Project Overview
Shandong Lanxiang Senior Technical School
(formerly Shandong Lanxiang Technical School) is located in the north of the Second Ring Road, Tianqiao District, Jinan City There are 1 room in the newly built dormitory building on the road. In order to improve the accommodation conditions of students, the dormitory building uses a solar hot water system to supply hot water and preheat the boiler. The entire solar water heating project was installed and commissioned at the end of the year and put into operation after completion of the month and month acceptance. It has provided great convenience to students' lives and has been highly praised by teachers and students.

System Design
The heat collector of this project is installed on the roof of each dormitory building. The evacuated tube collector area has a total area of square meters. The hot water storage tanks are scattered on the roof of each building with a total capacity of tons.

Characteristics of the design plan
It is rare to see such a large-scale use of solar water heating systems in private technical schools in our country. It provides a model for other similar schools to use solar water heating systems. The original roof design of this project was designed to have an upper roof without affecting the function of the roof. The heat collector was designed to be installed on the roof flower stand, which provided a reference for the integrated design of solar energy and building.
Since the school’s water use time is relatively fixed, the antifreeze system uses a combination of pipeline circulation and electric heating tape, with circulation antifreeze as the main antifreeze method and electric heating tape as a supplement to ensure the normal operation of the system.
