AIR / ENGINEERING
Air Conditioning Planning, Airflow Planning, and Differential Pressure Planning
The operational quality of CPC based on ISO 14644-1 and the 15th Edition of the Japanese Pharmacopoeia is guaranteed by maintaining compliance with cleanliness classifications and the stability of the air-conditioned environment.
We provide consistent facility design, air conditioning design, and construction management based on compliance with particle count specifications for Grades A to D and the influence pathways of air conditioning control factors.
● Airflow planning and filters
Grade transition with a single step difference
We design the area layout so that the transition between different grades occurs one step at a time, with Grade C adjacent to Grade B.
エアロック室の介在
Since instantaneous room pressure fluctuations caused by door opening and closing cannot be controlled by sensors, airlock rooms are installed between different grades to maintain differential pressure.
Control of Differential Pressure Fluctuations
We suppress fluctuations in inter-room differential pressure by considering human factors such as exhaust fan start/stop and door opening/closing, as well as natural factors such as external wind pressure.
Negative Pressure Operation and Containment
When handling infectious specimens, the cell preparation room is set to sub-atmospheric pressure, and air leakage is contained using an airlock room.
Wide and Low-Speed Air Outlets
Increase the outlet area, suppress the outlet air velocity, and do not induce indoor air at the outlet.
Positioning for Air Circulation
Select a shape for the air outlet that facilitates air diffusion and arrange it so that the supplied air reaches the entire room.
Place the suction port near the dust source
The suction port (exhaust port) should be installed near the source to quickly exhaust dust generated in the room
