Arrangement method based on dynamic balance unit technology in hot water heating system

Abstract

The invention discloses an arrangement method based on the dynamic balance unit technology in a hot water heating system. In the method, a backwater pipeline is connected to a boiler inlet end through a general heat network circulating pump; a boiler outlet end is connected by a water supply pipeline; the backwater pipeline of a general heating pipe network is connected to the boiler inlet end through a primary dynamic balance unit backwater over-current device and the general heat network circulating pump; the water supply pipeline is communicated with a water inlet of the input end of a heat exchanger through the primary dynamic balance unit backwater over-current device and a general water inlet circulating pump; and the backwater pipeline of the total heating pipe network is communicated with a water outlet of the input end of the heat exchanger through a general-grade balance valve, wherein a water outlet and a water inlet of the output end of the heat exchanger are respectively connected with a water supply pipeline and a backwater pipeline of a branched heating pipeline, a circulating pump of the output end is communicated in series to a backwater pipeline of the branched heating pipeline, an outlet end of a user heating pipe network is connected with the backwater pipeline of the branched heating pipe network through a secondary dynamic balance unit water backwater over-current device and a secondary balance valve, and a branched heating pipe network water inlet pipeline is connected with a user heating pipe network inlet end through a secondary dynamic balance unit water inlet over-current device and a circulating pump of the input end. The method reduces the flow of heat network dry pipe, reduces the designed pipe diameter of the dry pipe and saves the construction cost of the heat network.

Description

technical field [0001] The invention relates to a method for arranging a dynamic balance unit in an existing heating pipe network system, in particular to an arrangement method based on the technology of a dynamic balance unit in a hot water heating system. Background technique [0002] In the traditional heating system, it is customary to set the secondary circulating water pump at the heat exchange station (heat exchanger), and its function is not only the circulating water pump of the heat exchange station (heat exchanger) heating network, but also the circulating water pump of the secondary heating network. In the design and selection of circulating water pumps, the circulation flow is equal to the system design flow, and the lift is equal to the sum of heat source resistance loss, heat network resistance loss and end heat user's resource pressure head. The type selection of the water pump works in a large-flow operation mode, and a considerable surplus flow is also give...
