Definitions
- the present invention relates to a boiler that can supply a heating system with hot water of a building while simultaneously producing domestic hot water within the same unit.
- the subject of the invention is a boiler with anti-chamber and helical exchanger which makes it possible to perform the tasks mentioned above.
- hot water heating systems are powered by electric boilers, oil or gas.
- the heat diffusion inside the building to be heated in this way can be carried out with several types of fan-coil equipment, cast iron radiator, finned tube or floor heating manifold.
- the circulation of hot water inside the building is in closed circuit using a circulating pump, hence the term “boiler” rather than “water heater”, the latter system, by definition, heating water for external use and not for a closed circuit.
- the boilers provide the power necessary for the production of domestic hot water either by the use of indirect water heaters like the one marketed under the brand OPTIMIZER / TURBOMAX, or by adding a "tankless" type coil inside the boiler.
- the combination boiler and indirect water heater is interesting because it allows to produce large amount of hot water and thus meet residential, commercial and institutional needs.
- the boiler acts as a source of energy and the indirect water heater as a heat exchanger.
- the exchange coil contains heating water and the tank contains domestic water.
- the coil contains domestic water, and the tank contains the heating water.
- the OPTIMIZER system mentioned above.
- this type of installation requires the purchase of two separate equipment.
- the present invention relates to a boiler for supplying heating water to a heating system of a building and for simultaneously producing domestic hot water.
- This boiler is characterized in that it comprises:
- a heating body provided with an inlet and an outlet for the heating water
- an anti-chamber attached to the heating body, this anti-chamber being in communication with the heating body and containing means for heating the heating water; and - A heat exchanger provided with an inlet and an outlet for the domestic water, this exchanger being composed of several spiral-shaped coils disposed in the heating body so as to allow a transfer of energy between the water in the heating body and the domestic water circulating in the coils.
- the heating water inlets and outlets of the heating body are provided with injectors designed to (i) inject a portion of the water to heat in the anti-chamber in order to create a turbulence and ensure a heat transfer from the anti-chamber to the heating body, (ii) ensure uniform distribution of the heating water in the heating element and (iii) cause turbulence of the heating water around the heating elements. coils;
- the exchanger extends over almost the entire height of the heating body to extract a maximum of energy by heat transfer
- the anti-chamber is disposed in a lower part of the heating body to enjoy a natural convection within said heating body.
- the subject of the invention is thus a boiler that allows both the heating of a building and the production of high speed instant domestic hot water within a single appliance.
- This boiler comprises a heating body which is provided with an antechamber and is filled with low pressure heating water.
- a low-pressure circuit provided with a circulating pump makes it possible to feed diffusion equipment of a building by circulating the heating water between the heating body and the diffusion equipment of the building which can be constituted by a fan.
- -convector fan-coils
- a cast iron radiator a finned tube or a heated floor tubing.
- the production of domestic hot water is ensured by the transfer of energy between the water of heating the heating body and a heat exchanger consisting of several spiral-shaped copper coils arranged to withdraw 100% of the energy of the heating body.
- Heating means also referred to hereinafter as "energy source”, are installed inside the anti-chamber of the heating body. These heating means are chosen to have the power necessary to meet the demand for water heating and domestic water.
- the heating body Since the heating body is always filled with closed circuit heating water, there is no corrosion inside this heating body. Indeed, after a few hours, the oxygen contained in the heating water at the start is purged and this non-oxygenated water remains in the system year after year without corroding the heating element, thus ensuring a long life of the heater. 'apparatus.
- the heating water inlets and outlets in the boiler heating body are provided with injectors such as those covered by Canadian patent no. 2038520. This allows a uniform diffusion of the heating water inside the heating body when the circulating pump is in operation, causing a turbulence of the heating water around the coils, the injectors promote heat exchange while eliminating stagnant areas or cold passages of heating water that would normally accumulate.
- heating water inside the heating body keeps the efficiency of the device over time unlike traditional water heater or boilers used as a "booster". Indeed, the heating water does not contain sediment and limestone unlike domestic water. Thus, there is no deposition of scale on the outer walls of the heat exchanger and the hot surfaces of the energy source (electrical elements, burner, gas exchangers) unlike traditional systems. Since the scale acts as an insulator and heat transfer process, the efficiency of the system according to the invention should therefore be superior to traditional systems over time.
- the heat exchanger for the transfer of energy for the production of domestic hot water is composed of several copper coils. This avoids any problem of corrosion with domestic water, because the copper has a life of more than 50 years.
- the heat exchanger advantageously has a shape and an arrangement for extracting the maximum energy of the thermal mass of the heating body.
- this exchanger is composed of several helical coils which are advantageously arranged in a compact and circular manner to allow the energy to be withdrawn throughout the cylinder of the heating body.
- the exchanger extends over the entire height of the heating body and is provided with a domestic cold water inlet which is located in the lower part of the heating body and a domestic hot water outlet of the exchanger which is located in the upper part of the heating body.
- the helicoidal shape of the copper coil has the advantage of promoting the turbulence of the domestic water inside the copper coil. This increases the heat exchange between the heating water and the domestic water and decreases scale build up inside the coil.
- the helical shape of the coil also allows a contraction in expansion of the material radially which also reduces the scale buildup.
- the energy source required to provide the power required to meet the heating demand is present in the anti-chamber of the heater.
- This anti-chamber is an annex to the heating body that communicates the energy via the openings of the cylinder of the heating body.
- This anti-chamber is actually in the lower part of the heating body.
- the energy of the anti-chamber is transmitted to the heating body through openings when the circulating pump is in operation, or by natural convection. This creates turbulence and ensures heat transfer from the anti-chamber to the heater.
- the anti-chamber is positioned on the lower side of the heating body allows, when the circulating pump is stopped, to provide a natural convection inside the heating body, as well as a baseboard heating under a window. This natural convection ensures a more even temperature between the bottom and top of the heater when the pump is off and the power source is on, unlike the traditional water heater.
- the energy source can be of several types: electric, oil, gas or solar.
- the boiler according to the invention may be accompanied by a bypass path for circulating the heating water between the top and the bottom of the boiler.
- a bypass path for circulating the heating water between the top and the bottom of the boiler.
- the boiler's heating body according to the invention could be used for another purpose, namely to store energy to release it when the energy costs vary according to the period of use. the day.
- the energy could be stored by water or other phase-change equipment.
- Figure 1 is an open perspective view of a boiler with antechamber and helical exchanger according to a preferred embodiment of the invention
- FIGS 2, 3 and 4 are respectively views from above, front and side of the boiler illustrated in Figure 1;
- FIGS 5 and 6 are views similar to those of Figures 2 and 4, wherein the basic structural elements of the boiler are identified by numbers;
