Standard Target
Maintenance and check Others Improvement of equipment and installation of energy conservation equipment
"Control standard" shall be established to periodically maintain and check combustion equipment. When combustion equipment is newly installed, a combustor capable of adjusting the amount of fuel supplied and the air ratio shall be introduced. Efforts shall be made to lower the air ratio to "desired value".
It shall be examined to install a combustion controller.
It shall be examined to convert existing combustion equipment into combustors capable of adjusting the amount of fuel supplied and the air ratio.
"Control standard" shall be established to periodically maintain and check equipment such as boilers.
"Control standard" shall be established to periodically maintain and check air conditioners.		 When heating equipment is newly installed, measures such as using the materials having high thermal conductivity shall be taken.
When air-conditioning equipment is newly installed, measures such as the separate control of the sections to be air conditioned shall be taken.		 The target shall be to reduce the temperature at the inlet of the cooler or condenser to less than 200degree Celsius and efforts shall be made to recover heat as efficiently as possible.
The forms of industrial furnaces, etc. shall be examined for improving the emissivity.
It shall be examined to improve the heat insulation of industrial furnaces to "desired value".
For heating equipment such as boilers, it shall be examined to adopt equipment higher in thermal efficiency.
For air conditioning, it shall be examined to adopt equipment high in thermal efficiency such as heat pumps.
"Control standard" shall be established to periodically maintain and check for prevention of heat dissipation, etc. When heat utilizing equipment is newly installed, measures such as doubling the heat insulation shall be taken.
"Control standard" shall be established to periodically maintain and check waste heat recovery equipment. When waste heat recovery equipment is newly installed, measures such as intensifying heat insulation shall be taken. Efforts shall be made to raise the waste heat recovery rate to "desired value".
"Control standard" shall be established to periodically maintain and check the combined heat and power generation equipment. When power generation equipment or cogeneration equipment is newly installed, the capacity of the equipment shall be on a proper level. The possibility of installing cogeneration equipment shall be studied if there is a great demand for steam or hot water.
Remodeling of turbine shall be examined, if there is possibility of enhancing its efficiency.
When a totally-enclosed motor having an output of 0.2 to 37kW and a high efficiency is adopted, efforts shall be made to realize an efficiency higher than the "target value".
It shall be examined to keep the power factor at 95% or more at the receiving end.
For electric power applying equipment, it shall be examined to install a rotational speed controller.
Efforts shall be made to adopt high efficiency lighting appliances, such as Hf fluorescent lamps and HID lamps.
"Control standard" shall be established to periodically maintain and check the receiving and transforming equipment, etc. When a transformer is newly installed, its actual and future demand for electric power shall be examined to determine the voltage of power distributed and the capacity of the transformer.
"Control standard" shall be established to periodically maintain and check the electric power applying equipment.
"Control standard" shall be established to clean the lighting system occasionally.		 When power using equipment is newly installed, its structure shall be the one easy to adjust the operational conditions.
When lighting equipment is newly installed, considerations shall be given to adopt an energy-saving type.
It shall be examined to effectively utilize the surplus factory steam, etc. inside or outside the factory.
