Will this increase the Coefficient of performance of my refrigerator?

AI Thread Summary
Orienting a refrigerator with its condenser coils facing a glass door can increase its Coefficient of Performance (CP) by reducing the temperature difference between the condenser and the environment, thus enhancing efficiency. This setup is unlikely to cause damage to the refrigerator and may even extend the compressor's lifespan due to reduced operational strain. While the refrigerator contributes to heating in winter, making it cost-effective, the glass door orientation is particularly beneficial in summer, especially when using air conditioning. However, this arrangement could obstruct access to the door. Overall, the approach improves efficiency without negative consequences.

If I orient my refrigerator such that the condenser coils at the back are facing a glass door (least insulation in room, cold outdoors) will CP increase? CP=Qc/(Qh-Qc) so Qh-Qc will be smaller thus CP larger. Could this damage refrigerator?

Yes it would increase the efficiency, no it wouldn't cause damage. But it would block the door.

Better than that; the compressor will last longer because it won't be running quite so much.
However, every Joule of energy that you put into the fridge turns up as some extra heating for the house. In winter, the fridge is doing its bit and largely costs nothing to run (if you care to look at it that way). In summer, your glass door trick could be of benefit, particularly if you use A/C.
 
Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...
TL;DR Summary: Heard in the news about using sonar to locate the sub Hello : After the sinking of the ship near the Greek shores , carrying of alot of people , there was another accident that include 5 tourists and a submarine visiting the titanic , which went missing Some technical notes captured my attention, that there us few sonar devices are hearing sounds repeated every 30 seconds , but they are not able to locate the source Is it possible that the sound waves are reflecting from...
Thread 'Turbocharging carbureted petrol 2 stroke engines'
Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
