High-efficiency energy-saving multipurpose solar water heater

Abstract

An efficient energy-saving and multipurpose solar water heater comprises a hot water storage tank, an evaporation water tank, a preheating water tank, a distilled water tank and a full glass double-vacuum solar collector tube, wherein a vapor heat exchanger and a domestic hot water exchanger are installed in the hot water storage tank; an assisting electrical heating pipe and a flow deflector areinstalled in the evaporation water tank; a distilled water exchanger is installed in the preheating water tank; a tap water inlet heat exchanger is installed in the distilled water tank; the tap waterinlet heat exchanger, the preheating water tank and the domestic hot water thermal exchanger are communicated with each other in sequence, so as to provide domestic hot water for users; the full glass double vacuum solar collector tube is communicated and connected with the evaporation water tank; and the evaporation water tank, the vapor heat exchanger, the distilled water heat exchanger and thedistilled water tank are connected and communicated with each other in sequence, so as to provide drinking distilled water for the users. The invention has the advantages of novel structure, high heat efficiency, energy conservation, multiple purposes and excellent technical performance.

Description

Technical field: [0001] The invention relates to a water heater widely used in human daily life, in particular to a high-efficiency, energy-saving and multi-purpose solar water heater. Background technique: [0002] As a clean and renewable energy source, solar energy has been widely used all over the world. Although my country's solar energy application technology started late, it has developed rapidly and has a strong momentum. It is mainly used in fields such as agriculture, electric power, chemical industry, heating, domestic hot water and seawater desalination. And only solar water heaters can really enter thousands of households, and solar cookers are difficult to enter families due to environmental limitations. Solar water heaters are favored by people for their energy saving, environmental protection, convenience and practicality, and low operating costs. However, the current solar water heaters still have the following deficiencies: first, the outlet pressure of h...
