摘要

空气源热泵结霜过程会恶化机组的实际运行性能，重霜工况下尤为严重，发展抑霜型空气源热泵是保障其高效适用和良性发展的关键。本文依托四川省康定市的某住宅示范工程，开展抑霜型空气源热泵和常规型空气源热泵的现场实测研究，研究抑霜型空气源热泵实际应用中的抑霜、制热性能表现，并进行技术经济性分析。结果表明：抑霜型空气源热泵抑霜效果显著，制热性能得到显著改善，能效提升达到21%~37.3%，费用年值比常规空气源热泵降低了13%，1年左右即可回收追加的投资，具有更好的技术经济性，有助于空气源热泵技术在严重结霜气候区域的高效应用。

Abstract

Frosting (especially severe frosting) in air-source heat pump (ASHP) units leads to a substantial decrease in operating performance. The development of frost-suppression ASHPs (FSASHPs) is key to ensuring their efficient application and healthy development. In this study

a field test study was conducted using a residential demonstration project in Kangding City

Sichuan Province. The study compared an FSASHP and a conventional ASHP unit to explore the frosting suppression and operating performances and analyze the economy of the FSASHP unit. The results showed that the effects of frosting suppression and the improvement of heating performances were substantial for the FSASHP unit. The coefficients of performance of the FSASHP unit were 21%–37.3% higher

with annual costs 13% lower compared to those of the conventional ASHP unit. The payback period of the FSASHP unit was approximately 1 year

and the FSASHP unit had better technical and economic efficiency. This study was helpful for the efficient application of ASHP units in severe frosting regions.
