The Tumushuke City Thermal Secondary Pipeline Balancing Project has 18 heat exchange stations and 24 residential areas, with a total of 1,942 IoT balancing valves, 1,942 heat meters, and 3,884 room temperature collectors installed. The total heating area is 3.4 million square meters, and the renovation area is 2.26 million square meters.

The renovation area is 2,000 square meters, and the renovation content adds intelligent control valves (120 units) and soil trace element collectors (56 sets). The first unmanned operation, mobile phone APP remote operation, 4 planting sheds fully use diversified irrigation (drip irrigation, sprinkler irrigation, flood irrigation). Save 30 tons of water per month and save 500,000 yuan in labor costs The project realizes intelligent irrigation time-sharing control

Shandong Technician College: The college covers a total area of ​​more than 1,600 acres, with a building area of ​​225,000 square meters, of which the renovated heating area is about 100,000 square meters. It adopts the Navico time-sharing and zone-controlled energy-saving system, boiler DCS control system, unattended heat exchange station control system, heat network dispatching system, and pipe network balance system, saving 900,000 yuan in annual heating costs and saving

The Shandong University project is divided into five renovation projects according to the campus, namely the Xinglongshan Campus Project, the Qianfoshan Campus Project, the Baotuquan Campus Project, the Hongjialou Campus Project, and the Central Campus Project, with a total renovation area of ​​1.76 million square meters. The renovation content includes the intelligent control management system and the time-sharing and zoning control system. Through the intelligent control and time-sharing and zoning system renovation, the hydraulic imbalance problem of the pipeline network is solved. At the same time, the control is divided into time periods and regions, which greatly saves energy and reduces emissions. The energy saving rate is 21%. In addition to the above colleges and universities, so far, our company has also carried out project renovations for Langfang University Town, Shandong Technician College, Shandong Jiaotong College, Tianjin Maritime Vocational College, Jinan Urban Construction College, Shandong Normal University, Laiwu Vocational College, Linfen Heating Company, etc., with a total renovation area of ​​20 million square meters. Through the renovation, the heating costs have been saved for customers, which has been well received by customers.

Shandong Urban Construction Vocational College covers an area of ​​1,163 acres. The school's heating area is about 370,000 square meters, and the heat source is a coal-fired boiler with an annual operating cost of about 5 million yuan. The transformation content is a time-sharing and zoned heating energy-saving system, an unmanned heat exchange station control system, a heat network dispatching system, and a pipe network balance system. The heating cost saving rate is more than 40%, which is equivalent to saving 3,334 tons of standard coal.

Since 2017, 69 heat exchange stations and 110 units have been renovated, with a heating area of ​​4.2 million square meters. Based on the on-site survey, a renovation plan was formulated according to the actual situation on site. The renovation content includes smart heating platform, unmanned heat exchange station control system, video monitoring system, climate compensation control system, balance of each branch of the secondary network water collector and balance of the secondary network unit end of some communities. 2020-2021 2021-2022 Energy saving Energy saving rate Heating heat consumption 1336830GJ 1152268GJ 184562GJ 19% Heating area 4 million square meters 4.2 million square meters Unit energy consumption 0.34GJ/㎡ 0.27GJ/㎡
