Abstract

A cooling device and a controlling method thereof for a reefer container are disclosed. The cooling device has a controlling circuit comprising a controller (4); a compressor relay (1), a condenser fan relay (2) and an evaporator fan relay (3) connected in parallel; a pressure switch (7) connected to the compressor relay (1) in series; and a pressure sensing and controlling device for controlling the pressure switch (7) to turn on or off. The pressure sensing and controlling device controls the pressure switch (7) to turn off when air pressure inside container drops to a preset pressure, and controls the pressure switch (7) to turn on when air pressure inside container rises higher than the preset pressure. The controlling method comprises steps of detecting and controlling air pressure inside container. The invention can be implemented in a simple structure and at a low cost, as only a few of electric elements are added to conventional controlling circuits.
