By operating it properly, the heat load can be reduced and the thermal stress on the equipment inside the panel can be alleviated, leading to stable operation of the equipment.
Introducing heat problems in panel and key operational and energy-saving tips!
This book focuses on heat problems in panel, and provides information on the basics of heat problems, as well as a summary of some key points that can lead to efficient operation and energy conservation of panel.
Reduce heat load (heat intrusion)
Location
- Choose a well-ventilated location.
- Do not install near large heat sources such as heating furnaces/drying ovens.
panel Avoid locations where there is a sunny window in the rear or over a slate wall with poor insulation.
- Choose a location that is not exposed to direct sunlight from a skylight.
Do not install in a remote location in the room.
Heat shielding measures
- Install heat shields in places where there is a lot of radiant heat, such as near a furnace.
- When using control panel cooling unit, if you are installing it in parallel or facing each other, install it in a location where it will not be exposed to or absorb the exhaust heat from the adjacent cooler.
- When installing control panel cooling unit in parallel, install a heat shield between adjacent cooler.
Insulation method
Apply the insulation material to the inside of the panel. If you are insulating the back, apply it to the surface.
Increase heat dissipation efficiency inside the panel
- Install an internal circulation fan to increase circulation efficiency within the panel.
When using control panel cooling unit, set the in-board circulation fan to continuous operation.
Increase the efficiency of intake and exhaust within the panel
- If the surrounding temperature is high, send cooler air, such as fresh air, to the intake port on the heat dissipation side.
Quick explanation: How to select products that will increase energy-saving effects
If you choose a type with a high cooling capacity relative to the heat load, the operating rate will be lower and power consumption will be reduced.
In particular, inverter types have a tremendous energy-saving effect when the thermal load rate is reduced by controlling the rotation speed.
