A control method for a multi-energy water heater and the water heater

Abstract

The invention discloses a multiple-energy water heater and a control method thereof. The multiple-energy water heater comprises a water tank, a solar heating system, an auxiliary heating system and a control system, and the water heater is provided with an appointment function. The control method includes: judging whether an appointment can be performed or not; the control system judging whether or not water in the water tank can be heated to appointed temperature when time is appointed by using the auxiliary heating system independently, if not, not allowing a user to make an appointment, and if yes, allowing the user to make the appointment; judging whether the auxiliary heating system is started or not; after appointment is made, starting the auxiliary heating system to have the water in the water tank to be heated when the water in the water tank can be just heated to the appointed temperature in remaining time of the appointment by using the auxiliary heating system independently. With the method, whether or not the user can make the appointment can be judged according to the appointed time and appointed temperature, the user is prompted if the appointment cannot be made, utilization among multiple energies can be controlled reasonably according to the appointed time and appointed temperature, energy sources can be reasonably utilized, and requirements of the user can be guaranteed.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a control method for multi-energy water heaters, which reasonably controls the use of various heating systems, maximizes the use of solar energy and ensures the water temperature of users. Background technique [0002] Solar energy is a mature clean energy, and its use is very popular, but the problem is that it is affected by the weather, and sometimes it cannot meet the real-time hot water demand. Most of the multi-energy water heaters currently on the market use a simple combination of solar energy and gas or electric water heaters, that is, after preheating water with solar energy, other energy sources are used to heat the preheated water to achieve energy saving. When the weather is not very good, the solar energy has a poor preheating effect on water, and the heating efficiency of the combined water heater is not high. How to control the rational use of various energy sources ...
