Description

Technical Field

[0001] The present invention relates to the technical field of household electrical appliances, and in particular to an intelligent control device and a control method for a hot water supply system applied to a public place. Background Art

[0002] As we all know, with the continuous updating of gas water heater equipment production technology, the requirements for hot water production efficiency of gas water heaters are also increasing. In small commercial scenarios, such as small hotels, swimming pools or other large households with large water demand, it is necessary to meet the bathing needs of multiple water points at the same time. Therefore, ordinary gas water heaters cannot achieve a large amount of hot water production. If you choose a traditional volumetric water heater or a compound hot water system, such equipment is large in size and has many auxiliary equipment, resulting in a large space occupation and complex installation and high maintenance costs. If you develop a high-power gas water heater, for example, a high-power appliance exceeding 70kW belongs to the category of commercial boilers, the development is difficult, the technical requirements are high, and the combustion conditions are unstable. And it is difficult to control the quality, so technical personnel in this field have developed a method of using multiple machines in parallel to design a gas water heater online device. Although the online method can effectively provide a large amount of hot water, it is necessary to add an additional controller, which has a complex structure, is inconvenient to install and control, and also increases the maintenance cost. Secondly, the online device adopts a control method of one main machine and multiple auxiliary machines. Due to the relationship between the main and auxiliary machines, if the main machine fails, it will affect the operation of the entire system, increase the after-sales maintenance cost and maintenance difficulty. Therefore, there is a need for a local online method, which ensures the safety and reliability of the online method through a dual online method, simple system installation, and low use and after-sales maintenance costs.
