Dullsters
Inspired by the Dull Men’s Club.
1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of “discuss” rarely comply with this rule.
2. Original, Fresh, Meaningful Content.
3. Avoid repetitive topics.
4. This isn't an advice forum
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.
There are a number of content specific communities with subject matter experts who can help you.
Some other communities to consider before posting:
5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.
6. No hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.
7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with “So” - starting a post with pointless phrases, like “I hope this is allowed” or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

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.
By keeping the sun off it, that helps with keeping the equipment cool which the radiator is part of so there's less heat the fins have to dissipate no?
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 think it’ll have an effect. If you think of the cross section of the piping in the condenser (radiator in the outside unit shown in photo), you have heat trying to transfer from the fluid on the inside diameter, through the pipe wall, then to the air surrounding the outer diameter.
Heat has to flow from hot to cold, so ideally you have a gradient from hot to cold going from inside to outside.
But suppose the sun intensely heats that pipe wall and it ends up higher than either fluid on either side of it. Now you’ve got heat flowing from the wall to both inside and outside.
Not saying that ever happens, but every degree warmer that the pipe wall is, is a slow down in the heat transfer rate. Less of a gradient for the heat flow.
That makes sense. I was completely focused on only the device.
...I hate the be the one to tell you this but there are two radiators in a heat pump. The condenser and the evaporator are both evaporators.
While they both interchange heat, the principle of evaporators and radiators is different.
Did you add that to prove yourself wrong?
probably just a brain fart - they've both heat exchangers.
