Intelligent Control System Solution

Flow switch, target flow switch, paddle flow switch produced by ACOL Company are all widely used in water source heat pump/ground source heat pump for water protection solutions. Tel: 021-51695568

The features of water source heat pump/ground source heat pump system:

1.The cooling capacity is small, the diameter is relatively small.
2.The cooling system is shared by many units.
3.Centralized management and control of water system.
4.If do not install the flow switch may lead to compressor failure or heat exchangers damaged by frost.

The disadvantages of traditional flow switch:

1.Traditional target flow switch built-in bellows, it is easy to fatigue, paddle easy to breakdown, the pressure is low, not exceed 10bar.
2.Condensate, easily lead to micro-switch rust and in failure.
3.The temperature must be above 0 ° C (otherwise corrugated pipe to freeze). Can not be used in the ice storage occasions.
4.Large pressure drop, up to 2-5 meters of water. consumption of the pump head, causing the water flow reduction.

Features of WFS22 Series water flow switch:

1.No bellows, the pressure can rich 25bar.
2.Micro switch and metal parts is separated, there is no rust problems.
3.The lower temperature is -20℃.
4.Pressure drop is negligible, does not consume the pump head, the unit can get the normal flow of water.

A.The paddle of traditional target flow switch is covered entire pipeline, the pressure drop is very large.
B.The paddle is very small, the pressure is negligible.

 
C.Condensation easily lead to rust, which resulting flow switch failure.
D.Micro Switch never condensed water, there is no rust problem.

If you are a design engineer of host product / design engineer of air conditioning system / engineering contractors of air conditioning, this may be that you need to consider…

The designing is the soul of quality of the products, no excellent design, there is no quality.
