摘要

本文研究了一种新型无霜空气源热泵热水器系统，该系统在传统系统基础上增加了除湿换热器和蓄热装置，其运行方式包括制热模式和再生模式两种。针对此新型系统，本文搭建了实验台，并通过研究发现，该系统在室外温度为﹣3 ℃、0 ℃和3 ℃、RH(相对湿度)为85%的工况下可以保持无霜运行时间分别为32 min、34 min和36 min；且在再生模式下能够满足干燥剂的再生，保证系统了的持续供热。此外，与逆循环除霜系统相比，在﹣3 ℃和3 ℃，RH为85%下，COP分别高17.9%和3.4%，表明在低温环境下，该系统有相对明显的优势。

Abstract

A novel frost-free air-source heat pump water heater applying dehumidification device and thermal storage on the basis of traditional system is studied in this paper. The operation mode of this system includes heating mode and regeneration mode. An experimental apparatus is built up to study this system

and according to the experiment

the frost-free operating time of this system is 32 min

34 min and 36min respectively when the temperature of air is ﹣3 ℃

0 ℃

3 ℃ and the relative humidity is 85%. And the temperature is high enough for the regeneration of desiccant

which could keep the heat pump heating water continuously. Besides

the COP of this system at temperature of ﹣3 ℃ and 3 ℃ is 17.9% and 3.4% higher than the reverse cycle defrosting system in the same conditions

which proves that this new system has better performance under low environment temperature.
