It’s planned to install a new HVAC system in a tableting facility. The current ACPH in all areas are

roduction >10 ACPH, Storage > 5 ACPH. What are the normal operating ranges for these areas in a non-sterile plant ISO 8(Grade D)?
计划在压片间安装一个新的空调系统。目前的换气次数是:生产区>10次/小时,中间站>5次/小时。请问这些ISO 8(D级)区域的换气次数通常多少合适?
Starting a new design, theACPH has to be calculated as the highest value of
对于新的设计,换气次数应考虑以下因素:
the thermal load with amaximum allowed temperature difference of supply air to the specified roomtemperature (common value is a maximum of 6-8K)
送风和具体房间热负荷的温度最大允许差异(最大值通常是6-8K)
