摘　　要：目的 探讨多家品牌采用不同送风的血液冷藏库温度波动值、温度均匀性、温度偏差、温度不均匀系数和温度变化情况,并评价冷藏库库内温度场的稳定性。方法 选取国内8家采供血机构的血液冷藏库,分别由3家公司(分别简称为TJBY、SQGS、AKGS)提供,并分别有6、1、1家采供血机构采用TJBY品牌冷藏库(分别标识为TJBY1、TJBY2、TJBY3、TJBY4、TJBY5、TJBY6)、SQGS品牌冷藏库(标识为SQGS)、AKGS品牌冷藏库(标识为AKGS)。在冷藏库左侧、中间、右侧各储存单元的上层、中间、下层的几何中心设9个温度采集点,收集6个运行周期的温度,并对库内温度波动值、温度均匀性、温度偏差、温度不均匀系数、平均温度等指标进行分析。结果 TJBY2、TJBY6、SQGS、AKGS的温度不均匀系数较低,两两比较,差异无统计学意义(P>0.05),同时TJBY2、TJBY6冷藏库温度场的稳定性优于TJBY1、TJBY3、TJBY4、TJBY5;除TJBY1、TJBY4、AKGS的平均温度偏离较大外,其他5个品牌标识冷藏库均能保持在设定温度范围的中值(4℃)附近,TJBY1、TJBY4、TJBY5最高温度超过上限(6℃),TJBY3、AKGS最低温度超过下限(2℃);TJBY2、TJBY6、SQGS、AKGS之间的温度波动值均在0.5℃左右,且两两比较,差异均无统计学意义(P>0.05),同时均显著低于TJBY1、TJBY3、TJBY4、TJBY5(P<0.05);TJBY1、TJBY3、TJBY4、TJBY5的温度均匀性>1.0℃,且两两比较,差异无统计学意义(P>0.05),同时均显著高于TJBY2、TJBY6、SQGS、AKGS(P<0.05);TJBY4、TJBY5、AKGS的均温度偏差>1.0℃,仅有TJBY6的温度偏差<0.5℃。结论 采用间歇直吹送风或连续直吹送风的5个品牌标识冷藏库(TJBY1、TJBY3、TJBY4、TJBY5、AKGS)温度场稳定性较差,采用断续直吹送风或高频启动的间歇直吹送风2个品牌标识冷藏库(SQGS和TJBY2)温度场稳定性好。采用微孔送风的TJBY6对温度场稳定性保持更好。冷藏库温度场的稳定性与送风技术相关,微孔送风对血Objective To explore the temperature fluctuation value,temperature uniformity,temperature deviation,temperature nonuniformity coefficient and temperature variation of several brands blood cold storage with different air supply technology,and to evaluate the stability of the temperature field in the reservoir.Methods The blood refrigeration warehouses of 8 domestic blood collection and supply institutions were selected and provided by 3 companies(referred to as TJBY,SQGS and AKGS,respectively).In addition,6,1 and 1 blood collection and supply institutions adopted TJBY brand cold storage(labeled as TJBY1,TJBY2,TJBY3,TJBY4,TJBY5,TJBY6),SQGS brand cold storage(labeled as SQGS)and AKGS brand cold storage(labeled as AKGS),respectively.A total of 9 temperature collection points were set in the geometric center of the upper,middle and lower layers of each storage unit on the left,middle and right sides of the cold storage to collect the temperature of 6 operating cycles,and analyzed the temperature fluctuation value,temperature uniformity,temperature deviation,temperature non-uniformity coefficient,average temperature and other indicators in the storage.Results The temperature non-uniformity coefficients of TJBY2,TJBY6,SQGS and AKGS were lower,and there was no statistically significant difference in pairwise comparison(P>0.05).Meanwhile,the temperature field stability of TJBY2 and TJBY6 cold storage was better than that of TJBY1,TJBY3,TJBY4 and TJBY5.Except for TJBY1,TJBY4,and AKGS,where the average temperature deviation was relatively large,the other five branded refrigerated warehouses could all be maintained near the median of the set temperature range(4℃),the highest temperature of TJBY1,TJBY4 and TJBY5 exceeded the upper limit(6℃),and the lowest temperature of TJBY3 and AKGS exceeded the lower limit(2℃).The temperature fluctuation values of TJBY2,TJBY6,SQGS and AKGS were all around 0.5℃,and there was no statistically significant difference in pairwise comparison(P>0.05),meanwhile,they were significantly lowe
