Embodiment 1

[0038] figure 1 It is a flowchart of a control method for a water heater based on solar energy and air energy according to Embodiment 1 of the present invention. Such as figure 1 As shown, the method includes:

[0039] Step S102, obtaining the variation degree of solar energy of the solar water heating system;

[0040] Step S104, adjusting the heating operation time of the air energy water heating system according to the obtained solar energy variation degree, wherein the solar water heating system is in the first preset time t 1 The amount of hot water produced is the same as that of the air energy hot water system at the second preset time t 2 The sum of the amount of hot water produced is equal to the amount of hot water preset by the user.

[0041] Through the above processing steps, when adjusting the running time of the air source water heating system, because the solar energy variation degree of the solar water heating system is considered, it can solve technical pr...

Embodiment 2

[0067] The purpose of this embodiment is to propose a method of control and coordination to improve the adaptability of the combination of solar energy and air energy, so that the number of solar collector tubes installed is determined according to the specific available area, and combined with air energy to meet the needs of users for hot water. demand. Furthermore, it can solve how the solar energy system can timely and effectively detect rainy weather or insufficient light, and make a response to control the opening of the air energy system to ensure the water consumption of users.

[0068] ① The amount of water V required by the user is the size of the hot water storage tank, and the amount of hot water that can be produced by solar energy in normal weather is V 太 , accounting for θ of the water volume in the tank. The air can work for one day (8 to 10 hours) and the amount of hot water that can be produced is V 空 , the air can work for a day t 2 hours (t 2 It is the h...

Abstract

The invention provides a control method and device for a water heater based on solar energy and air energy. The control method comprises the steps of obtaining the solar energy variation degree of a solar energy water heating system, and adjusting the heating operation time of an air energy water heating system according to the obtained solar energy variation degree, wherein the sum of the hot water quantity obtained by the solar energy water heating system within a preset time t1 and the hot water quantity obtained by the air energy water heating system within the preset time t2 is equal to the hot water quantity preset by a user. According to the technical scheme, the control method and device for the water heater based on solar energy and air energy saves the control cost of the water heater based on solar energy and air energy, and effectively saves power resources.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a control method and device for a water heater based on solar energy and air energy. Background technique [0002] At present, the control method of the more advanced solar water heating system and the air energy water heating system is as follows: [0003] The configuration of the system: supplementary cold water system, solar system (or called solar collector and solar hot water system), solar cycle heating water tank, hot water storage tank, air energy heat pump auxiliary system (or called air energy system and air energy hot water system), regular water supply system. [0004] Wherein, the capacity of the solar circulation heating water tank is less than the hot water (about 1 / 5) that the solar collector can produce in one day under normal weather conditions. There is a set of temperature sensors in the hot water storage tank, a thermostat with the function of automatical...
