1、Model Selection
1, Confirm Total System Heat Rejection Capacity: Total System Heat Rejection Capacity = Total latent heat of condensing medium inside + Total heat rejection of condensing medium (For refrigeration system, it could be selected based on system refrigeration capacity)
2, Confirm the design conditions: Condensing Medium,Condensation Temperature, and Wet Bulb Temperature
3, Determine the correction coefficient ‘R’ by lookup correction coefficient table.
4, Determine Corrected Heat Rejection Capacity: Corrected Heat Rejection Capacity = Total System Heat Rejection Capacity * ‘R’ (correction coefficient).
5, Model selection: select the evaporative condenser model with rated capacity equal to or greater than the Corrected Heat Rejection Capacity.
(Take Ammonia refrigeration as an example)
1, Total Heat Rejection Capacity of the ammonia refrigeration system is 1200 kw. (Total Heat Rejection Capacity =Compressor refrigerating capacity + Compressor shaft power)
2, Operating condition: Condensation temperature 36 ℃,Wet Bulb Temperature 28 ℃.
3, Lookup ‘Correction Coefficient Table for R717’, and get the correction coefficient 1.35.
4, Determine Corrected Heat Rejection Capacity: 1200kw xl. 35 = 1620kw
5, According to ZHX model table of HAC evaporative condenser, select model ZHX-1680 as it’s the smallest one in these models with capacity greater than1620 kw.
1, The parameters in the datasheet is for reference only.
2, Operating weight is the weight of equipment full of refrigerant, and bottom water tray full of spraying water.
3, For client’s non-standard requirement, customization available.
4, The rated heat rejection capacity in the datasheet is calculated based on following design conditions: Condensing Temperature=37℃,Maximum Wet bulb Temperature=26℃.
