Abstract
The invention is an operating logic that, through the use of already known elements connected according to the diagram enclosed hereto, resolves a series of anomalous operating situations known to the experts in the art, thus optimizing the yield of biomass heat generators (water-powered). In particular, the biomass generator is capable of providing performance levels that can be compared to those of a traditional generator, using a small-sized storage system. This is possible thanks to the introduction of the mixing valve (V4) in the return circuit of the biomass generator, which will keep conveying cold water into the generator independently of the need for hot water, thus making the generator work longer at minimum power avoiding repeated switching cycles or overheating.
Description
THERMAL ENERGY DISTRIBUTION KIT OR SYSTEM FOR THE PRODUCTION OF DOMESTIC HOT WATER AND HOT WATER FOR HEATING PURPOSES AND SYSTEM EMPLOYING SAID KIT
DESCRIPTION
FIELD OF THE INVENTION
This patent relates to hydraulic systems for the distribution of thermal energy, and in particular it is based on a kit or system for the distribution of thermal energy for the production of hot water/heating from generators, in particular biomass generators. PRIOR ART
There are commercially available stoves and boilers of the so-called water heating type, designed for the production of process hot water that are used to heat water for domestic purposes and for heating.
There are known biomass powered boilers and stoves of the water heating type in the known art, usually powered by pellets and used for the production of hot water for domestic purposes or, alternatively, for the production of hot water for heating purposes.
The known art comprises kits installable on water heating boilers or stoves and suitable for the distribution of the thermal energy alternatively to the heating system or to the domestic hot water system.
The stoves for this purpose must have a high power output, greater than or equal to 20 KW.
However, these distribution systems have some operational disadvantages, in particular due to the need to adapt to the discontinuous operation of the stove to which they are connected during construction.
In fact, a certain amount of time is required after the start up of the stove before it is able to provide hot water for domestic or heating purposes. Therefore, the user will not have hot water available for a certain period of time, especially if the heating system needs to be run at full power at the same time.
In particular, the normal use of domestic hot water is not possible with the boiler/stove switched off, or in the shutdown phase, or in the 15 to 20 minutes after the boiler/stove is switched on.
Currently, due to the substantially discontinuous operation of pellet water stoves, the availability of hot water is also discontinuous.
To resolve this problem, at least partially, the kits of the prior art must have a high volume process/domestic hot water storage tank to cope with the usage needs with the drawback of the increased footprint necessary.
These kits must therefore be installed in specially dedicated areas of the home, such as a boiler room, garage or other area.
INTRODUCTION TO THE INVENTION
To overcome all of the aforementioned drawbacks, a new type of thermal energy distribution kit has been developed and constructed using known components for the production of domestic hot water and heating, for generators, particularly a biomass water heating type stove or boiler, and system using that kit.
The main task of the present invention is to ensure continuity in the production of hot water while using a discontinuous generator such as a biomass water heating stove or boiler.
Another object of the present invention is to guarantee this continuity even with generators with power outputs below 20 KW.
Another object of the present invention is to maximize the efficiency of the stove/boiler and minimize consumption, since the working time is extended to its maximum when the generator power is set to its minimum, reducing the number of times the generator is switched on and off over the course of a day.
Another purpose is to avoid the continuous intervention of the stove's regulation system and prevent the over-temperatures that occur in systems of the known art which cause operating problems with the biomass generator.
The main object is to be able to extend the operation of the biomass generators at their minimum, by controlling combustion, both in the heating phase and during the
production of hot water, by acting on the temperature of the return water going to the generator. By maintaining the return temperature as constant as possible and below certain limit values, it is possible to control the operating logic of the generator and make it operate in a gradual and linear manner. This, as noted above, reduces the number of times it is switched on/off, as well as the fuel and electrical consumption, since the number of generator start ups is limited. On the other hand, the generator's performance and its life time are also maximized, since it is subject to less stress. The present invention is also designed to have a smaller storage tank than that used in systems of the prior art. In this manner it can be integrated into a single unit with the generator and be used to power a low/high temperature radiant system. This, in turn, can be integrated into the generator's single unit, and also used to for heating purposes.
An advantage of the present invention is that it can be installed in existing systems with biomass water heating type stove or boiler generators, possibly replacing traditional boilers, or by running the biomass generator alongside other existing generators.
Another advantage of the new invention is that it can be easily installed without complex interventions.
These and other, direct and complementary goals are achieved by the new thermal energy distribution kit for the production of domestic hot water and heating, for generators, in particular a biomass water heating type stove or boiler, and a system utilizing this kit.
DESCRIPTION OF THE INVENTION
The new kit comprises:
- at least one buffer or storage tank of process water from the stove or generator in general;
- at least one coil housed in the storage tank for the production of hot water to be sent to the domestic hot water system and for heat exchange with the process water;
- at least one initial heat exchanger, for example a plate type, able to exchange heat between the hot process water from the stove or generator in general and the fluid of the heating system;
and wherein that storage tank and that at least one initial heat exchanger can be connected in parallel with the water heating stove or generator, preferably biomass, such that the hot process water from the generator is sent to the storage tank and/or heat exchanger according to the needs.
