The present invention relates to a boiler hot water distributor for heating. More specifically, the hot water distributor of a boiler used as a heating device is formed of a spherical polyhedron, but the hot water distributor is installed with a ball rotor inside the housing and rotated by a motor so that the heating is performed quickly, and the capacity of the boiler is increased. It can reduce heat and improve heat, and the ball rotor inside the housing can be matched only one side by 45 degrees to find the first setting point and can be driven to optimize, compact, versatility and practicality of hot water split supply. The present invention relates to an energy-saving heating hot water distribution device.

The traditional heating method of residential buildings in Korea has undergone many changes through the history of use for more than two thousand years and is an ondol of floor radiant heating method that has been used continuously. The biggest change in Ondol's transition is the emergence of a floor heating system that embeds pipes in the mid-1970s. The hot water heating system, which is developed and improved from our own ondol, is a radiant heating system, so it has high haptic temperature, saves fuel more than any heating system, cleans the indoor air, and has a high moisture content. As it is maintained, it is the most ideal heating method for home heating. Hot water heating system refers to a method of heating a room by embedding a pipe circulating hot water on the floor and supplying hot water to the pipe buried in the floor.

On-floor heating of floor radiant heating method provides soft and comfortable heating feeling, and it is already proved to be the best method in terms of heating performance and energy saving because it can get sufficient heating feeling at a relatively low room temperature compared to other heating methods. It is rapidly spreading to other countries such as Northern Europe, the United States, Japan, and China. In particular, after the introduction of the hot water heating system in Japan in the early 1980s, the floor heating method has been gradually used for home heating, and the hot water floor heating system has been widely used in northern Alps, which has a similar climate with Korea, such as Germany and Switzerland. .

The smooth split supply of hot water depends on the performance of the hot water distributor. The hot water circulation system and the constant flow automatic control method are used as the hot water distributor of the existing hot water heating system. These distributors are so large that they require a lot of installation space, and the number of pipes on the supply side and the return side increases depending on the number of branch ports, making construction difficult and excessively expensive construction and labor costs. ~ 1.8 million won) consumers are reluctant to use.

The hot water header refers to a device that distributes hot water produced by a heat source device to each room of a building without pressure loss and returns it. This can be achieved through management. In addition, one of the important factors in improving indoor comfort and energy saving in the hot water heating system is the technology that can accurately distribute the flow rate, and smooth hot water supply is dependent on the performance of the hot water distributor. Therefore, the hot water distributor must have the ability to additionally perform safety protection functions in addition to the technical functions of flow rate and temperature control.

The hot water heating system is classified according to the classification of hot water circulation method, hot water temperature, circulation pipe and circulation flow control valve according to the distribution method of hot water, and according to the structural form of the flow control valve on the valve of the hot water distributor for accurate flow control. Balancing, static flow control, automatic flow control and differential pressure control valve. As the hot water distributor 100 of the existing hot water heating system, a hot water distributor 110 of a hot water circulation method (see FIG. 1) and a constant flow rate control method (see FIG. 2) is used.

The hot water circulation method of Figure 1 is a low-cost method of heating by forcibly circulating the hot water by the pump of the heat source (boiler), while the differential heating according to the temperature of each room is difficult because the flow rate or differential pressure is not controlled at all, The constant flow rate control method of 2 is excellent in terms of differential heating and energy saving by the hot water split supply system so that the hot water circulated from the pump of the heat source is adjusted according to the temperature of each room to have a uniform temperature distribution for each room. Each branch port port on the hot water supply side and the return side has a problem that the price is about 5 to 20 times more expensive than the hot water circulation method because the flow control valve and the solenoid valve which is the valve operation driving unit are installed for flow rate control.

The present invention is to solve the above problems, first of all to look at the background to achieve the present invention in realizing the hot water distributor of the heating apparatus of the present invention, the heating method of the domestic residential building is almost the bottom radiant using low hot water The hot water split supply method, which is a heating method, is a concept of dividing the heat supply by supplying hot water to another ondol heating space while the ondol heating space is maintained at room temperature by the heat storage of the structure. It shows new energy saving potential as the heating method of apartment house in terms of the reduction of the size of the heat source equipment and the resource saving in the pipe equipment. However, in order to apply the hot water split-supply heating method to a real multi-family housing composed of many generations, it is necessary to solve the practical matters such as the problem of the area due to the difference in the heating load of the split-supply space and the comfort and the convenience of operation. Developed in consideration of economics and constructability.

