本発明は消雪効果を高めた屋根雪の消雪方法お
よび装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for removing snow from roofs with enhanced snow removal effects.
屋根上の積雪による建物の損傷または破壊を防
止するために雪おろし等が豪雪地帯では不可欠で
あり、この雪おろし雪の始末に多大の労力を要し
ているのが現状である。また高所屋根や大面積屋
根（工場や駅舎など）では、人力では雪おろしに
限界があることもある。 In order to prevent damage or destruction of buildings due to snow accumulation on roofs, snow removal is essential in areas with heavy snowfall, and the current situation is that a great deal of effort is required to remove and dispose of the snow. Additionally, there may be limits to how much snow can be removed manually from high-placed roofs or large-area roofs (factories, station buildings, etc.).
この屋根上の積雪に対し、近年融雪設備が相当

各家屋に取付けたりしている。 In recent years, snow melting equipment has become widely used to deal with this accumulation of snow on roofs. For example, panel heating equipment and hot water spraying equipment are installed on high-pitched roofs and large-area roofs, and equipment for spraying groundwater, river water, or city water is installed in each house.

た。地下水、河川水または市水の如き通常の水を
使用した消雪の場合は、使用量を増加しなければ
効果をあげることができない。 However, in the case of hot water spraying, even if heat insulation measures are taken on the roof side, the amount of heat that is effectively used for snow removal is normally only 10 to 20% of the amount of heat held by the hot water. The remaining 80 to 90% of the heat is due to contact with low-temperature, humid air, which absorbs the sensible and latent heat of the hot water. Of these, sensible heat loss and latent heat loss can be considered to be approximately the same, and sensible heat loss
40-45%, latent heat loss is 40-45%. Therefore, conventional snow removal by spraying hot water is extremely inefficient and results in a large loss of thermal energy. Snow removal using ordinary water such as groundwater, river water, or city water cannot be effective unless the amount used is increased.

ものである。 The present invention has been made with the aim of solving these problems, and provides a method and method for removing snow from roofs that can greatly enhance the snow removal effect, reduce water consumption, and suppress latent heat loss economically. It provides equipment. That is, the present invention provides a method for dissolving snow accumulation or snowfall on a roof by spraying or spreading water or hot water on the roof surface,
A substance containing oxyethylene docosanol having the general formula C22H45O ( CH2CH2O )nH, where n is an integer of 1 to 2 , is added to the water or hot water. An amount sufficient to form a monomolecular film of oxyethylene docosanol is added to the surface of hot water that comes in contact with the outside air, and the melted snow water flowing down from the roof after snow removal treatment is collected and reused again. Alternatively, it is characterized by being recycled and used as hot water.

が試みられている。 Oxyethylene docosanol (usually OED) used in the method of the present invention is a known substance. This substance has a hydrophobic group (higher alcohol) and a hydrophilic group (ethylene oxide) at the end of the molecule, so when it is contained in water, the hydrophilic group is directed inward on the water surface. It has the property of forming a coherent film (monolayer). For this reason, this OED has been used as a water droplet life extension agent in artificial fog generation experiments, and in recent years, attempts have been made to use it to promote rooting and improve quality in agriculture, horticulture, forestry, etc.

とがわかつた。 The present invention has achieved results by applying the properties of this OED to roof snow removal. According to experiments conducted by the present inventors, an OED film is instantaneously formed on the surface of water droplets not only at low water temperatures but also at hot water temperatures of 40 to 50°C, suppressing water evaporation even when exposed to low temperature and low humidity outside air. virtually no latent heat loss,
In addition, it was confirmed that even in a continuous water film flow, an OED film is always formed on the surface of the water film that comes into contact with the atmosphere, and that latent heat loss from the continuous water film surface can be substantially avoided. The present invention
Utilizing the phenomenon that a monomolecular film of this OED is constantly formed not only on still water surfaces but also on the surface of flying droplets and running water films, hot water containing this OED is sprayed onto the snow on the roof, and it is also cast onto the roof surface. This makes it possible to substantially avoid this latent heat loss of hot water. The snow melting water itself generated when this OED-added warm water comes into contact with snow is also collected, and the melted snow water, which is a mixture of this OED-added water and snow melting water, is recirculated as hot water for snow melting. If used, the excellent snow removal effect can be maintained semi-permanently without deterioration of the OED's function, and the loss of OED can be reduced.In addition, the increased amount of water due to melting snow can be drained outside the system. Considering the runoff water, it was found that the total amount was small, and the required amount of OED addition was extremely small.

の場合の外部熱源の軽減ができる。 The amount of OED added is sufficient to cover the water surface exposed to the outside air on or outside the roof with a monomolecular film of OED. OED monolayer is approximately 3.2m
Since the thickness of the OED is 100 μm, the required amount of OED added varies depending on the size of the water droplet and the casting thickness, but normally it is sufficient to add an extremely small amount of about 1/10,000, for example, 5 tons in total. The system that uses 500g of circulating water
By adding a certain amount of OED, sufficient latent heat loss can be prevented, resulting in a nearly 90% evaporation suppression effect. In other words, in the case of no OED addition, about 90% of the heat that would be taken away from the outside air due to latent heat loss is used for snow melting, increasing the snow melting effect.
Moreover, the evaporation of the snow melting water itself used for snow removal from the surface is suppressed, and the recovered heat is also increased, making it possible to reduce the external heat source when hot water is used.
