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.

Document WO 2008/125875 A2 discloses (the following reference signs applying to this document) an autonomous electrically stimulated radiator (10) configured to be used for heating purposes inside buildings, comprising:
    • an electronic processing unit (part of 32 which doesn't control power: see below);

    wherein the autonomous electrically simulated radiator is configured to generate heat when current generated by the power unit and determined by the electronic processing unit flows;
    and wherein the priority controller (p.20-21) is configured to receive from a facility panel-board (since it can receive information from a plurality of radiators, it can receive information from a facility panel-board when the right signal is transmitted) information concerning power consumption of other appliances in the facility (p.20-21). 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 a radiator according to claim 1.

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 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 nnwer
  • 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.
