Supplemental solar energy-saving water heater for high-rise building

Abstract

The invention relates to a solar water heater, in particular to the solar water heater for a high-rise building, and the solar water heater belongs to the field of solar heat supplying systems. The device mainly consists of a solar heat-collecting plate, a hot water tank and a water conveying pipeline, a hot water main pipeline from the roof to users who live downstairs adopts a polypropylene laminated vacuum thermal insulation pipe, a series of auxiliary downstairs solar heat-collecting plates are arranged on downstairs sunny regions or balconies of the users and connected onto the vacuum thermal insulation pipe through a circulating hot water pipe and a cold water pipe, and the users of the whole high-rise building can obtain hot water by the thermal insulation feature of the vacuum thermal insulation pipe and the supplemental heating by downstairs heat collectors. The solar water heater has simple structure, low cost and small occupied area, and can carry out thermal insulation and heating on a main heat supplying pipe and solve the problem of heat dissipation of residual water.

Description

technical field [0001] The invention relates to an energy-saving bottom balcony wall-mounted heat collector and a hot water vacuum insulation tube heat collector. It belongs to the field of energy saving and emission reduction. Background technique [0002] High-rise and small high-rise buildings account for an increasing proportion of urban construction and development. Due to the small roof area, people used to think that it was difficult to place solar collectors. If solar water heaters are installed on high-rise and small high-rise buildings, the average solar heating area of ​​each household is small. In addition, the distance between the water outlet of the hot water tank and the hot water pipes between the users is more than ten to hundreds of meters. When users use hot water for the first time, they have to release a lot of residual water, which not only causes a lot of waste of tap water resources, but also is very inconvenient for users to use. It also causes a lo...

If solar water heaters are installed on high-rise and small high-rise buildings, the average solar heating area of ​​each household is small. In addition, the distance between the water outlet of the hot water tank and the hot water pipes between the users is more than ten to hundreds of meters. When users use hot water for the first time, they have to release a lot of residual water, which not only causes a lot of waste of tap water resources, but also is very inconvenient for users to use. It also causes a lot of waste of heat energy while releasing water. The traditional solar water heater pipeline system is adopted It is simply impossible to provide hot water to users on the entire floor, so the engineering application of solar energy in high-rise buildings is almost blank, and most solar energy companies are "fearful of heights".
