Antifreezing solar water heating system and method

Abstract

The invention discloses an antifreezing solar water heating system and method. The antifreezing solar water heating system comprises a solar water heater. The solar water heater comprises a solar outer shell, a solar inner container and a solar end cover. The solar inner container is provided with an n-shaped groove. The n-shaped groove is internally provided with a three-way electromagnetic valve, a filtering cap and a flowmeter. The three-way electromagnetic valve is provided with a second three-way electromagnetic valve water inlet, a second three-way electromagnetic valve water outlet and a second air communication opening. The second three-way electromagnetic valve water outlet is connected with one end of a solar water outlet pipeline, and the other end of the solar water outlet pipeline is connected with a first three-way electromagnetic valve water inlet of the antifreezing three-way electromagnetic valve. The antifreezing three-way electromagnetic valve is provided with a first three-way electromagnetic valve water outlet and a first air communication opening. The first three-way electromagnetic valve water outlet is connected with a spray head and a valve through a pipeline. The valve is connected with an electric water heater through a pipeline. The electric water heater is connected with the spray head through a pipeline. The antifreezing solar water heating system and method have the characteristics of energy saving and environmental protection.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to an antifreeze solar hot water system and method. Background technique [0002] Solar energy is a non-polluting and sustainable energy that is currently available, and it is also free energy, so solar energy resources are used in many fields. In the field of water heaters, solar water heaters have always occupied a large market and provide great convenience for people's lives. However, it also has some shortcomings: First, in winter in many areas, due to the low external temperature, solar pipes are frozen and cracked. The bad phenomenon will cause the loss of users and affect the normal use; second, in the case of continuous rainy weather and insufficient sunlight time, the water temperature of the solar water heater will not meet the standard, which cannot meet the normal use of users. Contents of the invention [0003] The purpose of the present invention is to solve th...
