  However, in the invention described in Patent Document 1, floor heating is installed on all floors of all the floors of the house, and furthermore, both a winter fan and a summer fan are installed, which increases the cost. End up.

  Accordingly, an object of the present invention is to provide a circulation type air conditioning system that circulates air in a house and adjusts temperature and humidity in a well-balanced manner.

  In order to solve the above-mentioned problems, the present invention connects the house 2 in which the heat insulating materials 3, 3 a, and 3 b are installed, the fan 5 that sucks the air 6 near the ceiling 2 b, and a pipe connected to the fan 5 to the floor 2 k The temperature is adjusted by absorbing or releasing the heat of the air duct 5a piped in the air, the underfloor air duct 5b connected to and branched from the air duct 5a at the underfloor 2k, and the air 6 of the underfloor air duct 5b. A heat storage concrete 4 and an air outlet 2f opened in the floor 2e at a position where the air supply port of the underfloor air blow pipe 5b is provided are provided, and the air 6 in the house 2 is interposed between the fan 5 and the air outlet 2f. It was set as the structure of the circulation type air conditioning system 1 characterized by circulating.

  Since this invention is the above structure, the following effects are acquired. 1stly, even if it does not install air-conditioning equipment in each room, the temperature difference for every room disappears by circulating the air of the whole house, and temperature and humidity can be adjusted efficiently.

  Second, by using a heat insulating material on the wall, ceiling, and floor of the house, a comfortable temperature can be maintained without being affected by outside air. Moreover, the use of air-conditioning equipment can also be suppressed by arranging heat storage concrete under the floor.

  Thirdly, by circulating the air in the whole house including under the floor without stagnation and averaging the temperature, it is possible to suppress the increase in local relative humidity caused by the temperature difference of the air. In addition, the occurrence of fungi such as mold that adversely affect the maintenance of the soundness of the housing structure is reduced.

  The purpose of the present invention is to adjust the temperature and humidity in a well-balanced manner by circulating the air in the house, to the house where the heat insulating material is installed, to the fan that sucks in air near the ceiling, and to the fan by connecting a pipe to the floor A ventilation duct that is vertically piped, an underfloor air duct that is connected to and branched from the air duct under the floor, heat storage concrete that adjusts temperature by absorbing or releasing heat of the air in the underfloor air duct, and This was realized by providing an air outlet opened on the floor where the air supply port of the underfloor air duct is located, and circulating the air in the house between the fan and the air outlet.

  Below, based on an accompanying drawing, the circulation type air-conditioning system which is the present invention is explained in detail. FIG. 1 is a perspective view of a circulation type air conditioning system according to the present invention.

  In the circulation type air-conditioning system 1, the air 6 near the ceiling is sucked by the fan 5 and sent to the underfloor blower pipe 5b disposed under the floor 2k by the ventilation duct 5a vertically piped inside the inner wall 2g and blown out from the air outlet 2f. Thus, the air 6 is circulated to average the temperature of the entire house 2.

  In addition, the thermal storage concrete 4 is laid under the floor 2k so that the temperature change in the house 2 becomes small. That is, when the heat storage concrete 4 absorbs heat when it is hot such as daytime and releases heat when it is cold such as nighttime, the difference between the maximum temperature and the minimum temperature in the house 2 can be reduced.

  Further, a ceiling heat insulating material 3 is installed between the roof 2a and the ceiling 2b, a wall heat insulating material 3a is installed between the outer wall 2j and the inner wall 2g, and an underfloor heat insulating material 3b is installed between the foundation 2i and the heat storage concrete 4, and the house 2 The temperature of the inner air 6 is protected from being affected by the temperature of the outside air.

  FIG. 2 is a sectional view of a circulation type air conditioning system according to the present invention, and FIG. 3 is a sectional view of a conventional house. In addition, about the air conditioning equipment 7a, it is the same also in the case of dehumidification other than heating and air conditioning.

  As shown in FIG. 3, in the conventional house 2, the room 7 is partitioned by a partition 7b such as a wall, and is sealed only by a window 2h, a door, etc., and the temperature of only the room 7 that uses the air conditioning equipment 7a. There are many adjustments, and the temperature difference from other locations is large.

  If the windows 2h and doors are frequently opened and closed, warm air or cold air escapes. If it is going to air-condition all the rooms 7, it is necessary to install the air-conditioning equipment 7a in all the rooms 7, and it is very inefficient in terms of cost.

  In winter, warm air 6 tends to gather near the ceiling 2b in the room 7, and the vicinity of the floor 2e tends to be cold. In particular, the vent 2l is often vacant in the floor 2k, and is easily cooled by the influence of the temperature of the ground 9 and the outside air.

  On the other hand, as shown in FIG. 1 or FIG. 2, the house 2 in which the circulation type air conditioning system 1 is introduced causes the air 6 of all the rooms 7 to flow to the second floor ceiling 2b, and is sucked by the fan 5 and is made by the ventilation duct 5a. The air 6 is circulated by sending to the floor 2k and blowing out from the air outlet 2f opened in the first floor 2e.

