TOROID PRE COOLER (Patent Pending)for Air
Cooled Condensers

• Improving Cooling Efficiency
• and
• Energy Conservation
• in
• Air Cooled HVAC Systems

HVAC Rating

• Most of the packaged and central Refrigeration
  or Air conditioning systems, offered around the
  world are Air Cooled.
• The systems are labeled for rated capacity and
  performance at standard ARI conditions
• Dry bulb 95F (35.0C)
• Wet bulb 75F (23.8C)

5
Derating and System failures

• HVAC systems get de-rated by nearly 20 to 30
  or more at higher condensing temperature . They
  consume more energy to meet the design load.
• Besides derating, the compressor motors get
  overloaded due to higher head pressure and may
  burn out in many cases thus increasing
  maintenance costs.
• Lubricating oils experience chemical break down
  at higher than design temperatures.

6
Why use a Pre Cooler ?

• A large number of locations worldwide
  experience high dry bulb temperature, much above
  the ARI standard of 35C for refrigerating
  capacity rating.
• So to recoup the lost capacity due to high
  condensing temperature, some form of cooling is
  essential, especially in extreme summer climates.

Where to use TORO ID Pre coolers ?

• Summer ambient dry bulb temperature
• in dry and composite climate areas
• normally stays between 40 to 45C
• But may exceed 47C at some locations.
• Toro Pre Cooler can be used wherever the ambient
  temperature exceeds 35C for more than 1200 hours
  in a year.

11
Where are we today ?

• Under the local building code ,it may become
  essential to use pre coolers to claim building
  efficiency ratings.
• Many utility companies offer incentives for
  installing pre coolers to control load peaking in
  summer.
• Energy efficiency and water usage are major
  concern for sustainable cooling and will need to
  be addressed by these solutions.
• Can add to Leed points and better Leed rating due
  to energy efficiency.

What is TORO ID Pre Cooler ?

• Toro ID pre cooler is the only
• Two stage ,Heat and Mass transfer module
• that can cool the ambient air to below the wet
  bulb using
• 50 less water
• compared to cellulose media or any other
• adiabatic cooling process.
• It ensures that the
• condenser inlet air temperature never exceeds
• 30C
• even if the ambient dry bulb is higher than 47C
  and wet bulb reaches 28C
• At least 1 to 2C below
