Indirect Evaporative Cooling Calculation

Direct and indirect evaporative cooling are extremely energy efficient negating the need for compressors in the cooling cycle.

Indirect evaporative cooling calculation.

The exhaust air that has been cooled by approx. Energy labs has been building indirect evaporative cooling for over 30 years. 42 degrees c 23 5degrees c x 7 13 degreesc. The secondary air stream is then used to cool down the primary air in a heat exchanger.

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. 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.

Start by selecting the a geographic location the cooler will be used in and then cooler model. In the indirect evaporative cooling system a secondary air stream is cooled down by evaporating water. The elevated relative humidity after direct evaporative cooling is reduced by. Indirect evaporative cooling uses the sump water which is close to the wet bulb temperature of the atmospheric air.

The wet bulb temperature is reduced. Pmi evaporative cooling sizing calculator. Direct and indirect evaporative cooling strategies. Moisture is not added to the primary air and.

First calculate the dry bulb and wet bulb temperatures achievable with indirect evaporative cooling. To evaporate 1kg of water into an atmosphere 680w of energy is required. 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. Temp drop achievable dry bulb wet bulb x efficiency of indirect module example.

Indirect evaporative cooling systems. Temperature reduction achievable using indirect evaporative cooling and direct evaporative cooling. Our indirect evaporative cooling allows engineers and owners to get the efficiency benefit of water evaporation without concern for water carryover into the building. 8 to 10 k then flows through heat recovery in the hvac system and can then.
