Hello scholars,
Presently am working on a design of an evaporative condenser for a refrigeration application.
Inputs available with me:
1.Typical ambient DBT & Relative Humidity for the region of application .
2. Atmospheric pressure.
3. Heat load/Condensing Load.
4. Design Condensing Temperature( 5 deg.C to 10 deg.C Higher than WBT).
5.Mass flow of refrigerant.
The evaporative condenser will be applied in an static ambient & no fans will be deployed, unless otherwise if technically required.
A pump is used to spray the water onto the evaporative surfaces to enhance evaporation.
Questions:
1. How to estimate the evaporative surface area required?
2. How to estimate the pump flow rate required?
3. How to estimate the rate of water to be refilled/ rate of water evaporation?
Looking for useful correlations/articles which can guide me for the design.
Please note:
I am designing it for a 3.5 kW Condensing load application.
DBT for the region is 45 deg.C & RH is 30%.
