SPF级实验动物设施是一个恒温、恒湿、恒压强梯度的高洁净系统 ,一旦投入运行 ,就必须有一个完备的自动化保证体系确保系统的能源 (电源、热源、冷源 )供应 ,使得系统内的压强梯度、空气洁净度、温度、湿度、光照度时刻保持在国家要求的标准范围内 ,从而保证洁净系统的正常运行 ,避免重大污染事故的发生 SPF laboratory animal facility is a high-clean system with constant temperature, constant humidity and constant pressure gradient. Once put into operation, a complete automatic assurance system must ensure that the system’s energy (power source, heat source and cold source) is supplied, so that the system Within the pressure gradient, air cleanliness, temperature, humidity, illumination at all times to maintain the required standard in the country, so as to ensure the normal operation of clean systems to avoid the occurrence of major pollution accidents
