ELPRO Lepenik is a family-run business with a professional staff focused on solving challenges.
If we’re wondering, it’s certainly interesting for others, so we measured the temperature in our parked cars. Of course, the measurements were carried out in accordance with professional guidelines.
We chased the heatwave roaring out of our parked cars on a hot Tuesday in July under the guidance of a meteorologist.
We measured the temperature inside our cars while they were parked in the company car park. The measurements were combined with additional factors that affect the temperature results – some cars were dark, others were light, or had windows open or closed.
In the morning, the Metrologist installed temperature monitors, EBI 20 data loggers, in cars and in the surrounding open air at selected checkpoints. Everything was in place to monitor the temperature inside our steel hobby.
On this day, temperatures were truly reaching record highs. In the sun, ambient conditions reached up to 51 °C.
The accredited laboratory has delivered the official results we expected.
The difference in the colour of your car – black or white – will change the temperature inside your car by almost 12 °C when the windows are closed and by less than 3 °C when the windows are open.
Open windows make a big contribution to more bearable temperatures, namely 9-10 °C.
The best conditions when going home were for a colleague who parked under the carport and had the windows open. Expected, but not all of us are so lucky. Most of us park under a blue sky.
We have noticed some interesting factors, so we will repeat the measurement at another time. It would be interesting to see the use of shading and its impact, and for example surface measurements at different points in the car. We can confirm that attention and ventilation are a MUST before getting into an overheated car. It is also a good idea not to leave electronic devices in the car, as these temperatures can quickly become too high for many of them.
