Description

[0001] The present invention relates to a hot water and a heating pipe system,

[0001] The present invention relates to a high-temperature water piping system for collective energy secondary, and more particularly, to a system for supplying high-temperature water through a supplementary pipe, The heat source is not taken away from the outside, and the heat quantity is not lowered. As a result, it is not necessary to separately form a water pipe to the machine room in order to supplement the high-temperature water with water, thereby reducing the facility cost, construction cost and construction period Collecting energy secondary side hot water piping system.

Recently, a large apartment or a large-scale building has not only an individual heating system and a separate hot water supply system, but also installed a common heating system for the whole, and supplies hot water to each household or each floor through a common pipe network. The system is constructed with a central supply system that supplies water to each household or each floor through a pipe network after heating the water to the appropriate temperature through heat exchange between the hot water and the water supply.

This centralized supply system can deal with the reduction of the efficiency of the equipment over the years compared to the individual method by using the highly efficient heat source equipment and managing it as the manager with the specialized technology, and applying the simultaneous utilization rate It has the advantage of reducing the total capacity of the equipment and collecting firepower in one place, which makes it easy to respond to emergencies such as fire.

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.

Also, in the conventional four-pipe type centralized heating system, when hot water is not supplied during the summer season, only hot water for hot water is supplied, so heating can not be used.

As shown in FIG. 2, in order to replenish the hot water to be supplied when the hot water is supplied, a separate water pipe 7 is formed from the outside to be supplied. At this time, And the water replenishment is connected to the water return pipe 4-2 in the machine room 1 to increase the cost and installation time due to the installation of the separate water pipe 7 And the hot water conveyed from the water return pipe 7 in the machine room 1 passes through the outside, and thus there is a problem that a large amount of heat loss occurs and the amount of heat is reduced.

To a hot water piping system.

As described above, in the collective energy secondary hot water piping system of the present invention, the water is transferred to the hot water collection pipe through the supplement pipe in the building where the hot water is supplied, so that the temperature (ΔT) Is lowered in advance.

In addition, it is possible to reduce the equipment cost, the construction cost, the construction period, and the like by eliminating the formation of the water pipe separately to the machine room so as to supplement the constant water to the existing high temperature water.
