Temperature:
Temperature refers to a method of measuring the energy level of a substance at a certain time. The temperature range is based on the freezing point and boiling point of water.
On the Celsius thermometer, the freezing point of water is zero degrees and the boiling point is 100 degrees.
On a Fahrenheit thermometer, the freezing point of water is 32 degrees and the boiling point is 212 degrees.
Altitude:
Measured vertically upwards from sea level, altitude is simply the height above sea level. Elevation is an important factor in compressor engineering, because the higher the altitude, the thinner the air becomes, and the lower the absolute pressure becomes.
Since the air at high altitude is relatively thin, the cooling effect of the motor is relatively poor, which makes the standard motor only limited to a certain altitude.
