Description

technical field

[0001] The invention relates to a system comprising: a pump for conveying a flow medium; an assembly for converting the flow medium from a liquid state to a gaseous state; a fluid machine for converting thermal energy of the flow medium Converted into mechanical energy; condenser, which is used to condense the gaseous flow medium into a liquid state. Background technique

[0002] Thermal processes can be carried out in a closed fashion. An example of a closed thermal process is a water-steam circuit in a power plant for the production of electrical energy. Here, water or steam is used as heat carrier and working medium. This cyclic process is called the Clausius Rankine Prozess.

[0003] At low process temperatures, the cyclic process also operates with organic flow media. This cycle process is called Organic Rankine Cycle (Organic Rankine Cycle).

[0004] Although the fluid medium in an Organic Rankine cycle is not strictly pure water vapor, the fluid m...

Embodiment Construction

[0029] figure 1 A conventional circuit 1 as already explained above is shown.

[0030] figure 2 A circuit 1 according to the invention is shown. exist figure 1 The circuit shown in and in the figure 2 The difference between the circuits 1 according to the invention shown in , is as follows: Between the condenser 4 and the pump 3 a cooling unit 7 is arranged. The condenser 4 is operated with cooling water 8 at which the flow medium is condensed. Cooling water 8 flows via pipe 9 into the condenser housing 10 .

[0031] The cooling unit 7 is designed to further cool the liquid flow medium. In one embodiment, the liquid flow medium is operated with cooling water 8 . in targeting image 3 A detailed description of the cooling assembly 7 is given in the description of .

[0032] The fluid medium is CO 2 , especially sCO 2 .

[0033] exist figure 2 The circuit shown in can be used in geothermal applications. For this purpose, no separate components are used in the ge...
