How swamp cooler works

How it Works

A swamp cooler uses the basic principle of evaporation along with simple technology and electrical power to create cold airflow. First, one motor pumps water into pads of a fibrous, absorbent substance similar to hay, called cellulose. Then another motor powers a fan that pushes air through the pad, which is always pregnant with fresh water.

Benefits

Not only does a swamp cooler lower the temperature of the air, it also makes the atmosphere more pleasant. The chilled air is slightly damper and always freshly recirculated. This gives the swamp cooler many advantages over an air conditioner

Features to look for when buying an air conditioner

We made our own evaporative air conditioner and so can you. We have put together a nice set of instructions showing how we made our air cooler. The instructions are simple and easy.

Aolan( FUJIAN) Enterprise Co., Ltd

This picture shows a typical window mounted evaporative cooler, also called a swamp cooler. Inside this unit, a centrifugal blower pulls air through the pads of the housing, and discharges it into the space to be cooled through the box-like opening in the front. Switches on the front panel usually control blower speed (HI-MED-LO) and a small pump motor inside the housing. A water line supplies water to a shallow reservoir in the bottom of this unit. As water evaporates, addition of make-up water is controlled by a simple float-valve.

How do I know if a swamper will work for me?

The easiest, rule-of-thumb, way to tell if you will be satisfied with a swamp cooler, is to visit your local building supply and home improvement center or hardware store. If they do not stock evaporative coolers and the parts to maintain them, it's most likely because there is not a big demand in your area.

Home cooling

Evaporative coolers are energy efficient since the blower motor only has to move the air and not compress a refrigerant gas as required in an air conditioner. The blower motor in a residential unit is typically 1/3 to 3/4 horsepower, while water pumps may be smaller than 1/20th horsepower. When compared to 3 and 5 horsepower compressors needed for refrigerated air, plus the fans for cooling and condensing, evaporative coolers require only about one-tenth as much energy for home cooling, a large annual saving on your electric bill.

The key to efficient evaporative cooling

The key to efficient evaporative cooling lays with the design of the cooler pads and relative humidity of the ambient air. While little can be done to control humidity outside the home, much research has gone into the design of cooler pads and materials. Aspen pads are effective and inexpensive, easy for the home owner to change, and are biodegradable when disposed of properly.

This is where you will find answers to many frequently asked questions (FAQs), and other useful information regarding evaporative cooling and Aolan evaporative coolers.

Maintaining Your Evaporative Cooler

Some consumers are turned off by evaporative swamp coolers because they think they're more difficult to maintain than air conditioners.  While swamp coolers do require periodic maintenance, this usually only involves draning and cleaning the unit in order to prevent sediment build-up. 

However, also keep in mind that the more frequently you use your swamp cooler, the more maintenace it will need.  In hot, dry climates, you'll probably be using the unit several hours a day.  If this is the case, remember to check the unit's filters, reservoir, pump, and pads regularly.  Doing so will ensure proper cooling and years of hassle-free operation. 

Small evaporative air coolers

· Small evaporative coolers can be often placed in windows, much like a window air conditioner. This requires very little installation. Larger units usually require ducts to distribute the air, but these can be an existing forced air duct system in the house. 

Evaporative cooling adds moisture?

Many people appreciate the fact that evaporative cooling adds moisture to the air, which helps to keep wood furniture and fabrics from drying out. The moist pads through which the outside air flows are also fairly efficient air filters, trapping some dust and pollen. Since the pads are continually wetted, trapped particles are flushed out and trapped in the bottom of the cooler

Drawbacks to Evaporative Cooling

The main drawback of swamp coolers is that they depend on dry outside air to operate effectively. This is usually not a problem for most of California, which has a desert or Mediterranean climate. On hot, muggy days in the summer, however, swamp coolers will blow hot, humid, soggy air into the house. If the humidity stays high for several days, the moist pads that make the evaporative cooler work can begin to smell, and the musty odor can be blown into the house.

Evaporative air cooler's market

Evaporative coolers are now on the market that use photovoltaic panels to create the electricity used to run the blower and the water pump. For hot, desert areas, the combination of evaporative cooling and solar power are a perfect match: the afternoon, when the most solar energy is available, is also the hottest part of the day, when cooling is most needed. And since swamp coolers use a fraction of the energy of air conditioners, PV cells can provide enough electricity to run the system effectively. 

Evaporative Air Cooling Create Comfort

* Lowers actual temperature. Properly installed, the cooler provides 
a continuous flow of cool air that lowers actual room air temperature.

* Lowers effective temperature. Rapid motion of the cool air increases 
skin surface evaporation. This results in body heat loss and lowers 
effective temperature (temperature you actually feel) and additional 
three to five degrees.

