Abstract:
This research aimed to reduce the energy cost of a sample beverage factory. It began with a study of an overview of energy consumption and the energy characteristics of the production process and arranged each production process's energy consumption within a sample beverage factory for analysis and offering a cost reduction method. The implementation has both non-investment and investment with finding a return on investment. In an overview of energy consumption study, a sample beverage factory uses electrical energy and thermal energy derived from fuel. The proportion of electricity consumption is 24.83%, The thermal energy consumption from the fuel is 75.17%. Process in the supporting section used energy 86.88% of total energy consumption. The implementation cost reduction non-investment can reduce energy costs by 979,471.13 baht per year. Implementing cost reduction with an investment of 7,937,334.50 baht can reduce energy costs by 5,586,093.06 baht per year and has a payback period of 1.42 years. They both implement can reduce energy costs by 6,565,564.19 baht per year and has a payback period of 1.21 years. Chiller high-efficiency can also reduce energy costs and support the demand for Chilled water at the maximum volume of the process. The overall implementation results can reduce Specific Energy Consumption by 9.59 and reduce the cost of Specific Energy Consumption by 3.52%
