摘要
单井回灌一个致命的缺陷是“短路”,即回灌水未充分与土壤进行热量交换就又被抽了回去。这样,随着运行过程的进行抽出的井水温度夏天逐渐升高,冬天逐渐降低,导致投资高、运行效率低、运行费用高,而且在严寒时有无法运行的可能。对于这样一个有严重缺陷的系统纳入某建筑设计标准是不妥的。
A fatal shortcoming of single-well flooding back is 'short circuit'. Which is the water flooding back will be taken back without the heat-exchange adequately with soil. Thus, the temperature of water taken out from the well will rise gradually in summer and fall gradually in winter. This will lead to high level investment, low running efficiency and high running cost. Moreover, there will be the threat of not working in chilliness. It is not proper to bringing a system with serious shortcoming into a standard of architecture design.
