1.恒温箱、恒湿箱所要求的性能 作为环境试验用的恒温箱、恒湿箱所要求的性能,有以下几点: (1)箱内各部位的温度分布、湿度分布应均匀,即无因位置变化造成的差异。 (2)温湿度不得因温湿度控制或外部干扰出现时间性的波动。 (3)不论试样是散热或吸热,箱内的温度、湿度必须稳定。 (4)在将试样放入试验箱中时,应具备充分的加热、冷却和供湿能力,以便尽快地达到规定的温湿度。 (5)对于用程序控制的升温、降温等,必须完全遵循所编制的程序,热惯性要小。 (6)试验箱的结构必须具备下列特点:不应由于直接的热辐射、热传递而使试样升温或冷却。而且根据试验的要求,若指定箱内的
1. The performance required by the incubator and the humidity chamber As the performance requirements of the incubator and the humid chamber under the environmental test, there are the following points: (1) The temperature distribution and the humidity distribution of the various parts of the chamber should be uniform, that is, No difference due to changes in location. (2) temperature and humidity may not be due to temperature and humidity control or external disturbances appear time-varying. (3) Whether the sample is heat sink or endothermic, the temperature and humidity inside the box must be stable. (4) The sample shall be placed in a test chamber with sufficient heating, cooling and wetting capabilities to achieve the specified temperature and humidity as soon as possible. (5) For the program-controlled heating, cooling, etc., must be fully followed the preparation of the program, thermal inertia to be small. (6) The structure of the test chamber must have the following characteristics: The sample should not be heated or cooled due to direct heat radiation or heat transfer. And according to the test requirements, if the specified box
