Micro-TRIGENERATIONProject reference: 606108
Funded under :
Initial situation: The operation of small power plants (e.g. for households) for electricity, heat and cold (micro trigeneration) requires new solution trials. There are systems required, which are user-friendly, low-maintenance, economic. The new Schukey engine unites provide these attributes. The Schukey engine shows an ingenious concept (“universality as a concept”) and works at a temperature of 120°C steam or 1.1 bar. The cooling is directly made by air. In the Central Europe 5 kWel and 20 kWth are provided to 40 m² CPC-collectors. A household can cover ¾ of the annual heat demand (approx. 27 MWh) and current demand (approx. 4 MWh).
Difficulties: The Schukey technology is deciding in a very early developmental stage and thus it still requires a comprehensive development work: (1) Transmission compression, (2) Mass diminution (rotors & case), (3) coordination the control of the pressure volume temperature on the optimal expansion relationship of the domestic operating range, (4) creation of a thick system despite a smaller performance (max. 3% mass loss), (5) Integration into the primary domestic energy system or power supply system.
1. The priority aim of the project is the development and test application of a compact combination plan (10 kg of engine weight for 5 kWel) for a production of current, heat and cold in the smaller performance are by using of the Schukey technology – short “microsolar trigeneration”.
2. It should be directed a simple, standardized, economic and suitable for practices solution (for a Schukey engine should be obtained a performance area of 2-2.5kWel and a pure engine manufacturing between 300 and 500 €).
3. The project should aim for that specific current prime costs, which be directed in the area of the net parity (these should be long running). The cold of use should be provided by approx.0.5 €/kWh (conventional air conditioners: 0,12 €/kWh).
