FR2805033A1 - Centralized water production system uses a thermodynamic generator in parallel with a classical heat generator - Google Patents

Abstract

System uses a thermodynamic generator (1), two heat exchangers (2,3) and valves (4-6). The system is fed by a generator and does produce hot water alternatively with a classical heat generator (8).

Description

The proposed invention consists of 1) producing energy in the form of hot water and ice water from one or more reversible thermodynamic power plants associated with one or more typical conventional generators; cogenerable boiler, electric boiler, steam generator, incinerator, etc ...

2) To recover energy from seawater, river, lake or from an underground aquifer.

3) To allow a backup operation of the thermodynamic power plant by adding a generator set 21.

This group can also operate as an energy supplement The installation is composed of: - a water-water thermodynamic power plant, landmark 1, - 2 heat exchangers, landmarks 2 and 3 on the loop circuit (upstream and downstream), - 3 valves 3 control channels and inversion of the control unit 1 - Marks 4, 5 and 6, - a generator 7, - a reference generator 8, - a 3-way control valve and priority 9, - 2 circulating circulation pumps hot and cold water production markers <B> 10 </ B> and 11, -a circulation pump loop mark 12, - 2 well pumps marks 13 and 14, or a surface water drawing pump 15, - of a set of automatic 2-way valves, on wells circuit marks from 16 to 24.

This invention is particularly suitable for the production of energy whose basic source is electricity. Electrical pricing, particularly in FRMICE, is based on a system whose price varies according to the periods of the year, the days and the hours of use. The proposed invention allows, among others, to use at any time the cheapest and most suitable source of energy, to transfer these sources, to rescue them from each other to optimize a @ -nsi energy production whose base is thermodynamic central water-water reversible.

The process is particularly suitable for the production of energy applied to installations using bass such as heating and air conditioning and water as heat transfer fluid for <B> TOC </ B> varying between +5 and '+ 88 C in general, corresponding to outside temperatures of -10 C to +35 C.

Application heating air conditioning with gas boilers + generator The thermodynamic unit supplies all hot and cold needs up to a so-called equilibrium temperature (TQj in principle close to +5 C. Outside, during this period, hot water is distributed between 35 and 55 C and chilled water between +3 and +12 C depending on the type of emitter used.When the outdoor TC drops below the equilibrium temperature, the boilers provide the additional hot energy needed, a variable temperature of 50 to 80 C.

The operation is of the proportional simultaneous type. During this sequence of operation, the cold requirements are always provided by the thermodynamic power station - even T C. High electrical tariff called Peak During the peak period of the tariff, 90% of the energy is still provided by the PAC but from the generators and not by the electricity network. The rest, 60%, being provided by the boilers. This allows to have, during this period, about 30% of the total cold energy and to provide a minimum need for ice water These periods are generally in winter, periods during which cold needs are limited. In case of failure or accidental insufficiency, boilers may at any time substitute for the Thermodynamic unit.

5 Principle of operation Energy recovery from surface water (sea, lake, river) The water is captured at the surface or depth of the water table either by a surface pump or by a submerged pump, after filtration. This water is directed towards the exchanger marker 3, and yields or absorbs calories according to the needs of the thermodynamic power plant.A second exchanger marker 2 makes it possible to constitute a loop in closed circuit via the pump 12.

The Thermodynamic unit constantly generates heat through its condenser and chilled water by its evaporator. The equilibrium is obtained either by the evacuation of the excess energy by the exchanger 2, or by the regulation of the reference valves 4, 5 and 6 to mix <I> the 2 </ I> fluids (hot and cold) ) and therefore, to completely balance the production, to remove the primary water ocrrpage by stopping the pump 15, as well as the loop by stopping the pump 12. This regulation is used only when the equilibrium between hot and cold needs is reached, or close to being, ie in off-season during the months of April, May and September October.

The thermodynamic unit supplies hot water at a variable temperature ranging from 35 to 6C depending on the refrigerant used. However, for the profitability of the installation, a 50V is considered as a reference value. Beyond this value, when the water CT is insufficient to satisfy the needs, the generator 8 provides the energy supplement by unlocking the valve 9. The operation is simultaneous, central thermodynamic + generator with simultaneous production of cold . During periods with high electricity tariffs (peaks), the electric power supply is cut off and the thermodynamic power station is powered by the generator set. The thermal energy of the group, cooling and co # rbustion, is recovered and transferred to the hot water circuit in -décorte condenser.

Beyond this, it is advisable to stop the thermodynamic production or to evacuate the calories towards the heat exchanger.

<B> Energy recovery in groundwater </ B> The energy production remains unchanged until the secondary heat exchanger 3, only the recovery is concerned by this chapter, from the primary of the heat exchanger 3 and instead of surface water recovery. The energy recovered from one or more aquifer boreholes may alternatively be used for capture or discharge. Each one is equipped with a pump allowing the cleaning with rejection with the sewer invention relates to the manifold of reversibility which allows the game of the valves 16 to 24 and with a single piping of connection, to select automatically - either the pumping, - or the rejection, - either washing, each drilling.

method, from a simple clock program, allows to ensure, cyclically for example, all the aforementioned functions automatically and unattended.

process is particularly suitable for drilling made in cracked rocks, limestone chalk.
