16.1 Refrigeration cycle system
In order to diagnose malfunctions, ensure the air conditioner is free
from electrical problems before inspecting the refrigeration cycle.
Such problems include insufficient insulation, problem with the
power source, malfunction of a compressor and a fan. The normal
outlet air temperature and pressure of the refrigeration cycle
depends on various conditions, the standard values for them are
shown in the table to the right.
