Furthermore, since the water heater in this embodiment is not connected to the atmosphere, and can constitute a closed system, and thus is not polluted by the outside, the hot water supply system of the multi-story building provided in this embodiment can be free from cleaning, maintenance, and the like, and further, since the water heater is installed on the top of the multi-story building, such as a villa or an apartment, it can be far away from the areas such as bedrooms, living rooms, and the like, so as to avoid the influence of noise generated by the water heater on the owners. It should be noted that, in the present embodiment, only the multi-storey building is taken as an example of the villa.

Through this structure, make from the hot water of water heater to each water appliances supply, only need flow through partial hot water supply main pipe, the floor hot water that corresponds is responsible for and the hot water branch pipe of floor can, therefore, the pipeline of flowing through is shorter, thereby make hot water follow the pipeline and flow the heat that causes and power loss and want much littleer, the temperature drop is less, water pressure has sufficient assurance, not only energy-conservation, and make the temperature of each water appliances output higher, water demand that can be different, for example warm water is washed one's hands, wash one's face, wash one's dishes or requirement such as bathing, user's water experience has greatly been promoted.

Through the structure, the water return pipeline assembly conveys the low-temperature water in the recyclable hot water loop back to the water heater, the conveyed hot water flow is less than that of the main pipe, and therefore the heat loss is lower.

In order to meet the design and installation requirements in practical application, the diameter of the pipeline of the water return pipeline assembly is less than or equal to DN 20.

Further preferably, the water return line assembly includes: a plurality of steel pipes or composite pipes which are connected in sequence and have the diameter of DN15, so that the quantity of hot water flowing through the water return pipeline assembly is very small by adopting the minimum size as the pipeline of the water return pipeline assembly, and the energy consumption is reduced to the maximum extent.

Further preferably, the pipe diameter of the hot water supply main pipe 1 is larger than that of the floor hot water branch pipe assembly. So that the amount of water in the hot water main pipe 1 is enough to meet the water supply requirements of each layer of hot water branch pipe assembly.

For example, the number of toilets is selected: when the number of the toilets in the multi-storey building is 3-4, DN25 pipes are preferably used as the pipelines of the hot water supply main pipe 1 and the cold water supply main pipe 2; when the number of the toilets in the multi-storey building is 5-6, DN32 pipe is preferably used as the hot water supply main pipe 1 and the cold water supply main pipe 2; when the number of toilets in the same floor of a multi-floor building is within 2, DN20 pipes are preferably adopted as the pipelines of the floor hot water main pipe and the floor cold water main pipe; when the number of toilets in the same floor of a multi-floor building is within 3-4, DN25 pipes are preferably adopted as the pipelines of the main floor hot water pipe and the main floor cold water pipe. Here, it should be noted that fig. 1 is a schematic cross-sectional view of a multi-story building, and therefore, the water-using devices in different rooms on the same floor may be connected to each other through an optimal laying route by making the pipe route of the floor hot water main pipe and the floor cold water main pipe straight along the horizontal plane, or by designing the pipe route to have any shape such as an L shape, a bent shape, or a zigzag shape according to actual circumstances.

In general, the thermal conductivity of cement mortar walls, brick walls and the like is more than 10 times that of air, so that the hot water supply main pipe 1 and the hot water main pipes of each floor are not embedded into the walls of multi-storey buildings, so that the aggravation of heat loss caused by the fact that the thermal conductivity of the walls is far greater than that of the air can be avoided, and a good energy-saving effect can be achieved. Because above-mentioned hot water supply main pipe 1, return water are responsible for 3 and the return water main pipe 4 and all set up in the pipe-line well, and each floor hot water that corresponds is responsible for and sets up inside the furred ceiling, not only do not influence the decorative effect in the multilayer building, but also be favorable to the maintenance that above-mentioned hot water supply main pipe 1, return water are responsible for 3 and return water main pipe 4 and each floor hot water are responsible for.

In addition, it is worth mentioning that the hot water insulation jacket in the embodiment is preferably a rubber plastic protective jacket.

Further preferably, each floor hot water branch pipe of the floor hot water branch pipe assembly is embedded in a wall body of the multi-story building. Because the hot water main pipe of floor in this embodiment installs above the furred ceiling, can reduce the length of the hot water branch pipe of embedding in the wall, because it receives the restriction of room size, usually the length is only 3-5 meters, consequently, when opening the hot water valve with the water apparatus, only need 3-5 seconds can discharge the low temperature water of hot water branch pipe fast, then the velocity of flow of the suitable hot water of quick outflow temperature can reach about 1 meter per second, so it is very good to experience with the water.

The cold water stratification valve may be embodied as described in fig. 1 with reference to the cold water stratification valve 61 located in the first floor, the cold water stratification valve 62 located in the second floor, and the cold water stratification valve 63 located in the third floor, etc.

In order to meet the assembly and maintenance requirements in practical application, each hot water stratification valve is preferably arranged adjacent to the connection between the floor hot water branch pipe assembly and the hot water main supply pipe 1. Each cold water layered valve is arranged near the connection of the cold water branch pipe assembly of the floor and the cold water supply main pipe 2.

Example two

The present embodiment provides an upper heating water supply pipeline of a multi-storey building, which is a further improvement of the above embodiment, and the improvement is that as shown in fig. 3, the upper heating water supply pipeline further comprises: and the circulating pump 8 is arranged in the water return pipeline assembly and positioned at the top. Wherein the top upper side is preferably on the roof surface of the house shown in figure 1.

Through this overall arrangement for when circulating pump 8 starts, can promote hot water and flow in the circulated hot water return circuit of above-mentioned formation, need not open the layering return water pump and can make the low temperature water in each floor hot water main pipe flow back to water heater 10 in reheating through the return water pipeline subassembly, in order according to the actual conditions of difference, play energy-conserving effect. The hot water circulating system is arranged on the roof of the house, so that the hot water can be pushed to flow only by providing small power, power can be saved, in addition, the maintenance and the repair of the circulating pump 8 can be facilitated due to the arrangement of the hot water circulating system on the roof of the house, and the normal circulation of the whole hot water supply pipeline is not influenced even if a single layered water return pump fails, so that the water consumption of a user is ensured.

The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit the same, and the present invention is described in detail with reference to the preferred embodiments. It should be understood by those skilled in the art that various modifications and equivalent substitutions may be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention, and the scope of the claims of the present invention should be covered thereby.
