Next, the operation of the hot spring steam power generation / hot water production system 1 according to this embodiment will be described.

In the hot spring steam power generation / hot water making system 1 according to this embodiment,
(1) Hot spring steam flows in from the flow path piping section 3.

(2) By inflowing hot spring steam, the temperature inside the thermoelectric conversion / cooling unit 11 becomes high (about 100 ° C.).

(3) That is, the inner surface of the thermoelectric conversion element unit 14 (thermomodicol) installed in the thermoelectric conversion / cooling unit 11 becomes high temperature (about 100 ° C.).

(4) Further, the outer surface side of the heat sink 16 which is the cooling element unit 17 outside the thermoelectric conversion element unit 14 is cooled by the cooling tower fan 18, which causes a temperature difference (Δt) on both sides of the thermoelectric conversion element unit 14. ..

For example, if the outside air temperature is 30 ° C., a temperature difference of Δt = 70 ° C. occurs due to forced cooling.

(5) Due to this temperature difference (Δt), a current starts to flow in the thermoelectric conversion element unit 14 and power generation based on hot spring steam is started (the amount of power generation [electric power: voltage and current] increases or decreases depending on the value of Δt). ..

Also be utilized as a similarly hot spring water in the case of this prior art is discharged downward from the manufacturing hot (hot spring water) and made the hot water discharge pipe system 4 is simultaneously vapor thermoelectric conversion and cooling unit 11 is cooled ..

(6) Since hot spring steam is ejected without interruption, the steam is not shown, but unless stopped by a valve, the inside of the thermoelectric conversion / cooling unit 11 is kept at a constant high temperature, and the outside of the thermoelectric conversion element unit 14 is a cooling tower fan. It is cooled by air cooling by 76 (or vaporization heat by mist-like liquid spray, or water cooling), but the temperature difference (Δt) varies depending on the cooling capacity.

(7) Here, temperature control inside and outside the thermoelectric conversion / cooling unit 11 is required. A temperature sensor that monitors the inside / outside of the thermoelectric conversion / cooling unit 11 is installed and monitored in this device, and the monitoring information is provided. Is configured to be fed back to the control / measurement unit 21 to control the cooling function of the cooling tower fan 76 and the like. As a result, a constant temperature difference (Δt) is always maintained to enable stable power supply.

(8) The electric power generated by the thermoelectric conversion / cooling unit 11 is DC electric power, but the generated DC electric power is converted into the same single-phase AC 100V AC electric power as the commercial power source by the AC power supply unit 23. This AC power can be used for general lighting equipment and home appliances.

(9) Of course, it is also possible to install a power storage function in order to maintain more stable power generation.

Next, the power generation capacity of the hot spring steam power generation / hot water production system 1 according to this embodiment will be referred to.

The power generation capacity of the hot spring steam power generation / hot water production system 1 of this embodiment depends on the temperature difference (Δt) between the inside and outside of the thermoelectric conversion element unit 14 and its installation area.

The outer cooling mechanism is important to maintain the most efficient temperature difference (Δt), but this depends on the temperature, flow rate, etc. of the hot spring steam, such as natural air cooling, forced air cooling, mist spray cooling, and water cooling. The optimum cooling method can be selected from the cooling methods such as.

When the temperature difference Δt is 70 ° C., the standard power generation capacity is 10500Wh (10.5kWh) at 36V direct current (DC) and 100V single-phase AC via the AC power supply unit 23 in the size of a general cooling tower. A maximum of about 9000 Wh (9 kWh) is possible, but it depends on the temperature difference (Δt), the size (power generation area), and the like.
