- Cost & Energy Saving
The introduction of an airflow system that is capable of changing air flow rates depending on fume hoods' operation rate and human existence allows a drastic reduction in fan energy consumption as well as in heat source energy consumption for heating and cooling of fresh air intaken from outside.
Cost and energy saving by effectual airflow control
This is a high performance, cost and energy saving system, as it controls the airflow rates to the minimum required in accordance with fume hoods' operation rate, i.e. the total open areas of sashes, and also switches fume hoods' face velocity between 0.5m/s and 0.3m/s in response to the signals from human sensors.
| System/Condition | Nos. of fume hoods | Exhaust capacity of fume hoods* | Air supply fan | Exhaust fan | Air supply fan for air-curtain |
| Constant air volume system |
10 | 1,000CMH/hood | 5.5kwh (9,000CMH) x 1 | 5.5kwh (10,000CMH) x 1 | - |
| Air-curtain type system | 10 | 300CMH/hood | 2.2kwh (2,000CMH) x 1 | 5.5kwh (10,000CMH) x 1 | 0.45kwh (700CMH) x 10 |
| Variable air volume system | 10 | 1,000CMH/hood | 5.5kwh (1,000 to 9,000CMH) x 1 | 5.5kwh (2,000 to 10,000CMH) x 1 | - |
