Shandong Province Issued "Circular on Strengthening Management of Construction Projects of Ground Source Heat Pump System"

Abstract: The Shandong Provincial Department of Housing Urban and Rural Development issued the Notice on Strengthening the Management of Construction Projects for Ground Source Heat Pump Systems (Lu Jian Jie Ke Zi [2011] No. 13), which requires the strengthening of the application and management of ground source heat pump systems. The application effect of the source heat pump system promotes the in-depth and healthy development of the application of renewable energy buildings. In recent years, the construction of ground source heat pump systems in Shandong Province has developed rapidly. Geothermal energy has become a key area for renewable energy building applications and has achieved good energy-saving and emission reduction effects.

The "Notice" proposed that the principles for the construction of ground source heat pump systems in Shandong Province include the following: priority should be given to the development of ground-sourced geothermal heat pump systems, reclaimed water source heat pump systems, and surface water-ground source heat pump systems; and the new construction, reconstruction, and expansion of civil engineering with applicable conditions should be completed. The construction project will give priority to the use of ground-source heat pump systems, and insist on a unified plan, comprehensive utilization, emphasis on efficiency, development and environmental protection.

The "Notice" requires that projects that intend to use ground-source heat pump systems should be evaluated for economic feasibility prior to commencement of construction; equipment rooms and ground-based heat pump systems for ground-source heat pumps should be entrusted by design-qualified units to carry out special designs and must not be carried out without surveying. The design shall not be used for construction; it shall consider the cold heat balance of the ground source heat pump system to ensure long-term heating and cooling effects; the special design and technical plan of the project shall be organized by the experts of the urban and rural housing construction department to conduct technical demonstrations. The public buildings of 30,000 square meters and below and the residential buildings of 100,000 square meters and below are organized and verified by the housing and urban-rural construction departments of the municipal districts and cities. The public buildings of more than 30,000 square meters and the residences of more than 100,000 square meters The construction project is organized by the Provincial Department of Housing and Urban-Rural Development. The investigation, design, construction and supervision of the ground source heat pump system must be conducted through tenders and entrusted with qualified units; the ground (water) source used for all ground source heat pump system building application projects The heat pump unit must be a product certified by Shandong Province for renewable energy building application technology products; Before the heat pump system is put into use, it shall be carried out overall operation and commissioning, and organizations such as design, construction, supervision and equipment supply shall be responsible for the completion acceptance and registration of the project; the operation and management personnel of the ground source heat pump system shall participate in the organization of the Provincial Department of Housing Urban and Rural Development. Professional training, certificate holders.

The "Notice" stipulates that projects that fall into one of the following seven categories of situations will not be approved by the housing and urban-rural development department:

Construction of groundwater ground source heat pump systems in areas with dense buildings such as cities and towns;

Groundwater source heat pump system is constructed in groundwater overdraft area and heavy land subsidence area;

Construction of groundwater source heat pump systems in drinking water source protection areas;

Groundwater source heat pump system can not use the groundwater to recharge all the recharged to the same aquifer, the well spacing can not reach a reasonable impact radius, or recharging may cause waste and pollution of groundwater;

The backwater of an open surface water source heat pump system may have a significant impact on the surface water environment, or the surface water body of a closed freshwater source heat pump system does not meet the project design conditions;

Ground source geothermal heat pump systems may have a significant impact on the groundwater environment;

The groundwater water source heat pump system has not been verified for water resources, and has not been approved for water abstraction and drilling.

Geothermal heat includes deep geothermal energy with relatively high temperature or shallow geothermal energy with low temperature. Waste heat is low-grade heat energy generated and emitted during industrial production or human life. These heat energy must be collected, transported, converted, and upgraded. Can be used. Geothermal utilization is the development and utilization of new energy and renewable energy. Waste heat recovery and utilization is an important technology for energy conservation and emission reduction. Geothermal utilization and waste heat recovery industry have great potential for development. Take Weifang as an example. According to the evaluation result of shallow geothermal energy, the total amount of shallow geothermal energy available in Weifang City is equivalent to approximately 47 million tons of standard coal. The survey data of industrial waste water in Weifang City shows that only some of the enterprises in the central city have relatively high residual heat from industrial wastewater. At 660,000 tons of standard coal.

The "Notice" requires cities, counties (cities, districts) housing urban and rural construction departments to incorporate ground source heat pump system building application projects into the project construction process, strengthen the supervision and inspection of development, design, construction, supervision and supervision, and ensure that they are in construction. Application of ground source heat pump technology for engineering quality and technology.
