Abstract

The invention discloses a water heater hysteresis temperature adjustment method, a water heater control method and a system. The water heater hysteresis temperature adjustment method includes obtaining a pipeline length parameter, and obtaining a standard hysteresis temperature according to the pipeline length parameter; detecting an ambient temperature parameter, and according to the The hysteresis temperature correction amount is obtained from the ambient temperature parameter; the final value hysteresis temperature is calculated according to the standard hysteresis temperature and the hysteresis temperature correction amount. In this technical solution, the final hysteresis temperature used to judge whether the water heater needs to end the preheating process is modifiable according to the ambient temperature parameters and the pipeline length parameters, which can ensure that the water heater meets the preheating requirements and avoid the failure of the water heater to terminate the preheating. The state of the process occurs.

Description

technical field [0001] The present invention relates to the technical field of water heaters, and more specifically relates to a water heater hysteresis temperature adjustment method, a water heater control method and a control system using the hysteresis temperature adjustment method. Background technique [0002] When the zero-cooled water heater preheats the water in the pipeline, it judges whether it is necessary to end the preheating process based on the detected inlet water temperature. When the water heater detects that the inlet water temperature is lower than a certain value of the set temperature, It is considered that the preheating requirement is met, and the preheating process needs to be ended, and a certain value above is defined as the hysteresis temperature. At present, the hysteresis temperature of various zero-cooled water heaters on the market is set as a fixed value that cannot be modified. [0003] In practical application, the zero-cooling water heate...

AI Technical Summary

Problems solved by technology

[0003] In practical applications, the zero-cooling water heater needs to be matched with a certain length of pipeline. When the zero-cooling water heater is preheated, due to the heat loss when the water flows in the pipeline, the total amount of heat loss is related to the length of the pipeline and the ambient temperature. , so if the hysteresis temperature of the zero-cooled water heater cannot be adjusted, it is very likely that the preheating time will be too long, or even the preheating requirement will never be met.
