摘 要: 针对空气源热泵供暖系统在低温环境下机组难以启动、室内供暖效果差且能量损失大等问题,将相变蓄能装置引入到热泵系统中,提出了空气源复叠式热泵系统。介绍了该系统的工作原理,分析了低温环境下系统的工作特性,结果表明,利用双级耦合热泵技术提高了机组的制热性能,从根本上解决了能量来源不足的问题。 Aiming at the initiating difficulties, poor indoor heating effect and high energy loss of an air-source heat pump heating system in low temperature conditions, presents the cascade air-source heat pump system by introducing the phase change thermal storage equipment. Expounds the operating principle and analyses the operating characteristics in low temperature conditions. As a result, the heating performance is improved by the double stage coupling heat pump technology, and the energy shortage is overcome.
