摘要

随着空气源热泵供暖规模的扩大，空气源热泵阵列成为中大型供暖项目主要布置方式，然而在空气源热泵阵列中心极易形成“冷岛效应”和“湿岛效应”，诱发热泵机组频繁结除霜，相反频繁结除霜也会影响空气源热泵阵列“冷湿岛效应”。为探究空气源热泵阵列“冷湿岛效应”与结除霜现象相互影响，本文依托山东省威海市某空气源热泵阵列供暖示范工程，搭建现场测试平台，进行现场实测。典型日下测试结果表明，在“冷湿岛效应”的影响下，阵列中心的机组相较于外侧机组除霜频率增加225 %；频繁除霜导致阵列中心机组的冷岛强度降低了4.3 %，湿岛强度升高了3.9 %，效果并不显著。阵列中心机组相较于外侧机组结除霜过程名义制热量损失系数增加59.3 %，平均制热能力和COP下降分别降了31.6 %和34.0 %，阵列中心机组性能衰减显著。本文揭示并量化了空气源热泵“冷湿岛效应”与机组结除霜过程的相互影响，为空气源热泵规模化应用和高效运行提供理论支撑。

Abstract

With the expansion of air source heat pump (ASHP) heating systems

ASHP arrays have become the main arrangement for medium to large-scale heating projects. However

the "cold island effect" and "wet island effect" are prone to form at the center of ASHP arrays

leading to frequent frosting and defrosting in the heat pump units. Conversely

frequent frosting and defrosting also affect the "cold-wet island effect" in ASHP array. To explore the mutual influences between the "cold and wet island effect" and the phenomena of frosting and defrosting

this study was based on an ASHP array heating demonstration project in Weihai

Shandong Province

and established an field testing platform and carried out field measurements. Typical day testing results indicated that

under the influence of the "cold-wet island effect

" the defrosting frequency of units at the center of the array increased by 225 % compared to those on the periphery. Frequent defrosting reduced the cold island effect intensity of the central units by 4.3 %

and increased the wet island effect intensity by 3.9 %

although the effect was not significant. Additionally

the nominal heating capacity loss coefficient during the frosting-defrosting cycle for the central units increased by 59.3 %

and their average heating capacity and COP decreased by 31.6 % and 34.0 %

compared to the peripheral units

indicating significant performance degradation in the central units. This study revealed and quantified the mutual influence between the "cold and wet island effect" and the frosting and defrosting processes in ASHP units

which provided theoretical support for the large-scale application and efficient operation of ASHPs.
