摘要
在太阳辐射动态变化的情况下,对制冷量为5kW的水冷式太阳能吸收式制冷机的性能进行了模拟,得出了集热器出口水温随时间变化的规律曲线以及在此规律的影响下吸收式制冷机的性能曲线。模拟结果表明水冷式太阳能吸收式制冷机在理论上是切实可行的,但是集热器出口水温度的变化以及冷却水温度对系统性能有较大的影响。冷却水温度越低、系统的性能系数越高。
A water-cooled solar-assisted absorption air conditioning system with cooling capacity of 5kW was simulated based on the properties of aqueous lithium bromide.The performance of the system and the variation of the temperature of exit hot water of the flat plate solar collector were analyzed.The simulation showed that water-cooled solar-assisted absorption air conditioning system is feasible in theory and the variation of the cooling water temperature affected obviously the coefficient of performance of the system.The lower temperature of the cooling water is,the higher coefficient of performance of the system will be.
