Common outdoor unit insulation/heat release/cooling device issues
The failure rate and life of electric/control and broadcast devices are strongly affected by heat around.
【Douser】
●When a heating element is present, heat builds up
●Once heat builds up, it’s hard for internal temperature to drop
【Cooling fans】
●For air intake Sucks in dust, humidity
●Regular maintenance is necessary
【Panel coolers】
●Needs electricity
Introduction example and effect of high voltage receiving and transforming switchboard
Air conditioning power consumption is reduced by approximately 21% on sunny days and by approximately 20% over the entire period, including rainy and cloudy days.
<Test conditions>
Test date： Measured the power consumption reduction effect over the entire period from July 22nd to August 31st before construction and from September 1st after construction.
Installation location：SPACECOOL is installed on the roof, east, west, south, and north walls.
Internal storage equipment：Vacuum circuit breaker 3.6kV 600A x 6 units
Molded transformer 3Φ3.3kV/210V 100kVA x 1 unit
Molded transformer 1Φ3.3kV/210-105V 100kVA x 1 unit
DC power supply 2.6kVA x 1, storage battery MSE 50Ah @ 10 hour rate 54 cells (MSE-50-12 x 9, DC108V/set)
Air conditioner capacity 1Φ100V 615W×3
＜Test results＞
As a result of monitoring air conditioning power consumption with and without this material, it was confirmed that air conditioning power consumption was reduced by approximately 21% on sunny days and by approximately 20% over the entire period, including rainy and cloudy days.
This demonstration experiment was carried out jointly with ENEOS Holdings Co., Ltd. with the aim of saving energy in high-voltage receiving and transforming boards (with air conditioning functions).
Examples of introducing electronic control panels and their effects
Reduces the temperature inside the electronic control panel by approximately -10°C
<Test conditions>
Test date：9/21/2021
Internal heat source：Device modeled after an inverter (200W)
Size：H1000/W600/D300
<Test results>
No heating element：Roughly 10℃ cooler than regular paint, Confirmed to be 5℃ cooler than douser.
Heating element present：Roughly 10℃ cooler than ordinary paint, Roughly 8℃ cooler than douser.
This demonstration was performed jointly with Takenaka Corporation and Seiritsu Kogyo as the Yumeshima demonstration.
*Yumeshima demonstration: Jointly sponsored by Osaka Chamber of Commerce and Industry and Japan Association for the 2025 World Exposition.
