Abstract

Autonomous furniture tempering system urban.

The system is based on establishing in a urban furniture one or more radiation circuits (12) by circulating or fluid conveniently tempered to radiate constant temperature to users, so that this furniture urban (6) has integrated a secondary circuit with one-way branch (7) and return branch (8) of the fluid, coming from a inter-accumulator (1) accessed by the fluid from an energy source that may be formed by solar panels (2) or even a heat pump geo-thermal (15), establishing the primary circuit (3), in which an exchanger is established geo-thermal (5) for dissipation of excess heat in the contribution of the fluid.

Description

Autonomous furniture tempering system urban.

Object of the invention

The present invention relates to a system of autonomous tempered of street furniture, whose obvious purpose is to temper the elements of street furniture such as benches, canopies, swings, playgrounds, etc., using for this alternative and / or conventional renewable energies for Minimize resource consumption.

The object of the invention is to temper the street furniture so that the sensations of hardness, coldness, impersonality, etc., become pleasant sensations and warm, inviting even the use and enjoyment of street furniture, and all without energy consumption, or with the minimum possible, when resorting to alternative energy means or renewable as a preferred way of feeding the system.

Background of the invention

At present, street furniture lacks something more than its own utility and sometimes a high content of intrinsic design, which is sometimes hard to understand, by it is unknown the existence of systems that aim to lead to out a tempered street furniture.

However, and as an antecedent of the invention, the Spanish Utility Model U 200800747 can be cited, in which a regulation and safety equipment is described for solar thermal energy installations, which deals with a single surrounding circuit and that is planned to determine the cut of fluid that circulates through an installation in case a desired working temperature, in order to prevent overheating of the installation and overpressure formation therein, said equipment being associated with a set of plates solar, integrated aeration grilles for heating the fluid circulating inside them, and an exchanger of heat for heating the water that accesses to it through corresponding tubes.

In said Utility Model, it is not established no system that allows tempering street furniture.

Description of the invention

The system that is recommended, applicable to a multitude of furniture, called urban, is based on establish in the furniture itself one or more circuits of radiation through which a fluid recirculates conveniently tempered, being able to radiate that constant temperature to users, so that the tempered fluid and therefore the furniture radiation circuits are established based on a primary circuit through which the heated fluid circulates through solar panels, and whose primary circuit is established a solar heat exchanger for heat dissipation, of so that demand is supplied through this primary circuit of an inter-accumulator depending on what you need or it is wanted, so that said inter-accumulator, to through a secondary circuit of tempered fluid that transfers, through recirculation pumps, mixing valves, to the furniture that is intended to temper.

The system changes significantly when it comes geothermal collection since the heat and cold circuits are reduce to one and a heat pump, keeping the rest of the system in the same way.

Accordingly, according to the invention, the system take advantage of the energy collection of external media through the sun, light, geothermal, water, air, etc., so that through a exchanger and accumulator, this energy is produced and stored at Waiting to be sued for street furniture or other nature activity or similar application.

The way the energy will be arranged, mainly from renewable and clean media, such as previously said, according to the invention is based on tempering a fluid or mixture of them, of high degree of freezing and high thermal transmission power, which is recirculated by several internal circuits located in the furniture you want to temper, to transmit the potential of heat or cold to that furniture, and therefore get your tempering, getting a feeling nice and warm that invite even the use of 1 own furniture.

Obviously, the system may be structured on the basis of one or several mono-shaped circuits or bitube, and with a high transmission power such as steel stainless.

It is also expected that in areas or places of street furniture that do not want to be tempered in their parts or elements, to avoid thermal leakage, will be available protections that isolate said circuits totally or partially, thereby reducing thermal losses where they are not needed, thereby extending the battery life and therefore the consumption of the energy spent.

In addition to the features and advantages previously referred to, the system in its application to furniture urban results with significant improvements among which you can quote:

-

Is a maximum efficiency system in its purpose and with a consumption minimum.

-

Is a simple implementation system, easy to install and great effectiveness.

-

Is a system that provides self-sufficiency, hence it is autonomous, With minimal maintenance.

-

Is a system that solves the emissions issue of the Treaty of Kyoto

-

Is a modular and autonomous system, since it can be applied to a multitude of modules and with an appropriate distribution or arrangement of these within an area or place.

Description of the drawings

To complement the description that then it will be done and in order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof, is accompanied as an integral part of that description, a set of drawings in where illustrative and not limiting, it has been represented the next:

Preferred Embodiment of the Invention

As you can see in the referred figures, the system of the invention first comprises a inter-accumulator (1) of a tempered fluid that It has a high degree of freezing and high transmission power thermal, so that the fluid is heated by plates thermal solar (2) so that, through a primary circuit (3) and recirculation valves (4), the fluid reaches the inter-accumulator (1), forming part of that circuit primary (3) a geothermal exchanger (5) as a device power sink and cold application.

The fluid tempered through the inter-accumulator (1) is sent to urban elements or modules (6) through a secondary circuit with a one-way branch (7) and a return branch (8), existing in that circuit secondary
(7-8) a thermostatic mixing valve (9) and a recirculation pump (10) of the same characteristics as the valve (4) in the primary circuit (3). A fluid bed (11) is provided in the inter-accumulator (1).

Based on the referred characteristics, the fluid that reaches the inter-accumulator (1) through of the secondary circuit (7-8) performs a continuous recirculation, by means of the recirculation pump (10) a a pre-set temperature, of what is orders said thermo-static mixing valve (9), which mixes fluids at different temperatures to that the circuit presents the temperature pre-set

The fluid at the temperature pre-established and constant is circulated by one or more circuits established in furniture (6) to temper, which behave like simple emitters, because they, that is inside, circulate the tempered fluid.

Figure 3 shows specifically a furniture or bench-shaped furniture (6) with a plurality of radiating circuits or chambers (12) for the tempered fluid, with the branch or one way circuit (7) and with the branch or return circuit (8), the system as a whole including a trap (13).

To avoid unnecessary energy losses and therefore increase system performance, can be isolated those areas of street furniture that makes no sense tempering, such as driving or so-called as non-radiant, being able to see in figure 4, which corresponds to a sectional section of the furniture (6) represented in figure 3, the radiant zones or chambers (12) complemented with isolated zones (14) in the manner described above.

Figure 2 shows the system in which the solar thermal panels (2) have been replaced by a pump of geo-thermal heat (15), so that in the circuit in which that heat pump is established geo-thermal (15) an expansion vessel is planned (16), a cooling pump (17), a balancing valve (18), a flow regulator (19), stopcocks, etc.

The commented primary circuit (3) may be fed only with geo-thermal energy and with its balanced to the demand of the inter-accumulator (1), ruling a simple heat pump geo-thermal