In particular, the new kit comprises at least one main circuit for the circulation of hot process water comprising a delivery duct from the stove or generator to the storage tank and a return duct from the storage tank to the stove or generator.
The kit also includes at least one secondary circuit to circulate hot process water, comprising at least one duct, to divert part of the hot process water from the delivery duct to the at least one exchanger, and at least one recirculation duct of the outgoing process water from the at least one exchanger to the return duct to the generator.
The new kit also comprises at least one electronic control unit connected to one or more temperature sensors and one or more valves to control the delivery of hot water to the at least one storage tank and the at least one exchanger according to the load requirements.
Further, the control unit may also evaluate the water temperature difference between delivery and return in order to control the operation of the stove or generator.
The new kit may also include at least one low/high temperature radiant system, comprising a line to draw water from the storage tank, the circulation in a radiant means such as a radiator or radiant panel, and recirculation in the return duct to the stove or generator.
By means of this radiant system it is therefore possible to obtain at least two advantages:
1) the water temperature in the return duct to the stove or generator is lowered further, ensuring the extension and operation of the stove or generator itself at least at their minimum output;
2) the unused heat of the process water contained in the storage tank is partially used for heating purposes.
This radiant means can be integrated into a single body with the stove or generator which, especially if it can be installed internally as a decorative object, also serves to heat the environment in which it is located.
One or more additional thermal exchange coils may be installed in the storage tank for other functions.
OPERATION OF THE INVENTION
To explain the operation of the new kit, it is necessary to individually evaluate some of the various possible operating conditions.
A) stove/generator start up phase
During the start up phase, the control unit controls one or more valves so as to give priority to the exchanger of the heating system. In other words, the hot process water from the generator is sent to the exchanger. The hot water for the heating system is then quickly made available since the exchanger exchanges directly with the hot water from the stove.
Thus the heating circuit takes heat from the exchanger, decreasing the temperature of the output water from the exchanger itself.
In this condition, and in the absence of a demand for hot water, it is possible that in the return duct only the water coming from the heat exchanger is supplied by means of a thermostatic valve which gives priority to the water from the exchanger, which is colder, and closes the side communicating with the storage tank.
This is due to the fact that the valve is thermostatic and set at a certain return water temperature, adjusted by the operator.
Therefore, since the return water to the generator is cold, the generator works at maximum power to meet the demand for heating.
B) minimum load phase
When the demand from the heating system begins to decrease, the water temperature in the return duct increases, so the generator begins to modulate the power until it reaches the minimum power.
As the temperature of the water exiting the exchanger increases, the return fluid to the generator is mixed with the water from the cold storage point of the storage tank by means of the thermostatic valve, which is activated to maintain the decreased temperature of the process water returning to the generator.
In this way, the temperature of the water returning to the generator is lowered to keep the generator power to a minimum, avoiding overheating and thus blocking the generator. The minimum power output is used to heat the water that is sent in part to the exchanger and in part to the storage tank from which it returns through the return duct to the generator.
This situation continues as long as the circuit of the heating system requires heat, after which the generator will be switched off, transferring any excess thermal energy toward the storage tank.
In systems of the known art, however, the generator, working at the minimum, still works at a power greater than that required by the heating system, with the risk of overheating and the subsequent safety shutdown of the generator itself.
C) demand for hot water phase
The generator turns on and, when it reaches the established temperature, starts the pump to circulate the hot water which will go to the exchanger and towards the storage tank. In the case of demand for domestic hot water, the water leaving the storage tank is sent directly to the generator, bypassing the mixing valve which would limit the flow.
The generator then begins to work at maximum power to ensure the production of hot domestic water by means of the coil in the storage tank.
Using a suitable technological control of the system, when the appropriately dimensioned storage tank has sufficient thermal energy accumulated to ensure the production of domestic hot water, the system modifies the route of the circuit: the
water exits the generator and is conveyed to the exchanger where there is no heat exchange, since there is no demand from the heating system, and then returns to the generator. This route causes an increase in the temperature of the return water flowing to the generator, which therefore lowers the operating power to a minimum.
The minimum power of the generator is used to charge the storage tank up to its maximum level, ultimately causing the generator to be switched off.
The new kit with storage tank can be integrated into a single body with the biomass water heating stove or generator, or it can be installed in its own containment body, with approximate dimensions of 60 x 55 x 165.
The system comprises this kit and at least one biomass generator equipped with stoves or boilers of the water heating type.
The new kit can be installed onboard standard biomass-pellet stoves/boilers, with combustion control.
The new kit improves systems of the prior art since it does not use motorized three- way mixing valves with multiple control probes, but a simple manual and adjustable thermostatic mixing valve, mounted in series with the exchanger on the return duct to the generator.
In this way, using a mixing valve and a by-pass diverting valve, the new kit takes advantage of the control system already installed in the biomass generators of the known art, which have their own logics and modulate the power as a function of the temperatures set for the delivery and return circuits.
