That makes sense. I was completely focused on only the device.

While they both interchange heat, the principle of evaporators and radiators is different.

The condenser and the evaporator are both evaporators

Did you add that to prove yourself wrong?

There’s no radiator, it’s a heat exchanger.

You have two sections in your heat exchanger. One part wants the cooling agent cold so it can effectively imterchange heat from your room into the cooling liquid. The other part wants the cooling agent hotter than the air outside so it can effectively dissipate the heat to the outside. To achieve that the liquid gets compressed. On the cold side it gets cooled with airflow.

I don’t think sunlight will change anything significant in that mechanism.

I doubt it will make it more efficient. The air it sucks in is still the same temperature.

It might help with longevity of the device itself though, as it doesn’t stand in direct sunlight.

Birthday is just another day in the year. It doesn’t matter when you treat yourself as if it’s your birthday, because you should do that more often anyways, like once every month, if missing that one day in the year stresses you out that much.

It obviously sucks to have your plans ruined läßt minute. I didn’t intend to downplay the value of such a day or discredit your feelings.
