Explanation:

Answer:

1. Subcooling takes place in the condenser. Super - heat takes place in the evaporator and suction line.
2. In the condenser.
3. In the evaporator and suction line.
4. Subcooling is the process of cooling a liquid below its saturation temperature at a given pressure.
5. Superheat is the heat added to a vapor above its saturation temperature at a given pressure.
6. Subcooling tells the technician about the amount of liquid refrigerant leaving the condenser and can indicate issues like refrigerant charge, condenser performance, and system restrictions.
7. Superheat tells the technician about the amount of vaporization in the evaporator, refrigerant flow, and can help diagnose problems such as low refrigerant charge or restricted metering devices.
8. For subcooling, at the liquid line near the condenser outlet. For superheat, 10 - 12 inches from the compressor on the suction line.
9. Temperature.
10. Use a pressure - temperature (P/T) chart.
11. A P/T chart tells you the saturation temperature corresponding to a given pressure for a particular refrigerant.
12. Checking subcooling/superheat tells you about the refrigerant charge, system performance, and can help diagnose issues such as restricted components, inefficient heat transfer, or problems with the metering device.
