Abstract

A roof water piping is provided to reduce energy consumption by installing water pipes at a roof of a building. A roof water piping comprises a water inlet(1) and a hot water outlet(2). Water is supplied to the water inlet such that the water is discharged into the hot water outlet by passing through roof pipes. Water supplied to the water inlet has a room temperature. While the water circulates from the water inlet to the hot water outlet, the water is heated by absorbing solar heat collected in a roof. Heat exchanges between the water having a room temperate and the roof, so that hot water is produced and simultaneously the roof is cooled.

It is a new concept top floor ceiling pipe using general heating piping method installed on the floor.

When constructing the building, pipes should be piped on the top floor like hot water pipes. Initial construction costs are increased, but considering the cost of energy saving in the future (which can be used for the life of the building), there is sufficient practical value because it saves resources and saves costs.

When a hot water storage tank is installed separately and the constant in the “ceiling water pipe” is heated to the set temperature, the system to be moved to the hot water storage tank should be the basis.

If the constant flowing in the ceiling water supply pipe is over a certain temperature, the cooling effect will not be seen properly. Therefore, it can be used according to the characteristics of the building by adjusting the rotation rate of the constant.

"Ceiling constant pipe" construction can be installed and used in the same way as floor heating pipes without any special skills.

It is about water supply pipe which can cool and use hot water at the same time by using solar energy (natural energy) in summer.

Since pollution does not occur, it is "green" and maintenance costs are much lower than the cooling and hot water supply methods used in general buildings.

The ceiling surface of the top floor, which is directly exposed to direct sunlight in summer, has a high surface temperature, so the room temperature of the top floor is much higher than that of the other floors.

We have often seen water spraying up on a heated roof to lower the room temperature, which is also a waste of energy and does not show a significant thermal barrier.

In addition, due to the increased room temperature, the top floor residents are suffering from various wastes such as waste of energy and cooling bottles by using too much air conditioner.

In addition, even in summer, the amount of hot water consumed is not small.

People around me take a shower with hot water in the middle of summer, and hot water is always needed in families with babies.

Compared to the amount used in winter, the amount used in summer is not low.

I can see that.

In order to reduce heating and cooling costs for the hot water supply, which is consumed in the hot summer, the idea of the "ceiling constant piping" was conceived.

It is a double effect that can use cooling effect on the top floor and hot water on all floors of the building.

All the buildings, houses, townhouses, apartments, malls, high-rises, etc.

If applied, energy savings would be a big national benefit.

The effect obtained by applying this construction method is to reduce the cost of using hot water in summer and to help the cooling effect of the top floor.

Detailed configuration and application will be explained through drawings.

Figure 1. "Ceiling constant piping" plan

The "ceiling water pipe" is supplied to the hot water outlet (1-2) through the ceiling pipe (pipe pipe) by supplying a general constant from the constant inlet (1-1).

In the constant water inlet (1-1), it is supplied at the temperature of ordinary water supply, but the water in the "ceiling water pipe" absorbs the solar heat collected in the ceiling (and roof) during the movement to the hot water outlet (2). The constant coming out 2) is heated up with hot water.

Then, the heat collected from the ceiling is discharged to the "ceiling water pipe" so that the surface temperature of the ceiling

The high temperature and the low temperature, which is a constant in the "ceiling water pipe," heat exchange to achieve thermal equilibrium.

This thermal equilibrium constant can be used as hot water and the surface of the ceiling

The cooling effect of the interior space of the top floor can be obtained.

The piping plan view of FIG. 1 is an assumption for clarity, and in order to actually apply to a building, it may be designed by applying a facility calculation calculation in consideration of a building use and a user request.

Figure 2. Constant Flowchart

General water is supplied through general water supply (2-1).

Install a pipe connected to the "ceiling water pipe" in the general water supply (2-1) pipe at the beginning of the building to supply general water, and install a shut-off valve (2-9) to use the "ceiling water pipe". Easy opening and closing

The general constant moved to the "ceiling water pipe" (2-3) absorbs the sunlight (2-4) accumulated in the roof and is discharged as hot water to the hot water discharge pipe (2-6).

The hot water thus produced is easily stored in the hot water tank (2-7) to supply all the hot water in the building.

The hot water stored in the hot water tank (2-7) is connected to the hot water supply pipe so that it can be used on all floors in the building.

