8.0 How evaporative cooling works

1.0 Introduction:
COOL-SPACE® and our line of comfort heating products are manufactured in our
Fishers, Indiana facility.
COOL-SPACE®is a compact, self-contained, high-efficiency portable evaporative
cooler capable of lowering existing temperatures by as much as 30 degrees.
2.0 Unpacking your COOL-SPACE®unit:
Carefully examine the carton for damage before opening. If the carton is damaged, notify
the shipping company immediately.
The 16” units are shipped in a cardboard box. Open the top panel and lift unit out. The
36” units are shipped on a wooden skid stapled to a cardboard cover and lid. The
cardboard cover simply lifts off the COOL-SPACE®unit after removing the staples.
The cooler must be lifted off the wooden skid.
3.0 Set-up of the COOL-SPACE unit:
The COOL-SPACE®unit is factory tested and ready to use. The unit should be placed
on a level surface, and the casters locked to prevent inadvertent movement. Follow
instructions below to connect water and electrical supply.
3.1 Connecting the water supply:
The COOL-SPACE®unit comes equipped with a female garden hose water source
connection. Attach the unit to a standard garden hose outlet for a water source. The unit
should not be attached to any water source with operating pressure above 60 psi.
Pressures above 60 psi must use a pressure regulator which may be purchased at your
local hardware store. If you have purchased the optional portable water tank, use a
standard garden hose (not provided) to connect the tank to the cooler.

Do not connect the COOL-SPACE®unit to any water source where water pressure
exceeds 60 psi. This will cause permanent damage to the unit.
3.2 Connecting the electrical supply:
All models utilize standard 120-volt power supply. The unit should be plugged into a
fused or circuit breaker protected 20 amp, 120 volt, 60 Hz circuit. If the unit is for
overseas operation or is custom built for a specific application, please consult the factory
for proper configuration. A ground fault circuit interrupter protected circuit is strongly
recommended.
The COOL-SPACE®unit should be plugged into a fused or circuit breaker protected 20
amp, 120 volt, 60 Hz circuit. If the unit is for overseas operation or is custom built for
specific application, please consult the factory for proper configuration.
If an extension cord is required, refer to Table 2 for the proper 3-conducter heavy-duty
cord required. Table 1 shows the amperage requirements for the specific models.
Do not exceed the extension cord’s amperage ratings. Undersized extension cords result
in excessive voltage drops, which cause the electric motors to generate excessive heat.
This condition results in inefficient motor operation and premature motor failure,
WHICH WILL VOID THE WARRANTY.

4.0 Operating procedures:
There are 3 factors to consider when determining where to place the COOL-SPACE®
unit.
1. Fresh air supply: The inlet side of the unit (pad side) requires a constant,
uninterrupted supply of fresh air for maximum performance. A distance of 3 ft is
clear space is recommended.
2. Discharge air flow: The cool air discharged from the unit should be free of
obstruction to allow the air to circulate in order to maximize the cooling zone.
3. Ventilation: In order to operate at maximum effectiveness, it is helpful to have
provisions to remove the air discharged from the COOL-SPACE®unit from the
cooling area. This ensures that the COOL-SPACE®unit does not recirculate air that
has already been through the evaporative cooling process.
The COOL-SPACE®unit must be placed on a level surface to operate correctly. The
units create an oval shaped air pattern that can reach out as far as 70 feet with large fans.
Obstacles such as racks and workbenches may interfere with the cooling zone. An
attempt should be made to locate the unit in such a manner that interruption of the air
pattern is held to a minimum. Multiple units may be required to cover larger areas.
When the COOL-SPACE®unit is placed near a wall or other vertical obstruction, it is
recommended that there be a space of at least 3 feet between the back (pad side) of the
unit and the obstruction. This ensures that a clear supply of fresh air is able to get to the
inlet of the unit.
A platform or framework may be built to support the COOL-SPACE®unit in order to
place the unit out of the way of obstacles. When constructing a framework, ensure that it
will not allow the COOL-SPACE®unit to tip over. Also, the structure must be able to
accommodate the unit plus the added weight of the water in both the pads and the
reservoir.
16” Unit: 84 lbs. (unit) + 24 lbs. (pad operating weight) + 120 lbs. (15 gal. reservoir) =
228 lbs.
36” Unit: 295 lbs. (unit) + 60 lbs. (pad operating weight) + 384 lbs. (48 gal. reservoir) =
739 lbs.
48” Unit: 497 lbs. (unit) + 100 lbs. (pad operating weight) + 512 lbs. (64 gal. reservoir) =
1,109 lbs.

