Embodiment Construction

[0016] like figure 1 As shown, the water heating device of the solar water heater includes a vacuum heat collecting tube (not shown in the figure), a water storage tank 1, a steam generating box 2, a replenishing water tank 3 and a water tank shell 4, and the vacuum heat collecting tube passes through the installation hole 5 and the water storage tank 1, The steam generating box 2 is connected. The water storage tank 1 and the steam generating tank 2 are arranged in the same water tank shell 4, and both are connected through a water vapor introduction pipe 6 and a return pipe 7. The water ratio of the vacuum heat collecting tubes connected with the steam generating box 2 is smaller than that of the vacuum heat collecting tubes connected with the water storage tank 1 . For example: the water ratio of the existing all-glass vacuum heat collecting tube is generally 8.4 liters for one φ58-1800, if a φ58-1800 is matched to 4.2 liters, the heat generated by the vacuum heat collecti...

Abstract

The invention discloses a kind of heating method of the solar energy water heater and its heating equipment. It adopts the vacuum collector and the water vapor at the same time as the heat source and heat the water in the storage water tank. The water vapor is generated by using the vacuum collector to heat the water in another vapor generating tank at the point of boiling and then it is lead to the storage tank of solar water heater. The invention makes the single colleting system of present solar water heater (single heat way) changed into the dual colleting system (dual hest way) at the same meaning is that the steaming thermal system and the common vacuum collector system. It adopts the method of running the two supplying heat systems at the same time so it improves the received thermal efficiency of the solar energy water heater and accelerates improving the water temperature in the storage water tank and resolves the problem of adopting the needed hot water is little for the solar energy water heater in winter and improves the utilization efficiency of water heater.

Description

technical field [0001] The invention relates to a water heating method of a solar water heater and a heating device thereof, in particular to a water heating method and a heating device of a solar water heater using a vacuum heat collecting tube and water vapor as heat sources at the same time. Background technique [0002] As an energy-saving and environment-friendly product, solar water heaters have been widely used in people's daily life and have become an essential facility for more and more families. With the development of the economy and the continuous improvement of the living standards of the people, the use of solar water heaters is also increasing, and the requirements are getting higher and higher. The solar water heater generally used at present has only one heat collecting system (being vacuum heat collecting tube), and the water in the water tank can only be heated by the vacuum heat collecting tube. Due to the different ambient temperatures in spring, summer...
