摘要

基于对空气源热泵结霜机理的研究

从抑制结霜的两个条件出发

提出了无霜空气源热泵新系统。选取适用于该系统的喷淋溶液

搭建了实验台。通过实验验证

证明此系统具有可行性。"防霜"模式运行时

送风温差比常规系统高1.5℃

供热量高6%

且送风参数稳定

运行过程中

压缩比基本保持不变

压缩机和系统稳定性高。选用甘油水溶液作为喷淋溶液时

为保证防霜效果

甘油质量分数应在31%~65%;单位迎风面积喷淋流量应在0.53~0.64 t·(h·m2)-1。

Abstract

Based on the study of the mechanism of defrosting of air-source heat pump (ASHP)

a novel non-frosting air-source heat pump (NASHP) and its test rig were developed.The NASHP system has been proved feasible by the experiment.When it ran in "frost prevention" mode

its temperature difference of air was 1.5℃ larger and its heat output was 6% higher than that of conventional system.Moreover

for the compression ratio and parameters of air almost kept the same in the running process

the compressor and system was stable.When the glycerol was selected as spray solution for NASHP

for ensuring the effect of frost prevention

glycerol content should be 31%-65%(mass) and its flow of unit windward area should be 0.53-0.64 t·(h·m2)-1.