* Reduces radiated heat. The constant flow of cool air absorbs heat 
from all exposed surfaces and results in a reduction of heat radiated to 
the human body.

* Provides 100% fresh air.

* Filters air. Removes dust, pollen, and foreign matter. Helps controls 
allergies.

The Advantages to Evaporative Air Cooling

* Low cost of operation and maintenance

* Maximum comfort when needed. The hotter the day, the greater the 
cooling.

* 100% fresh, filtered air.

Low price and high quality coolers in China

Low price, very effective in low humidity. Has a strong fan when not using the cooling feature. Timer works well. Has an oscillating feature,  A plastic body that cannot rust like those made of sheet metal or tin.
It's been in the high 90s to the low 100's here in the China, with low humidity and it's kept whatever room it is in cool enough to not have to turn on the AC.
It's no air conditioner, but it's a low in cost [to purchase and to run]alternative you could even say was an "eco-friendly" way to stay comfortable in the summer. But then, my friends had to talk me out of buying a wringer washing machine, so my opinion is based on my personal preference for simplicity and old fashioned ways of doing things.
Take my review as you will. It does what it says it will. If you have frequent high humidity, it won't be effective and the company tells you that so be forewarned. I find it to be a great buy and it runs quietly as well.

Description of Air coolers

This Evaporative Air Cooler, Humidifier, and Fan is versatile, lightweight and economical. The Cooler easily rolls from room to room for use anywhere in your house or office.

 

This Air Cooler shoots a stream of air with oscillating louvers, to evenly distribute refreshing cool air. Can also be used as a fan or humidifier if temperature is not an issue. The remote control allows you to easily change settings.The Air Cooler works by endothermic reaction (a reaction that consumes heat), 

 

 As the air flows through the wick, some of the water evaporates into the air, consuming the heat that was in the air. An air stream is then blown out the front of the unit and is considerably cooler than the current room temperature! This is not an air conditioner and therefore uses much less energy

 

The unit works well in dry climates; not very effective in areas with high humidity as the unit utilizes water to cool.

Air coolers in China

Versatile, lightweight, and economical, this evaporative air cooler easily rolls from room to room for use anywhere in the home or office.

Unlike a fan that blows hot air and more energy efficient than an air conditioner, the appliance uses water to cool a personal space up to 12 degrees lower than the ambient temperature.

The air cooler works by endothermic reaction (a reaction that consumes heat). The unit sucks air through a wick saturated with water; as the air flows through the wick, some of the water evaporates into the air, consuming the heat that was in the air.

A cool air stream then gets blown out the front of the unit through oscillating louvers for even distribution.

Environmental friendly air coolers

Eco-Cooler Jet Stream Range
250 to 750 Watt.
This system has beenmanufactured for ease of use. It is an air-cooled system based around the rising
sun super reflector. It has 2 x 125mm flanges. One is mounted on the ignitor housing,
which has small holes punched on one side and 4 large jet holes on the lamp holder
side. At the opposite end of the reflector there is one large hole with a 125mm flange.
round the bottom of the reflector is a heavy duty galvanised frame which houses the 4mm toughened
safety glass, which has a Class A impact performance to BS 6206 and offers greatly increased resistance to sudden temperature changes compared with annealed glass.
   
 It can also be used in service within the temperature range from 280 degrees
Celsius down to minus 70 degrees Celsius without affecting its performance and can also
withstand sudden shock temperature of approximately 200 degrees Celsius.
If ever the glass is broken it disintegrates into relatively harmless small pieces.
This framework has a rubber seal to protect the glass edge and to seal the whole unit so that
the hot air is never in your room. The framework drops down via two wing nuts and slides to one
side for easy cleaning of the glass.
The air blows vi the ignitor housing and out over the length of the lamp through the flange at
the other end of the reflector.
Recent tests showed that with an anbient temperature of 20 degrees Celsius, and using a 600
watt system with a 125mm extractor fan, the temperature recorded was 27 degrees Celsius at a
distance of 0.5 metre below the glass.
The Eco-cooler Jet Stream systems are manufactured to a high standard using quality components.
All control boxes are manufactured from 1mm steel and are epoxy powder coated in blue.
All boxes are vented at the top and bottom to allow airflow to ensure cool running, giving a
longer component life.
All Eco-Cooler Jet Stream systems are manufactured in accordance to BS EN 60598-1.
The external cable is manufactured from rubber neoprene 1.5mm H07RNF. The internal wire is
high temperature silicone 1.5mm.
These systems come with 2 metres of cable from the moulded plug into the box and 4 metres
out of the box to the reflector. Longer lengths can be built into the system upon request, which
will be charged at cost.
These systems can be remoted as far as 150 metres!
This system comes with a choice of reflectors of a parabolic design. The material is highly
polished anodised dimpled aluminium with a vented 3mm aluminium heat sink running along
the top of the reflectors to draw heat away from the lamp. The reflectors give a very even spread
of light.
The ignitor is mounted in it's own housing behind the lamp, which is detachable from the
reflector via two wing nuts for ease of use.
These systems can be manufactured for almost any electric supply.
Re-strike of hot lamps on mains failure
This is dependent on temperature and lamp type.
The re-strike time is between 30 seconds and 20 minutes. If the lamp is not relit after 20
minutes, then the system will shut down as the lamp is obviously faulty.
Eco-Cooler Jet Stream comes with a 4 year warranty on all components excluding the lamp, so
long as the equipment has not been tampered with or altered in any form.
These systems are supplied with a choice of Sylvania Grolux or Osram Nav-t super lamps. They
are also suitable for use with metal halide lamps with the exception of the 750 watt

