Part 4/8:
When switched on, the Peltier fridge emits significant noise, attributed to a fan system required to dissipate heat generated by the device. While the cooling side can absorb heat, the hot side easily reaches problematic temperatures, necessitating additional mechanisms to manage heat dissipation.
Notably, the typical performance charts show a stark reality: even after lengthy periods of cooling, internal temperatures remain high, often surpassing what would be deemed acceptable for food safety standards. Testing over two dozen hours demonstrated only a slight drop in temperature, further solidifying the notion that these devices are not suitable substitutes for conventional refrigeration systems.