  In order to make the air 6 in the room 7 easily go in and out, the airtightness of the partition 7b and the second floor 2c is weakened so that the air 6 on the first floor rises from the air vent 2d to the second floor. The fan 5 is installed at a high position near the second-floor ceiling 2b, and the air 6 is sucked to create a flow of the air 6 from the first floor to the second floor.

  However, the airtightness of the foundation 2i and the outer wall 2j of the house 2 is increased so that the outside air does not easily enter the house 2. Moreover, the ceiling heat insulating material 3, the wall heat insulating material 3a, and the underfloor heat insulating material 3b are installed so that the air 6 in the house 2 is not affected by outside air.

  The ceiling heat insulating material 3, the wall heat insulating material 3a, and the underfloor heat insulating material 3b are heat insulating materials arranged continuously without a gap, and can maintain the temperature in the house 2. In addition, about the underfloor heat insulating material 3b, in order to support a part of load of the thermal storage concrete 4 and the house 2, it is preferable to use a highly foamed raw material.

  A ventilation duct 5 a is connected to the fan 5. The ventilation duct 5a is a pipe in which a pipe extending from the second-floor ceiling 2b to the underfloor 2k passes vertically between the wall heat insulating material 3a and the inner wall 2g, and is connected to the underfloor air blower pipe 5b stretched around the underfloor 2k.

  The underfloor air duct 5b is branched into a plurality at the underfloor 2k, extends to a plurality of rooms 7 or a plurality of locations on the first floor, and corresponds to the position of the air supply port that is the tip of the underfloor air duct 5b. An air outlet 2f is opened in the floor 2e.

  In the present invention, generation of fungi and the like can be suppressed by circulation of the air 6, but a filter may be provided in the fan 5. When the fan 5 is provided with a filter, dust and fungi can be removed from the air 6.

  In the underfloor 2k, heat storage concrete 4 is laid between the underfloor heat insulating material 3b and the underfloor air duct 5b. If the temperature of the air 6 coming out of the underfloor air duct 5b is high, the heat is absorbed and the temperature is increased. If it is low, heat is applied and the temperature is always adjusted to the same level.

  The air 6 having the appropriate temperature is ejected from a plurality of air outlets 2f provided on the first floor 2e, and the temperature of each room 7 is also made uniform. For example, even if the person 8 who was in the room 7 in winter enters the toilet 7c, it does not have to feel cold.

  The air 6 ejected from the air outlet 2f of the first floor 2e causes a flow of air 6 from the first floor to the second floor by suction of the fan 5 near the second floor ceiling 2b. The flow from the fan 5 up to 2k below the floor is made, and the circulation of the air 6 continues.

  Although it was difficult to exchange the air 6 in every corner only by ventilating inside and outside the house 2, in the present invention, a flow of the air 6 reaching every corner in the house 2 can be created, and the temperature inside the house 2 Since the humidity is averaged, the humidity generated by the flow of the air 6 can be easily removed even if the humidity is increased locally, and the growth of fungi such as mold can be suppressed.

  The entire house 2 can be gradually warmed by the air conditioning equipment 7a installed in one room 7, or the room 7 in which the air conditioning equipment 7a is installed can be sealed to heat only the room 7. However, care must be taken not to induce a local increase in relative humidity.

  By circulating the air 6, the temperature and humidity of all the rooms 7 in the house 2 can be evenly heated and comfortable without having to be cold by simply using air conditioning equipment such as air conditioning equipment 7a. Will be able to control.

  The present invention has an underfloor drying effect in summer, an underfloor heating effect in winter, and an air purifying effect throughout the year, so that temperature and humidity can be adjusted comfortably throughout the year.

  FIG. 4 is a perspective view of a fan used in the circulation type air conditioning system according to the present invention. As the fan 5, a sirocco fan or a turbo fan is used.

  As shown in FIG. 4, the sirocco fan is a centrifugal fan in which a large number of narrow and long wings are attached to the circumferential portion of a cylindrical frame, and blows in the circumferential direction from the center by rotating. be able to.

  The turbofan is a centrifugal fan in which a wide wing is attached to the circumferential portion of a cylindrical frame in a rearward direction, and can rotate in the circumferential direction from the center by rotating. Note that other fans 5 may be used.

  As described above, the circulation type air conditioning system according to the present invention eliminates the temperature difference between rooms by circulating the air of the entire house without installing air conditioning equipment in each room, and efficiently Humidity can be adjusted.

  By using a heat insulating material on the walls, ceiling, and floor of the house, a comfortable temperature can be maintained without being affected by outside air. Moreover, the use of air-conditioning equipment can be suppressed by arranging the heat storage concrete under the floor.

  By circulating the air in the whole house including under the floor without stagnation and averaging the temperature, it is possible to suppress the increase in local relative humidity caused by the temperature difference of the air. The occurrence of fungi such as mold that adversely affect the maintenance of the health of the plant is reduced.