Evaporative Air Cooler

 

Overview Of Evaporative Air Coolers

If you ask an older relative if they have heard of an evaporative cooler, they may say no. But chances are they would recognize the idea behind the technology. Before air conditioning or other cooler types existed, people would sleep outside on a screened in porch to try to stay cool at night. They would often hang damp sheets over the screens in an attempt to cool the air. As the hot air passed through the sheet, it was cooled. And then the cool air would slowly circulate, relieving some of the heat for the sleepers.

How Evaporative Air Coolers Work

The same idea exists today in the form of evaporative coolers. These machines are wonderful cooling mechanisms for people who live in hot, dry climates. They are also known by the name swamp coolers, but that can be misleading because they actually won't work at all in swampy, humid conditions. The name probably came from the way that evaporative coolers actually add humidity to the air. But in fact, evaporative coolers need dry, hot air to work because in order for the air to be cooled, it has to be able to pick up (evaporate) some of the water. If the air is already saturated, it won't pick up any more water and it won't be cooled.
Here's how evaporative coolers work; the machine is composed of a fan that pulls the hot dry air inside the cooler, where it is passed through damp pads. The pads are kept damp by a pump that circulates water through the machine. As the dry air picks up some of the water, its temperature drops, sometimes by as much as 30 degrees Fahrenheit, depending on the climate. The cooler air is then blown into the room. An added bonus of an evaporative cooler is that the pads that cool the air also filter it. As the air passes through the pads, dirt, dust, allergens and other pollutants are captured in the fibers of the pads. So you'll be breathing cleaner, cooler air.

Choosing an Evaporative Air Cooler over an Air Conditioner

If you're wondering why you should choose an evaporative cooler over a traditional air conditioner, there's one more reason we haven't covered yet. The cost to run an evaporative cooler can be as little as 1/10 the amount it costs to run an air conditioner. In fact, some community power companies in hot, dry climates will actually offer residents a rebate if they install an evaporative cooler because they recognize the effective, efficient cooling capabilities of the technology. Contact your local power company to see if they offer the rebates and ask if they have any information on the effectiveness of an evaporative cooler in your area.

Benefits of air coolers-AOLAN

                                      Environmental Benefits  
Evaporative cooling provides 100% fresh, cool air continuously while traditional
refrigerated air conditioning utilizes a closed system that recirculates the same stale
dry air over and over. Constant air movement of the evaporative cooler pushes hot
air out removing dust, pollen, smoke, odor, and pollution and replaces it with cool
fresh air.

 Unlike air conditioning, evaporative cooling does not require an airtight structure to operate at maximum
efficiency. In fact, you need to allow your home to "breathe."  Opening doors and windows or installing Up-
dux™ vents to let air escape to the attic properly ventilates your home.

Evaporative cooling is also an environmentally-friendly alternative to air conditioning since it has no CFC's
or HCFC's.
Energy SavingsEvaporative coolers use 70% less power than air conditioning.
Example:
A 1500 square foot home is located in Phoenix, Arizona where the dry bulb temperature is 107, the wet
bulb temperature is 71, and the wet bulb depression is 36.

Air Conditioner
Assuming air conditioning supplies 500 square feet of cooling per ton, 3 tons of air conditioning would be
required to cool a 1500 square foot home. Since an air conditioner would probably run most of the time in
this climate, its electric usage would be approximately 3.6 Kw per hour depending on your utility.

Evaporative Cooler
Using an Essick, Champion or Tradewinds cooler with a minimum of 5000 CFM and ¾ horsepower motor,
total power consumption (motor and pump combined) would be approximately 0.991 Kw per hour.

