摘要

节流装置的调节对恒温恒湿箱系统性能具有重要影响。基于恒温恒湿箱定频制冷系统，实验研究了不同目标工况下电子膨胀阀（EEV）开度（10%~30%）对蒸发器过热度、压缩机排气温度、蒸发器翅片温度及箱内温湿度的影响。结果表明：EEV开度为15%~30%时，可保证过热度（8~15 ℃）和排气温度在安全合理范围内；EEV开度为20%以下时，设置旁通毛细管，使压缩机吸气带液冷却而安全运行；低温低湿和高温高湿工况下，较大开度使温湿度调节时间缩短10~20 min，低温高湿和高温低湿工况下，较大开度造成额外湿补偿或热补偿的能耗并延长温湿度调节时间；不同目标工况下，小开度（15%）相比大开度（25%、30%）箱内的相对湿度和干球温度更趋近目标温湿度，温湿度控制精度更高。

Abstract

The regulation of the throttling device has an important impact on the performance of constant-temperature and humidity cabinets. Based on a constant-frequency refrigeration system

the effects of EEV (electronic expansion valve) opening from 10% to 30% on the evaporator superheat

compressor discharge temperature

evaporator fin temperature

and temperature and humidity in the cabinet under different target conditions were experimentally studied. When the opening of the electronic expansion valve is 15%-30%

the superheat (8-15 ℃) and discharge temperature can be guaranteed in safe and reasonable ranges. When the opening of the electronic expansion valve is below 20%

a bypass capillary tube is set for a safe compressor operation with liquid cooling in suction. Under the conditions of low temperature and humidity and high temperature and humidity

the larger opening reduces the temperature and humidity adjustment time by 10-20 min. Under the conditions of a low temperature and high humidity and a high temperature and low humidity

the larger opening causes energy consumption for additional humidity compensation or thermal compensation and prolongs the temperature and humidity adjustment time. Under different target conditions

the relative humidity and dry bulb temperature in the small opening (15%) cabinet are closer to the target temperature and humidity than those for the large opening (25%

30%)

and the temperature and humidity control accuracy is higher.
