Definitions
- This invention is designed to provide information on a device for warming heating liquids at low pressure, or with a closed expansion vessel, specially applicable to heating systems or others of a similar kind, including steam, industrial, therapeutic, household systems etc.
- the devices for warming liquids for heating used at present obtain heat by means of different systems, based on direct heating through electrical resistance and through directly or indirectly emitting generated heat by burning solid and gaseous liquids, hydrocarbon, alcohol, coal, wood, propane, natural gas, butane, household network fuel etc.
- the modern systems used at present usually show features of sensitive mechanical complication, a high purchase cost and maintenance and some of them require sensitive, exact and specialised maintenance and most of them emit a high volume of contaminating pollution into the environment due to not being able to be closed off, an issue which makes installation difficult and expensive.
- the device of this invention is designed to obtain a means of warming liquid for heating and similar uses, providing the advantage of certain very reduced dimensions, with low consumption and high energy performance, devoid of direct fumes from contaminating gases, and without producing waste, also providing the feature of obtaining fast warming of the liquid and providing some almost non-existent maintenance requirements, its installation being extremely simple and economical due to the boiler being closed and not emitting any kind of polluting fuel gas, nor does it consume any oxygen in the area where it is installed.
- the device object of this invention is based on the principal of electro-magnetic induction in order to produce an immediate transfer of energy, low loss and a fast supply of heat to the liquid to be heated, providing a very compact set of elements and submitted to complex controls of the particular working parameters.
- the device of this invention could be very widely applied, the following may be mentioned as examples: heating in general, both household and industrial, application to industrial and household steam generators, the water supply of sanitary hot water, producing cold water, air conditioning etc.
- the device is comprised of means for generating power, a flow chamber and heating the liquid of the magnetic short-circuit kind, means of control and protection and an induction assemblage.
- the fluid to be heated is placed in the inner coaxial pre-heating and flow guide chamber, which forms part of the coaxial body of the device, provided with various chambers depending on its intended use, by means of a circulation or acceleration pump; producing pre-heating and being driven when leaving this prior stage against the parabolic reflection wall of the chamber, where after the molecules have been bounced they are driven by the heating circuit assisted by the pump, receiving the action from the inductor circuit which produces the electromagnetic field, having been magnetically short-circuited by the ferric coaxial chamber, causing the liquid being circulated to be heated by induction.
- a circulation or acceleration pump producing pre-heating and being driven when leaving this prior stage against the parabolic reflection wall of the chamber, where after the molecules have been bounced they are driven by the heating circuit assisted by the pump, receiving the action from the inductor circuit which produces the electromagnetic field, having been magnetically short-circuited by the ferric coaxial chamber, causing the liquid being circulated to be heated by induction.
- the device is controlled by a unit comprising a microprocessor of 4 bits which monitors the room temperature, the temperature inside the heating chamber, the range of the duty cycle, also containing means to control the minimum level, pressure of the liquid and control of the maximum temperature of the fluid for the integral safety system of the equipment.
- the device is mainly used for operations at low pressure, it may also be used for operating with liquid at a certain pressure, in which case it would include a safety valve.
- Figure 1 shows a general diagram of the device object of this invention.
- Figure 2 shows a longitudinal section, likewise a diagram, of the flow and heating chamber.
- the device comprises a resonant flow and heating chamber, indicated in a general manner by "1”, which is provided with a heating chamber "2”, and an outer inductor "3", attached to a circuit of which only the inlet of the liquid has been shown "4" and the way out "5", where the liquid passes by means of a circulation or acceleration pump "6" to the outlet "7", the heat regulators of the heating system or, in general, the harnessing circuit of the heated fluid being placed between the terminals "4" and "7".
- Such circuit is completed by means an expansion chamber "8” provided with a level detector "9".
- a field generator "10”, of a square wave, is designed to feed the power circuit which in turn feeds the inductor "3", performing the control of the whole device by means of a control unit "11" containing a microprocessor which co-ordinates the functions of the whole device and which receives the relevant information regarding temperature, pressure and level, by means of specific detectors and sensors for each function; thermostatic samples of the atmosphere “12", and on the temperature of the boiler by means of a thermostat "13".
- the chamber also contains safety elements such as a safety valve "18" and a klixon "19".
- the device object of this invention is able to produce fast heating of the circulating fluid and control all the functions and parameters of the system.
