We all are aware of domestic fridge too its usage. We larn H2O ice cubes from freezer compartment to encounter daily requirements but to larn H2O ice inwards huge quantity nosotros commonly approaches the H2O ice found or factory. Here, I am going to percentage overview of structure too working of H2O ice making procedure too its layout.
Normally, whatever refrigeration organisation consists of iv psyche equipments:
1. Compressor
2. Condenser
3. Throttle valve/flow command valve
4. Evaporator

But inwards Ice found or factory, 2 additional circuits attention us to exercise H2O ice inwards huge quantity. Refer to the figure too Video.
Construction too Working of Ice plant:
It basically consists of iii psyche circuits.
- Refrigeration Circuit (Working fluid, Ammonia, Primary refrigerant)
- Cooling Water Circuit (Cooling water)
- Brine Circuit (Brine solution)
In Refrigeration Circuit, compressor increases the boiling signal of depression pressure level vapor refrigerant i.e. Ammonia to high pressure level boiling signal ammonia (so that it tin hold out easily condensed at room temperature) too sends it to condenser via discharge line.
Here, room temperature H2O coming out from the cooling H2O circuit/cooling tower condenses the high pressure level vapor too converts it to high pressure level liquid ammonia.
High pressure level liquid ammonia is stored inwards reservoir or receiver too forwarded to confine valve or menstruum command valve where, high pressure level refrigerant is converted to low pressure level liquid refrigerant (to decrease the boiling point) too then that at depression pressure level status inwards evaporator, it tin hold out easily vaporized from the estrus of stuffs to hold out cooled. This procedure is called throttling.
Now, depression pressure level liquid ammonia passes through evaporator (a estrus exchanger) where it is converted to the low pressure level vapor yesteryear estrus obtained from brine solution. Brine solution circulates itself from brine tank to evaporator too cools the H2O kept inwards H2O ice tin below goose egg marking centigrade to arrive inwards H2O ice form. Here, brine solution is likewise a refrigerant but every bit it does alter the stage during estrus transfer betwixt H2O too evaporator, it is called secondary refrigerant. On the other hand, Ammonia is primary refrigerant every bit it undergoes stage alter during cooling process.
