摘要

通过对比现有的空气源热泵空调系统的优缺点，提出了一种新型无霜空气源热泵空调系统。该热泵系统最大的新颖之处在于热交换塔实现了“一塔三用”，不仅冬季可以无霜高效运行与再生，夏季蒸发冷却后性能也有所提升。通过搭建该系统实验平台研究了溶液塔入口空气温湿度、空气流量、溶液入口温度、溶液流量、溶液质量分数对除湿性能及空气出口温度与溶液出口温度的影响，结果表明：出口空气与溶液温度随入口空气温湿度、流量、溶液温度、质量分数的升高

溶液流量的下降而升高；溶液塔的除湿效率主要受风量和溶液流量的影响，而入口空气温湿度、入口溶液温度、溶液质量分数影响很小，溶液塔的除湿量随着室外空气湿度的升高、入口溶液温度的降低、空气流量和溶液流量的升高而升高。

Abstract

By comparing the advantages and disadvantages of the existing air source heat pump air conditioning system

a new type of frost-free air source heat pump air conditioning system is proposed. The biggest novelty of this heat pump system is that the heat exchange tower has realized as "one tower in three uses"

which can not only run and regenerate effectively without frost in winter

but also improve the performance after evaporative cooling in summer. Through constructing the heat pump system platform

the effects of ambient temperature

humidity

air volume flow rate

inlet solution temperature

solution volume flow rate and solution concentration on dehumidification performance

outlet air and solution temperature are studied. It is concluded that the outlet air and solution temperature increase with the increase of inlet air temperature

humidity

volume flow rate

solution temperature and the decrease of solution volume flow rate. As inlet air temperature rises from -4℃ to 2.5℃

the air outlet temperature increased by 3.32℃

solution tower export solution temperature increased by 1.62℃. As the rise of the solution tower entrance solution temperature

air outlet temperature increased by 1.9℃

export solution temperature increased by 2.66℃. Dehumidification efficiency is mainly affected by air and solution volume flow rate. The inlet air temperature and humidity

solution temperature and solution concentration affect it little

the dehumidification rate increases with higher outdoor air humidity

air volume flow rate

solution volume flow rate and lower solution temperature.
