The Problem

• Keeping Air Conditioning Systems in Full Capacity
  Efficiency
• The Solution
• Keeping the Heat Exchanger Tubes Always Clean

The Problem

• Cooling capacity of The majority of medium to
  large central air conditioning systems are
  designed around a re-circulating open water
  cooling systems.
• Water flow in the tubes of Shell Tube heat
  exchanger and remove the heat from the coolant
  gas.
• Water contains low solubility salts and sediments
  that deposit and build a stony scale on the inner
  tubes surfaces, causing fouling of the heat
  exchanger unit.
• Fouling of the heat exchanger unit is causing
  reduction of the Air Conditioning C.O.P
• 1mm of scale can be deposited in 2000 hours of
  operation.
• 1mm scale reduces the the system by 45

7
What is Causing Fouling? Why? How Fast ?

• Water contain minerals of Magnesium and
  Calcium that tend to deposit on hot surfaces.
• Scale, fouling sediments can be found after
  100-200 operation hours

9
The Problem

• Accumulation of stony deposits on the tube inner
  wall has a heat insulating effect that results
  in
• ? Reduction of system C.O.P and overall capacity
• ? Lower C.O.P requires extra installed
  capacity- resulting in higher
  installation cost
• ? Lower C.O.P means higher electricity
  consumption and
• maintenance costs.
• A/C system stoppage due to compressor high head
  pressure.

11
Current Design Consideration to Compensate
Fouling

• Add more capacity per unit
• Add units as backup during disassembly and
  cleaning
• Current Operational Consideration to Compensate
  Fouling
• Use more electricity for the required cooling
• Operate another system earlier
• Special maintenance to disassemble and clean the
  heat
• exchanger

Keeping Heat Exchanging Tubes Always Clean
Existing Solutions

• Chemical cleaning by acids.
• Shutting down and chemical-acid cleaning of
  the heat exchanger tubes.
• Frequent mechanical disassembly and acid
  cleaning of the heat
• exchanger tubes require excessive maintenance
  time.
• Acid can damage the tubes and the system.
• An additional backup unit is required to provide
  cooling while
• cleaning the system.
• Loss of production and cooling for days.
• Environmental problems due to the disposal of
  the chemicals.

• Ball Tech system
• It is an hydro-mechanical system,
• circulate Sponge Balls through condenser's tubes
  and keep them permanently clean.

Ball Tech system Cleaning Concept

• Features
• The system injects and collects the soft balls
  in seconds
• 100 reliable system
• Inject and Clean the tubes every 40 min
  (adjustable) totally
• avoids scale
• The Sponge Balls made of natural rubber with
  special wear resistance
• additives
• The sponge ballls diameter is 1 mm larger
  than that of the heat
• exchanger inner tubes diameter..
• Sponge Balls and condense water specific
  weight are identical.
• Sponge Ball has Excellent Flexibility
• The sponge balls enter and moves through the
  heat exchanger tubes by
• the water flow
• The sponge balls wipe off the inner tubes
  walls without disturbing the
• condense water flow.
• Balls replacements - Every 1500 Hrs of the
  chiller works.

Ball Tech system advantages

• It is a simple, reliable hydro-mechanical system.
• It keeps heat exchangers tubes permanently and
  absolutely clean.
• It is simple to install and requires no
  modification to the heat exchanger.
• The ball flow does not disturb the condense water
  flow.
• It does not impair environmental quality.
• It preserves heat exchangers C.O.P. as designed
  by the manufacturer.

20

• Saving on Air-conditionings energy consumption
  about 15 and more.
• Reduce maintenance and chemicals cost.
• It is one-time investment recoverable within one
  year.
• It prevents accelerated chillers compressor
  wear.
• Clean and simple procedures for supervision by
  any maintenance technician.

Calculation of Cleaning Reliability

• The BallTechnic system is using 30 balls for
  every 100 tubes in a pass (30 of the counted
  tubes)
• ? Can this ratio clean all the tubes?
• ? Yes, with 99.999.... reliability
• Some simple probability calculations
• ? The chance of a ball not to pass through a
  specific
• tube is 0.7
• ? There are, however, about 40 cleaning cycle in
  24Hrs
• and deposits are formed within 200 Hrs.
• ? The probability of a ball not to clean a tube
  is reduced
• over 24 Hrs. at the power of 40 is
• (0.7)40 6.3 10-7 0.00000063
• Conclusion cleaning reliability of every tube
  is proved.
• Field experience Unnecessary disassembly of the
  heat
• exchangers of systems equipped with BallTechnic
  shows 100 clean tubes with no exception

24
Ball Transfer Force

• Balls specific gravity is the same as water
• Ball diameter is 1 mm larger than tube diameter
• Pressure drop on tube is at least 1 meter (0.1
  bar) per pas
• Example
• A 20 mm tube diameter, with 0.1bar (1 meter)
  pressure difference per pass
• The force that pushes the ball through the tube
  is
• 0.1 bar x (3.14x22 cm)/4 0.315 Kg
• This pressure is much higher than is required to
  push the sponge ball through the tube.
