Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat source system having a vertical temperature distribution, which is particularly used in various water heaters.

(Prior art and its problems) It is well known that various types of boilers are normally used as a heat source for hot water supply systems, but these boilers usually have a vertical temperature distribution structure. Therefore, as the water circulates within the boiler and exchanges heat, it is gradually heated according to this vertical temperature distribution.

Therefore, in a conventional water heater, when trying to obtain high temperature hot water, medium temperature hot water, and low temperature hot water individually, for example, hot water is heated gradually from low to medium to high according to the vertical temperature distribution. is obtained from the corresponding part of the supply line via a faucet or the like.

However, in the past, the water supply side and the hot water supply side of the water heater were constructed using the same pipeline, so this was not a problem when obtaining high temperature hot water, but it was necessary to deal with medium temperature or low temperature water. This would result in a considerable loss of heat if it were to be obtained from a section of the supply line that
There has been a major problem in terms of heat loss in that hot water at the desired temperature cannot be obtained in the high-temperature portions of the pipeline, but hot water at the desired temperature cannot be obtained in the medium-temperature portions.

Accordingly, one object of the present invention is to provide a heat source system having a vertical temperature distribution that can appropriately provide hot water at a desired temperature without affecting the hot water supply temperature in other temperature distribution parts at all. It is.

Means for Solving the Problems In order to achieve the above object, the present invention provides a heating section that independently utilizes the vertical temperature distribution of a heat source, and a heating section for discharging heat from the heating section. A vertical temperature distribution structure in which a plurality of unit bodies each having an independent heat absorption part to which heat is transmitted is molded, and the plurality of unit bodies are arranged vertically in accordance with the vertical temperature distribution of the heat source. The present invention aims to provide a heat source system having the following.

Furthermore, in addition to this configuration, the present invention also provides a heat source system having a vertical temperature distribution in which a plurality of units are detachably connected.

(Function) Therefore, in the present invention, unlike conventional heat source systems, the water supply line and the hot water supply line are not constituted by the same pipe line, but heating that utilizes the vertical temperature distribution of the heat source individually. If a plurality of unit bodies each consisting of a section and an independent endothermic section to which heat is transferred only from the heating section are arranged vertically in accordance with the vertical temperature distribution of the heat source, each unit body Hot water at a desired temperature corresponding to the temperature distribution can be easily obtained.

Moreover, since each unit is independent, it does not affect the hot water supply temperature in other temperature distribution areas at all. This means that a medium temperature section can be provided reliably.

(Embodiments) Below, the present invention will be described in detail based on each embodiment illustrating the present invention. As shown in FIG. Two first unit bodies U1 and a second unit body U2 are formed, each of which includes heating parts 2A and 5A that are used independently, and heat absorption parts 2B and 5B to which heat is transferred only from the heating parts 2A and 5A. do,
A configuration is adopted in which the two unit bodies U1 and U2 are vertically arranged in accordance with the vertical temperature distribution of the boiler 1.

The first unit body U1 utilizes the combustion chamber itself of the boiler 1 for its own heating section 2A, while
By arranging a heat absorption pipe having a water supply port 3 and a hot water supply port 4 in a spiral shape in the combustion chamber A, a heat absorption section 2B to which heat is transferred only from the heating section 2A is configured.
The structure is such that low-temperature hot water is supplied from a hot water supply port 3.

In addition, the second unit body U2 uses the chimney of the boiler 1 as its own heating section 5A, and also spirally arranges an endothermic pipe having a water supply port 6 and a hot water supply lower around the chimney, which is the heating section 5A. By arranging it, a heat absorbing part 5B is configured to which heat is transferred only from the heating part 5A, and high temperature hot water is supplied from the hot water supply lower of the heat absorbing part 5B. still,
Regarding the second unit body U2, in order to prevent heat radiation, a heat storage chamber structure is formed between the heating section 5A and its own inner wall.

Furthermore, in this embodiment, each of the unit bodies U1 and U2
When connecting the upper and lower parts, as shown in the figure, a flange part 8 is formed at the connecting edge of each unit body U1, U2, and the opposing flange parts 8, 8 are connected to each other via a screw member (not shown) or the like. By removably connecting the unit body U1
・U2 shall be installed in series.

Therefore, with this attachment/detachment structure, in the first embodiment,
Increase or decrease the unit body with independent heating section and heat absorption section,
The units can be easily rearranged.

Therefore, in the heat source system of the first embodiment, unlike conventional heat source systems, the water supply line and the hot water supply line are not configured in the same pipe line, but the vertical temperature distribution of the heat source can be used independently. The 2al unit bodies U1 and U2, which are composed of heating parts 2A and 5A, and independent heat absorption parts 2B and 5B to which heat is transferred only from the heating parts, are arranged vertically according to the vertical temperature distribution of the heat source. If they are arranged in series in the same direction, hot water of a desired temperature corresponding to the temperature distribution can be easily obtained from the hot water supply ports 4 and 7 of each unit body U and U2.

Moreover, since the unit bodies U1 and U2 are each independent, they do not affect the hot water supply temperature in other temperature distribution areas at all. This means that a medium-temperature section can be provided reliably.

Next, the heat source system according to the second embodiment will be explained.
As shown in FIG. 2, the second embodiment is based on the structure of the first embodiment, and a third unit body U3 described below is also attached to the lower part of the first unit body U1 with a flange portion 8 and a screw member. The other configurations, functions, and effects are completely the same as those of the first embodiment.

However, the third unit body U3 does not have any heating section that independently utilizes the vertical temperature distribution of the boiler 1, and uses its own heat source such as solar or heat pump, although not specifically shown. Accordingly, a configuration is adopted in which water circulating in the heat absorption pipe 9 disposed inside the unit body U3 is heated to a low temperature.

Therefore, in the second embodiment, the third unit body U3, which does not have a heating part that utilizes the vertical temperature distribution of the boiler 1, is intended to supply low-temperature hot water, and the first unit body U1 is placed in a medium-temperature part. By using the second unit body U2 as a high-temperature hot water supply, it is possible to independently provide hot water at a desired temperature from each of the unit bodies U1, U2, and U3.

As described above, the present invention provides a unit body comprising a heating section that independently utilizes the vertical temperature distribution of a heat source, and an independent heat absorption section to which heat is transferred only from the heating section. It is characterized by molding a plurality of unit bodies and connecting them vertically according to the vertical temperature distribution of the heat source. The hot water supply line is not configured with the same pipe line, but instead consists of a heating section that independently utilizes the vertical temperature distribution of the heat source, and an independent heat absorption section to which heat is transferred only from the heating section. If these unit bodies are arranged vertically in a row according to the vertical temperature distribution of the heat source, each unit body can provide the desired temperature distribution corresponding to the temperature distribution without affecting the hot water supply temperature in other temperature distribution areas. This means that you can easily obtain warm hot water.

Furthermore, if the units are connected in a detachable manner, the number of units can be easily increased or decreased, and the units can be easily rearranged, making it possible to improve and expand the system itself.
