Indirect Evaporative Cooling Calculation

Indirect evaporative cooling systems.

Indirect evaporative cooling calculation.

First calculate the dry bulb and wet bulb temperatures achievable with indirect evaporative cooling. The dry bulb temperature is reduced. The exhaust air that has been cooled by approx. In the indirect evaporative cooling system a secondary air stream is cooled down by evaporating water.

Pmi evaporative cooling sizing calculator. Use the calculator below to determine the appropriate cooler sizing based on your needs. For steam humidifiers this energy typically comes from the electricity or gas being used to boil the water. In the process the air is cooled by 2 5 k per g of water absorbed per kg of air.

Refine your configuration by adjusting static pressure desired indoor temperature air change method and ceiling. Over the years we have designed systems with eer s exceeding 100. Our indirect evaporative cooling allows engineers and owners to get the efficiency benefit of water evaporation without concern for water carryover into the building. Indirect evaporative cooling uses the sump water which is close to the wet bulb temperature of the atmospheric air.

Direct and indirect evaporative cooling strategies. 42 degrees c 23 5degrees c x 7 13 degreesc. Direct and indirect evaporative cooling are extremely energy efficient negating the need for compressors in the cooling cycle. Temperature reduction achievable using indirect evaporative cooling and direct evaporative cooling.

In indirect evaporative cooling the exhaust air removed from the building is humidified as closely as possible to the 100 saturation point. The elevated relative humidity after direct evaporative cooling is reduced by. The wet bulb temperature is reduced. The technology can be applied in numerous applications including data centers factories livestock and greenhouses please refer to our industry and product pages for more information on how munters evaporative cooling technologies can provide reliable cost.

Start by selecting the a geographic location the cooler will be used in and then cooler model. Moisture is not added to the primary air and. Energy labs has been building indirect evaporative cooling for over 30 years. Temp drop achievable dry bulb wet bulb x efficiency of indirect module example.
