[0043] The evaporator 1431 is filled with a refrigerant. The compressor 141 compresses the refrigerant into a high-temperature and high-pressure gas. The high-temperature and high-pressure gas dissipates heat through the condenser 142 and becomes a high-pressure liquid. The high-pressure liquid passes through the throttle of the expansion valve 1445 and becomes a low-pressure liquid. The low-pressure liquid absorbs the heat in the air-conditioning main unit 143 when passing through the evaporator 1431. The temperature in the air-conditioning main unit 143 decreases. The cold air in the air-conditioning main unit 143 is directly discharged into the passenger compartment 101 through the first air outlet 1221 and the second air outlet 1211 to cool the passenger compartment 101. After passing through the evaporator 1431, the low-pressure liquid becomes a low-temperature and low-pressure gas. The low-temperature and low-pressure gas enters the compressor 141 again to form a cycle, realizing continuous refrigeration of the passenger compartment 101.

[0044] Regarding "component A and component B are connected", it means that component A is directly connected to component B, or component A is indirectly connected to component B through an intermediate component C.
