Description

Technical Field

[0001] The invention relates to the technical field of capillary tube mat installation, and in particular to an efficient installation process of a capillary tube mat based on a ground source heat pump system. Background Art

[0002] With the intensification of the global energy crisis and the enhancement of environmental protection awareness, the ground source heat pump system has been used more and more widely as an efficient, energy-saving and environmentally friendly heating and cooling technology. The ground source heat pump system achieves heating and cooling of buildings by utilizing shallow underground geothermal resources, with significant energy-saving effects and low operating costs. However, the efficient operation of the ground source heat pump system depends to a large extent on the installation quality of the capillary mat. As a key component of the ground source heat pump system, the quality of the installation process of the capillary mat directly affects the overall performance and service life of the system.

[0003] The traditional capillary mat installation method has many shortcomings, such as uneven laying, unreliable sealing at the joints, and inadequate waterproofing. These problems not only affect the operating efficiency of the ground source heat pump system, but may also lead to frequent system failures, increase maintenance costs and user inconvenience. Therefore, it is particularly important to develop an efficient and reliable capillary mat installation process.

[0004] At present, there are some patented technologies for capillary mat installation on the market, but these technologies often focus on improving materials or optimizing a single installation step, and lack systematic consideration of the entire installation process. For example, some patented technologies focus on improving the thermal conductivity of capillary mats by adopting new materials or structural designs, but do not involve the actual operational details of the installation process; other patented technologies may focus on specific installation tools or equipment, but fail to provide a comprehensive installation process, making it difficult to ensure the consistency and reliability of installation quality in actual applications. Summary of the invention

[0005] The present invention proposes an efficient installation process for capillary mats based on a ground source heat pump system, which can significantly improve the energy efficiency ratio of the ground source heat pump system, reduce operating costs, extend the service life of the system, and bring users a more comfortable and economical heating and cooling experience.

[0006] The technical solution adopted by the present invention is: an efficient installation process of a capillary mat based on a ground source heat pump system, comprising the following steps: Step 1, preparation: Conduct a survey of the ground source heat pump system at the installation site to determine the laying area and size of the capillary mat; Step 2: Top surface preparation: clean the top surface of the paving area, ensure that the top surface is flat and free of debris, and perform waterproofing; Step 3: Laying the capillary mat: Lay the capillary mat flat on the processed top surface according to the design drawing, and ensure the flatness and no damage of the capillary mat; Step 4: Pipe connection: Connect the inlet and outlet pipes of the capillary mat to the corresponding pipes of the ground source heat pump system, and ensure that the joints are sealed reliably; Step 5: Fixing and protection: Lay a protective layer on the capillary mat to prevent damage to the capillary mat during construction and ensure that it is tightly bonded to the top surface; Step 6, system test: After the capillary mat is laid and connected, perform a system test to ensure there is no water or air leakage, and check the system's operating efficiency; Step 7: Paint protection: After confirming that the system is operating normally, use moisture-proof and crack-resistant paint plaster to paint the capillary mat for protection, and ensure the density and firmness of the paint.

[0007] As a further improvement of the present invention, the capillary mat is composed of a polyethylene matrix, a metal reinforcement layer and a thermal conductive medium layer. The metal reinforcement layer is located outside the polyethylene matrix, and the thermal conductive medium layer uniformly covers the outer surface of the metal reinforcement layer to improve the thermal conductivity of the capillary mat.

[0008] As a further improvement of the present invention, the metal reinforcement layer is made of copper foil to ensure that it has good thermal conductivity and mechanical strength; the thermal conductive medium layer is made of graphene material to further improve the thermal conductivity efficiency of the capillary mat.

[0009] As a further improvement of the present invention, in step one, when conducting the survey of the ground source heat pump system, it is also necessary to measure the thermal physical parameters of the soil, including the thermal conductivity, specific heat capacity and density of the soil, so as to facilitate the subsequent design and calculation of the spacing and length of the capillaries to ensure the efficient operation of the ground source heat pump system.

[0010] As a further improvement of the present invention, in step 2, when performing waterproof and moisture-proof treatment, a double-layer waterproof material is used, first spraying a layer of polyurethane waterproof coating, and then covering it with waterproof and moisture-proof coating to ensure the durability and reliability of the waterproof effect.

[0011] As a further improvement of the present invention, in step three, when laying the capillary, a fixing clamp is used to ensure that there is no gap between the capillary mat and the ground, while avoiding deformation and damage to the capillary mat caused by other construction processes. The spacing of the fixing clamps is arranged according to the specifications and design requirements of the capillary mat, and the spacing does not exceed 30 cm.

[0012] As a further improvement of the present invention, in step four, when connecting the inlet and outlet pipes of the capillary mat, pipe joints and sealing rings are used to ensure the sealing and durability of the connection; at the same time, during the connection process, a torque wrench is used to accurately control the torque of the pipe joint to prevent poor sealing and pipeline damage caused by over-tightening or over-loosening.

[0013] As a further improvement of the present invention, in step five, when laying the protective layer, a material with high compressive strength and good flexibility is selected to provide sufficient protection to prevent mechanical damage to the capillary mat during subsequent construction. At the same time, the laying of the protective layer should ensure that there are no gaps and it can withstand the stress after water passes through the capillary mat.

[0014] As a further improvement of the present invention, in step six, the system test should include a water pressure test and an air pressure test on the capillary mat. The pressure of the water pressure test should not be less than 1.5 times the normal operating pressure of the system and the duration should be no less than 30 minutes; the pressure of the air pressure test should not be less than 1.2 times the normal operating pressure of the system and the duration should be no less than 1 hour.

[0015] As a further improvement of the present invention, in step seven, when plastering the gypsum surface, it is done in layers to ensure that the plaster evenly covers the capillary mat to avoid voids and unevenness.

[0016] The beneficial effects of the present invention are as follows: (1) The present invention significantly improves the energy efficiency ratio of the ground source heat pump system, reduces the operating cost, prolongs the service life of the system, and brings users a more comfortable and economical heating and cooling experience; (2) The present invention ensures the installation quality of the capillary mat through a systematic installation process, thereby ensuring the overall performance and reliability of the ground source heat pump system; (3) The present invention adopts advanced materials and structural design, uses a polyethylene matrix, and combines a metal reinforcement layer and a heat-conducting medium layer to further improve the thermal conductivity of the capillary mat, thereby improving the operating efficiency of the system; (4) The present invention ensures the sealing and durability of the connection and reduces the occurrence of system failures through precise control of construction details, such as the use of special fixing fixtures, special pipe joints and sealing rings, and torque wrenches; (5) The present invention ensures the protection of the capillary mat and the normal operation of the system through waterproof and moisture-proof plaster covering and strict system testing, thereby avoiding system failure and increased maintenance costs caused by improper construction.
