地面耦合热泵（GCHP）系统的传统地下换热器设计方法最初用于住宅建筑。GCHP设计方法是专门为商业建筑开发的。该方法考虑了更大建筑中由于更高的内部负荷、通风空气要求、不同的占用时间表、负荷多样性、邻近垂直热交换器之间的热干扰以及长期地温变化而产生的要求。 建议的程序从建筑物中的区域负荷开始，并近似计算制冷和供暖的年等效满载小时数。已经开发了一个计算机代码来执行与建筑和地下热交换器总数相加有关的许多计算。设计师可以指定热泵制造商和所需的地面回路运行条件。该项目选择每个区域所需的热泵机组，并为每个区域和整个建筑提供效率和电力需求。 一旦提供了有关局部地面热特性的信息，就可以计算出所需的地面热交换器长度。最后，在一栋七区建筑上进行示例设计。调整了几个设计参数，以证明改变最大（和最小）允许回路温度的效果。U形管换热器直径、垂直孔分离距离、热泵机组的效率和设备的运行时间。关键词:1995年，设计，商业，建筑，土壤，热泵，土壤热交换器，热交换器，分区，冷负荷，热负荷，办公室，计算，计算机程序，负荷，热性能计算: 研讨会，ASHRAE Trans。1995年，第101卷，第2部分

Traditional design methods for ground heat exchangers for ground-coupled heat pump (GCHP) systems were originally intended for residential buildings. A GCHP design method has been developed specifically for commercial buildings. The method considers the requirements in larger buildings resulting from higher internal loads, ventilation air requirements, varying occupancy schedules, load diversity, thermal interference between adjacent vertical heat exchangers in close proximity, and long-term ground temperature changes. The recommended procedure begins with the zone loads in the building and an approximation of annual equivalent full-load hours in cooling and heating. A computer code has been developed to perform the many computations involved with summing building and ground heat exchanger totals. The designer is able to specify a heat pump manufacturer and desired ground loop operating conditions. The program selects the heat pump unit required for each zone and provides efficiencies and electrical demand for each zone and for the building total. Once information concerning local ground thermal properties is provided, the required length of ground heat exchanger is calculated. Concludes by performing an example design on a seven-zone building. Several design parameters are adjusted to demonstrate the effect of changing maximum (and minimum) allowable loop temperature. U-bend heat exchanger diameter, vertical bore separation distance, the efficiency of the heat pump units, and operating hours of the equipment.KEYWORDS: year 1995, designing, commercial, buildings, soil, heat pumps, soil heat exchangers, heat exchangers, zones, cooling load, heat load, offices, calculating, computer programs, load, thermal properties
