Pipeline same-stroke type construction method for ground source heat pump system

Abstract

The invention discloses a pipeline same-stroke type construction method for a ground source heat pump system. The pipeline same-stroke type construction method comprises the steps of heat source well construction, vertical pipe connecting pipe construction, horizontal pipe construction, water pressure testing, backfilling, water collecting well construction, other system construction and system debugging. The pipeline same-stroke type construction method has the beneficial effects that all wells are independently gathered to a water collecting and distributing well, a horizontal connecting pipe is not provided with a connector, the water leakage hidden danger is reduced, the construction efficiency is improved, the construction period is shortened, hydraulic balance adjustment can be better conducted in the debugging stage, the optimal design is achieved, the hydraulic adjustment efficiency is higher than that of a traditional hydraulic adjustment method, opening and closing of the wells can be flexibly adjusted in later-period operation, intermittent operation is achieved, the great effect on heat balance and energy saving of a geo-thermal well is achieved, and the construction quality of a ground source heat pump of the project and the overall stability of the system are greatly improved.

Description

Technical field[0001]The present invention relates to a ground source heat pump system construction, specifically a groundwelnoff system pipeline with a construction work method, which belongs to the technical field of civil construction.Background technique[0002]With the development of the times and the demand for energy conservation and emission reduction, the ternary heat pump system is widely used in civil buildings. Especially the soil heat pump is more selected in the civilian housing by its advantages. However, the traditional gentle heat pump system also has the following disadvantages: 1. Connecting hot wells and horizontal buried tubes are used in partitioned water, and the force balance is difficult to adjust, resulting in unevenness of the heat source well, no design value; 2, ground source heat pump The system is generally partitioned, and the batch well is operated in a dry tube, there are many horizontal pipe joints, leaking hidden dangers. The horizontal tube and a s...

Problems solved by technology

However, the traditional geothermal heat pump system also has the following disadvantages: 1. The horizontal buried pipes connected to the hot wells all use partitioned and different-program water, which makes it difficult to adjust the force balance, resulting in uneven output of the heat source wells, which cannot reach the design value; 2. Ground source heat pumps The system is generally set up in partitions, and batch wells are connected in parallel to run on one main pipe. There are many horizontal pipe joints, and the hidden danger of water leakage is great.

If the horizontal pipe and a single heat exchange well are damaged, the regional well may fail, which will affect the operation of the overall system and cause irreversible losses, which is not conducive to later management and operation

Moreover, intermittent operation cannot be performed between wells, and the operation strategy cannot be adjusted flexibly, which is not conducive to the heat balance adjustment of ground source heat pump wells
