Problems with evaporative cooling in ice makers
Thread Content
How does parallel installation of chiller evaporative coolers address the issue of some evaporative coolers not performing any work?
One unit is sufficient for processing; it’s not a series connection, so there’s no significant mutual influence
The liquid levels in each ammonia cooler have been adjusted to normal levels; the flow rate of the heat medium passing through each ammonia cooler has been adjusted as well, in order to keep the temperature of gaseous ammonia in each cooler similar.
Reply to 1# szq212@163.com: It is recommended to adjust the inlet valve; controlling the condensation pressure by regulating the valve through which ammonia enters the evaporative cooler will suffice.
For ammonia coolers that do not perform work, in addition to adjusting the cooling load of each evaporator, there may be non-condensable dissolved gases; once these non-condensable gases are removed, production can be resumed
When using evaporative cooling, it is crucial to discharge non-condensable gases. It is necessary to regularly check the relationship between condensation pressure and condensation temperature; if anything is abnormal, those gases must be discharged immediately, as this has a significant impact on the operation of evaporative cooling
Generally, we observe that the pressure resulting from evaporation cooling (corresponding to the chiller load) is released at the siphon tank
Reply to 8# yg20080707: There is a non-condensable gas emitter; after recovering the ammonia component from the gas, it is discharged into the ammonia recovery system via water washing
Reply to 11# yg20080707: For specific procedures, please refer to the evaporative cooling manual; ammonia is recovered at the chiller inlet through condensation and evaporation
The ammonia we emit is used to pollute the atmosphere! ! ! Very few actually achieve recycling!
