Problems solved by technology

When the sunshine conditions are not good, the water in the hot water storage tank is often not hot, and the water supply temperature cannot be guaranteed reliably; at the same time, the water tank of the general solar water heating device must be placed on the heat collector, which leads to the uncoordinated appearance of the building , and the existing technology is difficult to achieve reliable antifreeze, antifreeze
Since the basic temperature of the water supply cannot be reliably guaranteed, if the temporary use of other heaters not only increases the investment in a set of equipment, but also requires a long wait, which will naturally affect the normal use of the user and bring troubles to the user

Abstract

The invention relates to an all-weather dual-DC solar water heating system which is technically characterized in that solar heating is adopted to match with a conventional energy heating device for keeping the basic constant temperature of supply water, The all-weather dual-DC solar water heating system works in the following processes: leading out a water level signal, a water pressure signal and a water temperature signal to a controller after cold water and hot water of a heat storage water tank are mixed; controlling a cold water intake pipeline by the controller; communicating three parallel members with the water tank, a conventional energy heater and water points for switching work; leading out a hot water pipe from the water tank, driving the three communicated and parallel-connected members through a pump; and communicating to switch on or off the conventional energy heater, a solar heat collector and the water points. The working processes can be simultaneously operated or incompletely or cooperatively operated, a normally-open electromagnetic valve is connected with a solar water feeding pipe, a hot water return pipe and a water feeding morally-closed electromagnetic valve for synchronous switching. Every time the solar heat collecting process is over, water of the heat collector and water of the external pipeline are refluxed to the water tank in time. The invention radically solves the problems of freezing prevention and resistance, and the like.

Description

technical field [0001] The invention relates to an improved solar energy utilization and auxiliary heating device, in particular to a constant heat type all-weather double direct current solar water heating system which is suitable for supplying hot water at a constant temperature 24 hours a day. Background technique [0002] At present, the solar water heating device usually adopts natural circulation for heating, and the water heated by the solar heat collector is input to the hot water storage tank, stored and used. The temperature of the hot water produced in this way depends on the intensity of sunlight. When the sunshine conditions are not good, the water in the hot water storage tank is often not hot, and the water supply temperature cannot be guaranteed reliably; at the same time, the water tank of the general solar water heating device must be placed on the heat collector, which leads to the uncoordinated appearance of the building , and it is difficult to achieve ...
