ENERGY CONSERVATION IN LIGHTING AND COOLING SYSTEMS IN THE FROZEN SEAFOOD PRODUCTION PROCESS. CASE STUDY: FROZEN FOOD PRODUCTION AND SELLS COMPANY IN NADEE DISTRICT, SAMUTH SAKORN PROVINCE

Abstract

The purpose of this research is to study the appropriate methods for reducing energy consumption in the Frozen Seafood production process by analyzing the energy used in the process with the appropriate measures. Due to in the past, the case study company used a lot of electric energy in lighting and cooling systems in its Frozen Warehouse. From studying found that the total energy consumption in lighting and cooling systems is as high as 338,109.74 KWh/year, with an electric energy cost of 1,254,387.13 baht/year. It accounts for 61.87% of electric energy consumption. Therefore, we have analyzed the measures to reduce energy consumption in order to reduce costs in the process which there are many measures can be used but two main measures have been chosen namely the measure to reduce the amount of unnecessary light by changing to LED with high lighting efficiency and low electricity consumption and also environmentally friendly and another one measure is to increase the cooling temperature from the original too low setting. By using comparative analysis and economic evaluation methods, the amount of electricity used in lighting and cooling systems in Frozen Warehouses can be reduced by 96,797.92 KWh/year and electric energy cost of 379,045.34 baht/year or a reduction of 30.22% with a payback period of 5 months.
