How to compare with the large refrigeration system

The condenser of the ice making machine is really a relative crucial part when we would like to obtain an ice machine with good property, we will better to know its condenser operating condition.

There will be three chief ways to realize the condensing process:the air cooled condenser, water cooled condenser and the evaporative condenser. Regularly, we do not make use of the water cooled condenser and air cooled condenser due to its lower economic efficiency so as i'll introduce those two sorts condenser in the flowing.

Water cooled condenser:The refrigeration property can be decided by the environmental wet bulb temperature.The condensing temperature will be higher combined with the wet bulb temperature and the wet bulb temperature is 5-7 degree higher than the environmental temperature. Its temperature limit is 20-55 degree hence the condition whether you possibly can adopt the water cooled condenser depends on the environmental wet bulb temperature.

And so the consumers ought to supply the highest environmental wet bulb temperature prior to designing and at the same time, when the environmental temperature is higher than 50 degree, the cooling tower might possibly be overbasked if you used the water cooled condenser.Subsequently, the cooling tower must have been used underneath the protection of the sunshade.

The working principle:
  • The freezing medium air under high temperature and pressure will access the shell side of the condenser with the inlet where can be above the condenser.
  • The cooling water pump might extract the cooling water from the storage tank of the cooling tower, and the water can be to the tube pass through inlet where is right below the condenser and finish the heat transfer with refrigerant outside of the copper pipe of the condenser.
  • Once the water temperature becomes higher,The simply introduced of ice making machine, it would come out from the outlet in which is right above the condenser then goes into the cooling tower inlet and the water enter into the sprinkler pipe and is sprinkled on the substance equably.
  • The water temperature will certainly reduce following the heat transfer with the water in the material under the help of the fan and the water going through the cooling process shall be store in the tank for circulatory usage.

The benefits of the water cooled condenser: the refrigeration efficency might be enhanced since the condensing temperature of the refrigeration set is lower.The original cost is lower than air and evaporative cooling condenser as well as the effects is better.It is suitable for large refrigeration system,and Daily maintenance of ice block making machine compared.
