Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a cooling panel suitable for use in building frame heat transfer radiation cooling.

[Conventional technology]

Conventionally, in contrast to normal air heating medium cooling, there is building body heating medium radiant cooling. That is, as shown in Fig. 4, in building frame heat transfer radiation cooling, a cooling pipe 2 is embedded in the concrete 1 of the building structure (ceiling, floor, walls, etc.), and a heat transfer liquid is supplied to the cooling pipe 2 from a heat source 3. (refrigerant gas,
(cold water, antifreeze, etc.) through the concrete of the frame 1
is used as a thermal refrigerant to cool the room using the cooling radiation effect. The humidity in the room is then reduced using a separate dehumidifier. This building frame heat storage uses concrete, so for example, the density is 2.250Kg/m ³ and the specific heat is 0.2kcal/
Kg/℃, and the heat storage capacity of the structure is slightly less than half that of water. Body heat transfer radiation cooling is ideal for buildings that require continuous use, for people who are weak in cooling, or for rooms that do not like air blowing out, such as hospital rooms, rooms for the elderly, etc.It is also suitable for schools, art galleries, museums, libraries, etc. where people think for long periods of time. It is also ideal for places where the building itself requires cool comfort, such as design rooms.

[Problem to be solved by the invention]

However, in conventional building frame heat transfer radiation cooling, if the temperature of the structure is low, dew condenses on the surface of the structure, so it is necessary to install a separate dehumidifier indoors to reduce humidity, which increases equipment costs. There is this inconvenience.

In view of the above, an object of the present invention is to propose a cooling panel that can be used for heat medium radiation cooling of a building frame without requiring a separate dehumidifier, thereby significantly reducing equipment costs.

[Means to solve the problem]

The cooling panel 10 of the present invention has a cooling pipe 11 with fins 12, as shown in FIGS. 1 and 2, for example.
This cooling pipe 11 and a part 12a of the fin 12 attached to this cooling pipe 11 are buried in the radiant heat absorbing lightweight material 13, and this fin 12 is
The remaining portion 12b of this radiant heat absorbing lightweight material 1
3, and forms a lid body 14 that covers the periphery of the radiant heat absorbing lightweight material 13 and the entire exposed side of the fins 12 of the radiant heat absorbing lightweight material 13, and the radiant heat absorbing lightweight material inside the lid body 14. The air blower 16 blows air from one side 15a of the fin 12b exposed from the fin 13, and the air is emitted from the other side 15b of the fin 12b.

[Effect]

According to the present invention, when a heat medium liquid is passed through the cooling pipe 11 and air is sent by the blower 16, dew condensation occurs on the exposed fins 12b, and the room is dehumidified by the heat medium liquid for cooling. This eliminates the need for a separate dehumidifier, and reduces the temperature of the radiant heat absorbing lightweight material 13 to lower the indoor temperature, and the radiant heat absorbing lightweight material 13 absorbs the radiant heat generated by humans.
Demonstrates radiation cooling effect. In addition, the air circulation by the blower 16 creates a moderate airflow, and this airflow quickly carries away the layer of air that has become saturated due to the evaporation of sweat toward the body, and also has the effect of dissipating heat from the human body through convection. This will speed up the dissipation of heat through radiation and increase the pleasure of the body.

〔Example〕

Hereinafter, one embodiment of the cooling panel of the present invention will be described with reference to FIGS. 1 to 3.

FIGS. 1 and 2 show an embodiment of the cooling panel of the present invention, and this cooling panel 10 is generally used as a cooling panel 2 that absorbs radiant heat using a building frame shown in FIG. 3, which will be described later.
Used in combination with 0.

In FIGS. 1 and 2, 11 is a cooling pipe, and this cooling pipe 11 is made of copper, aluminum, vinyl chloride, etc. It is formed. 12 is integrated with the cooling pipe 11 on the outer periphery of the cooling pipe 11, and is connected to the cooling pipe 1.
A large number of fins are arranged in parallel to cross the meandering direction of the fin 1, and a part 12 of the fin 12
The fin a is buried together with the cooling pipe 11 in a radiant heat absorbing lightweight mortar (for example, made of cement and lightweight aggregate containing silica as a radiant heat absorbing material) 13 as a radiant heat absorbing lightweight material, and the remaining portion 12b of this fin 12 is Radiant heat absorption lightweight mortar 13
More exposed. Note that a far-infrared absorbing paint is applied to the outer periphery of the cooling pipe 11 so that the heat absorbed by the radiant heat absorbing lightweight mortar 13 is not reflected on the surface of the cooling pipe 11. Both ends of this cooling pipe 11 serve as an inlet and an outlet for a heat medium (refrigerant gas, cold water, antifreeze, etc.) passing through the inside of the cooling pipe 11 protruding from the radiant heat absorbing lightweight mortar 13.

