  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an overall system configuration diagram showing a first embodiment of the housing heat storage type air conditioning system of the present invention, and FIG. 2 is a cross-sectional view taken along the line CC of FIG. 1 and a reinforced concrete structure in which a reinforcing bar 30 is embedded. A cover body 31 is provided on the surface of the slab 2 in the closed space S of the body.

Grooves 32 are formed on the surface side of the slab 2, and the grooves 32 communicate with each other to form a heat transfer space in which a plurality of branched flow paths are formed between the surface of the slab 2 and the cover body 31. A comb-like heat transfer space S1 is formed, and a pipe 8 from the heat exchanger 7 is connected to the heat transfer space S1.

  Further, a steel bar 33 as a protrusion is connected to the reinforcing bar 30 by welding at a predetermined interval in the longitudinal direction, and the lower end of the steel bar 33 protrudes into the groove 32.

According to the first real施例, temperature control air is transferred to the steel rod 33 with heat is transferred to the surface of the slab 2 by flowing in the heat transfer space S1. Since the heat conductivity of the steel bar 33 is high, the heat of the temperature-controlled air is efficiently transmitted to the steel bar 33, and heat is transferred to the rebar 30 through the steel bar 33 at an early stage. It can be transmitted to the inside of the slab 2 through the reinforcing bar 30, and heat can be efficiently stored in the entire slab 2. The amount of heat storage can be increased by more than about 10 times compared to the conventional configuration, which is extremely effective for the peak cut of electric power. Further, if the groove 32 can be formed in advance by the formwork or the like when the slab 2 is constructed, there is an advantage that it is possible to construct at low cost without requiring new construction.

  In the first embodiment, when the stored heat is positively used in the daytime or the like, the air in the indoor space R is sucked from the indoor outlet 35 formed in the duct 34 and sent to the heat transfer space S1, and the slab It is only necessary to exchange heat with the heat stored in 2 and then return to the indoor space R, and the case of cooling will be described in detail as an example.

  That is, since the relatively warm air in the room rises and stays in the upper part, the warm air from the indoor space is smoothly introduced into the heat transfer space S1 by creating an air flow as indicated by the dotted arrows in FIG. The Therefore, the cold energy stored in the slab 2 can be recovered to become cold air and sent out indoors through a duct of another system. This cold air circulates down in the room, whereby the warm air in the room is pushed up and introduced into the heat transfer space S1, and by repeating these, the cold stored in the slab 2 is effectively used for cooling. be able to.

  It is also effective to change the air flow direction positively. This is because heat is transferred better as the temperature difference is larger. For example, in FIG. 2, when the cold air is flown as indicated by the solid line arrow, the difference between the temperature of the cold air and the temperature of the slab 2 is large at the upstream side of the flow path at the initial stage of heat storage. Is easy to store heat. On the other hand, on the downstream side of the flow path, the temperature of the cold air is increased by the heat exchange with the slab 2 so far, the temperature difference is decreased, and the heat storage rate is decreased. When the heat storage on the upstream side of the flow path proceeds to some extent, the difference between the temperature of the cold air on the upstream side and the temperature of the slab 2 becomes small, and the movement of heat becomes small. Along with this, the heat transfer at the midstream portion increases, and by repeating these, cold heat is stored in order from the upstream portion to the downstream portion.

Therefore, the air flow direction is switched as indicated by the dotted line in the middle of the above heat storage process, and the cold air is first supplied downstream with respect to the solid arrow. Since the downstream side of this solid arrow is not stored much heat, the difference between the temperature of the cold air and the temperature of the slab 2 there is large, the heat transfer rate can be increased, and the cold heat storage rate can be increased. Overall, the heat storage speed can be increased, the operation time of the heat exchanger 7 and the fan can be shortened, and the running cost can be reduced.
This is not limited to heat storage, and heat recovery speed can be increased in heat recovery, and the same effect is obtained.

That is, a housing 36 as a heat transfer promoting member for expanding the heat transfer area is attached to a portion of the steel bar 33 protruding into the closed space S1, and the heat of the temperature-controlled air is more efficiently supplied to the steel bar 36. It is configured to be communicated. Other configurations are the same as those of the first embodiment. Also in the second embodiment, similarly to the first embodiment, if the groove 32 can be formed in advance at the time of the construction of the slab 2 by a mold or the like, there is an advantage that it can be constructed at low cost without requiring new construction. is there.

The comb-like heat transfer space S2 is formed, and although not shown, a pipe from the heat exchanger is connected to the heat transfer space S2.

  Further, a steel plate 40 as a projection is connected to the steel frame 37 at a predetermined interval in the longitudinal direction by welding, and the lower end of the steel plate 40 protrudes into the groove 39.

  According to the third embodiment, the temperature-controlled air flows in the heat transfer space S <b> 2, whereby heat is transferred to the surface of the slab 2 and is also transferred to the steel plate 40. Since the heat conductivity of the steel plate 40 is high, the heat of the temperature-controlled air is efficiently transferred to the steel plate 40, and heat is transferred to the steel frame 37 at an early stage via the steel plate 40, and the slab is passed through the steel plate 40 and the steel frame 37. 2 to the inside of the slab 2 can be efficiently stored. Further, if the groove 39 can be formed in advance by the formwork or the like at the time of construction of the slab 2, there is an advantage that it can be constructed at low cost without requiring new construction.

Other configurations are the same as those of the third embodiment.

  FIG. 9: is a whole system block diagram which shows 5th Example which concerns on the housing heat storage type air conditioning system of this invention, The places different from 4th Example are as follows.

  In other words, the positions of adjacent steel plates 40 are shifted, and the steel plates 42 are connected to one end in the horizontal direction of each of the steel plates 40, so that one continuous flow path is formed as a zigzag heat transfer space of one continuous flow path. The heat transfer space S4 is formed so that For this reason, the temperature-controlled air introduced into the heat transfer space S4 flows through one flow path, and the flow velocity thereof is greatly increased. Therefore, the heat transfer rate to the slab 2 can be increased, and the heat transfer speed. There is an advantage that can be faster. However, although the pressure loss increases, it can be sufficiently dealt with by using a fan having a large discharge pressure as a fan (not shown). Other configurations are the same as those of the fourth embodiment.

  As a heat transfer promoting member in the second embodiment, a plurality of thin wire numbers 21 are attached to the steel rod 33 as shown in the side view of FIG. Or a thin steel plate 22 as shown in the perspective view of FIG. 10 (b), or a steel spiral member 23 as shown in the perspective view of FIG. 10 (c). Various configurations can be employed.

For example, a closed space may be formed between the slab 2 and the floor board above the slab 2, and temperature-controlled air may be supplied to the closed space to store the housing heat.

  Thus, in the case where the closed space is formed on the upper side of the slab 2, if the first embodiment, the second embodiment, the third embodiment, the fourth embodiment, and the fifth embodiment are applied, the cover body 31, 38 can be placed and supported on the grooves 32 and 39, and the cover body 41 can be placed and supported on the steel plates 40 and 42.
