A method and system for realizing multi-unit parallel connection of gas water heaters

Abstract

The invention discloses a method and a system for the parallel connection of multiple gas heaters. The system is characterized in that a temperature sensor signal is received through an MCU (micro control unit), and a corresponding gas heater heating system, which is mainly composed of a plurality of hot water heaters connected in parallel, is initiated according to demanded hot water quantity and temperature. The system comprises a central controller, a constant temperature water tank and a gas heater generating unit the working state of which is controlled by the central controller. Water inlet and outlet pipes are connected between the gas heater generating unit and the constant temperature water tank, the constant temperature water tank is externally connected with a water point by a water booster pump and a circulation water pipeline. The system of the invention employs a PC as an operating unit to work out special software system, has the advantages of strong expansibility, convenience in installation and maintenance, simplicity in operation and energy conservation, and can be installed both indoors and outdoors.

Description

technical field [0001] The present invention relates to the technical field of a multi-machine parallel connection method for a gas water heater, and more specifically relates to a multi-machine parallel connection system for a gas water heater. Background technique [0002] At present, when the existing gas water heaters need a large amount of hot water, the hot water supply of a single gas water heater is obviously insufficient. In this case, it is necessary to combine multiple gas water heaters. For example, the Chinese patent application number is 200720049187.X , the name of the invention is a gas water heater on-line device, which includes a main water heater, a secondary water heater, a cold water inlet pipe, and a hot water outlet pipe. The main technical feature is that it also includes an inlet water temperature sensor, a water flow sensor, an outlet water temperature sensor, and a controller. The above water inlet temperature sensor and water flow sensor are respe...

AI Technical Summary

Problems solved by technology

This patented structure can effectively provide a large amount of hot water, but each water heater can only be turned on and off at the same time, resources cannot be optimally allocated, and energy is wasted. At the same time, the main water heater works for a long time. Once it fails, the entire system will be paralyzed. There is a demand for water, and it will be activated regardless of the size, which will greatly reduce the service life of the water heater, and it is not convenient to install and maintain
