摘要:

空气源热泵热水系统利用空气作为低温热源制取热水, 是可持续发展的技术之一。以系统的COP 值作为指标, 比较额 定制水量、水温和环境温度对实验系统的经济性能的影响。对实验数据分析, 删除无关点, 再利用最小二乘的数学方法, 进行 数值分析可知:空气源热泵热水器系统COP 值会随着额定制水量的升高而增加;随着水温提高而减小;随着环境温度的提高 而增加, 但是影响COP 值变化的幅度并不一样, 水温对空气源热泵热水机组的COP 值的影响较大, 环境温度次之, 而额定制 水量影响最小。

Abstract:

Air sources heat pump water heater is one of sustainable technique w hich uses low temperature air as source to heat water .It takes systemic COP as index to compare rated quantitaty o f making w ate r , temperature of water and ambient temperature to cont ribute to the sy stemic economical performance .In order to analyse experimental date , delete the outlying o nes and use mathematics method .COP of air source heat pump w ater heate r is increased by the increase of rated quantitaty of making water , addi tion of ambient temperature , and decrease o f w ate r temperature .But the v ariance ratio is dif fe rent from each other .Wate r temperature has the biggest ef fect on COP while the rated quantitaty of making w ate r has the least .And ambient temperature′s ef fect is between them .
