The Clever Design of a Simple Fridge

The fridge uses a split-evaporator design, with one section serving the fridge compartment and the other serving the freezer compartment.

The fridge has no fans, sensors, or automatic defrost heaters, making it a simple and cost-effective design.

The single thermostat is located in the fridge compartment, which means the freezer section doesn't react quickly to changes, and temperature gradients can occur.

The fridge has a small refrigeration circuit, which means a tiny leak can significantly affect its performance.

The fridge is suitable for storing frozen items, but not for rapidly freezing large quantities of food.

How does the split-evaporator design of the fridge work?

—The split-evaporator design uses a single refrigeration circuit with one section serving the fridge compartment and the other serving the freezer compartment. This design allows for two different temperatures to be maintained using a single thermostat.

Does the fridge have automatic defrost?

—No, the fridge does not have automatic defrost. Instead, it relies on the warm compressor to evaporate the melted water from the defrosting process.

What are the advantages of the fridge's minimalist design?

—The minimalist design of the fridge eliminates the need for fans, sensors, and automatic defrost heaters, making it a cost-effective and reliable option. It also has a simple and straightforward refrigeration circuit.

Are there any limitations to the fridge's design?

—The fridge's single thermostat located in the fridge compartment means that the freezer section doesn't react quickly to temperature changes. Additionally, the small refrigeration circuit can be affected by even a tiny refrigerant leak.

Is the fridge suitable for freezing large quantities of food?

—No, the fridge is not designed for rapidly freezing large quantities of food. It is more suitable for storing frozen items at a consistent temperature.
