摘要
空气源热泵冬季运行除霜时,存在室内环境热舒适性恶化、机组除霜可靠性差和运行不稳定等问题。相变蓄能除霜技术是目前可行的节能新技术。本文对目前常用的几种空气源热泵除霜方式进行对比,并通过计算分析比较了各种除霜方式的热经济性,结果表明蓄能除霜技术具有明显的优越性。
Some problems occur when the air source heat pump is defrosting, such as indoor thermal comfort environment decreasing, deterioration reliability of defrosting, and unstable operation. Phase Change Material (PCM) energy storage has been adopted as a novel energy conservation method. In this paper, some common defrosting methods of the air source heat pump have been compared and also the thermal economy analysis of each defrosting method has been conducted. It shows that the PCM energy storage for defrosting is obviously superior.
