We all have this experience in our daily life: when there is water on our skin, we would feel cool in the wind and in summer we feel even cooler after a hot water shower than a cold one, it is the evaporation process of water that makes this happen., when the evaporation process of water is accelerated, it will absorb the heat in the air, which makes the temperature down.

 

Taking advantage of this phenomenon “water evaporation absorbs heat and evaportation area affects the effeciency” and using  present cooling technology, we have developed our Olyda Brand Industrial Air-cooler with a body of efficient-cooling, energy-saving and environment-friendly.

 

The core element of air-coolder is a Direct Evaporating Heat Exchanger, which is a sepcially made multi-layered curved fiber material (cooling pad).

 

It features:

1.good ventilation and water absorption ablity

2.durable water-proof material, it will not change its form when soaked in water

3.high efficiency for heat exchange

4.erode-resisted, the valid period based on normal operation can be over 5 years and can lower 4-10 degree centigrade compared with outside temperature

5.excellent filtering ability to the dust in the air

 

There are mainly two types of “coolin pad”, one is Model 5090 and the other one is Model 7090, among which 5090 is more efficient, it can reach the evaperation rate of 87~93%

 

 

Water is absorbed from the water tank by a pump and then sprayed on the evaperating and filtering layer, when the outside dry and hot air enters into the cooling pad, there will be a heat exchange between the air and water, then the clean and cool air will be produced and pressed into the house or workplace by a low-noised electric fan.

 

Olyda air-cooler is suitable for open and half-open environment, it can bring the natural air as well as the cooled air into the house.

The outside air is absorbed and cooled by Olyda air-cooler and then sent into the house, which also blows out the dusty and hot air, moreoever it has the functions of air exchange, cooling and oxegen augmentation, therefore it’s quite suitable for high-temperature and crowded places.

It’s especially suitalbe for crowd and hot environment.

 

 

Olyda IA can be used in the plant of most of the traditional industries, especially those of poor working environment. For example:

1.       textile, machinery, pottery, delicate chemistry,glass, hardware, leather industry

2.       electornics, shoe-making, painting, plastics, cloting, wrapping, printing, and food industry.

3.       hospital, school, lounge room, supermarket, laundry house

4.       public place like kitchen, food market, recreation centrer, underground parking lot, bus station

5.       greehouse, flowery, poultry, livestock

6.       for location of high humidity such as textile, install our air-coolder choosefully

7.       Olyda air-cooler is not suitable for locations that require quietness, such as operation room

Example 1:  Take Guanzhou as an example

suppose：⒈Ti=34℃

            ⒉Tw=28℃

            ⒊e=92％

            ⒋Tr=37℃

            ⒌Cp=1.012Kj/kg.k

            ⒍P=1.205Kg/m3

            ⒎q=16000 m3/h or 4.44m3/s

conclusion：由湿空气含湿图(附图)中可查得当Ti=34℃、Tw=28℃时的相对湿度为59％                             

             ⒉当饱和效率为92％时,查得出风口气温可低至To=29℃

concustion：

     ⒈y=（Tr-To）/（Tr-Tw）=(37-29)/(37-28)×100%=88.9%

     ⒉Ti-To=34-29=5℃

     ⒊S=q.ρ.Cp.[e.(Ti-Tw)+( Tr-Ti)]

           =4.44×1.205×1.012×[92%×(34-28)+(37-34)]=39.24(kw)

 

Example 2： Lanzhou  Nothwest of China

    ⒈Ti=34℃

    ⒉Tw=22℃

    ⒊e=92％

    ⒋Tr=37℃

    ⒌Cp=1.012Kj/kg.k

    ⒍ρ=1.205Kg/m3

    ⒎q=16000 m3/h or 4.44m3/s

Conclusion：⒈由湿空气含湿图(附图)中可查得当Ti=34℃、Tw=22℃时的相对湿度为35％

               ⒉当饱和效率为92％时,查得出风口气温可低至To=23.2℃

Conclusion：

        ⒈y=（Tr-To）/（Tr-Tw）=(37-23.2)/(37-22)×100%=92%

         ⒉Ti-To=34-23.2=10.8℃

        ⒊S=q.ρ.Cp.[e(Ti-Tw)+( Tr-Ti)]

           =4.44×1.205×1.012×[92%×(34-22)+(37-34)]=76.02(kw)

          4. q.ρ.Cp. (Tr –T1)
