Metering control system and method for single-tube cocurrent heating mode

Abstract

The invention discloses a metering control system for a single-tube cocurrent heating mode, which is used for realizing the household metering and control adjustment of the single-tube cocurrent heating mode. The system comprises three-way valves, a temperature controller, a metering controller, a monitoring terminal, a regional heat meter and a network data collector, wherein the three-way valves are respectively arranged at an inlet of each radiator in a room of each heating user; the temperature controller and the metering controller are arranged in the room of each heating user, the temperature controller is used for obtaining the temperature set by the user and measuring the indoor temperature, and the metering controller is used for controlling the switching on or off of all the three-way valves in the room according to control signals sent by the temperature controller; the monitoring terminal is used for obtaining the heat value shared by each heating user; and the regional heat meter and the network data collector are arranged in a heating building or a heating unit, the regional heat meter is used for metering the total heat value used by all the hating users in the heating building or the heating unit, and the network data collector is used for receiving the accumulated starting time and the total heat value sent by the metering controller. The invention also discloses a metering control method for the single-tube cocurrent heating mode.

Description

technical field [0001] The invention relates to the field of urban heat supply, in particular to a metering control system and method of a single-pipe downstream heating mode. Background technique [0002] At present, the old-fashioned residential buildings in most parts of our country adopt the single-pipe downstream heating method. The furnace is a heating method in which the heat source, the heat source and the cooling equipment are set separately, and the heat source flows through the pipeline to supply heat to each room or building. The characteristic of the single-pipe downstream heating system is that all the water in the standpipe flows into the radiators on each floor in sequence, but this heating method does not have the ability to be adjusted individually. Due to the deviation in design and selection, the indoor temperature of the entire unit user cannot be adjusted. Balanced, there is a phenomenon of uneven cooling and heating among users, especially the large t...
