The integrated district heating pipe system with individual hot water supplying unit in household of apartments}

The present invention relates to an integrated heating system for district heating using a hot water supply heat exchanger in a household, and more specifically, to install heating and hot water supply piping as an integrated pipe, and install only the integrated pipe and a recovery pipe to manage construction cost, facility construction cost, and facility management. And maintenance costs are relatively reduced, and the heating water, which passes the hot water heat exchanger and heats the hot water, is not returned to the main integrated heat exchanger as it is, but is circulated to the hot water distributors or floor coils installed on each floor or floor. The use efficiency of the heating water supplied by the power supply is increased, and the occurrence of heat loss lost in the process of circulating the heating water to the main integrated heat exchanger is minimized.The main integrated heat exchanger is installed at all times to supply the heating water, Or by installing hot water heat exchangers for each floor regardless of season Heating, cooling, and hot water can be freely used to provide convenience to the user. Cold water and hot water are supplied to the water supply through one hot water supply pipe, compared to the piping system that was previously installed with two supply pipes. The present invention relates to an integrated piping system for district heating using a hot water supply heat exchanger in a household, in which cost can be reduced and construction time of one hot water supply pipe can be shortened and workability can be greatly improved.

In recent years, apartment complexes and medium-sized buildings have been equipped with common heating facilities for the entire complex, rather than individual heating and individual hot water supply systems, and supply heating hot water to each household or floor through a common pipe network. The system is constructed by a central supply system that supplies water to each generation or floor through a pipe network after heating the water to the appropriate temperature through the heat exchange between the hot water and the water supply.

This central supply method uses a relatively efficient heat source device and manages it as a manager with specialized skills, so that the central supply method can actively respond to the decrease in efficiency with the age of the device compared to the individual method, and the simultaneous use rate is applied. It is easy to cope with emergencies such as fire by reducing total device capacity and gathering fire power in one place.

As shown in FIG. 1, the centralized heating system includes a circulation pump 2 for circulating high temperature water in a heat production facility 1 for producing high temperature water. The hot water pipe 5 is connected to the circulation pump 2 through the heat exchanger 3 for heating and the heat exchanger 4 for supplying and recovering hot water to or from the building A .

The heating heat exchanger 3 is provided with a heating supply pipe 3-1 and a heating return pipe 3-2 connected to the respective generations and rooms and the hot water supply heat exchanger 4 is provided with hot water A supply pipe 4-1 and a hot water supply return pipe 4-2 are installed. That is, it is a 4-pipe system.

However, in the conventional 4-pipe type centralized heating system, there are problems in that construction cost, facility construction cost, facility management and maintenance cost are increased in order to install each piping, and a large number of piping installation causes heat loss There is a problem that this occurs.

In addition, the conventional four-pipe type of central heating method has a problem that heating is not available because only hot water is supplied when heating hot water is not supplied in summer.

Rather than return to the main integrated heat exchanger, the efficiency of use of the heated water is increased by circulating the hot water distributor installed on each household or floor by floor or directly to the floor coil. The purpose is to provide an integrated piping system for district heating using hot water heat exchangers in households, which minimizes the loss of heat lost in the process.

In addition, by installing the main integrated heat exchanger to supply heating water at all times and by installing the hot water supply heat exchanger for each household or each floor, heating, cooling and hot water supply can be freely used for each household or floor regardless of the season. Another purpose is to provide an integrated piping system for district heating using in-generation hot water supply heat exchangers.

In addition, by supplying the cold water and hot water to the water supply through one hot water supply pipe, the cost is reduced compared to the piping system that was previously installed by installing two supply pipes, and the work time is shortened by constructing one hot water supply pipe. Of course, there is another object to provide an integrated piping system for district heating using hot water heat exchanger in the household, which can greatly improve workability.
