This is because most of the action is to optimize the device. Power on the system, Cook and cooling system, lighting system, the cost of the measures is quite low.
This is due mainly to the measures taken to optimize the device. Energy in LNG Cooling System And lighting systems, making it a relatively low cost of the measures taken.
However, due to the measures mainly to enhance energy supplies in ระบบหุงต้ม evaporative cooling system. Lighting system and the cost of the measures was relatively low.
