That is, such that the inner space of the refrigerating cabinet 110 is partitioned into two separate spaces. And the two air exchange chambers are communicated with each other through the refrigeration module 130. That is, the gas enters the first air exchange chamber 111, is cooled by the cooling module 130, and then enters the second air exchange chamber 112. Thus, when the air is ventilated by the ventilator of the parking air conditioner, the air in the cab enters the first ventilation chamber 111 of the cooling box 110 through the air inlet duct 201, and is cooled by the cooling module 130 to become low-temperature gas. And flows into the second airing chamber 112 through the refrigeration module 130. Since the ventilation fan 120 is located in the second ventilation chamber 112, the low-temperature gas is returned to the cab from the air outlet duct 202 by the action of the ventilation fan 120, so as to cool the vehicle interior.

When ventilation is required, a pressure difference is formed between the inside and the outside of the cab by the ventilation fan 120, so that air in the external environment is sucked into a gap between the ventilation cover 300 and the intake cover through the ventilation holes 301 of the ventilation cover 300. The air flows to the ventilation unit 400 through the gap. At this time, the ventilation door 402 of the ventilation unit 400 is controlled to open, so that the air smoothly enters the air inlet duct 201, and then flows through the refrigeration unit 100 and the air outlet duct 202 in sequence, thereby realizing the ventilation process between the cab and the external environment.