Given that they are solid fuel generators, they have a slow modulation in order to burn the material in the most efficient way in the combustion chamber.
The main purpose of the mixing valve mounted on the new kit is to allow the water to return to the generator at a maximum temperature, for example 60°C, which is higher than the value set in the generator. In this way the generator detects the return temperature higher than the value set in the generator itself and decreases the power to its minimum.
This allows the storage tank to be thermally charged over a longer period of time, thus reducing the start up/shutdown "swings" of the generator (G).
Thus the electronic control unit has the task of controlling the temperature of the storage tank in the different operational phases and, if there is a demand for domestic hot water, it operates on a bypass diverter valve through which the storage tank water is conveyed directly to the generator, without being mixed with the hot water coming from the exchanger, resulting in an increase in the generator's power output.
Thanks to the new kit, the user can optimize the operation of the generator.

The characteristics of the new kit and the new system will be better explained by the following description with reference to the drawings attached by way of non-limiting example.
Figure 1 shows a diagram of the new system or kit (1), while Figure 2 is a representation of a possible embodiment of the new plant comprising a biomass water stove or generator (G) equipped with the kit (1) and a radiant panel (62).
DESCRIPTION OF A PREFERRED EMBODIMENT
This is a new thermal energy distribution kit (1) for the production of domestic hot water, for biomass generators (G) and/or boilers and/or stoves of a water type.
The new kit (1) comprises at least a "buffer" or storage tank (2) of hot water coming from the aforementioned stove or generator (G), and at least one main circuit (20) for the circulation of hot water, in turn comprising a delivery duct (21), from the stove or generator (G) to the storage tank (2), and a return duct (22) from the storage tank (2) to the stove or generator (G).
The new kit (1) also comprises at least one coil (3) housed in the storage tank (2) for the heat exchange between the water contained in the tank (2) and the water intended for domestic use to be conveyed to a domestic hot water system (DHW).
The coil (3) is connected to at least one cold water supply (31) and at least one hot water outlet (32).
The new kit (1) also comprises at least one first heat exchanger (4) suited to exchange heat between the process hot water coming from the stove or generator (G) and the fluid to be conveyed to a heating system (R).
The hot water from the stove or generator (G) is conveyed to the heat exchanger (4) by means of at least one secondary circuit (40), which in turn comprises at least one duct (41) to divert part of the hot water from the delivery duct (21) to the at least one heat exchanger (4) and at least one recirculation duct (42) of the output water from the at least one heat exchanger (4) to the return duct (22) connected to the generator (G).
The storage tank (2) and the at least one first heat exchanger (4) are thus connected in parallel to the stove or generator (G) in such a way that the hot water from the generator (G) is alternately or simultaneously conveyed to the storage tank (2) and the heat exchanger (4) according to the needs.
The operation of the kit (1) is controlled by at least one electronic control unit (5) connected to one or more temperature sensors that detect the temperature in the storage tank (2) and switches/feedback controllers related to the heating plant (R) and with the generator (G).
In particular, the kit (1) comprises at least one mixing valve (V4) downstream from the heat exchanger (4) on the return duct (22) suited to control the inflow of water from the storage tank (2) and from the heat exchanger (4), conveying the water to the generator (G) which may be:
- coming exclusively from the heat exchanger (4);
- obtained by mixing the water coming from the heat exchanger (4) and the storage tank (2).
The new kit (1) also includes at least one by-pass valve (V3) on the return duct (22) used when the water coming from the storage tank (2) must go directly to the generator (G) by-passing the mixing valve (V4).
The electronic control unit (5) thus detects the water temperature in the storage tank (2) and, depending on the water temperature and the demand for domestic hot water or heating by the heating system, opens or closes the by-pass valve (V3).
Optionally, the new kit or system (1) may include one or more heat exchange coils (7) installed in the storage tank (2) and suited to serve other functions or utilities.
A further optional accessory of the new kit or system (1) comprises a radiant system (6) with a water line (61) drawing the water from the storage tank (2) and a circulation line in a radiant means (62) or a radiator or radiant panel or forced air to air heat exchangers and a recirculation line (63) in the return duct (22) to the stove or generator (G), the radiating system (6) being controlled by at least one by-pass valve (V6) depending on the need for heating.
The hydraulic system to supply a water heating system (R) and a domestic hot water system (DHW) using the new kit (1) comprises at least one generator (G) or stove or boiler of the water heating type, either replacing or in addition to a traditional boiler, and where the at least one generator (G) is based on biomass technology.
As shown in Fig. 2, the at least one generator (G) and the at least one kit (1) may be integrated into a single body also containing the at least one storage tank (2) to form a compact body.
According to the invention the radiant means (62) may also be constituted by a radiant panel integrated in a single body with the stove or generator (G), thus also having an aesthetic interior decoration function in addition to providing heating. Therefore, with reference to the preceding description and the attached drawings the following claims are made.
