Hot water supply system combined with main heater and terminal heater and its control method

Abstract

The invention relates to a main heater and terminal heater combined hot water supply system and a control method thereof. The main heater and terminal heater combined hot water supply system comprises a main heater and one or more terminal heaters, wherein an inlet of the main heater is connected with a main cold water pipe; the main heater and a water distributor are connected through a main hot water pipe; branched hot water pipes are led out from the water distributor; the terminal heaters and cold and hot water mixing valves are in series connection through the branched hot water pipes; the terminal heaters are in parallel connection with by-pass pipes; and three-way valves are arranged at connection parts of the by-pass pipes and the branched hot water pipes. According to the main heater and terminal heater combined hot water supply system, inlet hot water and inlet cold water of the cold and hot water mixing valves are separately from the branched hot water pipes and branched cold water pipes, and the cold and hot water mixing valves are used for regulating the outlet water temperature; the terminal heaters are close to a water utilization site, and the water storage capacity is slightly larger than the water capacity of hot water pipes between the main heater and the terminal heaters; two modes of terminal heater independent water supply and main heater and terminal heater combined water supply can be selected according to the specific utilization condition of a user; and the system can timely output water, energy consumption caused by pipeline heat dissipation is overcome, the system is energy-saving and water-saving, and control is flexible.

Description

technical field [0001] The invention relates to a hot water supply system, in particular to a combined hot water supply system of a main heater and an end heater and a control method thereof. Background technique [0002] With the rapid development of my country's economy, the problem of energy shortage is becoming more and more obvious. At the same time, with the improvement of people's living standards, the consumption of domestic hot water is also increasing rapidly. How to reduce energy consumption on the premise of ensuring that people's quality of life is not affected has become a social concern. Due to the limitation of space and space, there is often a certain distance between the hot water point and the heater. When using hot water, it is often necessary to let off the cold water in the pipeline first, and it takes a long time to flow out the hot water. Not only is it inconvenient to use, but it also causes waste of water; and the temperature of the hot water rema...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the problem of wasting water and heat in the existing hot water supply system, and proposes a combined hot water supply system of the main heater and the end heater and its control method, which overcomes the problem when the water point is far away from the main heater. Hot water cannot be produced in time and the energy consumption caused by pipeline heat dissipation can be solved quickly, and hot water can be produced quickly without residual hot water in the pipeline
