Embodiment 1

[0046] In order to overcome the shortcomings of the existing centralized pipeline network transmission and distribution application, the purpose of this embodiment is to provide a cold and heat source circulating pump in the building's decentralized pipeline network transmission and distribution system. Four graded mixed water pump user units are installed in the building, which solves the problem of high lift and power consumption of the cold and hot circulating water pump in the cold and heat source machine room existing in the existing centralized pipe network transmission and distribution technology; throttling in the building The valve consumes a lot of power consumption of the pipe network, resulting in excessive flow supply at the front end of the pipe network and insufficient flow supply at the end of the pipe network, resulting in hydraulic imbalance of the pipe network, resulting in loss of cooling and heat transmission and distribution, and waste of electric energy. ...

Embodiment 2

[0082] On the basis of Embodiment 1, the distributed pipe network transmission and distribution system in the building of this embodiment includes: cold source or heat source, general transmission and distribution water supply pipe network, general transmission and distribution return water pipe network, at least one set of first classification The user unit of the water mixing pump, at least one group of the user unit of the second graded water mixing pump, the terrain height h1 of the user unit of the first graded mixed water pump installed in the building>the terrain height h2 of the user unit of the second graded mixed water pump installed in the building;

[0083] Each user unit of the first-stage mixed water pump and each user unit of the second-stage mixed water pump are set in parallel, and each user unit of the first-stage mixed water pump and each user unit of the second-stage mixed water pump are respectively connected to the main transmission and distribution water s...

Embodiment 3

[0109] On the basis of embodiment 2, with reference to image 3 As shown, this embodiment discloses the structure of the user unit of the first graded water mixing pump. The first user unit of the graded water mixing pump includes: a first water mixing pipe installed between the first water supply pipe and the first return water pipe, and a first graded pump and a first water mixing pump installed on the first water supply pipe;

[0110] One end of the first water mixing pipe is arranged on the first water supply pipe between the first grading pump and the first water mixing pump, and the first grading pump provides power for the total transmission and distribution of water in the first water supply pipe network to the first water supply pipe, The first water mixing pump mixes the water in the first water supply pipe and the return water in the first return water pipe to a temperature required by the user, and then supplies the water to the user. This embodiment only needs to...

Abstract

The invention provides a distributed pipe network transmission and distribution system in a building. The system comprises a cold source or a heat source, a main transmission and distribution water supply network, a main transmission and distribution water return network, at least one group of first stage pump and water mixing pump unit for users and at least one group of second stage pump and water mixing pump unit for users, wherein the terrain height h1 of the first stage pump and water mixing pump units installed in the building is greater than the terrain height h2 of the second stage pump and water mixing pump units for users installed in the building; each first stage pump and water mixing pump unit for users and each second stage pump and water mixing pump unit for users are arranged in parallel, and each first stage pump and water mixing pump unit for users and each second stage pump and water mixing pump unit for users respectively form a circulation loop with the main transmission and distribution water supply network, the main transmission and distribution water return network, and the cold source or the heat source. Different stage pump and water mixing pump units forusers are arranged in the building, so that the problems of high lift and high power consumption of a cold and heat circulating water pump of a cold and heat source machine room in the conventional centralized pipe network transmission and distribution technology are solved.

Description

technical field [0001] The invention relates to the field of pipeline network transmission and distribution systems, in particular to a decentralized pipeline network transmission and distribution system in buildings. Background technique [0002] In the past few decades, the transmission and distribution methods of cooling and heating in my country have all adopted centralized transmission and distribution systems. The problems of centralized cooling and heating pipeline network transmission and distribution systems have become more and more serious in terms of system design, operation and debugging. It is becoming more and more prominent, mainly because the centralized pipeline network transmission and distribution system is designed with the main circulation pump set at the cold and heat source, and its head is determined according to the pressure loss of the most unfavorable loop. If the pressure is too high, the flow is too much; if the pressure of the remote user is too ...
