DE3239654A1 - Gas-electric or diesel-electric heating system with high degree of efficiency - Google Patents

Abstract

This heating system is characterised in that, during combustion of fuels suitable for internal combustion engines, as much energy as possible is converted into heat energy (if this is not anyway the case) or additional heat energy is obtained from the environment. As an internal combustion engine does not only supply the heat of the combustion but also mechanical energy (expansion of heated gases) and this can be partially or completely converted into heat again via a current generator (electric heating devices), a high degree of efficiency is guaranteed. A part of the mechanical energy can be used for the purpose of directly driving a heat pump in order to draw heat from the environment. The design of the system in terms of capacity depends upon the respective local, climatic and seasonal conditions and characteristics.

Description

with high efficiency

Diesel engines have been used to heat buildings for some time used. The aim was to use the mechanical energy that was released in the process with the help of an electricity generator to convert it into electrical energy and then to feed into the public power grid. However, this did not make it possible permit. Therefore, this type of heating of buildings is somewhat in the background devices.

On the other hand, the point in time is still a long way off when the heat generated by power plants can be found everywhere in the buildings in the vicinity of the Power plant supplies.

In addition, there are a limited number of so-called thermal power stations only relatively few households and industrial companies that use energy directly Form of heat.

The only option left for the rest of the building is to use such heating systems to use that when burning gas or heating oil by taking advantage of every imaginable Effects (such as the expansion of heated gases in internal combustion engines) have a high Have efficiency.

Since the burning of heating oil (gas) in a diesel (gas) The electrical energy obtained from the motor cannot be transferred to the public grid you should also use them to heat the building.

This could be done in a number of ways.

So one could add to an existing hot water central heating system install individual electric room heaters, which is a slight regulation of the individual room temperature. You could also use this Energy drive heat pumps, for example, the heat radiating from the engine Catch it and transport it to where it is required.

These heat pumps could also generate energy from the environment (solar panels, Process heat in industrial plants, warm waste water) into the building.

The drive can optionally be a) mechanical by means of a changeover switch and coupling from the engine, b) electrically from the generator and c) electrically from the public grid (in summer).

This type of heating can also be used, for example, in hospitals as an emergency power generator to serve. To do this, of course, some additional conditions must be met.

The heat emitted directly from the combustion engine (engine cooling system and exhaust gas) is most appropriately fed to the hot water central heating system. Included you can use a turbocharger with charge air cooling, as is the case with some automobile engines also use, which opens up another heat source. Also the one to reduce The sound absorber necessary for the noise nuisance can deliver quite a bit of heat.

The central heating system should, in case that radiated from it Heat in its environment is undesirable, encapsulated from the outside in a heat-insulated manner be so that all the heat inside the insulation by a heat pump to their Destination (free choice) can be guided.

In addition, a heat pump can be used through the outer walls of the building to intercept heat reaching the outside and to lead it back inside (Invention already exists).

The number of MNårmepumpea used depends on the size of the building, on the possibilities of the environment and on economic factors.

The setting of a certain voltage range at the output of the Power generator takes place by regulating the speed of the internal combustion engine and, if necessary by a transformer connected downstream of the generator.

additional mechanical or electrical energy can be used to (1) heat individual rooms (additionally) electrically, (2) additional heating water to heat electrically, (3) to heat domestic water electrically, (4) with heat pump (s) from the environment, (5) and the heating system with a heat pump isolate to the outside.

Claims (1)

Patent claim process for the simultaneous generation of WEtmXnergy, mechanical and electrical energy through an internal combustion engine, characterized in that that the mechanical and the electrical energy serve to convert into additional thermal energy To be transformed, or to draw warmth from the environment, or its escape to prevent the outside into the environment. Some of the electrical energy could be useful for emergency power purposes in the event of a failure of the public power grid.
