困難であることが多く、また滑降が可能となるか否かは
、自然ｌＩ１雪の有無や気温等の自然条件に左右され易
く、予測が困難であった。Conventional technology In early winter, when the ski season has just begun, or during warm winters, there is little snow on the slopes, and it is often difficult to ski downhill, and whether or not it will be possible to ski downhill depends on nature. It was difficult to predict as it was easily affected by natural conditions such as the presence or absence of snow and temperature.
そこで、各地のスキー場においては、＠雪不足時に備え
て人工降雪機を設置しているところが多い。For this reason, many ski resorts around the country are installing snowmaking machines in case there is a shortage of snow.

せることができる。In addition, in cases where snowfall is not expected due to lack of snow, an artificial snow machine is used to artificially deposit snow on Slope 1. However, under normal circumstances, even if the temperature drops below freezing and artificial snowfall is possible, the ski slopes will be covered with snow. The surface temperature of the roadbed 2 in No. 1 does not fall below freezing, and even if artificial snow is fallen, it will melt and not be piled up. However, since a large number of heat pipe type roadbed cooling equipment 3 are installed to cool the roadbed 2, It is possible to make artificial snow fall without melting it.

流通するようになっている。On the artificial roadbed 14 of the slope 16, a large number of heat pipe type roadbed cooling equipment 17 are arranged in parallel at approximately equal intervals, and each heat pipe type roadbed cooling equipment 1
The steaming section 17a of No. 7 is an artificial path! It is disposed on the upper surface of the slope 814 from one side of the slope 16 (the left side in FIG. 2) diagonally downward in accordance with the slope, and is buried at a depth that is almost hidden under the surface of the artificial roadbed 14. The condensing section 17b equipped with heat radiation fins of each heat pipe type roadbed cooling fJ] equipment 17 is connected to one side of the slope 16.
The artificial snow layer 15 is formed on the artificial roadbed 14 by an artificial snow machine (not shown), and it is possible to ski down the snow. It looks like this. In addition, this Indoor Ski @ 11 has special special ski w4 equipment (
(not shown) to forcefully circulate low-temperature air with a predetermined degree of leakage, so that the low-temperature air blown from the air conditioning equipment flows through the condensing section 3a of each heat pipe type roadbed cooling equipment 3. It has become.
次に、この実施例の作用を説明する。Next, the operation of this embodiment will be explained.

が冷却される。Inside the indoor ski resort 11, low-temperature air sent out from special air conditioning equipment is forced to circulate. Therefore, the heat pipe type roadbed cooling fA equipment 17 is installed by burying each evaporating part 17a in the upper surface of the artificial roadbed 14 and extending the condensing part 17b above the ground, so that the air is forced to circulate. cools the condensing part 17b and acts as a heat pipe, takes heat from the artificial roadbed 14 around the evaporating part 17a, transports the heat to the condensing part 17b, and releases the carried heat from the condensing part 17b. The vicinity of the surface of the artificial roadbed 14 is cooled.

することなく積って人工雪層１５が形成される。In this way, when the temperature of the air that is forced to circulate indoors is lowered to below freezing, the surface of the artificial roadbed 14 is cooled down to below freezing, near the indoor temperature, by the heat pipe type roadbed cooling equipment @17, so that the artificial snow is cooled down to the artificial roadbed 2. Even if it falls on top, it does not melt and accumulates to form the artificial snow layer 15.

積らせることができる。Therefore, even if the outdoor temperature is high, the indoor temperature is lowered by forcibly circulating sub-zero cold air indoors using special air conditioning equipment, and the artificial roadbed 14 is cooled by the heat pipe type roadbed cooling equipment 17. Therefore, artificial snow can be piled up on slope 16 without melting.
