地热源闭式循环系统
Ground heat source closed cycle system
在土壤中敷设换热器（管），与土壤直接进行热交换。在冬季供给机组热量，在夏季吸收机组排出的热量。垂直环路（如图1所示）的安装为：先在土壤中钻垂直的孔，然后在孔中装入聚乙烯塑料管。水平环路为在地面以下1.5m的土壤中敷设换热器（管）。垂直环路和水平环路均为从土壤中吸取或放出热量。
Lay heat exchangers (pipes) in the soil for direct heat exchange with the soil. Supply heat to the unit in winter and absorb the heat discharged by the unit in summer. The installation of the vertical loop (as shown in Figure 1) involves drilling vertical holes in the soil first, and then inserting polyethylene plastic pipes into the holes. The horizontal loop involves laying heat exchangers (pipes) in soil 1.5m below the ground level. Both vertical and horizontal loops absorb or release heat from the soil.
地表水或湖水循环系统
Surface water or lake water circulation system
利用江河湖海等地表水资源，通过敷州苗木 保定通风管道 丝网立柱模具 尼龙输送带 保定空压机 高碑店养老院设水中的换热装置进行热量交换。通过在建筑物附近的湖水或其他水体中安装闭式换热装置，为建筑物提供或放出热量。换热装置既要美观，而且要排水方便。湖的大小和深度是尤为关键的，需要通过精密计算，以确定湖水能满足建筑物的制冷和制热需求。
Utilize surface water resources such as rivers, lakes, and seas to exchange heat by installing heat exchange devices in the water. Install closed heat exchangers in lakes or other water bodies near buildings to provide or release heat to the building. The heat exchange device should be both aesthetically pleasing and have convenient drainage. The size and depth of the lake are particularly crucial, and precise calculations are needed to determine whether the lake water can meet the cooling and heating needs of the building.
