by accomplishing process

and interaction models. Also, considering heterogeneous criteria and optimization

(electrical efficiency, thermal comfort degree, etc.), quality (quality of suppliedelectricity, functional quality criteria) and durability (specific maintenance, use safety,

lifetime) complexes, it contributes to the augmentation of analysis capacity and ability to

offer viable solutions to nowadays complex problems.).

in mountain areas mCHP-S system can be adapted to classical or modern heating installation thatis based on inferior or regenerable fuels.

Thermal comfort index in a residential building becomes critical in noelectrified and/or isolated areas, where substantial investments are made in

acquisition of separate units: electricity supply unit (electrogen unit) and heating

unit based on liquefied gases (LPG).

The project proposes the capitalization of CHP systems general advantages

augmentation of fuel usage efficiency,

low emission of CO2, consumers energetic independence with the advantages of using Stirling motors

is developed on three main directions

gathering knowledge (combustion processes, choosing performing

materials, elaborating molding and specific stimulation methods,

optimizing criteria)

-applicable research (achieving a new, innovative product)

-technological transfer (transfer of obtained results to economic agents,small and middle enterprises in order to attract them in new research-

In conformity with C.E directive no. 8/2004 of European Council Parliamentregarding cogeneration promotion, combined production units with unite

electrical supply

from few kW to 50 kW are micro-CHP, between 50 and 1000 KW are of average power and

between 1000kW and maximum 10 MW are of high power.

The project takes into consideration the usage of inferior fuels in generating heat and

electricity directly at consumers area, using a system that contains, heat generator-

Stirling motor-electrical generator-static inverter and a command, monitoring and

protection system in order to compensate fuels quality variability.

The main disadvantage of using other types of thermal motors (first step of CHP

conversion) in residential heat supply systems is the need of high quality fuels

(mineral oil, natural gases, liquefied gases).The augmentation of superior fuels need also increased their prices and costs in

producing thermal energy.

an immediate effect is represented by the positive effect on the market as an alternative for electrical autonomy, forreducing cost of isolated consumers by capitalizing the energetic potential of inferior fuels (that are anyway used in

heating).

The hybrid system is designed to assure energetic autonomy can be implemented, especially, in isolated areas or withlow regional development. Using this energetic system, the user does not only become consumer but also energy producer.

Is estimated that the main social effect will be augmentation of life conditions to European standards, reduction of

differences between rural and urban residential areas and mainly the presentation of a solution for the resolution of comfortproblems for consumers in no electrified and/or isolated areas that have access to inferior fuels.

An efficient and viable mCHP-S system that incorporates new performing materials and where conversions aremade at maximum efficiency can increase its interest and applicability area.

mCHP-S systems important elements demand new and innovatory ideas in order to elaborate competitive and

attractive equipments for a technological transfer.

T he key of the proposed project is the integration of high technology (IT) at MPCS level, meaning developmentsystems with microprocessors, specialized software to involve young specialist that bring performance to this domain.

Not to neglect is also the special domain ofmaterials used in technologies to elaborate mCHP-S systems element forwhich the conversion efficiency becomes the main choice and development criteria.

Environmental effects are important from the following point of view:

in search of superior fuels (stable, expensive, efficient), part of inferior fuels are rarely used and in this way become pollutant for environment

(wood, biomass and biogas wastes).

Their transformation in electrical and thermal energy in CHP systems with high efficiency determines thedirect abatement of emission with greenhouse effect (CO

2) and possibility to eliminate some wasted through

burning.
