摘要

通过对采用吸气喷液的热泵热水器循环过程进行理论分析

建立了压缩机吸气温度、排气温度、机组制热量、功耗及能效比等性能参数与吸气喷液量的关系

研究了不同喷液量对机组性能参数的影响.试验分析了不同运行工况下

吸气喷液引起的热泵热水器性能参数变化趋势

并与计算结果进行了对比分析.研究表明:采用吸气喷液对降低压缩机排气温度具有比较明显的效果

但同时也降低了机组制热量和能效比

提高了功耗; 喷液量比例应该控制在5%以下; 吸气喷液对于热泵热水器在低环境温度下运行具有较好的综合效果; 在环境温度低于20 ℃运行时

采用吸气喷液可以降低压缩机排气温度10 ℃以上

机组制热量下降幅度小于5%

功耗上升幅度小于1.5%

能效比降低幅度低于7%.

Abstract

Based on the theoretical analysis on the working process of an air-source heat pump water heater with liquid injection in suction vapor

the relations between liquid injection ratio and heat pump performance parameters were established. An experiment was conducted under different conditions to investigate the influence of liquid injection on the performance of heat pump water heater. The predictions were verified with the experimental data. The results show that liquid injection could reduce the compressor discharge temperature

but it also reduced the heat capacity and heat coefficient and increase power input of the heat pump water heater. The highest injection ratio should be controlled below 5%. In addition

when the ambient temperature was below 20 ℃

liquid injection could reduce the compressor discharge temperature by above 10 ℃

while the decrease of the heat capacity

the increase of the power input and the decrease of the heat coefficient was less than 5%

1.5%

and 7%

respectively.
