Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an air conditioning system using a heat storage material.

(Prior Art) Conventionally, there has been known a floor heating device which is incorporated in a floor of a house of a heat storage material. For example, Japanese Patent Laid-Open No. 1-217135 discloses a combination of a heat storage material incorporated in a floor of a house and a heating source, which stores heat in the heat storage material using inexpensive late-night power, solar heat, etc. A method of using it for floor heating has been proposed.

In such a floor heating device, it is easy to use the heating source as a cold heat source, and by doing so, cold heat can be stored in the heat storage material. Therefore, if a heat source that can be used as a cold heat source is installed on the ceiling or the like in the room, the concept of the floor heating device may be applicable to the indoor air conditioning system.

(Problems to be solved by the invention) However, when the above concept of the floor heating system is directly applied to the ceiling-mounted air conditioning system, how to treat the drain water generated on the surface of the heat storage material during the cooling operation in the summer Is a problem. A common drain water treatment method is to collect drain water in a drain passage and discharge it outside the room.However, this method not only requires an extra member such as a drain pipe, but also requires a large amount of installation work. There is a problem that becomes.

The present invention has been made in view of the above problems, and by adopting a new way of thinking about the treatment of drain water that has condensed during cooling, it is a method that uses a heat storage material, but does not require extra members. , The purpose is to provide an air conditioning system that can be easily installed.

(Means for Solving the Problem) Therefore, in the air conditioning system of claim 1, the hygroscopic heat storage material 2 is provided inside the casing 11 having the porous plate 21 on the indoor side.
And a heating medium passage 3 for cooling and heating the hygroscopic heat storage material 2 is introduced into the casing 11 and the cooling operation is performed by cooling the hygroscopic heat storage material 2. A radiation unit 1, a ventilation fan 4 installed in an air-conditioned room, and control means 6 and 41 for operating the ventilation fan 4 when the hygroscopic heat storage material 2 is heated by the heat medium passage 3. It is characterized by having.

Further, in the air conditioning system according to claim 2, the hygroscopic heat storage material 2 is housed in a casing 11 having a porous plate 21 on the indoor side, and the hygroscopic heat storage material 2 is further housed in the casing 11.
A radiation unit 1 formed by introducing a heat medium passage 3 for applying cold heat to the inside, a heating means such as a heater for heating the hygroscopic heat storage material 2, and a ventilation fan 4 installed in an air-conditioned room.
And control means 6 and 41 for operating the ventilation fan 4 when the heating means operates.

(Operation) According to the air conditioning system of claims 1 and 2,
Cold heat is stored in the heat storage material 2 through the heat medium passage 3, whereby the cooling operation is performed. When dew condensation occurs on the surface of the porous plate 21 at that time, the moisture is absorbed by the hygroscopic heat storage material 2. After that, the heat storage material 2 is transferred to the heat medium passage 3
When it is heated by using or is heated by a heating means such as a heater, the moisture absorbed in the heat storage material 2 is released, and the released moisture is discharged to the outside by the ventilation fan.

(Embodiment) Next, a concrete embodiment of the air conditioning system of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example in which the air conditioning system according to the embodiment of the present invention is installed in a toilet, a washroom, a kitchen, a bathroom or the like. This air conditioning system A has a radiation unit 1 and an indoor ventilation fan 4 for ventilating the room, and the radiation unit 1 is mounted on the ceiling surface. The radiation unit 1 has a panel-like shape, and as shown in FIG. 2, has a porous plate 21 such as a porous fluororesin plate inside the casing 11 and has hygroscopicity inside thereof. It stores the heat storage material 2. The heat medium passage 3 is introduced into the casing 11 of the radiation unit 1 so that the heat absorbing material 2 can be heated or cooled. As the hygroscopic heat storage material 2,
90% ethylene glycol, 40% lithium chloride and the like can be used, but are not limited thereto.

The heat medium passage 3 is connected to the heat pump system 5, and the heat medium flows into the heat medium passage 3 by operating the heat pump system 5. 51
Is a compressor, 52 is a four-way switching valve, 53 is a heat exchanger, 54 is an expansion valve, and 55 is an accumulator.

The indoor ventilation fan 4 is diverted from the one mounted on the wall surface opening or the like to ventilate the area around the water, and its control device 41 and the control device of the heat pump system 5 are used.
56 and 56 are controlled by the timer 6.

With the above configuration, when cold heat is stored in the heat storage material 2, the heat pump system 5 is operated to evaporate the refrigerant in the heat medium passage 3. When the room R is cooled in the summer, the cold heat stored in the heat storage material 2 is discharged, or the heat pump system 5 is operated to evaporate the refrigerant in the heat medium passage 3.
At this time, dew condensation may occur on the surface of the porous plate 21, but the drain water generated by the dew condensation is absorbed by the hygroscopic heat storage material 2. Therefore, it is unlikely that the condensed drain water will drip into the room.

On the other hand, when the hygroscopic heat storage material 2 releases the absorbed moisture, the heat medium passage 3 is used as a heating means. That is, the four-way switching valve 52 is switched to operate the heat pump system 5 to flow a high-temperature heat medium into the heat medium passage 3 to heat the heat storage material 2. In this way, the moisture absorbed by the heat storage material 2 is released. Along with this, the humidity in the room R rises, so that the indoor ventilation fan 4 is operated to ventilate the room R and discharge the released moisture to the outside.

That is, since the places around the water such as toilets are frequently used in the daytime and are rarely used at night, the room is cooled in the daytime in the summer, and the moisture is released from the heat storage material 2 and the indoor ventilation fan 4 at night when there is no person. Ventilation of the room is performed to remove the moisture absorbed by the heat storage material 2 in the daytime,
The hygroscopicity of is regenerated. Control of the heat storage of the cold heat, the heating of the hygroscopic heat storage material 2, and the operation of the ventilation fan 4 at that time is based on the timer 6 and each control device 41,
Done by 56. A heater may be attached to the heat storage material 2 as a heating means, and the heater may be operated to heat the heat storage material 2.

On the other hand, when heating is performed in winter, the heat pump system 5 is operated by using inexpensive late-night power or the like to flow a high-temperature heat medium into the heat medium passage 3 and store the heat in the heat storage material 2 and store the heat in the daytime. Economical heating can be achieved by releasing it indoors. When the amount of heat is insufficient after the heat is released from the heat storage material 2 and sufficient heating cannot be performed, a high-temperature heat medium may be passed through the heat medium passage 3 to compensate for the amount of heat released.

(Effect of the Invention) The air conditioning system according to claim 1 and claim 2 is a system in which the drain water absorbed in the hygroscopic heat storage material is released by heating the heat storage material and then discharged outside by a ventilation fan. Since it has been adopted, it does not require extra members such as drain pipes, so the space for installation can be reduced, and at the same time the installation work becomes simple.
