The imported high-precision temperature and humidity sensor can accurately measure the real time temperature and humidity values inside the lab and transmit to controller. Stepless adjustment of DC frequency conversion compressor, stepless adjustment of electric heater and analogue control humidifier can adjust the output power according to lab requirements to make the temperature and humidity inside the lab in a stable condition. The absolute moisture control strategy makes the quick and accurate humidity control inside the lab possible and without misoperation or misjudgment.
（2）绿色节能
Green energy-saving
直流变频压缩机，可根据实验室热负荷输出制冷量，冷量无级调节，比交流变频机组节能约20%，比定频机组节能约50%。运行噪音低，比交流变频机组噪音低约5~10分贝，系统压力高，除湿能力强，采用R410A环保冷媒、采用电子膨胀阀，精确控制冷媒流量、电加热、电加湿、室外风机无级调节。
DC frequency conversion compressor can output refrigerating capacity based on lab heat load. Stepless adjustment of cold saves about 20% energy than AC frequency conversion unit and about 50% energy saving than constant frequency unit. The low running noise is 5-10 decibels lower than AC frequency conversion unit. The system’s high pressure and strong ability to dehumidification adopts the R410A environmental refrigerant and electronic expansion valve to accurately control refrigerant flow, electric heating, electric moistening and stepless adjustment of outdoor fans.
（3）安全可靠
Safety and reliability
