Description

Electro thermal power generating plant solar.

Object of the utility model

The following Utility Model, as expressed in the statement of this specification, it refers to a electric power generating plant using as a source of Solar thermal energy energy.

The set is designed to take advantage of Effective and large-scale solar thermal energy, generating electricity economically and being able to accumulate thermal energy during the day for release during night hours. He system operation is based a machine that takes advantage of a thermal differential to move a fluid through a turbine and thus generate electricity.

Background of the invention

The principle of solar thermal energy operation which is the means of obtaining energy from the proposed system. Is also known the behavior of refrigerant gases in circuits pressurized In addition in this model the property is also used of the specific heat of water and other elements as an end to accumulate thermal energy This utility model is intended adapt these technologies to take advantage of solar energy thermal to generate electricity, and also to be able to do it in hours Daytime and nighttime.

Description of the invention

The set described consists of a machine thermal formed by a turbine linked to an electric generator. For moving the turbine is necessary to move a fluid through the turbine with certain speed. A gas is chosen as a fluid refrigerant, the Ammonia being ideal. The set has a system that allows to regulate the fluid pressure in the system. To generate the displacement of the fluid there are two Main element: an evaporator and a condenser.

The evaporator is an element responsible for expanding the fluid and thermal energy is provided for this. For this one purpose are arranged a series of solar thermal collectors of classic construction The fluid can be heated directly in the inside the thermal collectors or in a heat exchanger hot.

The set capacitor consists of thermal accumulator and secondary condenser. Heat accumulator It consists of a water tank with radiators inside by which the fluid circulates after passing through the turbine. In this way the fluid yields its residual heat to water. The accumulator cannot condense the fluid once a certain water temperature has been reached. At this time the condenser will come into operation secondary, which consists of a radiator cooled by water, air, or A mixture of both. The secondary condenser can be replaced by a heat exchanger that will use the excess heat to other apps.

The system will reverse the fluid direction to generate electricity at night. In this sense the accumulator will provide thermal energy to the fluid, which will expand and move the turbine. Thermal solar panels may work as capacitors right now, or so can the secondary condenser or heat exchanger.

System layout allows progressive implementation of more solar thermal panels that pour water heat the accumulator. It also allows unlimited expansion of the thermal accumulator. These features allow the operation for more night hours of the turbine. For the purpose of optimize the transfer of energy to the accumulator in hours daytime the system pressure can be increased while in nighttime it is preferable to decrease said pressure. The option of increase or decrease in pressure will be given by the specific demand electric power

Description of a preferred embodiment

As provided in figure number 1, a series of solar thermal collectors 1 collect heat energy which is transported to a heat exchanger 2 by means of a water stream moved by a water pump 3. In the 20 2 heat exchanger is injected ammonia gas which is previously stored in a tank with its own pump regulation 4. The gas expands acquiring a kinetic energy that It is used to move the turbine 5 attached to the generator 6. Once the gas has left the turbine is driven to a series of radiators 7 installed in a tank 8 filled with water and high elements specific heat. Once the water reaches such a high temperature that cannot absorb the residual heat of the gas, it will be cooled in a condenser 9 of a cooling tower 10 and then will return to the circuit.

Another series of solar thermal collectors 11 will provide additional thermal energy to reservoir water 8 which will be circulated in them by a water pump 12.
