Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic lightning extinguishing method for removing snowfall and effectively utilizing snowfall while minimizing energy consumption. The details are as follows.

If there is snowfall (1), the snowfall detector or snowfall detector (2) picks up on it and sends a signal A to the regulator (3). A signal B appropriate for melting the snowfall (1) flows from the regulator (8), which activates the refrigerator (4). The heat dissipation pipe (8) of this refrigerator (4) is connected to the heat dissipation plate (
9), and this is connected to C → heat radiation piping section (lO
) → D The heat of the heat dissipating fluid is released by the heat dissipating plate (9) and melts the snowfall (1). On the other hand, the heat absorption pipe (5) of the refrigerator (4) is guided into a cold storage container (7) filled with a freezing liquid (6), and when the refrigerator (4) is operated, this freezing liquid (
6) is cooled. If you use a freezing liquid that has a transformation point close to the ambient temperature of the place where the cold storage container (7) is installed, and cause the freezing liquid to undergo a state change by absorbing heat, the cold air will leak into the area. The shape of the cold storage container (7) can also be made smaller. When using this method, the lightning extinguishing system according to the present invention functions to extinguish snowfall while creating ice, and removes snowfall ([). What's more, that cold air is a cold storage container (
7) Move inside. In other words, the cold air from snowfall (, 1) is stored in a fixed location without mechanical transportation. Snowfall sometimes causes severe damage to society. However, from another perspective, this is also a valuable low-temperature source provided by nature. Even if you remove snow from an area, you want to avoid spreading it around to catch the cold air.

We also want to keep the amount of energy used to remove snow as small as possible. The present invention is proposed as a method that satisfies both of these requirements, and its advantages are listed in Section F.

1) The heat radiation amount of a refrigerator (cow) is the sum of the Joule heat generated by operating the machine and the transport heat transferred from the heat absorption side, and its heat radiation efficiency η-Q/W Q: Energy flowing to the heat radiation side W: The energy used to operate the machine can be greater than l. Moreover, the lower the temperature on the heat radiation side, the more the transported heat increases, and the higher the heat radiation efficiency becomes. Therefore, the refrigerator (4) can only be used when the heat sink (9) receives snowfall.
) is activated, snowfall (1) can be melted and removed with very little energy consumption.

+1) Since most of the cold air from the removed snowfall is stored again in the cold storage container (7), the low heat source provided by nature as snowfall will not be dissipated. If this stored cold air is used during the summer season, the actual amount of energy required to remove snowfall can be further reduced. In the end, it will be possible to generate new effective energy by sequentially utilizing snowfall and solar heat.

ii) If the frozen liquid (6) in the cold storage container (7) is used near its transformation point temperature, cold air is stored as latent heat of state change, so the cold storage container (7) 2 can be made smaller;
There is no need for particularly large-scale equipment, and it can be installed in each household.

■) As the refrigerator (4), a normal refrigerator using a refrigerant and a compressor or one using a thermoelectric semiconductor can be considered.
Even when it is used, it is easy to control, and an automatic lightning extinguishing mechanism can be set up without using any special device 2.

Methods to automatically control this lightning extinguishing device include an open loop method that operates a snowfall amount detector every moment, and an open loop method that detects the amount of snow on the heat sink (9) and controls the chiller (4). A closed-loop system in which lightning is activated can be considered, but these can be appropriately adopted depending on the conditions of the place where lightning is to be extinguished. Examples of configurations of lightning extinguishing devices using these control methods are shown in block diagrams in FIGS. 2(a) and 2(b).

As described above, according to the present invention, snowfall can be automatically removed with small energy consumption, and the cold air of the snowfall can be stored without being dissipated. It depends on whether you get 2 long-term effects or not.
