IntroductionTo understand the evaporative cooling process, lets consider firstthe composition of dry air.Dry air is a mixture of different gases in the following percentages:

Oxygen 20.9 % Nitrogen 78.1 %Other gases (CO2, Argon, etc.) 1.0 %

A certain amount of water is also usually contained in theatmospheric air in the form of vapour.

At usual temperature and pressure conditions the gases containedin the air do not change their state, but water can condensate orevaporate.

Some definitions will be useful to understand the concepts explained

in this manual.

PsychrometryThe branch of thermodynamics which studies the properties andtransformations of wet air.

Absolute humidityThe mass of water vapour (kg) contained in a mass unit (kg) of dryair.

Relative humidity

The ratio between the actual vapour partial pressure and the vapour partial pressure at saturation conditions. At normal temperature, itequals the ratio between the actual vapour mass and the vapour massat saturation conditions.

Hygrometer An instrument that measures the relative humidity based on thelength variation of human hair.

Dry bulb temperatureThe temperature of air measured by a thermometer freely exposed tothe air but shielded from radiation and moisture.

Wet bulb temperatureThe temperature of air measured using a thermometer that has its

bulb wrapped in a sock kept wet with water by capillary (wicking)action.

Psychrometer This device measures both the dry bulb and wet bulb temperatures.From this two data you can obtain the relative humidity from the

psychrometric diagram. Relative humidity depends on the difference between dry bulb and wet bulb temperature. The evaporation rate ofwater in the cloth depends on the quantity of water vapour containedin the air. By evaporating, the water subtracts heat, and therefore thetemperature of the wet cloth decreases.

Psychrometric diagram for humid air

A diagram showing the thermodynamic properties of humid air(humidity ratio, wet bulb temperature, dry bulb temperature, relativehumidity, enthalpy) in different environmental conditions.

EnthalpyA thermodynamic state function that represent the energy content ofthe mixture dry air-vapour at a given condition. It is the sum of theenthalpies of dry air and water vapour.

Specific heatIt is the heat required to increase the temperature of 1 kg of dry air

of 1K.

Latent heatIt is the heat required to change the state of a substance at constanttemperature. For example it is the heat required to evaporate waterfrom a liquid to vapour phase.

Adiabatic processA process in which the conditions of a system change with no heattransfer between the system and the outside surroundings.

Understanding the evaporativecoolingThe evaporation of water takes heat from the environment, thereforethe air becomes cooler. This natural process takes place without anyexternal energy supply.

ESAC evaporative coolers use this physical principle to producea sea breeze effect.

Evaporative cooling is an environmentally friendly process: norefrigerant gases are used, only a small amount of electrical energy isrequired for the fan and the pump.

Theoretical principles Evaporative cooling is an adiabatic process at constant enthalpy.It reduces the heat that we perceive ( SENSIBLE HEAT ) andincreases the heat that we do not perceive ( LATENT HEAT ), whichis removed by ventilation, without any external energy supply.

To understand this principle, please look at Fig. 1:

As you can see, using an ESAC evaporative cooler, SENSIBLE HEAT, the dry bulb temperature (the heat weperceive) is reduced, giving a sensation of comfort.

This example will be very useful to understand which informationthe psychrometric diagram can provide.

Lets suppose we measure the temperature of both dry bulb (TD) andwet bulb (TW) using a psychrometer:

TD = 36CTW = 22.2 C.

From these values we can fix the point A on the psychrometricdiagram and collect the following information:

Relative humidity = 30% Absolute humidity x = 11 g of vapour per kg of air Enthalpy of air-vapour mixture = 66.1 kJ/kg

Now, lets suppose the cooling efficiency of our evaporative cooler

is 82%. TD1 T D2Cooling efficiency = 100 (1) TD1 T W1

where:TD1 = dry bulb air temperature at inletTW1 = wet bulb air temperature at inletTD2 = dry bulb air temperature at outlet

Calculation of the outlet air temperature

From equation (1) we can calculate the air temperature at the outletof an ESAC cooler as:

(TD1 T W1 )

TD2 = T D1 _

= 36 _ 82 (36 22.2 )

100 100

The result is 24.7C.

The transformation that occurs between unit inlet and outlet isisoenthalpic, therefore we can identify point B on the psychrometricdiagram. Point B represents the conditions of air at the cooler outlet.We can therefore read the following information about exiting air :

Relative humidity = 82.5 % ; Absolute humidity x = 16 g of vapour per kg of air ; Enthalpy of the air/vapour mixture= 66.1 kJ/kg;

Air temperature at outlet of ESAC evaporative coolers

based on 82% efficiency

Water consumption

The difference between humidity at outlet and inlet allows us tocalculate how many kg of water have been transferred to each kg oftreated air.Assuming that the air density is = 1,2 kg/m 3 , we can calculate

Q = kg of water used per 1000 m 3 of air outlet

Q = (x2 x 1) 1000 = 1.2 (0.001624 0.001133) 1000

where x 1 and x 2 are the absolute humidity figures at inlet and outlet.The water consumption is 5.89 kg/h (or liters/h) per 1000 m 3/h of airoutlet.

