FAQ
Vaccine storage is all about Strive for Five, right? Well, is this the perfect vaccine fridge? It’s certainly one of the most consistent we’ve seen.
The average temperature is bang on 5° and the variation between the min and max temperatures is an incredible 0.5°.
This fridge is much more typical. Still nicely averaging close to 5° but with a min-max variation closer to 2°.
If your Clever Logger graph looks like this, you should be happy with your vaccine fridge.
This graph close-up show how fridges work. The temperature in the fridge cabinet slowly rises as warmth from the outside raises the temperature of the air in the fridge.
When it reaches a certain temperature, a sensor turns the fridge’s compressor on and the temperature in the fridge starts to fall.
When the low temperature is reached, the compressor switches off. The temperature begins to rise and the cycle repeats.
This is something we see a lot in food fridges and freezers, but not generally in vaccine fridges – a defrost cycle. The regular spikes in temperature are the fridge warming up to prevent icing up.
We couldn’t figure out why this was showing up on the graph until the customer told us that they has stuck the logger to wall of the fridge with double sided tape. This is a no-no as the logger then tends to measure the temperature of the cabinet wall rather than the air temperature.
When the power goes out, we see the temperature slowly rise. Then, when the power comes back on, the temperature rapidly falls back into range.
This poor fridge is really struggling – it is low on refrigerant gas. When the compressor kicks in, the lack of refrigerant means the fridge can’t produce very cold air and must run for a really long time to lower the temperature.
This compressor is running flat-out constantly for hours and hours at a time. Imagine the electricity bill!
Here’s the opposite problem – a fridge that cooled things down too well.
In this fridge, the sensor that was meant to switch the compressor off at a certain temperature failed and the fridge kept running until the temperature reached a staggering -16°. Of course, everything in the fridge was frozen solid.
When your Clever Logger starts letting you know about problems, it’s important to act.
In our last example, we see a fridge that was going along beautifully when it began to fail.
When you see anything out of the ordinary, contact your fridge technician immediately and get them to come and take a look.
