Subsequently, when the room 3 is used in the daytime, an air conditioner 13 is operated, the air conditioner 11 is stopped, at this time, the air in the ceiling 5 is blown-off into the room 3 by the operation of a fan 17. The hot-air blown-off from the air conditioner 13 is supplied into the room 3, a part of the blown-off air is introduced into the ceiling 5, then heated with the accumulated slab 14, the hot-air is blown- off into the room 3 from a blown-off port 18 with the fan 17, thus the inside of the room 3 is heated.

Description

Detailed Description of the Invention The present invention relates to a room air conditioning method, and in particular, an air conditioner is operated to heat or cool a building frame when the room is not in use. By operating the air conditioner, the air blown out is further heated or cooled by the building frame, and this air is used to heat or cool the room, thereby making the heat load on the air conditioner as uniform as possible. This prevents the air conditioner from becoming larger.

In general, in systems where room air conditioning is performed only while the room is in use, the heat load of the air conditioner fluctuates greatly, as shown by the chain line in Figure 1, and the peak of the heat load appears. The time is short. During most of the other time periods, the heat load is significantly lower than the peak value. However, if the capacity of the air conditioner is determined by the peak value, the time during which the air conditioner is under a load of 100 yen will be short, and most of the time will be spent in inefficient low-load operation. Also,
In order to use an air conditioner that can withstand the heat load of the above-mentioned peak value, the size of the air conditioner has to be increased.In addition, since the operation of the air conditioner is stopped when the room is not in use, the use of the air conditioner becomes difficult. I don't like the efficiency.

Therefore, in order to solve the above-mentioned problems and use surplus electricity at night, we perform a heat storage operation when the room is not in use, storing heat in advance and using the heat for heating and cooling when the room is in use. The method used is as follows. According to this, the operating time of the air conditioner will be longer, but as shown by the solid line in Figure 1, it is possible to make the load on the air conditioner as uniform as possible by reducing the peak value. It becomes possible.

Figures 2 and 3 show this method. That is, in FIG. 2, a room 3 is formed between a ceiling 1 and a slab 2 forming a floor, and an air conditioner 4 outside the room 3 is connected to a duct 6 arranged in the attic 5 and a duct 6 The figure shows how hot or cold air is blown into the room 6 via a blow-off lower connected to the ceiling 1 and attached to the ceiling 1, thereby heating and cooling the inside of the room 6.

The air conditioner 4 is shown with the same reference numerals in FIG.

This air conditioner 4 exchanges heat with cold water or hot water 10 in a water tank 9, which has been heated in advance by a heater 8, to generate cold air or hot air. Heat is stored as cold water or hot water 10 by the refrigerator or heater 8 used. When the room 6 is in use, the air conditioner 4 blows cold or warm air using cold water or hot water 10 as a heat source into the room 3 for heating and cooling, as shown in FIG.

However, such conventional air conditioning methods require a large water tank 9 with a large heat storage reservoir, and the water tank 9 is generally installed in a location away from the room 6, such as in a mechanical room of a building or in an underground beam. Therefore, there is a problem that large heat loss occurs in the pipe connecting the water tank 9 and the air conditioner 4, and there is also a problem that heat loss of the cold water or hot water 10 in the water tank 9 occurs. Furthermore, if the water tank 9 becomes large in size, the piping for transferring the cold water or hot water 10 must be of an open piping system, which causes the problem that the power of the pump must be increased.

Therefore, this invention was made to solve such conventional problems, and its purpose is to reduce the peak value of the heat load applied to the air conditioner, and to reduce the heat load applied to the air conditioner. The purpose is to minimize changes in load, but the purpose is to minimize the space occupied by the heating or cooling medium, such as cold water or hot water, to make effective use of building space. Above all, the aim is to reduce heat losses as much as possible.

That is, the present invention provides a method for air-conditioning a room 6 in which periods of use and non-use are repeated at regular intervals, such as daytime and nighttime in a general office, as shown in the illustrated embodiment. , the air conditioner 11 is operated to heat or cool the building frame 12 when the room is not in use, and then,
When the room B is used, the air conditioner 13 is operated, and the air blown out from the air conditioner 13 is further heated or cooled to the heated or cooled building frame 12. , relates to an air conditioning method characterized by heating or cooling the inside of the room 6.

Next, the present invention will be explained based on illustrated embodiments. FIG. 4(A), 03) shows a first embodiment of the present invention, in which 6 is a room that is a space to be heated, 4-2 is a slab that is the floor of the room, and 1 is the ceiling of the room. , 14 are slabs that are the floors of the upper floors, and both slabs 2 and 14 form the frame 12 of the building. Further, 5 is an attic area formed between the slab 14 and the ceiling 1.

The room 6 has double window glass 15 and a partition wall 1 in the horizontal direction.
An air conditioner 11 is installed on the outside of the partition wall 16 and is operated when the room 6 is not in use, for example at night, and the air outlet 11a of the air conditioner 11 opens facing the attic 5. ing.

The ceiling 1 has an air outlet 18 equipped with a fan 170 and a ceiling louver 19, and an air conditioner 16 that is operated when the room 3 is used is installed on the slab 2 inside the window glass 15. 20 is a heat insulating material.

