Problem statement:
The company’s water cooling system has become unreliable, inefficient, and unsafe, the affected areas are unreachable and they are producing more problems rather than solving them. This system is costing more than an appropriate amount used to maintain a water cooling system. Due to bad designing this system is resulting in the cross contamination of water.
Proposed solution:
The structure of the three room’s west dock, expansion room and mechanical room is observed the main underlying problem of the system is identified. West dock and mechanical room are connected through pumps. They are working fine but in the expansion room the piping is out of order and the valves of the cooler are unreachable to the operators. Now this dysfunctional design is creating problems resulting in water contamination and is costly to repair. The proposed solution is firstly to re-design the expansion room because the main problem lies there. In the re-designing the mistakes that were previously present in the system will be minimized and solved. The availability, amount and size of valves that were creating the problem in the first place will be re-designed in such a manner that the system will be optimized for perfect cooling and the issues in reachability of the valves will be solved too. Heat exchangers will be added to the west dock, from the mechanical room with expansion rooms piping re-arranged. The heat exchange will be efficient and the temperature of the expansion room and the overall cooling system will be appropriate for both system itself and the operators of the system, covering the whole environment.
Justification:
This system is designed by expert engineers who are aware of the systems working and are expertise in this area with a work experience of more than ten years, aware of the latest technologies. Also the assigned engineers have already installed and redesigned such faulty systems in lots of companies so this is not a new task for them.
In such cases re-designing is the best option, installing the new system would be very costly and would require more space for installation, the company would not be willing for this kind of a change both financially and construction wise, so the optimum solution is already proposed above.
Negative Aspects:
It might cost more than the budget fixed for it so the company’s finance might get disturbed.
Time would be required for this whole process, the company’s work balance might get disturbed.
The expansion room’s structure might have to be re-constructed due to the valves redesigning.
During re-designing the cooling system will not work it has to be turned off during that specific time period.
Alternative consideration:
If the proposed solution is not feasible then the concept of cooling towers will be proposed to solve this problem. Cooling towers are just like water cooling systems as in they are manufactured for the same purpose as the water cooling systems. If the total cost and time of the re-designing solution is not appropriate for the company or due to some other factors the proposed solution is not feasible then this option of cooling towers can be considered.There are many types of cooling towers so the one appropriate for the present problem will be installed.
Cooling towers have several types, some that can be applied are mentioned here:
- DOUBLE-FLOW
- SINGLE-FLOW
- SPRAY-FILLED
- TYPED BY SHAPE
- RECTILINEAR
- ROUND MECHANICAL DRAFT
TYPED BY METHOD OF HEAT TRANSFER
- EVAPORATIVE
- DRY TOWER
- WATER CONSERVATION
So these cooling towers can be applied to the present system. This alternative solution can be provided to the company so that they can choose whatever option is feasible for them to apply.
