Indirect Evaporative Cooling Calculation

Temperature reduction achievable using indirect evaporative cooling and direct evaporative cooling.

Indirect evaporative cooling calculation.

Over the years we have designed systems with eer s exceeding 100. The exhaust air that has been cooled by approx. Energy labs has been building indirect evaporative cooling for over 30 years. Direct and indirect evaporative cooling are extremely energy efficient negating the need for compressors in the cooling cycle.

Pmi evaporative cooling sizing calculator. 8 to 10 k then flows through heat recovery in the hvac system and can then. Refine your configuration by adjusting static pressure desired indoor temperature air change method and ceiling. Indirect evaporative cooling uses the sump water which is close to the wet bulb temperature of the atmospheric air.

Start by selecting the a geographic location the cooler will be used in and then cooler model. 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. To evaporate 1kg of water into an atmosphere 680w of energy is required. Direct and indirect evaporative cooling strategies.

Moisture is not added to the primary air and. The dry bulb temperature is reduced. Indirect evaporative cooling systems. In the process the air is cooled by 2 5 k per g of water absorbed per kg of air.

The secondary air stream is then used to cool down the primary air in a heat exchanger. The wet bulb temperature is reduced. In the indirect evaporative cooling system a secondary air stream is cooled down by evaporating water. Use the calculator below to determine the appropriate cooler sizing based on your needs.

In indirect evaporative cooling the exhaust air removed from the building is humidified as closely as possible to the 100 saturation point. For steam humidifiers this energy typically comes from the electricity or gas being used to boil the water. 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.
