EFFECTIVE USE COMPARISON BETWEEN VAN BODY BALANCE (STATIC Balancing VALVE) AND BALANCED VALVE AUTOMATION (AUTOMATIC VALVE Balancing) 
A - The pressure drop and the cost of the valve (pressure drop and high cost of valves) 
I - Balancing Valves - pressure drop and cost of valves. 
Use balancing valves, floor, and any required installation of additional valves should be high pressure loss and increase the cost of valves. 
Manual Balancing Valves partner need for riser valves, floor, and branches mà required high pressure drop and high cost of valves. 
 
Balancing Valves 
Automatic balancing valves 

II - automatic balancing valve - low pressure drop and the total cost to buy the valve at 
When installing automatic balancing valves will not need valves Other valves between floors, in the floor, and branches only install automatic valves at the end of the unit so that very low pressure drop and reduced costs the van. 
Automatic Balancing Valves need no partner for riser valves, floor, and branches, only install the automatic balancing valves at the terminal units with the result of low pressure drop and low cost of valves. 
 
B - labor costs 
I - Balancing Valve - Result of poor balancing and high cost labors? 
Balancing Valves to the officials and workers and experienced technicians to adjust or balance hundreds balancing valves in the system on the scale of the indoor unit or AHU FCU. This requires a lot of manpower and very difficult to balance correctly the van. 
Manual Balancing Valves need reliable and skilled technician to adjust or balance WORKMAN hundreds of Manual Balancing Valves in the system theo capacity of Fan Coil or AHU mà Occurs rarely in reality with the result of poor balancing and high cost labors? 
II - automatic balancing valve - More accurate and reliable 
Automatic balancing valves precise and reliable than mechanical valves balance was not adjusted so no cost calibration valve. 
Automatic Balancing Valves are more accurate and reliable without any adjusting or balancing cost. 
 
C - Operating Expenses 
I - Balancing Valves - high operating costs at maximum capacity 
With the complex and difficult adjustment Balancing Valves should often cause traffic overload in a pipeline system which increases energy costs for pumping cooling water. 
With the complex and confused method of adjusting Manual Balancing Valves Thường caused the overflow Electricity in circuits with high chilled water pump at cost. 
II - automatic balancing valve - low operating costs at maximum capacity 
Balancing valves operate at design flow is appropriate therefore energy costs for pumping cooling water will be minimal. 
Automatic Balancing Valves operated with minimum flow at proper kế Electricity cost for chilled water pump. 
 
D - Performance 
I - Balancing Valves - high operating costs when unused capacity cost at partial load operating -High 
As part of the operation system with higher pressure will cause excess traffic in the rest of the system is open. 
When the partial pressure higher load, causing overflow in re-opening Remain circuits. 
II - automatic balancing valve - low operating costs, although not at full capacity operation - Low operating cost at partial load 
If only partially operational capacity will cause pressure on the system is higher. When that balance valve will automatically positioned to suit the design flow has thus electricity costs would operate cooling pumps at a minimum. 
Higher pressure system Occurs while partial load, Automatic Balancing Valves chính nó would re-position to the kế flow with minimum Electricity cost for chilled water pump. 
 
E - Flow in the pipeline 
I - Balancing Valves - Furniture overflow to the circuits might cause underflow to the other Circuits 
Some designers consider balancing valves are not important because there are temperature control valve to regulate the flow in piping systems. But in the case of a few areas of design capacity is lower than the actual capacity (due to the design as construction materials, electrical equipment or an area larger design data) results are room temperature always higher threshold settings so the temperature control valve will still remain open at all times that will cause the excess flow in piping systems. That will cause the other circuits will not be enough flow so will affect the performance of air conditioning systems in other areas. 
Some designers như balancing valves are not Important Because there still are temperature control valves to Regulate the flow in the circuits. But in the case of some kế which areas where the load is the actual load less coal, (Due to the design condition như construction material, electrical equipment, or occupation are more coal the kế data) room temperature result of higher coal would always be the set point, over temperature control valves open all the times would still causing overflow to the circuits Furniture might cause underflow to the other circuits Furniture effect the loading capability of air conditioning to the other which areas. 
II - automatic balancing valve - Automatic Balancing Valves would always protect overflow 
Automatic balancing valves ensure no excess flow phenomena in the case of any other area in which the design capacity is lower than the actual capacity will therefore not affect the capacity of the system conditioning in other areas. 
Automatic Balancing Valves would always protect overflow in case of any kế which areas where the actual load is less coal load with no effect to the capability of air conditioning load at the other which areas. 
     
       ADVANTAGES OF AUTOMATIC BALANCING VALVE 
Automatic flow balance 
Higher Accuracy 
More reliable 
Low investment costs 
System operating costs low 
Save time 
Flexibility can add or remove terminal (terminal units) without the need to rebalance the system. 
Energy saving
