| 摘 要： | 闭式循环太阳能空调系统减少了蓄热水箱以及与之相关的热水循环泵,直接在太阳能集热器与制冷机组之间形成热水循环环路,系统得到简化的同时,降低了水泵功耗,具有明显的经济性和节能性。然而,由于系统水容量较低,闭式循环太阳能空调系统在运行过程中呈现出明显的波动性。通过研究主要过程参数的变化率,对系统运行的热稳定性进行了分析,并对系统的应用方式进行了探讨。

| Abstract: | The hot water was directly circulated between the solar collector array and the chiller in a closed-cycle solar cooling system because the heat storage water tank and the related hot water pump were removed.As a result,the system was more economical and energy-saving because of the simplicity of the system and the reduction of the pump power.However,the closed-cycle solar cooling system presented obvious wave character owing to a lower water capacity.Through the investigation of variation ratio of main proc... |
