摘要
分析了影响太阳能吸收式空调系统集热面积的因素;得出系统集热面积单耗的日逐时值;根据太阳能吸收式空调系统特点,提出了一种确定集热器集热面积的新方法,并以2级吸收式太阳能空调系统为例进行了详细阐述。分析结果表明,为减少集热面积,优化系统,须对太阳能空调系统增设蓄热装置。太阳能吸收式空调运行在8:00～18:00时,系统所需的最小集热面积单耗为1.085 m2/m2,其对应的蓄热器的容积单耗为0.036 3m3/m2,且随着太阳能空调运行时间的缩短,最小集热面积单耗减小,蓄热器容积单耗增加。
The factors that influenced solar collector area of solar air-conditioning system were analyzed and hourly unit consumption of the collector area of solar air-conditioning system was proposed. On the base of characters of solar absorption air-conditioning system, a new method to compute solar collector area was presented, it was explained detailedly with a solar two-stage absorption air-conditioning system as example. The theoretical analysis results showed that the thermal storage device must be equipped for solar air-conditioning system in order to decrease solar collector area and to optimize the system. When the solar air-conditioning system worked from 8 am to 18 pm, the minimal unit consumption of collector area of the system was 1.085 m^2/m^2 and the unit volume consumption of thermal storage device was 0.036 3 m^3/m^2. Along with the shortening of operation time of solar air-condition system, the minimal unit consumption of collector area was decreased and unit volume consumption of thermal storage device was increased.
