Indirect Evaporative Cooling Calculation

Indirect evaporative cooling systems.

Indirect evaporative cooling calculation.

Temp drop achievable dry bulb wet bulb x efficiency of indirect module example. In the indirect evaporative cooling system a secondary air stream is cooled down by evaporating water. The exhaust air that has been cooled by approx. 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.

Energy labs has been building indirect evaporative cooling for over 30 years. 8 to 10 k then flows through heat recovery in the hvac system and can then. First calculate the dry bulb and wet bulb temperatures achievable with indirect evaporative cooling. The elevated relative humidity after direct evaporative cooling is reduced by.

Direct and indirect evaporative cooling are extremely energy efficient negating the need for compressors in the cooling cycle. 42 degrees c 23 5degrees c x 7 13 degreesc. Start by selecting the a geographic location the cooler will be used in and then cooler model. Use the calculator below to determine the appropriate cooler sizing based on your needs.

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. To evaporate 1kg of water into an atmosphere 680w of energy is required. Direct and indirect evaporative cooling strategies.

Indirect evaporative cooling uses the sump water which is close to the wet bulb temperature of the atmospheric air. In the process the air is cooled by 2 5 k per g of water absorbed per kg of air. For steam humidifiers this energy typically comes from the electricity or gas being used to boil the water. In indirect evaporative cooling the exhaust air removed from the building is humidified as closely as possible to the 100 saturation point.

Pmi evaporative cooling sizing calculator. Moisture is not added to the primary air and. Our indirect evaporative cooling allows engineers and owners to get the efficiency benefit of water evaporation without concern for water carryover into the building. The dry bulb temperature is reduced.
