Eli5, Why the lowest (coldest) an Air Conditioner is able to set to, is 16 celcius?

146 viewsEngineeringOther

As the title says, why is that the case? (16 Celsius ~ 60 Fahrenheit)

I’ve read somewhere, that 16c is suppose to be the most efficient / comfortable?

Prob need an AC techie here, but I’ve experienced being in my car during summer & have to hit the “max” button on those really hot days, & it automatically goes straight to high fan setting + 16 celcius.

How come it doesn’t go futher? Like 12 or 10 Celsius?

& I’ve also experienced my home AC, where I’ve set it to 23 celcius, but a larger horsepower (4 or 5hp) & it’s freezing!

Thanks, for the insight 😊

Little tip: when you get in your car on a hot day, don’t set your AC to max and let it blast. Yes it will cool down your car and it will blow hot and then cooler air while it does so but it also works overtime. Set your AC to 2-3 degrees Celsius (I don’t know how to convert that to Fahrenheit) lower than the outside temperature.

It’s not as taxing on your AC and achieves the same result.
