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.
 

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