4.1 Filling the unit with water:
Once the COOL-SPACE®unit has been hooked up to a water source as described in 3.1,
turn the water supply valve on and the unit will fill with water. The float valve will shut
off the water flow when the sump is full.
4.2 Starting the fan:
Turn the fan switch HIGH speed on start-up, allow motor to reach maximum speed, then
set at Medium or Low.
DO NOT flood the pads with water, keep them moist. New pads take a few days to
become completely saturated. It is normal to have several dry streaks on the face of the
pads about 1 or 2 inches wide. If the streaks are larger or unevenly spaced, adjust the
flow control knob to allow more water to flow to the pads. NOTE: New pads may also
emanate an odor under initial operating conditions from the resin used to construct the
media. Flush the pads by running the pump without the fan running for approximately 2
hours. Empty the sump and refill. Repeat if odor still exists.
4.3 Starting the pump and adjusting the water flow:
NOTE: Have fan running while adjusting the water flow.
Once the sump is full, the pump switch may be turned to the ‘ON’ position. The flow
control knob will need to be adjusted on initial start-up. It is located at the right side of
the unit, it controls the volume of water that is delivered to the top of the cooling pads.
Do not operate the pump when the sump is dry. This will cause the pump to fail and void
the warranty.
5.0 Maintenance and storage:
ELECTRICAL SHOCK HAZARD
Disconnect the power supply
before performing any service or
maintenance on the unit. Failure
to do so may result in serious
injury or death.

The COOL-SPACE®unit is constructed of durable industrial grade components and
requires minimal maintenance. The housing is constructed of corrosion-free
polyethylene. The fan is galvanized for corrosion resistance. The motor is TEAO
moisture resistant specifically designed for wet applications. All other components are
designed for wet duty applications to ensure long life of the unit.
5.1 Removing the cooling media to access the inside of the unit:
In order to perform any maintenance on internal components, the cooling pads must be
removed to access the inside of the unit.
1. Use a wrench to remove the (2) bolts connecting the pad retainer (pad side) to the
housing.
2. Each pad can be tilted out of the unit and lifted out of the drain tray.
Note: Reinstall pads correctly.
5.2 Daily maintenance:
When shutting down the COOL-SPACE®unit at the end of each workday, the pump
should be turned off approximately 15 minutes before the fan is turned off. This will
allow the pads to drain and dry out. This simple guideline will ensure long and efficient
pad life as well as help to control mildew and bacteria growth.
Shut off pump 15 minutes before shutting off fan to allow pads to drain and dry out. This
will help pad life and operation and control mildew growth.
5.3 Periodic maintenance:
Depending on how often the COOL-SPACE®unit operates, this procedure should be
performed anywhere from every week for heavy use to monthly for light use. Shut down
the unit and drain the water sump. The cooling pads act as a filtering agent and remove
dust and other particles from the incoming air stream. These particles will flow into the
sump and collect there. Also, impurities in the water will collect in the sump.
1. Close the water flow valve and open the drain valve.
2. Run pump until sump is dry then immediately shut off pump.
3. Turn unit off and disconnect power supply.
ELECTRICAL SHOCK HAZARD
Disconnect the power supply
before performing any service or
maintenance on the unit. Failure
to do so may result in serious
injury or death

4. Remove cooling pads, refer to 5.1.1.
5. Clean out reservoir with either a towel or wet/dry vacuum.
6. Check belt for tightness, if applicable.
7. Remove the water spray bar, remove its plug. Using pump flush tube and insure
holes are free of debris.
8. Reinstall pads and pad retainer.
9. Reinstall back guard (if applicable).
To keep the COOL-SPACE®unit operating at peak efficiency, ensure that the cooling
pads are kept clean and dust-free. Dust and other particles have an adverse effect on the
media’s ability to introduce water into the air stream. If the pad surface becomes dirty or
dusty, clean with a soft brush and water.
The fan motor may require periodic lubrication depending on the COOL-SPACE®
model. Check your model for an oil fill location on the motor. A few drops of light oil
each year will extend motor life.
5.4 Storage:
1. Remove the pads, as described in 5.1.1, clean with a soft brush and water to remove
dust and debris.
2. Drain sump using above procedure and wipe dry.
3. Store the COOL-SPACE®unit in a dry area and cover if possible to prevent dust
build-up.
6.0 Troubleshooting/Repair:
6.1 Troubleshooting:
The COOL-SPACE®unit consists of three systems, it is important to determine which
system of the COOL-SPACE®unit the problem is associated with. This may not always
be obvious, in that certain problems may be associated with more than one system.
When determining which system has a problem, you must define associated problem,
(i.e. the pump is not running). Although this might seem a bit simplified, several things
may cause this particular problem. So while defining the problem, a careful check of all
systems should be made to fully understand the extent of the problem.
ELECTRICAL SHOCK HAZARD
Disconnect the power supply
before performing any service or
maintenance on the unit. Failure
to do so may result in serious
injury or death

