摘    要:针对冷库运行过程中停机阶段、风机运行阶段、制冷机运行阶段的各点温度变化,采用热镀锡膜铜-康铜热电偶分别测量了3个阶段的库温、果品温度、冷风机进风口和出风口温度及冷风机蒸发器的温度,并对测点的温度场进行了分析.结果表明:果品温度在3个阶段基本恒定在1.8℃;在风机运行阶段蒸发器仍然是冷源;在制冷机运行阶段,蒸发器进出口温差增大,蒸发器温度下降,说明制冷效果良好.

关 键 词:冷库  温度场  铜-康铜热电偶

Abstract:In order to study every changing temperature point of stop stage and fan operation stage and chiller operation stage,the hot tin copper-constantan thermocouple was used to measure respectively the storage temperature,fruit product temperature,air cooler inlet and outlet temperature,cooling fan evaporator’s temperature.These data were analyzed and the results showed that:fruit product temperature was almost constant at 1.8 ℃ at three phases.In fan operation stage,evaporator was still cold source.In chiller operation stage,the temperature difference of evaporator import and export increased,and the evaporator temperature dropped,which indicates good cooling effect.
Keywords:cold storage  temperature field  copper-constantan thermocouple
