Evaporative Cooling Duct Sizing

Duct sizing equal pressure method on the chart we start by drawing a line from 0 65 pa m all the way up and then draw a line across from our required volume flow rate in this case for section c we need 0 21m3 s.

Evaporative cooling duct sizing.

Refine your configuration by adjusting static pressure desired indoor temperature air change method and ceiling height. Pmi evaporative cooling sizing calculator. The next step to choosing an evaporative cooler is to find a correctly sized unit. Use the calculator below to determine the appropriate cooler sizing based on your needs.

The potential of evaporative cooling adiabatic cooling when 2 2 lbs 1kg of moisture is delivered to the air by an adiabatic humidifier 680w of evaporative cooling is achieved. To select the size of an evaporative cooler you have to consider the airflow and the size of the area you have in mind to cool. As a single adiabatic humidifier can provide up to 2 200 lbs hr 1 000 kg h of moisture from as little as 300w of electricity their potential for providing low cost adiabatic cooling in air handling units is great. When it comes to choosing a portable air conditioner one of the most important factors to take into account is the model s btu rating.

The resulted will appear to the right. A good installer retailer will also take into consideration your local humidity levels before giving you an accurate quote. You could size the main trunk line by the volume of the ducts to registers or you could just maintain the cooler outlet size.
