Abstract

PURPOSE:To absorb efficiently the air heat in the space in the ceiling and be able to cool the space by installing continuously primary and secondary receivers for dew condensation water which are formed with specified material and installed under a heat exchanging pipe which is installed in the ceiling and to which cooling water is supplied. CONSTITUTION:Primary receivers 6 for dew condensation water formed with high-conductive material are installed under a meandering heat exchanging pipe 5. Under the primary receivers 6 secondary receivers 7 for dew condensa tion water formed with low-conductive material are installed. When cooling water is circulated in the pipe 5, the air heat in the space 4 in the ceiling is absorbed by the pipe 5 and the air is cooled. The dew condensation water generated on the periphery of the pipe 5 falls down on the receivers 6 and even by the receivers 6 the air heat in the space 4 is absorbed and the dew condensation water is discharged through recessed groove parts 6a. The dew condensation water generated on the receivers 6 is recovered by the receivers 7 and then discharged and the dew condensation water is not generated on the receivers 7. Thereby, the interior of a room is kept at the optimum temp.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a novel cooling system that can be easily implemented and applied to various buildings in which a space is defined in the ceiling.

"Conventional technology and its problems" In the past, air conditioners were usually installed at appropriate locations in the room.
The desired cooling condition is achieved by absorbing the heat of the sucked air with a refrigerant and forcing the cooled air back into the room.

However, in such conventional cooling systems, even if a separate air conditioner with a separate condenser etc. is used, at least the blower must be installed indoors, so even if blowers have become relatively thin in recent years. As usual, the installation location is naturally limited due to the size of the blower, etc.
A major problem was that the installation unnecessarily narrowed down the indoor space.

In addition, conventional forced air ventilation causes noise and
Air conditioning disease has become a social problem, especially in recent years, because it is much cooler than the ceiling.

Furthermore, regardless of the type of conventional air conditioner, not only does it consume a lot of electricity, but it also requires electrical work, so it is currently viewed as a major economic problem. It is.

"Means for Solving the Problems" Therefore, the present invention was developed to effectively solve the problems of the prior art. A heat exchange pipe to which water is supplied is arranged in a bellows-like shape, and a primary condensation water receiver made of a material with high thermal conductivity is continuously provided below the bellows-like heat exchange pipe. A configuration was adopted in which a primary condensation water receiver molded from a material with low thermal conductivity was continuously provided below the primary condensation water receiver, and the ceiling of the building was made into a ventilation structure.

"Operation" Accordingly, in the present invention, when cooling water is supplied and circulated within the heat exchange pipe, the heat of the air existing in the attic space is
At the same time as the heat is absorbed and cooled by the heat exchange pipe, condensation water is actively generated on the surface of the heat exchange pipe by absorbing the heat of the air, and the condensation water is transferred to a pipe made of a material with a high heat exchange rate. Since the primary condensation water receiver is dropped upward and the primary condensation water receiver is also cooled, the heat of the air in the space is extremely efficiently absorbed by the condensation water and the primary condensation water receiver. This means that it can be cooled.

In addition, the condensed water generated in the primary condensation water receiver is collected in the primary condensation water receiver provided below the primary condensation water receiver and drained to the outside. The reception is
Since it is molded from a material with low thermal conductivity, it does not generate condensation water like the primary condensation water receiver, so there is no worry that the ceiling will corrode due to condensation water.

Therefore, the air that is efficiently cooled by the heat exchange pipe, condensation water, and primary condensation water receiver naturally falls into the room through the ceiling ventilation structure, is heated, and rises again to be cooled by natural convection. By repeating cold radiation, the interior of the room is always maintained at the optimum temperature and condition.

``Example'' The present invention will be described in detail based on an example illustrating the present invention.The cooling device according to the example was developed based on an unprecedented new idea, and its characteristics are as follows. The problem lies in the following configuration.

That is, the basic structure of the air conditioner of this embodiment is as shown in FIG. A heat exchange pipe 5 to which cooling water is supplied is arranged in the attic space 4 in a bellows shape, and below the bellows-shaped heat exchange pipe 5,
Primary condensation water receivers 6 made of a material with high thermal conductivity (e.g. copper plate, aluminum plate, etc.) are provided continuously in the same bellows shape at regular intervals. 6, primary condensation water receivers 7 made of a material with extremely low thermal conductivity (for example, urethane, etc.) are provided continuously in a bellows shape at regular intervals.

Therefore, as shown in FIG. 2, the heat exchange pipe 5, the primary condensation water receiver 6, and the primary condensation water receiver 7 are installed in the above-mentioned attic space 4 through support members (not shown). Thus, they are arranged continuously in the vertical direction on the same bellows line.

Further, as shown in the figure, the heat exchange pipe 5 is a metal pipe made of copper, aluminum, etc. with spiral fins 5a provided on the outer periphery, and although not specifically shown in the figure, it is connected to a cooling water generator. The generator is configured so that cooling water at a predetermined temperature is continuously supplied and circulated from the generator.

Further, as shown in the figure, the primary and primary condensation water receivers 6 and 7 have a substantially V-shaped or U-shaped cross section, and use their respective central concave grooves 6a and 7a to prevent water from falling. The structure shall be such that dew condensation water can be efficiently drained to the outside.

