Abstract

To investigate the effect of different drying conditions on the efficacy of a closed heat pump clothing-drying system

parametric studies with control variables were carried out on the circulating air volumetric flow rate

expansion valve opening

and air inlet temperature within the drying chamber and their impact on system heat production

heat pump system coefficient of performance (

COP

)

cooling capacity utilization ratio (

)

and exergy loss. The findings indicated that when the expansion valve was set to 70% opening

the circulating air volumetric flow rate was increased from 500 m

/h to 1 000 m

and the heat generation of the system increased by 59.73%. In contrast

the

COP

and exergy loss decreased by 31.29%

56.65%

and 31.31%

spectively. Furthermore

when the circulating air volumetric flow rate of 1 000 m

/h was maintained while adjusting the expansion valve opening from 20% to 70%

the heat generation

COP

and

of the system increased by 32.58%

6.51%

and 29.51%

respectively. At the same time

the exergy loss decreased by 12.44%. Finally

under the conditions of a 70% open expansion valve

a circulating air volumetric flow rate of 1 000 m

and an increase in the desiccator′s air intake temperature from 40 ℃ to 70 ℃

the heat generation of the system increased by 43.71%

while the

COP

and exergy loss decreased by 11.22%

60.84%

and 14.17%

respectively. These results emphasize the advantages of reducing the circulating air volumetric flow rate and inlet air temperature within the drying chamber while increasing the expansion valve opening

as these adjustments help to improve the overall performance of the system and promote energy efficiency.
