Translation of "Niedertemperaturwärme" in English

Conversion technologies for electricity production from low-temperature heat have a great deal of optimisation potential.

Furthermore, low-temperature heat 11 is discharged by the flue gas purification apparatus 62 .

A newly developed steam expansion engine uses low-temperature heat with ORC technology.

A prerequisite for using such low-temperature heat is an energy efficiently optimised building envelope.

Solar thermal energy will proportionally cover the need for low-temperature heat in buildings and industry.

Additionally it has been investigated to what extend low temperature heat can be covered by solar energy.

Furthermore, fuel gas preheating with low-temperature heat from the power plant is a possible way to increase the overall efficiency of the plant.

Analogously, low-temperature heat can also usefully be used for regeneration of the CO 2 absorber or adsorber.

The transfer of heat into mechanical and electrical power plays a major role in the field of renewables.

In 2002, SorTech AG (renamed Fahrenheit AG as of March 2017) was spun off to exploit heat sources for producing cold, thus using low temperature heat as an energy source instead of electricity.

In the known process, the weak solution of the two working substances used to pick up the low temperature heat is passed through the solar collector, and the cooling medium which is evaporated there, (which comprises the strong solution of the two working materials), is passed into the absorber.

Thus, the working media of the invention allow a high coefficient of performance (COP) of the adsorption cooling/conditioning unit, that is to say the ratio of cooling power to invested thermal power from the low-temperature heat turns out to be extremely favorable.

In this way, the throughput of medium in the circuit through compressor 2 and the mass flow circulating in the circuit 1 can be adapted to the requirement for heat and the supply of low temperature heat in the same way.

The low temperature heat is won through condensation of a portion of the vaporous head product or through condensation of vapor which is branched off between the installation sections of the upper part of the column.

In other compositions, the dispersions cover the temperature range from 25 to 45 °C and are designed for transporting or storing low-temperature heat.

Researchers from Saarland have developed an engine that uses low-temperature heat to generate electricity very efficiently for a large range of uses.

Indirect conversion technologies, primarily those in which low temperature heat is converted to electricity (e.g., magneto-caloric conversion, thermoelectrics, osmotic processes);

Significant contents of the study are, furthermore, computer-aided dynamical simulations of the energy exploration and storage in relation to the heating and cooling demand of the modernised building stock as well as the energy distribution in low temperature and cool grids.

As a particular innovation for the grid-tied heating provision of building development areas with low building densities and high thermal protection standards, the energy-plus housing estate will realise a so-called cold local heating network, which via agrothermal collectors and waste heat from a neighbouring supermarket will be supplied with low-temperature heat for the decentralised heat pumps.

Higher yields due to lower system temperatures and reduced system costs due to simpler design overcompensate the active frost protection by heating the collector field with low-temperature heat in the few frost pits.

This is possible because, in order to regenerate carbon dioxide, only low-temperature heat is required, which can ideally be provided by regenerative energy sources.

By way of example, the low-temperature heat which is emitted in the cooler 38 can be used for feed-water preheating in one of the steam processes, and/or for preheating of the fuel gas 37 .

In addition, the preheating of the working medium in the ORC in two steps in a heating device is known from German Patent No. 10 2005 048 795, i.e., that the process medium in the ORC is heated by two heat exchangers connected in series downstream from a feeding pump; the first heat exchanger downstream from the feeding pump is provided as a first stage for the incoupling of low-temperature heat, and the following heat exchanger is provided as a second stage for the incoupling of high-temperature heat.

The mixture cooling of the combustion engine is connected, via a circulation system, to the first heat exchanger downstream from the feeding pump, the heat from the cooling of the combustion-gas mixture aspirated by the combustion engine being used to preheat the process medium in the ORC and coupled into the first heat exchanger as low-temperature heat.

The heat supply apparatus which can be arranged here is particularly highly suitable for use of low-temperature heat, such as solar heat or other heat that occurs at a low temperature level, since the storage fluid flowing through is at a low temperature.

The heat exchanger 41 is, in addition, particularly well suitable for use of low-temperature heat, such as solar heat or other heat that is produced at a low temperature level, since the inlet storage fluid is at a low temperature and there is generally no need for a high inlet flow temperature for the expansion machine 21 .

The (still-vaporous) operating medium which is brought to condensation temperature in the turbine and in the regenerator, if applicable, finds its way into the downstream-connected condenser in which the operating medium is recondensed, yielding low-temperature heat.

Process heat forms the main part of the energy demand in industry (21 %) and is used in large part for generating low temperature heat.

The low temperature heat is in fact used to heat water to 35-40 degrees, with the flour, is used to produce the dough, which is worked in the kneading actuated by electric energy generated by the CHP.
