Plum-blossom-shaped phase change geothermal energy pile and use method thereof
The invention provides a plum-blossom-shaped phase change geothermal energy pile and a use method thereof, and belongs to the field of ground source heat pump air conditioning technologies and energystructures. The energy pile is composed of a reinforced concrete pile body and a plum-blossom-shaped phase change geothermal heat exchanger built in the pile body; the reinforced concrete pile body iscomposed of a reinforcement cage and placed concrete; the plum-blossom-shaped phase change geothermal heat exchanger is composed of a phase change inner tube, an outer tube, a bottom joint and a topjoint; the phase change inner tube is composed of an inner sleeve, an outer sleeve and a composite phase change material; and the composite phase change material is encapsulated between the inner sleeve and the outer sleeve. The plum-blossom-shaped phase change geothermal energy pile provided by the invention solves the defects that the temperature of a traditional U-shaped tube energy pile body is large and the displacement of the pile body is obvious; through the heat absorption and heat release of the phase change material in the plum-blossom-shaped phase change geothermal heat exchanger, thermal interference of inlet and outlet pipes can be reduced, the temperature change amplitude of the energy pile body can be reduced, the thermal strain of the energy pile and the displacement of thepile body can be relieved, and at the same time, the output capability of the geothermal heat exchanger is increased, and the heat exchange performance of the geothermal heat exchanger is improved.
一种梅花形相变地热能量桩及其使用方法，属于地源热泵空调技术及能源结构领域，能量桩由钢筋混凝土桩体与内置桩体中的梅花形相变地热换热器构成，钢筋混凝土桩体由钢筋笼与浇灌混凝土组成；梅花形相变地热换热器由相变内管、外管、底部接头及顶部接头组成；相变内管由内套管、外套管及复合相变材料组成；复合相变材料封装于内套管与外套管之间。本发明解决了传统U型管能量桩体温度变化大及桩体位移明显的缺陷，通过梅花形相变地热换热器中相变材料的吸热与放热，可以在消减进出水管热干扰、降低能量桩体温度变化幅度、缓解能量桩热应变及其导致的桩体位移的同时，增大地热换热器的输出能力，提高其换热性能。
