Relationship between C.O.P. and outside air temperature

AI Thread Summary
The efficiency of an air conditioner, indicated by its Coefficient of Performance (C.O.P.), is influenced by outside air temperature, particularly the condenser's location. Placing the condenser in shaded areas can enhance efficiency by lowering its temperature, which in turn improves the C.O.P. The formula COPmax = Te/(Tc-Te) illustrates that maximum efficiency is achieved when the evaporator temperature is significantly lower than the condenser temperature. While the unit's casing may provide some shading, it is generally not sufficient to negate the benefits of additional shading. Therefore, positioning the condenser in a cooler, shaded environment can lead to greater overall efficiency.

Since the capacity of an air conditioner is a function of outside air temperature, does it follow that greater efficiency will be achieved by putting the condenser under shade rather than out in the open or on a hot roof? Or does the casing of the unit provide adequate shading to make this difference negligible?
 
Engineering news on Phys.org
COPmax = Te/(Tc-Te)
This is the maximum achievable COP.
Te is evaporator temperature
Tc is condenser temperature
Generally, Te = Trequired - 10
Tc = Tambient + 10
Yes ! it will
 
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...
