Pneumatic components control valve in the design of the beginning, because it can not find matching, so it will create the entire system imbalance, which will cause unnecessary loss of energy consumption, so to the possible system design at the beginning of the necessary perfect.
If the system can not reach full capacity because of system imbalances under design conditions, the total investment in the entire plant will not be rewarded. When the maximum load is required, the pneumatics control valve is fully open and can not handle this condition. Determining the size of the two-way control valve is difficult, the calculated valve is generally not available in the market, so they are usually too large size. So that the balance of the circulatory system becomes very critical, in general this part of the investment is less than one percent of the total investment in HVAC. Every morning, after a night of downtime, all power needs to be mobilized to restore comfort as quickly as possible. A well-balanced system can be done quickly. If the start-up time can save 30 minutes, compared to 8 hours of work time, you can save 6% of energy consumption per day. This is more than all the allocation of pumping costs.
