Integrated system of vehicle air conditioning and cooling or heating device, and control method thereof

An integrated system of vehicle air conditioning and a cooling or heating device, comprising:

• a primary ventilation system, the primary ventilation system comprising an air intake duct, a heating, ventilation, and air conditioning (HVAC) system, and an air supply duct;
• and
• a cooling or heating device;
• wherein:
• the air intake duct comprises a fresh air inlet and a recirculated air inlet;
• an outlet of the air intake duct is connected to the HVAC system;
• the HVAC system comprises a high-power air supply fan and a heat exchanger;
• an outlet of the HVAC system is connected to the air supply duct, and an end of the air supply duct is provided with a plurality of air outlet ducts;
• a plurality of end air supply systems are respectively disposed at openings of the plurality of air outlet ducts;
• each of the end air supply systems comprises a low-power air supply fan and a low-speed fan;
• the low-power air supply fan is disposed at one end of a corresponding air outlet duct, and the low-speed fan is disposed beside an opening of the air outlet duct;
• the end air supply systems are configured to mix a low/high-temperature airflow output by the HVAC system with an ambient indoor airflow and direct mixed air to passengers in a passenger compartment;
• and
• the cooling or heating device comprises a plurality of end pipes disposed at the end of the air supply duct;
• a cooling fan is disposed inside each end pipe;
• the cooling fan uses the low/high-temperature airflow output by the HVAC system to dissipate heat from or heat a vehicle’s power battery and/or drive control system.
