Lab constant temperature and humidity air conditioner (See Seth laboratory constant temperature and humidity air conditioner)
（1）安全可靠
Safety and reliability
進口高精度溫濕度傳感器能準確測量實驗室內實時的溫濕度數值并傳輸給控制器，直流變頻壓縮機無級調節、無級調節電加熱器、模擬量控制加濕器可根據實際實驗室需求調節輸出功率，使實驗室內溫度濕度處于穩定狀態。含濕量的控制策略，使控制實驗室內濕度控制快速準確，沒有誤操作誤判斷。
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）綠色節能
Green energy-saving
直流變頻壓縮機，可根據實驗室熱負荷輸出制冷量，冷量無級調節，比交流變頻機組節能約20%，比定頻機組節能約50%。運行噪音低，比交流變頻機組噪音低約5~10分貝，系統壓力高，除濕能力強，采用R410A環保冷媒、采用電子膨脹閥，精確控制冷媒流量、電加熱、電加濕、室外風機無級調節。
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
采用通過嚴格認證測試的國際品牌零部件，EMC測試符合歐盟標準，整個系統具備硬件及軟件的多重安全保護：電加熱過熱保護、加濕器缺水保護、壓縮機高低壓、過載保護、風機故障保護、電壓、電流超限保護、溢水、火警等一系列安全保護、設備出廠前均通過嚴格的開機運行測試，直流變頻機組出廠前進行氟利昂保壓。
The internationally known brａnd parts, which have passed strict certification tests, are adopted; EMC test conforms to EU standard. The overall system is equipped with multiple security protection of hardware and software: a series of safety protections like overheating protection for electric heating, excessive low water level protection for humidifier, high-low and overloading protection for compressor, fan fault protection, voltage and current over-limit protection, overflow and fire alarm. The equipment passed the strict operation test before leaving the factory and Freon pressure keeping before DC frequency conversion unit leaves the factory.
