How to make solar hot water scheme

Solar energy hot water engineering scheme includes solar energy hot water engineering installation scheme and solar energy hot water engineering pipeline installation scheme.

Solar hot water engineering Installation Scheme

The installation of solar hot water engineering should consider the factors such as firm fixation, structural safety, windproof, lightning protection and roof drainage.

Fixed on the roof waterproof layer to prevent roof leakage caused by destroying the waterproof layer.

Concrete method: concrete piers are directly poured on the roof, and expansion bolts are embedded in the piers. Pier position: Pier should be located above the structural wall. It is forbidden to fall directly on the floor (it is easy to overload and cause floor deformation and leakage). The pier size is determined according to the local wind load after wind resistance checking. In order to increase the stability, it is advisable to cast multiple households into a combined pier. Drainage holes are reserved on the pier to ensure smooth roof drainage.

Safety measures for lightning protection of solar energy hot water engineering

Solar water heaters installed on the roof generally exceed the height of the parapet on the roof, so the original lightning protection system on the roof is invalid for solar water heaters. Lightning protection measures should be considered in buildings with solar water heaters installed in the later stage.

For buildings with solar energy installed in the design stage, measures such as fixation and lightning protection should be considered in the design.

Installation scheme of solar energy hot water engineering pipeline

Pipeline installation of solar hot water system and auxiliary hot water system is an important part of auxiliary hot water system. Including pipeline material selection, pipeline laying and pipeline insulation.

Pipe selection: Aluminum-plastic composite pipe is recommended for solar water heaters. Don't use hoses and PP-R pipes, because these pipes are deformed and difficult to fix.

Pipe laying: The water pipe laying of solar water heater should be a special through-wall pipe or tube well. Pipe holes or wells should be reserved, and pipes should be fixed with pipe fixing clips.

Pipe insulation: hot water flows into the room from the roof and has to go through a certain distance. The longer the pipeline, the greater the heat loss along the way. Therefore, heat preservation measures must be taken for pipelines. For pipes covered with caves, a layer of thermal insulation material should be wrapped on the pipes. For the laying method of special pipeline wells, thermal insulation materials such as expanded perlite can be filled in the pipeline wells.

It is best that the pipes supporting the solar water heating system can be uniformly supplied by the manufacturers. The pipeline is directly made into thermal insulation pipeline, which increases the flexibility and adaptability of installation and reduces the workload of on-site installation and thermal insulation.
