Two-dimensional mathematical model of the heat and mass transfer process among refrigerant

cooling water and air in the plate evaporative condenser was established on the basis of energy and mass conservation. Distributions of cooling water temperature

air temperature and air humidity ratio are obtained. And then studies on influencing factors of plate evaporative condenser heat flux

i.e.

air flow rate

cooling water spray density

air dry bulb temperature

wet bulb temperature and the condensing temperature were conducted. Simulation results were verified through experiments

and the error was less than 10%. The results showed that heat flux increased with increasing air flow rate

increasing condensing temperature and decreasing air wet bulb temperature

and is not relevant to air dry bulb temperature. With the increasing cooling water spray density

heat flux gradually increased and then kept constant. These conclusions are instructive for optimization design of plate evaporative condenser.
