随着科学技术的发展,各类精密设备逐渐增多,它大多要求净化、稳定的工作环境,以保证其正常工作的进行。空调机尤其是大型空调设备在改善工作环境中起着决定性的作用。空调机组的构成主要分两大部分。其一为执行主设备,如制冷、制热、产湿和净化等部分,另部分是检测控制设备。我院在接装设计 CT定空调装置时,发现其原有空调控制部分不但保护性能不好,而且控制精度过低,不能满足要求。为此我们在研制“温湿度控制仪”的基
With the development of science and technology, various types of precision equipment are gradually increasing, and most of them require decontamination and stable working environment so as to ensure their normal work progress. Air conditioners, especially large air conditioning units, play a decisive role in improving the working environment. The composition of air conditioning unit is divided into two parts. One is the executive main equipment, such as refrigeration, heating, wet production and purification and other parts, the other part is the detection and control equipment. In our hospital, we decided to design CT air-conditioning installation and found that the control part of the original air-conditioning not only failed to protect, but also the control accuracy was too low to meet the requirements. To this end we are developing “temperature and humidity control instrument” base
