北方对虾养殖中太阳能加热系统的性能分析

以半地下式塑料大棚凡纳滨对虾(Litopenaeus vannamei)工厂化养殖系统为研究对象,了解太阳能加热系统的性能.通过测量其主要运行参数,进行系统热利用效率的计算和经济性分析.结果表明,该太阳能加热系统集热器的集热效率在4月份可达40%以上,池中散热器热利用效率在50%左右.在4、5月份和11、12月份利用太阳能加热可维持对虾生长所需的水温,延长对虾养殖时间,至少可增加一茬对虾产量.

Performance analysis of the solar energy heat system in shrimp culture in northern region of China

The experiment on the use of solar heating system in Litopenaeus vannamei culture was conducted taking a semi-underground shrimp culture plastic shed in Qingdao by measuring the main operation parameters and calculating the thermal efficiency as well as economic analysis.Results showed that the thermal efficiency of the collector in solar energy heating system in April was over 40%,while the thermal efficiency of radiator in shrimp pond was about 50%.In a conclusion,the water temperature could maintain the growth of shrimp in April,May,November and December for northern region of China by using solar energy,which could prolong the time of shrimp culture.
