Water-returning-free central water supply system capable of being heated instantly when opened and method thereof

Abstract

The invention relates to a water-returning-free central water supply system capable of being heated instantly when opened and a method of the central water supply system. The central water supply system comprises at least one gas hot water device. Inlets of the gas hot water devices are connected with a water inlet main pipe. Outlets of the gas hot water devices are connected with a water outlet main pipe. The water outlet main pipe is connected with multiple water outlet branch pipes. The water outlet branch pipes are connected with water inlets of electric water heaters. The electric water heaters are arranged in different floors or in different water consumption sites so that each floor or each water consumption site can be provided with one electric water heater. Outlets of the electric water heaters are connected with corresponding water pipelines of the sites where the electric water heaters are located. The central water supply system is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to a central water supply system and a method thereof which can be turned on and heated without returning water. Background technique [0002] Villa gas central hot water system, such as figure 1 As shown, one or more sets of gas-fired hot water equipment 1 are generally used, and the corresponding hot water storage tank 2 is configured to supply hot water. , the backwater pump 24 is installed on the backwater pipe, and the same or different journey pipeline system is used to realize instant hot water supply. The pipeline is long, the cost is high, the construction is difficult, and the construction period is long. Because the return water pipeline is long, the hot water is easy to cool. In order to ensure instant hot water supply, the gas-fired hot water equipment must perform uninterrupted hot water operation, which consumes a lot of energy. And once many people use it, the hot water supply will be insufficient, resulting in t...

AI Technical Summary

Problems solved by technology

The pipeline is long, the cost is high, the construction is difficult, and the construction period is long. Because the return water pipeline is long, the hot water is easy to cool. In order to ensure instant hot water supply, the gas hot water equipment must continue to perform hot water operation, which consumes a lot of energy.

And once many people use it, the hot water supply will be insufficient, resulting in the supply of cold water, and the user experience is poor
