Characteristics of PE ground source heat pump

Ground source heat pump is a new heating and cooling method in China in recent years. Earlier, it has accumulated mature experience in developed countries such as the United States. It is a low-grade heat source that uses shallow water sources on the earth's surface (groundwater, seawater, river water, lake water, etc.) or underground soil heat sources. Through heat pumps and refrigeration cycles, it can produce cooling capacity for summer air conditioning and heat for winter heating . Ground source heat pump heating is more economical than conventional electric heating or oil and gas heating, and usually produces the same amount of heat. The power consumption of ground source heat pump is only 1/4 to 1/5 of that of electric heat. Therefore, the ground source heat pump market is broad.

During the "Twelfth Five-Year Plan" period, China is expected to complete the ground-source heat pump heating (cooling) area of about 350 million square meters. By then, the total market size of geothermal energy development and utilization will exceed 70 billion yuan. PE地源热泵 工程在全国各地轰轰烈烈开展 Therefore, it has been strongly recommended by the Ministry of Construction, and PE ground source heat pump projects have been carried out vigorously throughout the country .

PE ground source heat pump pipes are produced with high-quality HDPE raw materials and extruded by plastic extruder at one time. Compared with metal pipes, PE ground source heat pump pipes have the advantages of stable chemical properties, corrosion resistance, easy processing, good heat exchange performance, and low cost. They are the most ideal dedicated pipes for ground source heat pump systems. The PE ground source heat pump pipeline group is mainly composed of U-shaped parts. The φ32 pipe is firmly welded to the U-shaped parts by using a φ32 electric melting sleeve to realize a 180 ° turn of the pipeline. It has a small size, a compact structure, simple operation and convenient construction. Features.

PE ground source heat pump pipes have greater tensile strength, higher pressure bearing capacity than ordinary PE water supply pipes, and low mechanical expansion. PE ground source heat pump pipe fittings have excellent environmental stress crack resistance and good creep resistance.

PE ground source heat pump pipes have good toughness and flexibility, strong adaptability to uneven foundation and misalignment, and can withstand harsh environments such as earthquakes and typhoons.

PE ground source heat pump pipe material is added with special additives to make the pipe have more beneficial weather resistance (including UV resistance) and long-term thermal stability than ordinary PE water supply pipes.

PE ground source heat pump pipe has strong corrosion resistance. It is used for transporting corrosive media containing antifreeze and does not need anticorrosive treatment, and has a long service life.

The inner wall of PE ground source heat pump pipe is smooth, the water flow resistance is small, the flow resistance is large, and the construction cost is saved. 6. Good abrasion resistance and abrasion resistance.

The special thermal conductivity of PE ground source heat pump is 0.41w / mk, which has good thermal conductivity. At the same time, the special pipe has good low temperature impact resistance, and can be used safely in the temperature range of -20 ° C-40 ° C, and the construction in winter is not affected.

The PE ground source heat pump pipe is easily and reliably connected by electric fusion (or hot fusion), and the construction and maintenance are simple (the water can be kept during the period).
