Experimental research on thermal comfort of ship cabin air conditioning system
In order to study the thermal comfort of active chilled beam(ACB)in ship cabins,based on a certain ship cabin environment,experimental methods were used to study the thermal comfort of ACB air conditioning in ship cabins un-der different air supply parameters,and compared with traditional fan coil units(FCU)air conditioner for comparison.The experimental results show that when the air supply temperature,air supply volume and air supply angle increase respectively,the indoor thermal comfort first increases and then decreases.The air supply temperature,air volume and air supply angle are 20℃,80 m3/h,and 120°,and the indoor thermal comfort is optimal.At the same time,compared with the baseline working conditions,the supply air temperature can reduce the absolute value of PMV-PPD by 50％and 10％;the air supply volume can reduce the personnel vertical air temperature difference(VATD)by 60％,and the PMV-PPD by 75％and 77.4％.The ab-solute value of PPD improves the air distribution characteristic index(ADPI)by 9.6％;the air supply angle can reduce the personnel VATD by 20％,the absolute value of PMV-PPD by 55.5％and 54.5％respectively,and improve the ADPI by 9.8％.In addition,ACB The indoor thermal environment parameters are more stable than those of FCU,personnel VATD is reduced by 1.5℃,and thermal comfort is higher.
