## 2. Reduced Blowdown Time

Unstable networks ( systems ) frequently switch between load and idle [no-load]

## Sample Calculation:

Energy losses due to blowdown

- 60 kw Compressor
- Discharge time approximately 1 minute
- 15 load – idle cycle per hour
- Receiver tank volume 2000 l
- 4000 hours in operation per year
- Energy cost RM0.25 per kwh

4000 hours per year X 15 load – idle cycle per hour

60,000 load – idle cycles per year X 1 minute

60,000 minutes blowdown =1000 hours blowdown time

Therefore;

Energy Loss = 1000 hours blowdown time X 45/2 kw [ consumption when idling on blowdown]

22,500 kwh X 25 cents

### RM 5, 625.00 per year