Furthermore, in this embodiment, there are ventilation holes 1 in the ceiling material 1.
For example, by using a louver ceiling material or the like, the entire ceiling is made into a ventilation structure, and the cold air in the attic space 4 is allowed to fall naturally into the room through the ventilation structure, or conversely, the warm air in the room is The structure is such that it can naturally rise into the attic space 4 through the ventilation structure. Further, reference numeral 8 in the figure is a heat insulating material laid between the ceiling joists 3, and 9 is a thermostat that controls the movement of the entire apparatus according to the room temperature.

Therefore, when a device with such a configuration is used to cool a room, cooling water is supplied and circulated from the cooling water generator into the heat exchange pipe 5 disposed in the attic space 4. The heat of the air existing in the attic space 4 is efficiently absorbed and cooled by the outer periphery of the heat exchange pipe 5 and the spiral fins 5a.

Then, in this embodiment, condensed water is actively generated on the outer circumferential surface of the heat exchange pipe 5 and the surface of the spiral fins 58 due to the absorption of heat from the air. This condensation water and the cooled primary condensation water receiver 6 fall onto the primary condensation water receiver 6 made of a material with a high exchange rate and cool the primary condensation water receiver 6. In this way, not only the heat of the air in the attic space 4 is absorbed even more efficiently, but also the condensed water is immediately drained to the outside through the groove 6a of the primary condensed water receiver 6.

Note that the fact that the primary condensation water receiver 6 is cooled and absorbs the heat of the air means that the primary condensation water receiver 6 also has a heat exchange pipe 5.
Although condensation water is generated even if it is not so much, in this embodiment, the primary condensation water receiver 7 is provided below the primary condensation water receiver 6 at a certain interval. The condensed water generated in the primary condensation water receiver 6 is collected in the primary condensation water receiver 7 and efficiently drained to the outside.

However, this primary condensation water receiver 7 is different from the primary condensation water receiver 6.
Unlike, since it is molded from urethane etc. with extremely low thermal conductivity, no condensation water will form in the primary condensation water receiver 7, so there is no need to worry about the ceiling material 1 being corroded or damaged by condensation water. Not at all.

Therefore, the air that is efficiently cooled by the heat exchange pipe 5, each of the condensed water mentioned above, and the primary condensed water receiver 6 naturally falls into the room through the ventilation hole 1a of the louver ceiling material 1, and flows through the room from the top. By repeating the cooling radiation caused by natural convection, which is heated in the process of descending and cooled again by rising into the attic space 4, the indoor temperature is maintained at the optimum temperature.

Moreover, the natural convection cooling radiation caused by the temperature difference in this embodiment not only eliminates the worry of noise caused by forced air as in the past, but it is relatively warm compared to the ceiling side, which has not been a problem in the past. There is no need to worry about air conditioning sickness.

In addition, in this embodiment, the fact that condensed water is actively generated means that not only can the condensed water be used as a cooling medium, but also the moisture in the air can be efficiently dehumidified, so it can be used in hot and humid countries like Japan. It is by far the most suitable for summer cooling.

In the above embodiment, one primary condensation water receiver 6 made of a material with high thermal conductivity is provided between the heat exchange pipe 5 and the primary condensation water receiver 7. However, as shown in FIG. 3A, it is optional to provide two or more primary condensation water receivers 6, depending on the implementation. With this configuration, cooling and dehumidification of the air will be further promoted.

Also, especially regarding the shape of the primary condensation water receiver 6.

The embodiment is not limited to the above embodiment, and for example, FIG.
As shown in the figure, it is also possible to form the cross-sectional shape into an inverted V-shape and use grooves 6a and 6a formed on both sides to efficiently drain the fallen condensed water to the outside. It is optional.

Further, although not specifically shown, by connecting the heat exchange pipe 5 to a cold/hot water generator, it goes without saying that this device can be used as a cooling device in the summer and as a heating device in the winter. However, when used as a heating device,
It is necessary to provide a fan means or the like for forcibly blowing the warmed air in the attic space 4 into the room.

"Effects of the Invention" As described above, the present invention provides a heat exchange pipe that is arranged in a bellows shape to which cooling water is supplied in a space defined in the attic of a building, A primary condensation water receiver made of a material with high thermal conductivity is continuously provided below the pipe, and a second condensation water receiver made of a material with low thermal conductivity is provided below the primary condensation water receiver. It is characterized by having a continuous primary condensation water receiver and a ventilation structure in the ceiling of the building, so unlike conventional air conditioners, the installation location is restricted, and the installation requires indoor use. The space is no longer unnecessarily constricted.

Furthermore, by employing the above configuration, the air conditioner of the present invention performs cooling radiation by natural convection, but it not only completely prevents the generation of noise, which is considered a problem with conventional forced air blowing, but also In addition to eliminating electricity consumption, the cooling radiation of natural convection is relatively warm compared to the ceiling side, making it possible to greatly contribute to countermeasures against air conditioning disease, which has become a problem in recent years.

Furthermore, in the present invention, even if condensation water is actively generated, the primary condensation water receiver provided at the lowest level is molded from a material with low thermal conductivity, so that condensation water can be generated easily. Since there is no need to worry about corrosion or damage to the ceiling, it is possible to provide an extremely economical cooling system with excellent cooling capacity.
