Design And Optimization Pile Pipe Ground Source Heat Pump System Project

Pile base pipe ground source heat pump system is a new kind of buried pipe arrangement, the biggest advantage in So a new kind of "green energy","renewable energy" system compared with traditional air conditioning system. Project drilling buried ground source heat pump system, heat exchange also increased significantly. Pile type ground source heat pump has a small footprint, non-polluting, high operating efficiency. Used in the earlier works compared to water heat pump and the drilling heat pump system, the heat exchanger directly binding reinforcement cage sets of pile foundation laying, so do the benefits or reduce the land area. Especially into the21st century, the real estate business is booming, commercial buildings, civil construction surge in the number of land price climbing to improve the utilization of the land will be able to direct reduction projects initial investment.Project design pile base source heat pump system, the need to know the temperature of the inlet of the heat exchanger, the water flow rate, the summer heat release and the winter to take the heat parameters and local soil thermophysical parameters, in order to more accurately and efficiently design ground source heat pump system.The subject of a ground source heat pump in Nanjing pile pipe system engineering design, in the design of pre-experimental wells thermal response tests, draw useful data for the design and engineering of the reference data. Ground source heat pump system design involved in the design of a building in Nanjing, writing a book of air conditioning system design, double U-tube ground layout of ground source heat pump, ground source heat pump source effective configuration of the ground source heat pump and cooling and heating load calculation. Design in a timely manner and for the problems found by the double U-the pile pipe system in the pre-construction and construction improvements and adjustments. Engineering design and construction problems and solutions, experience in similar projects. The main content of the subject of two parts:First, the design of pre-experimental wells thermal response test, specific test average initial soil temperature, the certain power heated soil temperature, soil thermal parameters of summer units Yanmi heat release winter linear meter units take heat, heat exchanger Yanmi resistance; design project ground source heat pump system.
