and is provided.

In the heat pump device 51, the medium circulation piping 59
is provided.

The medium circulation pipe 59 passes through the first heat exchanger 52 and returns to the first heat exchanger 52 again via a turbine 60, a second heat exchanger 61, and a pump 62 when viewed from the offshore.

The output shaft 63 of the turbine 60 is connected to a generator 64 or a refrigerator pump 65.

A groundwater suction pipe 67 and a groundwater discharge pipe 68 having a pump 66 are provided in the cooling water reservoir of the second heat exchanger 61.

Note that low-temperature water in the first heat storage tank 3 may be used as the cooling water.

That is, as shown by the dotted line, the other of the heat storage tank 3 and the second
A low temperature water supply pipe 69 is provided between the heat exchanger 61 and a low temperature water recovery pipe 70 between the second heat exchanger 61 and the second hot water discharge pipe 56.

Reference numeral 71 indicates a pump installed in the low temperature water supply pipe 69.

In the heating equipment configured as described above, the basic flow of water on the first heat storage tank 3 side is as follows.

That is, the low-temperature water from the other downstream side of the first heat storage tank 3 is pumped out by the pump 34 and supplied to the lower end of each pipe 7 through the low-temperature water discharge pipe 36.

The water then enters the heated object flow space 15 of the lowermost solar heat collection tile 11 through the water supply socket 18, flows through the polystyrene continuous foam 16, and then flows into the pipe 7 through the discharge socket 19 again.

At this time, it flows up one step through the filling 10.

Then, it flows through the round solar heat collecting tiles 11 in the second stage from the bottom in the same manner as described above.

As this process is repeated, the water gradually rises and is heated at the solar heat collecting tile 11, thereby turning into hot water and flowing into the hot water collecting tank 5.

The hot water in the hot water collection tank 5 is lowered through the hot water supply pipe 6 and is supplied to one of the first heat storage tanks 3.

At this time, the pump 32 is being driven, and therefore, by operating the faucet 33, hot water near the one side is sucked into the hot water outlet pipe 30 and taken out to the hot water supply pipe 31. Hot water is optional.

The hot water in the first heat storage tank 3 flows from one side to the other within the open foam body 16, but due to its nature, the hot water does not flow back.
Therefore, the temperature drop line during the flow from one side to the other is warm and straight without disturbance.

When the amount of hot water pooled in the first heat storage tank 3 decreases, the water level meter 48 detects and detects this, and water is replenished F via the tap water supply pipe 38 and the water replenishment pipe 3T. .

In addition, during rainy weather, rainwater collected in the rain gutter 21 is transferred to the water collection pipe 22.
, is pooled in the water storage tank 20 via the filter 23, and this is used as replenishment water? used.

Further, at night, the water inside the solar heat collection tiles 11 can be recovered by backflow.

Absorption of solar heat in the solar heat collecting tile 11 is performed as follows.

That is, in the normal state shown in FIGS. 5 and 6, a uniform gap 17, that is, an air layer, is formed between the two wall bodies 13 and 14.

In this state, solar heat A1 heats the second wall 14, and then heats the first wall 13 due to convection heat transfer in the air layer.

In addition, water B from the water supply socket 18 is supplied to the heated object flow space 1
5, during which it absorbs the heat of the first wall 13, and is discharged from the discharge socket 19 as hot water b1.

In this way, normal heat transfer C1 takes place under normal conditions.

FIG. 7 shows a state where it is receiving high solar heat A2.

According to this, the second wall 14 thermally expands and descends, and the gap 1
7 is reduced so that more parts are in contact with the first wall body 13.

Therefore, the heat transfer C2 is carried out directly at a high temperature, so that high-temperature water b2 can be obtained.

FIG. 8 shows a state in which low temperature water B2 is being supplied.

According to this, the first wall 13 heat-shrinks and rises, and the gap 1
7 is reduced to bring more parts into contact with the second wall body 14.

Therefore, the heat transfer C2 must be carried out directly and at a high temperature, so that a high temperature water b2 can be obtained.

To summarize the above, Figure 6 shows the solar heat at room temperature and the supplied water at room temperature (normal temperature - normal water), and Figure 7 shows the case where the solar heat is high and the supplied water is at room temperature (high temperature - normal water). Figure 8 shows a case where the solar heat is at room temperature and the supplied water is at a low temperature (normal temperature - low water).

In any of these cases, there is a difference in heat transfer - directional heat transfer.

Looking at another form, in [room temperature and high water] the state shown in Figure 6,
[High temperature and high water] the state shown in Figure 7, [High temperature and low water] the state that combines Figures 7 and 8, [Low temperature and constant water], [
In the cases of [low temperature and high water] and [low temperature and low water], the deformed state shown in FIG. 6 in which the gap 17 increases is obtained, and in both cases, heat transfer occurs in one direction.

The open polystyrene foam 16 also elastically deforms in accordance with the thermal deformation of the second wall 14.

As mentioned above, water B supplied from the water supply socket 18
,,B2 are discharged from the drain socket 19 as hot water b,,b2, but because they flow through the polystyrene continuous foam 16 in the heated object flow space 15, due to their nature, the water b1 is , b2 does not occur, and therefore the temperature rise line from the inlet to the outlet can be maintained undisturbed.

Further, when external pressure acts on the second wall 14, the gap 17
The second wall 14 is only deformed to reduce the external pressure, and this external pressure is applied to the open polystyrene foam 1 through the first wall 13.
It can be caught on the 6th side.

In FIGS. 1 and 2, when household garbage is incinerated in the garbage incinerator 42, the regulating valve 45 is operated and the pump 46 is activated.

Then, the hot water near one side of the first heat storage tank 3 flows into the hot water recovery pipe 4.
3 and then supplied to the lower part of the heating chamber of the garbage incinerator 42.

The supplied hot water is further heated by waste incineration heat, becomes high-temperature water, and is taken out to the high-temperature water take-out pipe 44 and supplied to one side of the second heat storage tank 4.

The remainder of the high temperature water pooled in the second heat storage tank 4 is taken out from the other side through the second hot water discharge pipe 56 and then
The hot water from the hot water supply pipe 6 flows through the hot water discharge pipe 55 .

The high-temperature water pooled in the second heat storage tank 4 is sucked into a high-temperature water take-out pipe 49 disposed near one side by driving the pump 54, and taken out to the high-temperature water supply pipe 50.
After being used for heat exchange in the first heat exchanger 52, it is returned to the first heat storage tank 3 side via the first hot water discharge pipe 55.

The medium heated in the first heat exchanger 52 drives the turbine 60, is cooled in the second heat exchanger 61, and then returns to the first heat exchanger.
Return to heat exchanger 52.

Note that the generator 64 is rotated by the drive of the turbine 6ro,
This provides household electricity.

Alternatively, cooling can be made possible by rotating the refrigerator pump 65.

Although the garbage incinerator 42 is shown as a heating device, it may be a heavy oil furnace or the like.

Alternatively, high-temperature water for household use may be taken out from the second heat storage tank 4.
