Shandong issued ground-source heat pump construction application technology notice

The Housing and Urban-Rural Development Bureau of Shandong Province recently issued the "Notice on Launching the Technology Demonstration Work of the Ground Source Heat Pump System Building Application Project" and decided to carry out the preliminary technical demonstration work of the ground source heat pump system building application project within the scope of Shandong Province.

"Notice" requirements: The application of ground source heat pump system construction projects must be conducted before the design of the thermal properties of the building design, preparation of a feasibility study report, put an end to blindly launched; second is to prepare a special design of ground source heat pump system, prominently The importance of the source heat pump system design; the third is to organize an expert demonstration meeting to demonstrate the specific design of the ground source heat pump system and provide guidance on existing problems. After the construction unit has adjusted according to the opinions, the technical demonstration will be conducted again. Thoroughly solve the problems caused by unreasonable design.

The "Notice" also stipulates that construction applications for ground-source heat pump systems that have not been technically verified or have not passed the technical justification will not start construction. It is understood that with the gradual implementation of the "notice", Shandong Province will solve the problems of the ground source heat pump system construction application project at the source, promote the comprehensive promotion and application of ground source heat pump technology, and promote the health of renewable energy building application business. development of.

Because ground source heat pump technology has not been used in China for a long time, there is a shortage of professionals, and the technical specifications are not perfect. There is a certain degree of problems in the comprehensive promotion and application of ground source heat pump technology: First, the geothermal basic research work in shallow geothermal energy is lagging behind. Second, the lack of integration of geological exploration, heat pump systems, automatic control, and HVAC systems; third, the design institutions and designers have insufficient understanding of ground source heat pump technology, and the integrated design of building applications is not in place; There are few talents and institutions for research and development of geothermal energy, and they mainly rely on heat pump manufacturers as their promotion force. Fifth, there is a lack of effective supervision on the approval, design, construction, and acceptance of ground source heat pump projects.

The existence of these problems directly affects the design level and engineering quality of the ground-source heat pump system building application project, affects the sustainable and effective use of shallow geothermal energy, and affects the overall promotion of construction applications of ground-source heat pump systems.