14, the cooling pipe 11 is a part 12 of the fin 12;
It is a lid body that covers the entire exposed side of the fins 12 of the radiant heat absorbing lightweight mortar 13 buried together with the radiant heat absorbing lightweight mortar 13, and includes the fireproof plate members 14a on the four sides of the periphery and the fireproof heat insulating board at the bottom. It consists of member 14b.

Reference numeral 16 denotes an air blower located on one side of the lid 14, which blows air from one side 15a of the exposed part 12b of the fin 12.
Air is made to come out from the other side 15b. 17 is a hook for attachment.

In FIG. 3, reference numeral 21 denotes a cooling pipe, which is formed by bending a single pipe material in a meandering manner. This cooling pipe 21 is made of radiant heat absorbing lightweight mortar 22
The pipe is buried in the pipe, and its both ends protrude from the radiant heat absorbing lightweight mortar 22 to serve as an inlet and an outlet for the heat transfer liquid passing through the pipe. Note that an infrared absorbing material is applied to the outer periphery of the cooling pipe 21 so that the heat absorbed by the radiant heat absorbing lightweight mortar 22 is not reflected on the surface of the cooling pipe 21.

Now, the building frame radiant heat absorption cooling panel 2 shown in Fig. 3
0 is attached to the ceiling or wall, and a heat medium liquid is passed through the cooling pipe 21. For example, if the temperature of the heat medium liquid is 18°C, the surface of the radiant heat absorbing lightweight mortar 22 becomes 23°C, with a difference of 5°C. According to the psychrometric diagram, if the room temperature is 28℃, the relative humidity is 83% and the radiant heat absorbing lightweight mortar 2
Condensation forms on the surface of 2. If cooling is performed only with this body radiant heat absorbing cooling panel 20, dew will condense on the surface of the radiant heat absorbing lightweight mortar 22, and the air will become still and a layer of air saturated with sweat evaporation will be formed on the surface of the body, causing sweat to evaporate. becomes difficult to evaporate and becomes uncomfortable.

Therefore, the cooling panel 1 shown in FIGS. 1 and 2
0 is attached to the building frame radiant heat absorption cooling panel 20.
That is, the cooling pipe 1 is connected to the cooling pipe 11 and the cooling pipe 21 through a joint (not shown).

Air is sent from the other side 15b, and air is circulated by blowing air from the other side 15b. 18℃ when room temperature is 28℃ and humidity is 80%
The fins 12 condense and dehumidify the room using a heating medium for cooling. However, radiant heat absorption lightweight mortar 13
The surface temperature does not drop immediately because of the heat capacity of the radiant heat absorbing lightweight mortar 13. When the relative humidity in the room begins to decrease, the temperature on the surface of the radiant heat absorbing lightweight mortar 13 also begins to decrease due to conduction heat from the buried cooling pipe 11, lowering the indoor air temperature and absorbing radiant heat generated by humans. The mortar 13 absorbs it and exhibits a radiation cooling effect. In addition, the air circulation by the blower 16 creates a moderate airflow, and this airflow quickly carries away the layer of air that has become saturated with sweat evaporation on the surface of the body, and also has the effect of dissipating heat from the human body through convection. It acts to increase the body's pleasure by increasing the heat dissipation speed and increasing the body's pleasure. Note that moisture condensed on the fins 12 is drained away by a drain hose (not shown). Alternatively, one cooling panel 10 may be attached to the surface of the ceiling or wall, but it may be installed using the building frame radiant heat absorption cooling panel 20 as a base, and an appropriate number of cooling panels 10 may be attached to the building body radiant heat absorption cooling panel 20.
It may be attached to the

In this way, in this embodiment, the blower 1 is connected to the fin 12 of the cooling pipe 11 via the heat medium liquid for cooling.
Air is sent from 6 to cool the room while dehumidifying it.
Even in the case of building frame heat medium radiation cooling, the radiation cooling effect can be sufficiently exhibited, and a separate dehumidifier can be eliminated, making it possible to significantly reduce equipment costs.

It should be noted that the present invention is not limited to the above-described embodiments, and it goes without saying that various configurations can be made without departing from the gist of the present invention.
