Abstract

The invention provides an unpowered solar energy integration hot-water system which comprises an unpowered solar heat collecting and storing device, auxiliary heating equipment, a water supplementingand distributing pipe and a master control system. The unpowered solar heat collecting and storing device comprises a solar heat collection element and a heat exchange water tank; the auxiliary heating equipment comprises a gas stove, a hot water heat storing tank, an expansion tank, a gas stove circulation pump and a water return pump; the water supplementing and distributing pipe comprises a cold water supplementing pipe and a hot water distributing pipe; the cold water supplementing pipe is divided into a first cold water supplementing pipe body and a second cold water supplementing pipe body after being connected from a cold water supply source, and the first cold water supplementing pipe body is divided into a third cold water supplementing pipe body and a fourth cold water supplementing pipe body; and the hot water distributing pipe comprises a first hot water distributing pipe body, a second hot water distributing pipe body and a third hot water distributing pipe body. By meansof the unpowered solar integration hot-water system, cold water pressure enters the system to feed cold water into the unpowered solar heat collecting and storing device, and extra power is not needed.

Description

technical field

[0001] The invention relates to the technical field of building water supply equipment, in particular to a non-powered solar energy integrated hot water system. Background technique

[0002] With the development of society, energy shortage and environmental pollution have become the bottleneck restricting sustainable development, and the application of renewable energy has been paid more and more attention. As a relatively economical and relatively mature technology, ordinary residential solar water heaters have been used for several years, and domestic water heaters account for about 90% of solar thermal utilization; with the progress of urbanization, urban residences and public buildings are gradually designed and installed with solar water heating systems. Although it has been popularized and applied for nearly ten years, the concentrated solar water heating system generally has problems such as high investment, low efficiency, poor comfort, and difficult ...