ESAC water consumption per 1000 m 3 /h of outlet airflow

EXTERNAL RELATIVE HUMIDITY 30 % 40 % 50 % Temperatur 30 C 5.0 litres/hour 4.1 litres/hour 3.3 liters/hour

35 C 5.6 litres/hour 4.6 litres/hour 3.7 litres/hour40 C 6.1 litres/hour 5.0 litres/hour 3.9 litres/hour

Calculation of air/water heat transfer

As the process takes place at constant enthalpy, the total energycontent of the air-vapour mixture does not change: as on the

psychrometric diagram the enthalpy of the air-vapour mixture atthe points A and B is the same, but a part of the air energy content istransferred to the water.

If the vapour content of air at outlet were the same of air at inlet,the condition of air at outlet would be represented by Point C onthe psychrometric chart. The specific enthalpy difference between

points B and C represents the heat to be subtracted from each kg ofdry air to make the water evaporate. In our case the difference is

hA - hC = 65.26 - 53.62 = 11.64 kJ/kg of air.

Calculation of thermal power

Using the psychrometric diagram we have calculated the amount ofheat deducted per each kg of treated air. Based on the air output ofthe evaporative cooler, we can estimate the thermal power deductedfrom the room air.

Example : the airflow output of a FCX22T or B is 22.000 m 3/hour.From the psychrometric diagram, we read the enthalpy deductedfrom the air is 11.64 kJ/kgTo calculate the thermal capacity deducted from each m 3 of air, wemultiplying this number by the air density (1.2 kg/m 3):

11.64 kJ/kg 1.2 kg/m 3 = 13.97 kJ/m 3

We can now estimate the thermal power removed by the evaporativecooler FC 22:

P = 13.97 kJ/m3 22000 m

3/h / 3600 ~ 85 kW

This value corresponds to a specific air condition. As the outside airconditions vary, so does the thermal power.

The thermal power can also be calculated in a different way as:

P = V c p (T in T out) [kcal/h]

where : air density (kg/m 3)V: airflow rating (m 3/h)

c p : specific heat of air at constant pressure (kcal/kg/K)Tin : air temperature at inlet (C)Tout : air temperature at outlet t (C)

Using the data of the example

P = 1.2 22000 / 3600 (36 - 24.7) ~ 83.5 kW

The two results are very similar and comparable within theapproximation range of the calculations.

Evaporative cooling in practiceWater is supplied to the top of the CELdek evaporative mediavia a distribution header. The water flows down to the corrugatedsurface of the media. As the warm outside air is pulled through themedia by the centrifugal fan, a proportion of the water is evaporatedinto the air and thus cold humidified air is produced. The rest of thewater assists in washing the media, and is drawn back into the tank.The cool air exiting the unit is blown into the premise to be cooledand is distributed by means of a grill diffuser or ducting system (seeillustration).

Example: a given airflow at 36C and 30% relative humidity

flows at low speed through the evaporative CELdek pad. The airtemperature decreases and the humidity level increases, therefore thefinal conditions will be a temperature of about 25C and a relativehumidity of 82%. Cool air is conveyed into the premise, while anequal hot air flow is removed from the premise by air extractors to

balance the system.

ESAC evaporative coolers: advantages

The ESAC evaporative coolers use the simple technology of cooling based on evaporation. The ESAC units are very robust and reliableand provide large cool airflow with low installation and running costthanks to the high process efficiency.

Productivity improvementReliable research has shown that favourable climatic conditionsin working environment will improve the comfort of the workersand therefore, the productivity and the quality of the manufacturedgoods. According to a NASA report, at 32C the productivitydecrease is 29% (45% at 35C!) and the probability of errors byoperators is three times higher with respect to normal temperatureconditions (15-20C).

Continuous air renewalThe high airflow centrifugal blower provides many air renewals(typically 20-25 per hour) in the premises to be cooled.

Pure air Air is filtered through the alveolar panels, then it is conveyed into the

premises to be cooled.

Best qualityMunters ESAC is a high quality, long lasting, high efficiency unit. Corrosion-resistant unit casing (epoxy powder coated galvanized

steel, AISI 304 stainless steel, plastic).

CELdek evaporative pads with high water absorption featuresfor maximum efficiency.

The equipment is designed to maintain the best air speed throughthe evaporative pads to grant the best heat transfer between airand water.

Automatic water drain

Easy installationESAC units are self-contained, you only need to install a simplesupport frame on the wall or roof, and provide water and electricalsupply.

No special licenses or authorizations from authorities, etc. arerequired to install an evaporative cooler.

Low running costThe electrical energy consumption of the fan and water pump is verylow. Installation and maintenance costs are also very low comparedwith traditional air conditioning systems.

Simple maintenanceMaintenance is very simple as it basically consists of cleaning thewater tank, replacing the CELDEK pads and grease fan bearingsonce a year.

