摘要: 随着能源环境形势的日趋紧张,可再生能源等新型能源的利用愈发重要,太阳能以其丰富、清洁的特点应用最为广泛。本文将太阳能与传统的热泵系统相结合,探究太阳能热泵热水器在低温下的性能。研究表明,太阳能热泵系统可以改善并扩大纯热泵系统的低温适用范围,并且太阳辐照越强,系统性能越好;低温化霜方式宜采用自然化霜,以避免强制化霜能耗高、容易液击、降低系统性能的缺点。

Abstract: With the increasingly tense situation of energy and environment, the use of new energy sources such as renewable energy is becoming more and more important. Solar energy is most widely used for its rich and clean features. This paper combines solar energy with a traditional heat pump system to explore the performance of solar heat pump water heaters at low temperatures. Research shows that the solar heat pump system can improve and expand the low temperature application range of the pure heat pump system, and the stronger the solar radiation, the better the system performance; the low temperature defrosting method should adopt naturalized frost to avoid the high energy consumption and easy of the forced defrosting the disadvantage of liquid hammer and reduced system performance.
