摘要:

借鉴分层水蓄冷方式,提出利用稳流器装置从水体底部取水、同温层回水的思路,建立了二维竖向水动力水温模型,与实测值的比较表明,该模型可以较准确地反映水体全年自然水温分布状态。利用该水温模型研究了水体的最大供冷能力,分析了供回水温差、气候和水深的影响。

Abstract:

Based on the stratified chilled water storage mode, presents the method that outlet water is delivered from near the deepest level and returns to the level where the temperature of ambient water most closely matches the inlet water temperature using current regulator. Develops a two-dimensional vertical hydrodynamic water temperature model. A comparison result with measured value shows that the model can accurately simulate actual profile of water temperature. Predicts maximum cooling capacity of water pond with the model and analyses the influence of temperature difference of inlet and outlet water, climate and water depth on the maximum cooling capacity.
