System and method for intelligent hot water circulation control and domestic solar water heater

Abstract

The invention discloses a system and a method for intelligent hot water circulation control and a domestic solar water heater. The system comprises an outlet water circulation pipeline connected with a water outlet of the solar water heater, a return water circulation pipeline connected with a water inlet of the solar water heater and a main controller. The outlet water circulation pipeline is provided with a flow sensor and a temperature sensor, and the flow sensor and the temperature sensor are used for sending water flow signals to the main controller when water flows in the pipeline. The return water circulation pipeline is provided with a water pump. The outlet water circulation pipeline is connected with the return water circulation pipeline through an electromagnetic valve. The main controller is connected with the flow sensor, the temperature sensor, the electromagnetic valve and the water pump, and is provided with a temperature control module and a time control module. The system, the method and the domestic solar water heater are wide in application range, high in practicality and efficiency, energy-saving and environment-friendly, users living in high-rise buildings and low-rise buildings can use solar water heaters, and hot water can be used conveniently at any time.

Description

technical field [0001] The invention relates to a hot water intelligent circulation control system, a method and a domestic solar water heater. Background technique [0002] Household solar water heaters are a common device that converts solar energy into thermal energy to meet the needs of hot water in people's lives. The existing solar water heaters have the following problems: the floors farther from the roof are longer because of the long pipelines, so the first time When using water, more cold water needs to be released, which has poor applicability, cannot meet the needs of users on low floors, reduces the application range of household solar water heaters, is not conducive to the extensive utilization of solar energy, and wastes water resources and energy. Contents of the invention [0003] In view of the above problems, the present invention develops a hot water intelligent circulation control system, method and household solar water heater with wide application ra...