Therefore, when room 3 is not in use, such as at night, the
), the air conditioner 11 is operated and warm air is blown into the attic 5 from its outlet 11a.

Since there is no duct in the attic 5, the warm air flows through the attic 5.
It is directly distributed throughout and is also supplied into the room 3 via the ceiling louver 19. At this time, the fan 17 is in a stopped state. Therefore, the attic 5 and the room 6 are heated by this hot air 6, and the heat is stored in the concrete slabs 14 and 2, which have a particularly large heat capacity.

Next, when room 3 is used during the daytime, as shown in Fig. 4 (B).
As shown in the figure, the air conditioner 16 is operated and the air conditioner 11 is stopped. At this time, fan 17 is also operated,
The air in the attic 5 is blown out into the room 3.

The hot air coming out of the air conditioner 13 is supplied into the room 6, and a part of it is sucked into the fan 17 and enters the attic 5 through the ceiling louver 19, where it is transferred to the heat-storing slab 14. The heated air is then sent to the fan 17 through the air outlet 1.
8 into the room 3 to heat the room 3. Further, the hot air that does not enter the attic 5 and the hot air blown out from the air outlet 18 are heated by the heat-storing slab 2 in the room 3, thereby heating the room 6.

Note that if there is furniture, office equipment, or utensils that have a large heat capacity in the room 3, heat will be stored there, and heating can be performed using this stored heat.

Although the above embodiment described heating the interior of the room 6, the same applies to cooling. The cold air is blown from the air conditioner 11 to cool the slabs 2 and 14, and then the cold air blown from the air conditioner 13 is By further cooling the air with the slabs 2 and 14, the interior of the room 3 can be cooled.

A second embodiment of the present invention is shown in FIGS. 5(5) and 5(B). That is, this embodiment differs from the first embodiment mainly in the following two points. The first is that the latent heat storage material 21 is provided on the upper surface of the ceiling 1 facing the attic 5, and the second is that the suction port 11b of the air conditioner 11 is placed facing the attic 5. As the latent heat storage material 21, chemical substances having the characteristics shown in Table 1, for example, are suitable.

(Table 1) Therefore, in this embodiment, in addition to the slabs 2 and 14 as the building frame 127-, heat is stored in the latent heat storage material 21, and the air outlet 11a of the air conditioner 11 and Since the suction ports 11b both face the attic 5, heat is mainly stored in the slab 14 and the heat storage material 21, and when the room 6 is used, the heat is radiated and the room is opened in the same manner as in the first embodiment. It is used for air conditioning and heating in No. 6. Others are the first
It is almost the same as the example.

FIG. 6 shows a third embodiment of the present invention, in which an air conditioner 11 is installed outside the room 3 for power generation at night, which operates when the room 3 is not in use, and an air conditioner 11 for power generation during the daytime, which operates when the room 3 is in use. Harmonizer 22
This is an example in which an air conditioner is not installed in room 3. The air conditioner 11 for night power use has the air outlet 11a and the inlet 11b facing the attic space 5 as in the second embodiment, and the air conditioner 22 for daytime power use has the air outlet 11a and the air inlet 11b facing the ceiling 5.
is placed in the attic, and the suction port 22b faces the room 6, respectively.

Therefore, when the room 6 is not in use, the air conditioner 11 blows hot air into the attic 5, and heat is mainly stored in the slab 14 and the latent heat storage material 21, and when the room 3 is in use, the air is Operate the harmonizer 22 and open the air outlet 22a.
The warm air blown out from the frame 12 is further heated by the stub 14 and the latent heat storage material 21, and is blown into the room 6 through the air outlet 18 by the fan 17 to heat the room 3. The air in the room 6 is again introduced into the attic 5 from the ceiling louver 19 and is reheated. In FIG. 6, arrows indicated by broken lines indicate airflow when the air conditioner 11 is operating, and arrows indicated by solid lines indicate airflow when the air conditioner 22 is operating. Note that the same applies to cooling.

FIG. 7 shows a fourth embodiment of the present invention, in which an air conditioner 26 that operates when the room 3 is used is connected to a fan coil unit (23a) installed in the room 6 and connected to this via a conduit 23b. The ceiling louver 19 can be opened and closed freely, and the ceiling louver 19 is closed when the air conditioner 11 is in operation. Therefore, sufficient heat is stored in the slab 14 and the latent heat storage material 21, and almost no heat is stored in the slab 2.

Further, when the air conditioner 23 is in operation, the ceiling louver 19 is opened.

The airflow in this case is similar to that shown in FIG. 5(B). Note that the arrow shown by a broken line is the airflow when the air conditioner 11 is in operation, and the arrow shown by a solid line is the airflow when the air conditioner 26 is in operation. This is similarly used for cooling.

As explained above, according to the present invention, there is no need for special heat storage equipment such as a water tank, which uses the building frame forming the building itself as a heating or cooling medium. While space can be used effectively, energy loss can be minimized because the heating or cooling medium, that is, the building frame, and the room to be heated or cooled are located closest to each other. . However, air conditioners have the effect of lowering the peak value of the heat load by running it when the room is in use and when it is not in use, thereby minimizing changes in the heat load.