Currently, multi-unit houses have a high weight structure, which has high heat storage properties.Increased insulation and improved airtightness ensure that the room temperature is not significantly affected by the outside air temperature. It is known to be possible. Therefore, the present invention utilizes such thermal properties, the hot water split supply method and the flow rate mixing method of supplying hot water to another heating space during the non-heating time when the room temperature is maintained by the heat storage of the structure can reduce the scale of the heat source equipment. It is invented to reduce heat related equipment and pipe materials of hot water, and to improve the efficiency of the system by reducing the partial load operation and stand-by loss of the heat source, thereby inducing heat loss and energy saving.

In other words, the smooth split supply of hot water depends on the performance of the hot water distributor. The hot water circulation system and the constant flow control method are used as the hot water distributors of the existing hot water heating system. These distributors are so large that they require a lot of installation space, and the number of pipes on the supply and return sides increases according to the number of branch ports. Consumers are reluctant to use it because it is difficult to construct, the construction cost and labor cost are excessive, and the fixed flow rate control method is too expensive.

The present invention is devised to solve the existing problems as described above, the object of the present invention relates to a hot water distribution device for heating by applying a hot water circulation method and a flow rate control method effective in energy saving and heating efficiency.

The present invention is to reduce the size to about 1/5 of the existing distributor to innovatively reduce the installation space to make the distributor into a six-octahedral shape, and to adjust the flow rate installed in each branch of the distributor for flow control in the existing heating system By simply integrating the valve and the driving unit of the rotor 1f, which is inserted into the distributor, by simply integrating the valve and the flow rate and flow path of each branch outlet, the integrated hot water distributor By reducing the size to about 1/5 ~ 1/6 and compact, the installation space is innovatively reduced, and the hot water distribution system of the conventional constant flow control type heating system is reduced by reducing the hot water conveying equipment and pipe materials. To provide a low to mid-priced hot water distribution system that is about 1/5.

The performance of the hot water distributor is in line with the internal pressure test (1,470 kPa) and the air tightness test (686 kPa), minimum flow rate (0.46 kPa), and the operating temperature of 60 ~ 70 ℃ as suggested by the hot water distributor performance standard (KS B6607) and ASHRAE standard. Based on the engineering basis, it was verified from computer simulations and the optimal design was made from these results to improve the efficiency of the hot water distributor.

Existing hot water dispenser uses a batch heating method that connects pipes to the ports of the distributor according to the number of rooms to be heated and heats all the rooms by the temperature set at the main controller installed in the living room or the main room (for example, 22 ℃). Adopted. Because of this, the boiler should be as large as the number of rooms or the size of the room, the heating time is also considerably longer, and even if the room temperature is the same, it is hot, such as the living room, where the sun is well-lit, and the door is open and the back room is not lit. There is a difficulty in the cold. In addition, the efficiency of the heating system is inevitably deteriorated due to the energy loss of the bulk heating and the hydrodynamic friction loss of the heating piping in each room.

Therefore, in this patent, the hot water distributor developed in the present invention to solve these problems is a hot water supply branch port installed on the surface of the distributor according to the flow path processed in the 45-60 ° direction to the ball rotor 1f and the set temperature of each room ( 6 ~ 8) to match one by one to achieve differential heating. At this time, the ball rotor is rotated by 45 ~ 60 ° by a motor installed in the distributor as shown in Figure 3 to exactly match the flow path of the rotor and each port of the distributor. When the heating temperature of the room reaches the set temperature according to the set temperature in each room, the branch port of the next room and the flow path are connected by the sequential method to start heating again. In this way, it is possible to reduce the size of the boiler (about 1/3 ~ / 15) rather than the conventional heating method because of the differential heating for each room, and reduce the load operation and stand-by loss of the boiler by one-to-one heating. By improving the thermal efficiency of the heating system, it is possible to make a significant contribution to energy loss as well as heat loss.

Therefore, the present invention smoothly and efficiently divides and supplies hot water, saves energy, improves thermal efficiency, reduces resources such as transportation-related equipment and surrounding materials, provides simplicity and compactness in construction, and provides versatility and practicality. It is an object of the present invention to provide a hot water distribution system that can maintain comfort.
