Pressure-bearing wall hanging solar water heater without water tank

Abstract

The invention relates to a pressure-bearing wall hanging solar energy collector without a water tank. The solar energy collector is characterized in that the bottommost collector tube of the solar energy vacuum glass collector tube arranged transversely is connected to a cold water inlet pipe, and the upmost solar energy vacuum glass collector tube is connected to a high temperature hot water outlet pipe. Each solar energy vacuum glass collector tube is equipped with a long hollow metal water inlet pipe. Tap water flows into the solar energy vacuum glass collector tube through the cold water inlet pipe, then the warm water after heated by solar energy flows into the second solar energy vacuum glass collector tube, and the water heated by solar energy vacuum glass collector tubes one by one is output by the hot water outlet pipe. The solar energy collector provided by the invention has no water tank, has small volume, so that the collector can be installed on the balcony or outer wall transversely or longitudinally at each layer and each unit of a multilayer building without any noise. Meanwhile, the present solar energy collector has functions of heat collecting solar energy, thermal insulation and water storage, can bear water pressure from tap water. Hot water can be output very fast, no cold water is wasted, and cold water can be supplied automatically. The collector has no problems of idle sunning, frozen tube and tube explosion, because the glass vacuum glass collector tubes are always filled with water.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a pressure-bearing wall-mounted solar water heater without a water tank. Background technique [0002] Existing solar water heaters are placed on the roof of buildings, and all have water tanks. The hot water depends on the water level drop. The glass heat collecting tube of the water heater is not under pressure, and the water supply is cumbersome and overflows. At present, residential buildings are developing towards higher and higher levels, but it is only possible for top-floor residents to install it, and most owners cannot install and use it; because hot water depends on the water level difference, after turning on the hot water tap, there is no immediate hot water, so you have to wait After a few minutes, let off a large amount of cold water in the drop water pipe, just supply hot water, waste water resource, use hot water inconvenient.

[0002] Existing solar water heaters are placed on the roof of buildings, and all have water tanks. The hot water depends on the water level drop. The glass heat collecting tube of the water heater is not under pressure, and the water supply is cumbersome and overflows

At present, residential buildings are developing towards higher and higher levels, but it is only possible for top-floor residents to install it, and most owners cannot install and use it; because hot water depends on the water level difference, after turning on the hot water tap, there is no immediate hot water, so you have to wait After a few minutes, a large amount of cold water in the drop pipe is drained before hot water is supplied, which wastes water resources and is inconvenient to use hot water
