Definitions

  • the invention relates to a combined heat and power Einrich ⁇ tion, based on the technology of a motor-block heating power plant for the thermal and electrical energy supply of buildings and facilities using fossil and or regenerative primary energy.
  • CHP plants of the type mentioned are, for example, from
  • enclosures serve primarily for heat and sound insulation of the CHP in order to achieve the highest possible degree of utilization of the primary energy used, and the waste heat, while minimizing the emission of noise.
  • a particularly efficient solution for a heat and sound ⁇ insulating housing of a CHP is also known from DE 101 51 121 B 4.
  • This housing is then replaced using the generator ventilation terrades or an additional fan / compressor constantly subjected to an increased internal pressure Due to the air ⁇ tight enclosure can not escape warm indoor air from the enclosure. Thus, the thermal losses can be minimized in connection with the thermal insulation.
  • the disadvantage of this solution is that due to the internal pressure increase according to the invention an absolute airtightness of the housing must be achieved, otherwise permanently warm indoor air can escape into the surrounding atmosphere and thus ⁇ arise with additional thermal losses.
  • the invention is based on the object of a further ver ⁇ improved enclosure for a CHP with a more effective heat and sound insulating effect indicate that ensures best use of the primary energy and an even more effi ⁇ cient utilization of the waste heat of the engine and the generator, and doing with minimal investment and operating costs.
  • the core of the invention is a CHP, which is surrounded by a heat and sound insulating, and hermetically well, but not necessarily completely dense housing.
  • the solution according to the invention thus differs from previously known enclosures, in particular from DE 101 51 121 B4, inter alia, in that it operates relatively slight negative pressure inside the enclosure in the operating condition with a ge ⁇ geninate the environment. This operating mode ensures that the enclosure surrounding the CHP does not have to be 100% airtight and at the same time stable and resistant to internal pressure.
  • the implementation of the invention is achieved by the CHP and the enclosure is preferably designed in a cylindrical shape, whereby a simple production while simultane- ously efficient vacuum resistance is ensured.
  • the housing has an air supply ⁇ opening with an integrated flow resistance.
  • This preferred adjustable supply air opening managed the majority of the necessary for the internal combustion engine
  • the flow resistance which is designed for example as a va riable ⁇ external throttle can be used for setting and regulating the vacuum in the housing. Since the enclosure resp. the housing according to the invention is always acted upon with ei ⁇ nem vacuum, thus no warm air flows to the outside. In this way, no heat losses caused by unwanted warm air transport to the outside. In cooperation of the generally common engine throttle valve of the carburetor with the additionally provided variable flow resistance of the respective desired negative pressure in the enclosure can be accurately adjusted.
  • the lambda value can also be controlled very well as a measure of the quality of the combustion. Due to the large volume of the housing compared with the engine displacement, this acts as a reservoir and, in conjunction with the variable flow resistance, as an attenuator, thus improving the control results based on the lambda value in a sustainable manner.
  • the CHP plant according to the invention can be used anywhere where still conventional gas, oil or solid ⁇ heaters are installed.

  • the internal combustion engine can be designed as a gas, gasoline or diesel engine or as a turbine.
  • the use of a fuel cell is also possible.

  • the generator 2 is connected via a regenerative frequency converter 10 and the electric energy meter 11 to the home network and the public grid.
  • a frequency converter By means of a frequency converter, the generator, which is preferably designed as an asynchronous machine, is also used to start the CHP.

Abstract

L'invention concerne un dispositif à couplage force-chaleur amélioré pour l'alimentation en énergie thermique et électrique d'immeubles et d'installations. Selon l'invention, la centrale thermique en montage bloc se trouve dans une enceinte fermée (12) soumise en fonctionnement à une dépression commandée en permanence. La dépression dans l'enceinte (12) est régulée au moyen d'une recirculation partielle des gaz de combustion (14) dans le canal d'aspiration du moteur à combustion (1), et d'un élément de résistance à l'écoulement externe supplémentaire (6) prévu dans l'enceinte fermée (12), un convertisseur de fréquence (10) capable d'effectuer une alimentation en retour étant connecté au générateur (2). L'invention permet de récupérer très efficacement de la chaleur, de minimiser essentiellement les pertes de chaleur et d'obtenir, en combinaison avec la recirculation des gaz de combustion et le convertisseur de fréquence capable d'effectuer une alimentation en retour, une très grande modulation de puissance tout en minimisant l'émission de polluants tels que CO, HC et NOx.
