Evaporator temperatures below 32° are common and acceptable in refrigeration; that's why there is a defrost sequence. In a heat pump running in heat mode, it's the same; freezing is a part of the process, and defrost is necessary. In comfort cooling, we can't allow the evaporator to get below 32°, or it will freeze.

Before the fighting starts about term definitions, let's just settle on using “adjustable drive pulley” and “sheave” interchangeably to describe the belt-driven power transmission device shown above. Second, for the newer tech, you shouldn't be altering these sheaves so that the belt rides lower or higher in them unless you know EXACTLY what you are […]

A little precision to Q.2: The water boils at 100 degrees Celcius (but only at sea level!). The boiling point of water decreases with elevation comparing to sea level. Most parts in Florida are nearly at sea level. But, for example, at Denver, Colorado (the city is located 5,414 ft above sea level) the boiling point of water is around 94.6 degrees Celcius (202 degrees Fahrenheit).

Didn’t think of that one.

I think the correct answer is 288000 not 280,000 on BTU’S per ton Question 144btu per lb times 2000 = 288000?
unless I missed something
