1. Principle of Work
SWL evaporative condenser is a piece of high-efficiency heat exchange equipment which comes into being on the basis of adopting the internationally advanced heat-exchange technology.
The evaporative condenser uses water and air as the cooling medium. Inside, there are a water dispatching system, condensing coils, wet padding heat exchange layer, dehydrator and so on. Outside, there are a pump, electronic water treatment apparatus and a propeller fan on the top of condensing coil. The propeller fan strengthens the flow of the air and causes negative pressure inside. When the evaporative condenser works, the cooling water is sprayed from water dispatching system to the surface of condensing coils equably to form a thin layer of water film. The high-temperature gaseous refrigerant enters from the top of condensing coil and then the cooled liquid refrigerant is discharged from the bottom of the coil. During this process, high-temperature refrigerant exchanges heat with the water and air outside the coil and increased heat transfer efficiency is achieved with the help of wind. After absorbing the heat of refrigerant, some water turns into steam and is discharged by the propeller fan. Meanwhile, the moisture in the hot air is collected by dehydrator to collecting basin, and then the non-gasified cooling water flows into heat exchange layer and its heat is taken away by the airflow. The cooled water converges in the basin to be used circularly by the pump later. In addition, there is a ball cock in the basin. When the water is consumed to a certain point, the ball cock will automatically open to replenish the cooling water.

4. Model Selection Guide
Instructions for Choosing a Right Model
1. Confirm conditions: condensing temperature, wet bulb temperature.
2. Calculate total heat emission amount that goes through system to condensers.
3. Take a reference to Table 2 or Table 3, select heat emission amount correction index.
4. Total amount of heat emission multiplies heat correction index equals to the condensing load during the working conditions.
5. Take a reference to Table 1, select the heat emission amount data which is bigger than or equivalent to the data after correction.
For Example:
1. Conditions: condensing temperature 36 ℃, wet bulb temperature 29 ℃.
2. Total heat emission amount of ammonia refrigeration system is 940KW.
(Compressor cooling capacity + compressor shaft power = total emission amount of heat)
3. Take a reference to table 2, heat correction index is 1.35
4. Calculate the actual load of condensers: 940KW×1.35 = 1269 KW
5. Take a reference to Table 1, select SWL-1285-type evaporative condenser, the heat emission of which is more than 1269KW.
