HDPE is the most common type of piping material used for ground heat exchangers with decades of proven service for this application. It is recognized in virtually all codes and standards as an approved material for ground heat exchange piping systems.

This type of system uses the HDPE pipe to bring fresh water to the heat pump, and then discharges the water back into the water supply. Only fresh water is used, and there is no need for a special heat transfer or antifreeze solution.

The BlueDuct is the only proven, direct-burial underground duct system made from ultra-durable, advanced HDPE (high-density polyethylene). The products are engineered to protect against corrosion, mold and mildew, radon, rust, and air leaks.

2008年6月5日 · I've been (slowly) talking with the local HVAC pro's about getting the duct work done for my house. I've brought up HDPE/"rigid plastic" and none seem terribly familiar with it. Are HDPE ducts used in homes? Is there some brand name (s) I should use when asking questions about it which they may know? Added: The ductwork would be used for cooling.

高密度聚乙烯（HDPE），為白色粉末或顆粒狀產品。 無毒，無味，結晶度為80%～90%，軟化點為125～135℃，使用温度可達100℃；硬度、拉伸強度和蠕變性優於低密度聚乙烯；耐磨性、電絕緣性、韌性及耐寒性較好；化學穩定性好，在室温條件下，不溶於任何有機溶劑，耐酸、鹼和各種鹽類的腐蝕；薄膜對水蒸氣和空氣的滲透性小，吸水性低；耐老化性能差，耐環境應力開裂性不如低密度聚乙烯，特別是熱氧化作用會使其性能下降，所以樹脂中須加入抗氧劑和紫外線吸收劑 …

The carbon-black pigment in our HDPE duct system provides very high UV resistance, making it an ideal material for outdoor odor control. Like every AirTech™ system, our HDPE system’s molded fittings are specifically designed for efficiency – requiring less power (smaller fans/blowers) to move air through the system and eliminating the ...

The performance and use characteristics of polyethylene pipe make it an ideal choice for use in certain HVAC – Heating, Ventilation, and Air Conditioning – applications.
