Description
AUTONOMOUS ELECTRICALLY STIMULATED RADIATOR
DESCRIPTION
This invention refers to autonomous electric radiators used to heat the interior of buildings.
Autonomous electrical radiators are available in the market and operate using electrically heated wires, which heat a liquid e.g. synthetic oil, or ceramics with high heat capacity, or take use the heat generated when alternative current flows through streams of a liquid.
The main drawbacks of those heating systems are the following: the increased time required to reach the desirable temperature; the inability to regulate the operational electric load so as to simultaneously operate with other energy-consuming appliances; and the inability to simultaneously manage and control the energy supplied to more than one electric radiator.
Autonomous electric radiators taking advantage of. the heat generated when alternative current flows through streams of a liquid comprise a metal cylinder connected to the neutral conductor and an electrode connected to the current phase inside the cylinder.
The cylinder and electrode are made of cast iron or other conducting material and there is electrical insulation at their point of contact.
When the liquid flows through the cylinder, the electric current passes through and heats it.
The cylinder and electrode dimensions are standard and determine the apparatus electric output based on the electrode's contact area with the water or with the glycol-water mixture in the radiator.
The fact that the electrode surface is fixed is a drawback for such systems because electrical conductivity varies and is dependent on the existence of ions, the concentration, migration speed and valence thereof and on temperature variation; this results in the system not having a fixed capacity.
In case of current leakage, the cylinder is hazardous as no protective grounding has been provided for.

Patent 1008030 and the Patent Amendment with application number 20130100706 submitted by the same applicant form part of the present invention improving the efficiency, operational safety and the cost of manufacturing of the autonomous electrically stimulated radiator.
The purpose of this invention is to create an autonomous electrically stimulated radiator as per the above, which will be more efficient, safer and less costly to manufacture by reducing the time required to achieve operational temperature,
ensuring self-regulation of the operational electrical load required when used simultaneously with other power-consuming devices, and making it possible to also work with other relevant electrically stimulated radiators for the purpose of optimally adjusting the temperature and the power output in complex areas.
According to the invention, this is achieved with the use of metal plates internally adjusted on a plastic core connected to the phase (single-phase) or phases of current (three-phase). The plastic core contains the neutral conductor, which is made of steel and comprises a solid cylindrical bar surrounded by the circuit liquid. The water inside the core is heated by the electricity flowing through it and comes out by natural recirculation on the higher layers of the radiator through holes on the core surface.
The electrically stimulated radiator takes advantage of the heat that is rapidly generated when alternating current flows through streams of liquid. This heat is diffused in the surrounding area.
Self-regulation of the operational electrical load required when the autonomous electrically stimulated radiator is used simultaneously with other electric devices, is achieved by using the power unit, a priority controller and the electronic processing unit. ^
The priority controller comprises a microcontroller. Given the microcontroller is a standardised product widely used in built-in systems such as in automation and electronic products, its design features and operation are not analysed. It performs the following function: based on the power required by the remaining appliances in the facility, it first distributes power to such appliances and then to the autonomous electrically stimulated radiator. In essence, the microcontroller receives from the facility panel-board the information concerning the power consumption, converts it into digital information and transfers it to the processing unit which uses its respective software in order to send a command to the power unit to reduce the power supplied to the radiator.
The power unit comprises a microcontroller and an electronic power switch (solid state relay SSR or TRIAC), which are standardised products widely used in built-in systems such as in automation and electronic products and their design features and operations are not analysed. The power unit performs the following function: it receives commands from the electronic processing unit and distributes the electric power to the circuit.
If other power-consuming electric devices are turned on, the power unit reduces the consumption of power.
When used simultaneously with other electrically stimulated radiators, the power unit reduces the power consumed by the electro-stimulation radiator by transmitting electric pulses.
The electric pulses are determined by the electronic processing unit, which prevents concurrency of power consumption by communicating with the respective processing units of the other radiators. Power is in essence supplied to the radiator through the power unit in the form of electrical pulses; electrical stimulation is achieved in the form of electrical pulses, alternations of electric current. Power is intermittently transferred to the electrical circuit via the SSRs. This is a difference as compared to all pre-existing systems transferring electrical power through liquids to produce heat.
In the case of the autonomous electrically stimulated radiator, the power supply is intermittent using the power unit, and controlled by the processing unit.
This invention may communicate with relevant electrically stimulated radiators in the same area or in close proximity by-wire or wirelessly. The purpose of this communication is to provide the user with the possibility to regulate the desirable temperature and the simultaneous power consumption in all areas where autonomous electrically stimulated radiators are installed avoiding concurrency of power consumption.
This invention may be fully understood based on the following analytical description with reference to the attached drawings wherein:
Figure 1 presents the electronic processing unit (1 ); the area (2) and water (7) sensors; the priority controller (3); the power unit (4); the plastic core (6); the curved plates (8); the metal rod (9); the metal neutral spacer (10); and the electrodes sealing and connecting screw (1 1 ). Figure 2 shows a perspective of the plastic core (6), which is made of plastic material in replacement of the cast iron cylinder ensuring insulation and reducing the risk of electric shock as it is not under load.
The electronic processing unit (1 ) comprises a processor, a memory unit wherein the daily operation programme is stored and may also be interconnected to other relevant units in the same area or in close proximity by-wire or wirelessly. The water (7) and area (2) sensors, and the priority controller (3) are connected to the electronic processing unit (1 ).
The electronic processing unit (1 ) determines the operation of the power unit (4) and in essence controls the power used.
The power unit (4) receives control commands from the electronic processing unit (1 ) and distributes power to the circuit.
The power unit (4) reduces the consumption of electric power in the event that other power-consuming electric devices are turned on.
When used simultaneously with other electrically stimulated radiators, the power unit (4) reduces power consumption of the electrically stimulated radiator (5) by transmitting electric pulses. The electrical pulses are determined by the electric processing unit (1 ), which prevents concurrency of power consumption by communicating with the respective processing units of the other radiators.
The electronic processing unit (1) receives the information regarding other electrically stimulated radiators being in use by-wire or wirelessly.
In the event that the power needed for the operation of the electrically stimulated radiators exceeds the one set by the user, then the electronic processing units (1 ) allot the available power proportionately depending on the desirable temperature set by the user in respect of each radiator. The power is allotted by using electric pulses, distributing different periods of the alternating current. The radiator (5) is a product available in the market and it varies depending on the size of the radiator and the heat generated and it may also be interconnected with the remaining parts of this invention.
Inside the radiator (5) along its lower length, is a hole wherein the plastic core is
placed. The radiator contains a network of pipes connected to the plastic core and the water flows through it. Inside the hole the following are adjusted: the plastic core (6) in which the curved metal plates (8) are placed; the electrodes sealing and connecting screw (11) holding the plates together; and the metal rod (9) which is fixed with the use of the metal neutral spacer ( 0).
