摘　　要：针对空气源热泵现有除霜方法存在的不足,提出了一种空气源热泵溶液喷淋除霜系统,采用防冻溶液对空气源热泵室外换热器进行喷淋除霜,并通过喷淋防冻溶液与空气相接触实现稀溶液的再生。通过初步实验研究验证了该系统溶液喷淋除霜的可行性,采用溶液喷淋的除霜方式抑制机组结霜的效果非常明显,制热量持续维持在较高水平,机组的平均COP相比逆循环除霜方式提升明显。Aiming at the shortcomings of the existing defrosting methods for air-source heat pumps, this paper proposed a novel spray solution defrosting system for air-source heat pump, defrosted by spraying antifreeze solution to the outdoor heat exchanger of air-source heat pump, and spraying dilute solution in contact with air to achieve the dilute solution regeneration. In this paper, the feasibility of spray solution defrosting system was verified by preliminary experimental research, the effect of defrosting by spraying solution to suppress the frosting is very obvious, the heating capacity is maintained at a high level, and the average COP compared to the reverse cycle defrost method is obviously improved.