When the ceiling constant pipe (2-3) is not in use, close the on / off valve (9) and remove the water in the ceiling water supply pipe (2-3) through the drain valve (2-8) to maintain the pipe inside empty. .

Figure 3. Flow chart of hot water obtained through the "ceiling water pipe"

In the same process as above, the hot water obtained from the "ceiling water pipe" is transferred to a tank and used as general hot water.

There are two kinds of water flowing into the hot water tank: the normal water (3-3) and the hot water (3-1) obtained through the "ceiling water pipe".

The “open / close valve (automatic and manual valve)” is installed in the general water (3-3) pipe and the hot water (3-1) pipe installed at the inlet side of the hot water tank (3-2) to meet the user's conditions and environment. Selected as a constant (3-3) or hot water (3-1) is installed to facilitate the supply to the hot water tank (3-2).

(E.g. in summer, use the constant water (3-3) and repair the hot water (3-1).

In winter, hot water (3-1) is used singly and general constant (3-3) is used after repair.)

It is difficult to use in winter because it is a facility that absorbs solar heat from ceiling and uses solar energy. An additional description of this is attached at the end of the "Organization of the Invention".

The hot water (3-1) moved to the hot water tank (3-2) is forced heating through the heating device (boiler) or the temperature of the hot water (3-1), depending on the purpose of use or use of the building You can decide accordingly.

The use of hot water (3-1) heated using natural energy, rather than being forced through a heating device by receiving a general constant (3-3) can obtain energy savings.

The hot water through this path is moved to each place of use through the hot water supply pipe (3-4), and can be used in the same manner as using ordinary hot water. Figure 4. Cooling effect principle of the top floor through the ceiling water supply pipe The ceiling part of the top floor in summer is hot even when touched by hand. Direct sunlight absorbed the sun's heat. As a result, residents on the top floor, or residents of single-family homes, may have felt a lot of inconvenience. The ceiling that absorbs heat during the day does not cool down at night, but radiates it. This heat causes the interior space to be higher than the room temperature during the day and the air conditioner utilization rate increases nationwide.

The high heat of the ceiling, which was exposed to direct sunlight, will take away the heat from the ceiling surface due to the constant passing through the ceiling constant pipe (generally, the temperature is lower than the surface temperature), which will lower the temperature of the ceiling surface, thus lowering the room temperature. The operating time of the ceiling water supply pipe can be used according to the characteristics of the building and the user's purpose, so that it can be used in various ways. Figure 5. Comparison of buildings with normal ceilings and ceiling water pipes Two buildings that received sunlight (5-1) (left: general building, right: ceiling water pipes) have a large difference in room temperature. . The general building (5-2) exhibits a phenomenon in which indoor air is warmed due to heat convection caused by a ceiling exposed to direct sunlight for a long time, and a rise in room temperature occurs. Compared with 5-2), it can maintain the pleasant indoor space, and it can be double maintenance by reducing cooling cost and hot water heating cost. Whether cold air in the room is convection or hot air convection determines whether or not to increase or decrease the utilization of the air conditioner in the room. In the building with the ceiling water supply pipe, energy saving effect is maintained in the comfortable temperature even in the hot summer, and there is no difficulty in the management point.

 "Ceiling water pipes" can be used from early spring to late autumn, and in winter, especially during cold weather, damages may occur due to freezing of the ceiling water pipes. ) Turn off the ceiling water opening and closing valve and drain all the water from the ceiling water piping by using the drain valve (drain valve (2-8) in Fig. 2). This can be done once a year (before winter).

      The use of each building and the number of residents are applied to the general water usage calculation method, and the pipe size of the hot water tank ceiling water supply pipe and the size of the hot water supply pipe can be installed by applying the general calculation method.

By installing the above "ceiling water pipe", each family stays cool in summer (top floor)

It is possible to live, and hot water can be obtained by using natural energy (solar heat) rather than using a normal water consumption by running a fuel cost and operating a boiler.

If more buildings are installed with such "ceiling water pipes", the country's annual fuel consumption rate will be

It is expected to be considerably lowered and further contributing to the suppression of global warming.

It is important to use all the precious energy obtained from the earth and to reduce the environmental pollution of the earth, so it should be urgently applied to all buildings.
