The Control Of The Testing Room Atmosphere
- The THERMOSTATS and HYGROMETER CONTROL VALVES operates by compressed air.
- The air input to the conditioning plant may come from outside or be recirculated air, or a mixture of both.
- In all instance it is filtered before heating and conditioning.
- A fan blows the conditioned air in to the laboratory through special ducts with lowered outlets in the ceiling.
- All the windows are double glazed used to prevent unwanted air coming in from the corridor when people pass in and out of the laboratory.
- Automatic two "towers" are used, one for adding moisture and one for subtracting moisture from the air.
