Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an air conditioning system using cold water and hot water in collective housing such as condominiums and office buildings.

[Prior art and its disadvantages] In the case of a conventional air conditioning system that uses cold water and hot water, a main outgoing pipe and a returning pipe are installed, and cold water or hot water is supplied to each dwelling unit from the main outgoing pipe.
A method is adopted in which cold or hot water is returned to the main return pipe after it is used in each residence, and all pipes are covered with insulation material.

As a result, common areas such as elevator halls and hallways are not heated or cooled at all, so these areas may become hot or cold.

[Purpose of the present invention] The present invention is proposed in view of the above points.
The purpose is to use the residual heat of the heat medium that has finished being used in each dwelling unit to cool and heat common areas.

[Structure and operation of the present invention] In order to achieve the above object, the present invention employs the following structure in an air conditioning system for an apartment complex.

The common area outgoing pipes from the main cold water outgoing pipe and hot water outgoing pipe to each residence are pipes covered with insulation material, and the two systems of return pipes leading from each residential unit to the main cold water return pipe and hot water return pipe are common parts of the building. An air conditioning system in an apartment complex where one system is covered with insulation material, the other system is not covered with insulation material, and a drain tray is constructed at the bottom of the heat radiation piping that is not covered with this insulation material. .

In the above-mentioned air conditioning system, the heating medium that has finished dissipating heat in each dwelling unit passes through the heat dissipation piping that does not cover the heat insulating material that is piped to the common areas, and then radiates the heat again while returning to the pipe, thereby cooling and heating the common areas. be.

[Embodiment and its operation] Figures 1 and 2 show an embodiment of the present invention, in which 1 is a common area, 2 is a residential unit, 3 is a main cold water outgoing pipe, 4 is a main hot water outgoing pipe, and 5 is a main cold water return pipe. 6 is the main hot water return pipe, 7 is the common cold water return pipe that connects the main cold water return pipe 3 and the main cold water return pipe 5, and 8 is the common use cold water return pipe that connects the main hot water return pipe 4 and the main hot water return pipe 6. As an outgoing pipe, cold and hot water is supplied to each dwelling unit 2 via a branch residential pipe 9 branched from the cold and hot water outgoing pipes 7 and 8.

10 and 11 are the two systems of return pipes connected to the branch return pipes 12 from each dwelling unit 2 and connected to the main cold water return pipe 5 and the main hot water return pipe 6, and the 11 side of the code is the common part 1. 13 is a drain tray disposed along the bottom of the common area heat radiation pipe 11, which is piped without covering with a heat insulating material.

Next, to explain the operation of the above embodiment, in the case of air conditioning, cold water is supplied from the main cold water outgoing pipe 3 to each dwelling unit 2 via the common area cold water outgoing pipe 7 and the branch outgoing pipe 9 to perform air conditioning. . Cold water that has risen in temperature due to air conditioning, but still has sufficient cold energy, releases its cold residual heat to the common area 1 as shown by arrow a in Figure 2 while passing through the common area heat radiation piping 11. It cools the part and reaches the main cold water return pipe 5. When cooling the common area 1, the drain condensed on the common area heat radiation piping 11 is collected in a drain tray 13 and removed. The hot water supply during this period is as follows: main hot water outgoing pipe 4 → common area hot water outgoing pipe 8 → branch outgoing pipe 9 → branch return pipe 12 → return pipe 10 → main hot water return pipe 6.

On the other hand, in the case of hot water heating, hot water is supplied to each dwelling unit 2 from the main hot water outgoing pipe 4 via the hot water outgoing pipe 8 and the branch outgoing pipe 9 to perform heating. The hot water whose temperature has dropped due to heating, but which still has sufficient heat, releases its residual heat to the common area 1 as shown by arrow b in FIG. 2 while passing through the common area heat radiation piping 11.
This part is heated and connected to the main hot water return pipe 6. During this period, the cold water supply is as follows: Main cold water outgoing pipe 3 → Common area chilled water outgoing pipe 7 → Branch outgoing pipe 9 → Branch return pipe 12 → Return pipe 10 →
This becomes the main cold water return pipe 5.

[Effects of the present invention] As described above, the present invention installs heat dissipation piping through which cold and hot water returns to the common areas of apartment complexes or office buildings, and uses the residual heat of the returning heat medium to cool and heat the common areas. By doing this, you can expect the following effects.

a.In apartment complexes, etc., common areas are heated and air-conditioned, making the common areas very comfortable to live in.

b. Since the return of hot and cold water, that is, the residual heat, is used, there is no effect on the original heating and cooling, the cost is low, and the equipment is simple.

c. By introducing outside air into each dwelling unit from the common areas that are already heated and cooled, the temperature difference in temperature rise or fall becomes smaller, making it possible to further enhance the energy saving effect.
