Description

  The present invention relates to snow melting system snow melting in a heat insulating foundation building.

  In buildings such as houses in cold regions such as Hokkaido, especially during the winter, snow is piled up on the outdoor concrete soil provided adjacent to the building due to falling snow or falling snow from the roof. There is a risk of accidents such as obstructing traffic or slipping and falling due to freezing.

  In view of the above problems, the present invention provides a snow melting system that can eliminate snow accumulation and freezing between outdoor concrete soil adjacent to a building, and that can be realized effectively and at a low running cost. The issue is to provide.

  In the building having a foundation as a heat insulation foundation, a heat exchanger for thawing snow is embedded in an outdoor soil concrete adjacent to the heat insulation foundation, and the floor is surrounded by the heat insulation foundation. By a snow-melting system in a heat-insulated foundation building, wherein a heat-absorbing heat exchanger is provided, and heat under the floor is transmitted to the outdoor soil concrete through the heat-absorbing heat exchanger and the heat-dissipating heat exchanger. Solved.

  That is, in a heat-insulated foundation building, since the foundation is composed of a heat-insulating foundation, there is no need to insulate between the living space on the first floor and the underfloor space, so the floor under the indoor heating in winter is as warm as indoors. . The snow melting system of the present invention effectively uses the heat under the floor in the heat insulation foundation building and transfers the heat between the outdoor concrete soil adjacent to the building by the heat exchanger. Can be effectively eliminated.

  In particular, heat-dissipating heat exchangers for melting snow are embedded in concrete between the soil, and the concrete-soil is kept warm for a long time due to the heat storage effect of the concrete. Combined with the fact that it is still warm from the beginning of the morning to the dawn, it is possible to maintain the concrete soil between the warm soil without snow and freezing, even in the cold morning, due to their heat storage action, to realize effective snow melting it can.

  In addition, the above-mentioned snow melting system uses warm heat under the floor, which is thrown away by natural heat dissipation from midnight to dawn, and uses it to melt snow using the heat storage action of soil concrete, so it is the most difficult cold morning Snow and freezing between concrete soils can be prevented at a low running cost.

  In addition, the snow melting system of the present invention is intended for outdoor soil concrete adjacent to the heat insulating foundation, and therefore can efficiently transfer heat from under the floor to the heat exchanger for heat radiation in the soil concrete and for heat dissipation. The piping to the heat exchanger can be shortened and the initial cost can be reduced.

  Furthermore, since the heat exchanger for heat radiation is embedded in the soil concrete, the heat exchanger for heat radiation can be firmly protected by the soil concrete, and it can withstand large loads as well as stepping pressure, A snow melting system with excellent durability can be realized, and it is not necessary to secure an installation space for installing a heat exchanger for cooling. Also, especially when you are going to construct new soil concrete in the future, it is sufficient to set the heat exchanger for heat dissipation before hitting the soil concrete, and then drive in the concrete. It can be performed together with the concrete construction, and an efficient construction can be performed.

  When the base under the floor surrounded by the heat insulating foundation is made of concrete soil, the heat storage action can more reliably maintain the supply of heat to the heat exchanger for heat dissipation from night to dawn. At the same time, the cold under the floor can be suppressed, and the interior can be kept warm.

  When the outdoor concrete soil is made of soil near the entrance, morning commuting, attending school, and housework can be started comfortably and smoothly without suffering from snow and freezing.

  In addition, the above-mentioned problem is basically that in a building having a foundation as a heat insulating foundation, a heat storage effect is applied to the soil concrete below the upper surface between the outdoor concrete soil adjacent to the heat insulating foundation. A heat-dissipating heat exchanger is provided in an embedded state, and a heat-absorbing heat exchanger is provided under the floor surrounded by a heat-insulating foundation, and the heat below the floor passes through the outdoor soil through the heat-absorbing heat exchanger and the heat-dissipating heat exchanger. It is solved by a snowmelt system in a heat-insulated foundation building, characterized in that it is transmitted to concrete.

  In other words, the heat exchanger for heat dissipation does not necessarily need to be embedded in outdoor soil concrete, and the main point is that the heat storage effect is exerted on the soil concrete below the upper surface of the concrete soil so as not to obstruct the passage. What is necessary is just to be prepared in the embedded state.

  Since the snow melting system of the present invention is as described above, it is possible to eliminate snow accumulation and freezing between the outdoor concrete soil adjacent to the building, and it can be realized effectively and at a low running cost. .

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  In the snow melting system of the embodiment shown in FIG. 1, 1 is a building, and its foundation 2 is made of a cloth foundation, and a heat insulating material 3 that also serves as a formwork for placing foundation concrete on both sides of the rising portion 2 a. , 3 are provided and are configured as a heat insulating foundation. In addition, the heat insulation base which installed the heat insulating material in any at least one surface may not be used as a formwork. The base 4 under the floor surrounded by the heat insulating foundation 2 is made of concrete.

  An outdoor concrete soil space 5 is formed so as to be adjacent to the heat insulating foundation 2 in the building 1, and a heat-dissipating heat exchanger 6 for melting snow is provided in an embedded state in the soil concrete 5 a. In addition, an endothermic heat exchanger 7 is installed in the space 9 under the floor surrounded by the heat insulating foundation 2. Both heat exchangers 6 and 7 are connected by a pipe 8, and the pump P is driven to The heat exchanging medium is made to go back and forth between the heat exchangers 6 and 7, so that the heat of the underfloor space portion 9 is transferred to the outdoor soil concrete through the heat absorbing heat exchanger 7 and the heat radiating heat exchanger 6. It is made to be transmitted to 5a.

  In addition, in this embodiment, the case where the outdoor concrete soil 5 is between entrance soils is assumed, However, Concrete soils, such as a roofless terrace, near a doorway, an adjacent parking lot, and a dog run, may be sufficient.

  In the above-mentioned snow melting system, the foundation 2 is a heat insulating foundation, so that the space between the living space 10 on the first floor and the underfloor space 9 is not insulated. For example, it is as warm as 20 ° C. Moreover, since the base 4 under the floor is made of concrete soil, the heat of the underfloor space is also stored in the soil concrete 4a. Therefore, by driving the pump P, the heat of the underfloor space 9 and the underfloor concrete soil 4 is transmitted to the outdoor soil concrete 5a and stored, regardless of whether it is morning or afternoon, and the outdoor concrete soil 5 is kept warm. Thus, it is possible to prevent snow accumulation and freezing on the outdoor concrete soil 5.

  In particular, in the heat insulation foundation building, the floor under the floor is kept warm regardless of whether the indoor heating is effective from midnight to dawn, and the base 4 under the floor is a concrete soil with a heat storage function. Combined with the fact that the concrete 5a also has a heat storage function, it is possible to keep the outdoor concrete soil 5 warm from dawn to morning using the heat under the floor. It can be maintained in a warm soil free from snow and freezing, and snow and freezing to the soil 5 can be effectively prevented and running costs can be reduced.

  Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above-described embodiment, the case where the heat-absorbing heat exchanger 7 is installed in the underfloor space 9 is shown, but it may be provided in an embedded state in the soil concrete 4a of the underfloor base. Moreover, there is no restriction | limiting in the kind of heat exchanger to be used, For example, a heat pipe etc. may be used.

It is a section side view of the building which shows the snow melting system of an embodiment.