If you have a complete understanding of all of the systems of the COOL-SPACE®unit
and how they depend on each other, it will be simple to define and solve any problem.
Although the COOL-SPACE®unit is designed to be simple to maintain, it will be
necessary to have some basic hand tools (screwdrivers, pliers, adjustable wrenches, etc.)
as well a volt/ohm meter when troubleshooting the electrical system.
Fan System
CAUTION: Please use caution when troubleshooting or repairing all electrical
components. Be certain that all power is disconnected from the COOL-SPACE®
unit before the cooling pads or fan guard are removed to gain access to the fan.

Dry-bulb temperature is measured
with an ordinary thermometer.
Dry-bulb temperature lines on the
psychrometric chart are the vertical
lines shown in Figure 1.
Wet-bulb temperature is measured
using a wet-bulb thermometer,
which is an ordinary liquid-in glass
thermometer whose bulb is
enclosed by a wick moistened with
water, often called a sling
psychrometer. The psychrometer is
whirled around in the air. If the air
is not saturated (100% relative
humidity), the water in the wick
evaporates and the water
temperature falls below the dry-
bulb temperature. Figure 2 shows
the wet-bulb temperature lines on
the psychometric chart.

8.0 How evaporative cooling works:
In order to have an understanding of how the COOL-SPACE® portable evaporative
cooler works a basic understanding of psychrometrics is necessary. Psychrometrics is the
branch of thermodynamics devoted to the study of air and water vapor mixtures. The
psychrometric chart is a graphical representation of properties of moist air. To illustrate
how the COOL-SPACE®unit operates, some of the relevant properties are described in
this section followed by a sample application.
Figure 1.
Figure 2.

Dew-point temperature is the
temperature to which a given
sample of air must be cooled so
that moisture will start condensing
out of it. When air is saturated, the
dry-bulb, wet-bulb and dew-point
temperatures will all be equal. The
horizontal lines in Figure 3 show
the dew-point temperature on the
psychrometric chart.
Relative humidity is the amount of
moisture in the air relative to the
amount of moisture the air would
hold if saturated at that dry-bulb
temperature. Percent humidity is
not the same as relative humidty
and is not used in HVAC design.
Figure 4 shows the relative humidy
curves on the psychrometric chart.
The following example illustrates the use of the psychrometric chart as it relates to
evaporative cooling. Since all of the items described above are properties, any two of
them describe a state point on the psychrometric chart. Once this point is determined,
the values of all the other properties can be read from the chart. Figure 5 below shows a
Mollier type psychrometric chart for atmospheric pressure.
The dot shown in Figure 5 is a state point. The following properties are known about
the air/water mixture at this state.
dry-bulb temperature: 97°F dew-point temperature: 71°F
wet-bulb temperature: 78°F relative humidity: 43%
Figure 3.
Figure 4.

The COOL-SPACE® unit is a high-efficiency portable evaporative cooler. The unit
draws air across water saturated high-efficency cooling pads which forces the air to
evaporate the water, thus removing energy from the air.
Take the air/water mixture described by the state point above, with a dry-bulb
temperature of 97°F and 43% relative humidity, for example. As the air passes through
the cooling media on the COOL-SPACE® unit, moisture is added to the air increasing
the relative humidity. This increase in relative humidity brings a decrease in dry bulb
temperature. When the relative humidity is raised to 70%, the dry bulb temperature has
dropped to 86°F. When the humidity level approaches 100%, the dry bulb temperature
has dropped nearly 20°F to 78°F.
