16.1 Refrigeration cycle system
In order to diagnose malfunctions, make sure that there are no
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 on the right.
