摘要：人工环境实验室对温度的控制精度低于工艺性环境要求，但冬季若采用分体式空调制热模式控制，实验室温度的波动范国过大，影响采集实验数据的准确性。提出冬季采用空调制冷模式联合电取暖器稳定人工环境实验室内温度的新方法，在背景实验中将新方法和传统空调制热温度控制方法进行对比，结果表明：采用新方法能大幅度提高人工环境实验房间温度的稳定性。为对新方法中空调的设定制冷温度与电取暖器功率匹配问题做进一步研究而进行探究试验，实验结果表明：空调制冷量Q、测试房间热负荷Q:、电取暖器功率Q：和测试房间其他设备功率Q，存在匹配关系，当空调设定温度相同时，Q十Q一Q一Q：值趋小，人工环境实验室内温度波动频率趋稳定，振幅越小。

Abstract: The temperature control precision demand in artificial environment experiment chamber was lower than the demand in technical environment. If the heating mode of split air conditioner was adopted to control temperatures in chamber in winter conditions, the fluctuation scale of the temperatures in the chamber was too large, which affected the accuracy of data recording. A new method was proposed to stabilize temperatures in artificial environment experiment chamber in winter conditions combing cooling mode of the split air conditioner with an electric heater. In the background experiment, the new method and the control method of heating mode of traditional air conditioning were compared and the results showed that the new method could greatly improve the temperatures stability in the artificial environment experiment chamber. A series of additional experiments were implemented to further study the relationship between the temperature setting of air conditioner in cooling mode and the power of heater.The experimental results showed that there was a matching relation among the cooling capacity of air