Results
If the air conditioner and the evaporative cooler ran for a comparable period of time, the ratio of energy
for the evaporative cooler to the air conditioner would be 0.991 Kw per hour to 3.6 Kw per hour, or 0.275.
This means the evaporative cooler would use 72 ½% less power than an air conditioner to cool the same
area in the same environment.

Energy Cost Savings
Assuming a new energy cost of .14¢ per Kwh, this comparison would result in a possible net savings of
($362.88 - $99.89) = $262.99 each month! With this type of savings, evaporative coolers are a significant
cost effective alternative to air conditioning.ir movement of the evaporative cooler pushes hot
air out removing dust, pollen, smoke, odor, and pollution and replaces it with cool
fresh air.

Product Overview

Introducing the EcoCooler™ Product line
The EcoCooler™ is the only alternative to water-based evaporative air coolers and the problems they have -- the swamp smell, the raised humidity, breeding ground for insect, the constant dripping, filling and mess! The EcoCooler™ uses a waterless patent-pending cooling chamber with a hybrid technology. The Cooling Chamber uses a high-density cold air that offers more cooling capacity than conventional air cooler.

With a powerful oscillating fan that pulls the air through the frozen cooling chamber, the EcoCooler™ acts as a tremendous supplement to your central air or window air conditioner. Since the EcoCooler™ is water less; it adds absolutely NO humidity to your air like other evaporative water-based swamp coolers. Why use a water-based cooler that adds humidity to the air that your central air just has to remove to cool your house? With the EcoCooler™ waterless air cooling design, your air conditioner now has a true cooling companion.

Consider the benefits of using the waterless EcoCooler™ with your whole-house or window air conditioner:

• Adds NO humidity so your air conditioner doesn't have to work even harder
• Can be used throughout the India, including humid climates
• Supplements cooling so you can reduce the use of your central air conditioner, window ac and electricity
• Focuses cooling where you are so you can minimize the use of central air conditioning

Compare it to standard water-based air coolers:

• No swamp cooler smell
• No messy refilling
• No chance for leaks, dripping, and other potential water-damage problems
• No increase in the humidity in the room
• Waterless means NO water needed -- that saves money and doesn't waste the environment's most precious resource
• No water also means the EcoCooler™ is the most portable air cooler on the market
• No water also means no breeding ground for insect, especially for mosquito’s

• Waterless cooler uses Aire1Cooling Chamber
• HEPA-filter included
• Oscillating fan for cool air distribution 

Enegry-saving air cooler

Evaporative Cooling Free Air System

How are the savings achieved?
An Aolan cooler free air system provides a constant flow of attemperated air between 25°C and 30°C.  No refrigeration is used – the air is cooled by evaporative cooling when ambient temperatures are high and is heated by recirculation of air from the server exhaust when the ambient temperature is low.  No refrigeration is used as all of the cooling is achieved using evaporative cooling.  This results in energy saving in excess of 90% compared with traditional Computer Room Air Conditioners (CRAC’s)

1 – Fresh air is brought into the system though primary filtration and wetted filter pads
2 – Evaporative cooling operates during warm periods
3 – Low energy axial fan air distribution
4 – Patented control system controls air supply temperature
5 – Air flow is matched to density of cooling required
6 – Hot and cold aisle arrangement of racks is preferred
7 – Room is kept at a positive pressure
8 –Ceiling void can be used for exhaust path.
9 - No exhaust fans are used to reduce complexity and energy use
10 - Hot air is exhausted to atmosphere

System Design

The air flow required of the system is dependent upon the total IT load and the server design.  Using a typical ΔT of 10C a single Aolan cooler  CREC can support a load of 35kW.  The systems can be either fixed or variable flow.

The low energy air distribution system uses axial fans which can accommodate most applications.  Where raised floors are used, the overall design, in particular the floor grill numbers and position, should reflect the pressure drops and rack cooling load density.

Most systems are controlled centrally.  This allows fully automatic control and identification of any fault conditions.

Server and IT operating conditions

The following must be taken into account when providing a cooling solution:

Temperature:  In Europe an Aolan Cooler  can provide 100% compliance against the latest ASHRAE[1] standards and meet all manufacturer environmental specifications. Some early main frame systems require close control and evaporative cooling is not suitable.

Relative Humidity:  In Europe an Aolan Cooler can provide 99% compliance against ASRAE allowable conditions.  Older equipment such as paper tape and magnetic tape systems are less tolerant and evaporative cooling is not suitable.

Dust:  The filter pads provide an adequate level of filtration for modern IT equipment with sealed bearings and closed drives.

Redundancy – The required redundancy is met using the modular system.
