    [0002] Combined cycle thermoelectric plant between reverse Brayton cycle assisted with low and / or high temperature heat and a thermal machine and its operating procedure.
    [0003]
    [0004] TECHNICAL FIELD OF THE INVENTION
    [0005]
    [0006] The present invention entitled "Combined cycle thermoelectric plant between reverse cycle Brayton assisted with low and / or high temperature heat and a thermal machine and its operating method" belongs to the technical field of combined cycle thermoelectric plants that perform the conversion of thermal energy to electrical energy using low temperature waste heat and high temperature heat from external sources.
    [0007]
    [0008] Objective of the invention
    [0009]
    [0010] The present invention called "Combined cycle thermoelectric plant between reverse cycle Brayton assisted with low and / or high temperature heat and a thermal machine and its operating method", aims to use the low temperature heat, which includes residual heat of industrial, solar, geothermal, thermo-oceanic, lakes and rivers, and high temperature heat from an external source to produce mechanical work and / or electricity based on the combination of two thermal modules: a primary module formed by the cycle Inverse Brayton (Bl) fed with low temperature waste heat and high temperature heat from an external source, and a secondary module formed by any thermal machine working between two heat sources such as a Rankine cycle, a Brayton cycle or a machine thermal capable of performing work by adding and subtracting heat.
    [0011]
    [0012] BACKGROUND OF THE INVENTION
    [0013]
    [0014] The known thermoelectric plants that use combined cycles are constituted by a primary module formed by a Brayton cycle and a secondary module formed by a Rankine.
    [0015] In the case of this invention, the primary module is formed by the cycle Bl fed with heat of low temperature and high temperature, while the secondary module is optionally formed by any thermal machine working between two sources of heat, high and low temperature respectively, such as a Rankine cycle, a Brayton cycle or a thermal machine capable of performing work by addition and subtraction of heat.
    [0016]
    [0017] Consequently, in the current state of technology, no generation technique using the form described in cycle Bl is known.
    [0018]
    [0019] Description of the invention
    [0020]
    [0021] BRIEF DESCRIPTION OF THE INVENTION
    [0022]
    [0023] The invention called "Combined cycle thermoelectric plant between reverse cycle brayton assisted with low and / or high temperature heat and a thermal machine and its operating procedure", consists of a combined cycle between a primary module formed by cycle Bl operating with helium and the secondary module optionally formed by any thermal machine working between two sources of heat, high and low temperature respectively, such as a Rankine cycle, a Brayton cycle or a thermal machine capable of performing mechanical work by adding and subtracting heat such as those described in the Spanish patent applications 201700667 and 201700718 (heating and cooling of a working fluid), where the primary module formed by cycle Bl provides the two thermal foci that make up both the thermal source or high temperature heat reservoir as the thermal sink or low temperature reservoir, and where such high and low temperature thermal focuses perform the functions of thermal heat source and thermal heat sink, necessary in all the thermal machines susceptible of implementation that make up the secondary module, which can optionally consist of any thermal machine that works between two heat sources of high and low temperature, such as a Rankine cycle, a Brayton cycle or a thermal machine capable of performing mechanical work by adding and subtracting heat such as those described in the Spanish patent applications 201700667 and 201700718.
    [0024]
    [0025] The primary module formed by cycle Bl captures low temperature heat, which includes waste heat from industrial, solar, geothermal, thermo-oceanic, lakes and rivers, by means of a heat exchanger located at the suction of the compressor, heating the fluid from work (helium) which, when compressed, acquires a higher temperature and subsequently captures high temperature waste heat by means of a heat exchanger located at the compressor discharge, to perform the high temperature thermal source function of the thermal machine that make up the secondary module.
    [0026]
    [0027] This thermal source of heat, when thermally feeding the secondary module, yields heat that converts into mechanical work while lowering temperature, the expanded fluid being later on an expander that performs mechanical work while further lowering its temperature, so that the thermal fluid of work at very low temperature performs the thermal sink function of the thermal machine that makes up the secondary module.
    [0028]
    [0029] The thermal machine of the secondary module absorbs heat from the high-temperature thermal source and transfers heat to the thermal sump by increasing the working fluid temperature of the primary module formed by cycle Bl, which passes to the suction of the compressor through the collector exchanger of residual heat of low temperature located in the suction of the compressor, thus closing the cycle thermal cycle Bl. As for the secondary module, it operates by absorbing heat from the high temperature thermal source, performing mechanical work and transferring heat to the cold source or thermal sink.

    [0036]
    [0037] - Electric motor (1) for driving the compressor (2) of cycle Bl.
    [0038]

    [0047] - Electric motor (1) for driving the compressor (2) of cycle Bl.
    [0048] - Compressor (2) (rotary or alternative).
    [0049] - Expander (3) (turbo-expander if it is rotary or cylinder-expander if it is alternative.
    [0050] - Heat exchanger (4) which acts as a high temperature thermal source to the thermal machine of the secondary module (30).
    [0051] - Heat exchanger (5) that acts as a thermal sink or cooler of the thermal machine of the secondary module (30).
    [0052] - Electric generator (6) coupled to the thermal machine of the secondary module (30). - Heat exchanger (7) of external contribution of residual heat of low temperature. - Heat exchanger (8) for external high temperature heat input.

    [0056]
    [0057] This thermal source of heat, by thermally feeding the secondary module (30), yields heat that converts into mechanical work while lowering the temperature of the working fluid, passing it to the expander (3), where it expands with performing mechanical work while lowering even more its temperature, so that the thermal fluid of work at very low temperature absorbs heat from the thermal sump or heat exchanger (5), which is rejected or evacuated by the thermal machine that forms the secondary module (30). The working thermal fluid leaves the heat sink (5) sucked by the compressor (2), capturing low temperature heat through the heat exchanger (7), thus closing the thermal cycle Bl that forms the primary module of the combined cycle .
