Utilities such as Steam, Compressed Air and Refrigeration & Air Conditioning are very crucial for the process. These utilities are often very expensive to operate and form a substantial part of the total energy cost. They also have a major influence on the processes that use them, often affecting the throughput rates, quality and the cost of manufacture.
Refrigeration systems are required the process plants such as Chemical, Food Processing, Dairy industries etc. to meet the process chilling loads. However, Air Conditioning Systems are used for comfort cooling for Office or Commercial buildings, and for maintaining the desired ambient conditions for demanding processes.
These utilities contribute to substantial energy costs. Following opportunities may exist in view of energy cost reduction:
- Optimising the load requirement
- Proper controls
- Proper selection of the type of the system
- Optimal system design
- Complete revamp of the old and inefficient system
- Reduction in specific power consumption through efficient generation
