Superheat and Subcool Flashcard 1.0

Front

What two temperatures are needed to find target super heat?

Back

Return air wet-bulb temperature and condenser ambient air dry-bulb temperature

Front

What is the formula for actual super heat?

Back

suction line temp. - compound gauge saturated temperature

Front

Saturated evaporator temperature

Back

The temperature at which a liquid becomes a gas (Vapor)

Front

Which line is the temperature taken from when checking for super heat?

Back

suction line with the system running and the refrigerant is in a low-pressure & temperature state.

Front

If your target super heat is 10 degrees but your calculations show 5, is the system undercharged or overcharged?

Back

Overcharged

Front

What kind of chart is used to convert the pressure reading used in finding super heat to a temperature?

Back

Pressure-temperature chart

Front

What is the formula for subcool?

Back

High-side gauge temperature - liquid line temperature

Front

Saturated condenser temperature means what and can be found where?

Back

The temperature at which a gas becomes a liquid.

Front

Which line is the line temp taken and what is the state of the refrigerant for subcool?

Back

The liquid line with system running and refrigerant at high-temperature & pressure liquid

Front

The subcooling target is 10 degrees and actual subcooling measured is 5 degrees. Is the system overcharged or undercharged?

Back

undercharged