Water renewal

The water contains a number of soluble mineral salts whoseconcentration is measured by the water hardness. Duringevaporation only the water molecules transfer to the air stream while

the salts remain in solution in the water. The salt concentration in thecirculating water therefore tends to increase during operation.It is therefore important to renew the water in the hydraulic circuitas in the long run an excessive salt concentration could cause scaledeposit on the evaporative panel and decrease the cooling efficiency.ESAC evaporative coolers are equipped with an automatic waterdrain system, so that at every start the unit will be fed with cleanwater.

Moreover, the automatic water drain system prevents waterstagnation and the risk of bacterial proliferation.

Application examples

ESAC evaporative coolers are especially intended for the treatmentof very large air volumes.

How to choose the correct model(s)

Empirical calculation based on the number of airchangesTo choose the correct model(s) to be installed first you have to

calculate the required cool air flow.

To do this you need to know the volume of the premises to cool.The volume is obtained multiplying the area surface by the mediumheight of the premises. Should the height be greater than 4 m, for themost common applications the height shall anyway be considered to

be 4 m, as usually a temperature control is required only below thislevel.

We then multiply the room volume by the number of required airrenewals per hour. This way we obtain the necessary air flow rating,

and we are able to choose the suitable model and number of ESACunits to be installed. To summarize:

Q = S x h x r

where:Q = required airflow (m 3/h)S = surface of the premise (m 2)h = height of the premise (the height can usually assumed to be 4 meven if greater than 4 m)r = number of air renewals per hour

Lets suppose we have to install an ESAC cooler in a textile factory.The room area is 300 m 2 and the height is 8 m. Estimating that the airto treat is in the first 4 m of the premise height, the air volume to betreated is 300 4 = 1200 m 3

Assuming that 25 changes of air per hour are required, the necessaryairflow rating will be:

25 1200 m 3 = 30.000 m 3/h

For a proper installation we have therefore to choose a FCX 30(T or B) cooler. Depending on the shape of the premise it could beconvenient in some cases to install more units instead of one: in thiscase we would obviously choose two FCX 15T or B units.

The following chart suggests the models to choose for room areas upto 2000 m 3 based on 22 air changes per hour. In the event that morecoolers are required on the same installation, it is recommended touse as many units as possible of the same model in order to simplifythe installation.

The following chart shows examples of typical air renewalrequirements for some applications.

Installation guidelinesFor a correct installation and good performance of evaporativecoolers it is necessary to provide for the extraction of hot air from theroom: in practice the air conditioning works better if a fresh airflowis introduced in the building while the hot airflow is extracted fromthe room.

For this reason we strongly suggest to install evaporative coolersin combination with air extractors. They have to be placed on thewalls, on the opposite side as to the cool air inlets.

Using air extractors is not mandatory, as a certain amount of airis naturally extracted by the pressure difference between inside andoutside through openings of proper area on the walls of the room to

be cooled.It is however strongly recommended to install some extractors, as

this way the maximum airflow and consequentially the best systemefficiency are obtained. Moreover air extractors allow decreasing the

pressure inside the room to be cooled so that the removal of gases,smokes and powder is better controlled. In practice, with a lower

pressure inside the room, the air tends to enter from every openingwhile it is expelled only where the extractors are installed, so thatyou can control the expulsion of smells, etc.

On the contrary, with a higher pressure in the room, air will enteronly through the air inlet duct while the inner air will be expelledfrom every wall opening.

It is a good practice to provide for the cool air inlet at a minimum3m height to prevent disturbing air streams at the operators level.The air extractors should be positioned on the wall opposite to airinlet(s) at such a height to extract the warm stagnant air on the top ofthe room.

Some typical installation examples are sketched below:

Daily variations of temperatureand humiditySome people object that evaporative cooling is effective only wherethe weather is very dry, while the humidity level in most Europeancountries is quite high on average. However, by definition, therelative humidity tends to decrease when the temperature increases.To understand this better, keep in mind that the absolute quantityof vapour in the air do not considerably change with temperature.Again, the psychrometric diagram explains what happens during aday from the first hours in the morning till late evening.

Considering that the absolute humidity remains approximatelyconstant during the whole day, we see that increasing the dry bulb

temperature, the wet bulb temperature considerably decreases. Forexample, assuming the absolute humidity is 0.015 kg/kg of air, itfollows that at the relative humidity 25C is about 75%. At 36C therelative humidity decreases to 40%.

The following chart shows the daily variations of averagetemperature and mean relative humidity measured by the weatherstation of Verona from 1 to 10 of August 2003. It is evident thatduring the hottest hours of the day, the relative humidity decreases

below 50%. In these conditions the ESAC units work with higherand higher efficiency, and consequently produces larger and largertemperature rises, as the humidity level decreases.

Moreover, the temperature and humidity daily variations for thecooled air are smaller than the ones for untreated incoming air.This means that the ESAC units are able to guarantee a condition of

wellbeing during the whole day.
