Description

Technical Field

[0001] This invention belongs to the field of parking air conditioning heat dissipation technology, and relates to a parking air conditioning heat exchange duct structure and control method based on a vehicle trunk pressure relief valve. Background Technology

[0002] Currently, split-type parking air conditioners require external installation of the condenser, which necessitates altering the original vehicle structure. Integrated parking air conditioners, with the entire unit located inside the vehicle, require the condenser to dissipate heat through ducts and windows. However, poor sealing between the ducts and windows leads to air leaks and affects aesthetics, while also preventing condensate from draining outside. While parking window air conditioners isolate the condenser outside the vehicle via the window, solving the heat dissipation, sealing, and drainage issues, the entire unit needs to be moved during use and disassembly. Furthermore, because the condenser is outside the window, especially when moving the vehicle or partially moving parts of it, the equipment must be removed for cumbersome storage and handling. Summary of the Invention

[0003] Purpose of the invention: The purpose of this invention is to provide a parking air conditioning heat exchange duct structure based on the vehicle trunk pressure relief valve, which solves the problem that existing parking air conditioning condenser heat dissipation technology requires changes to the original appearance, structure and function of the vehicle, while maintaining the original vehicle pressure relief function.

[0004] Another objective of this invention is to provide a control method for a parking air conditioning heat exchange duct structure based on a vehicle trunk pressure relief valve.

[0005] The technical solution of the present invention is: a parking air conditioning heat exchange duct structure based on a vehicle trunk pressure relief valve, wherein the parking air conditioning heat exchange duct structure is arranged in the vehicle trunk and includes an external circulation parking air conditioning heat dissipation air intake module, a parking air conditioning heat dissipation air supply module, a parking air conditioning heat dissipation air exhaust module and a parking condenser that are connected to each other. The external circulation parking air conditioning cooling intake module is installed on one side of the vehicle's trunk and connected to the original vehicle's pressure relief valve. It includes a condensate drain copper pipe, an air inlet, and an air pre-cooling coil. A condensate drain nozzle is provided on the condensate drain copper pipe for opening the original vehicle pressure relief valve curtain. The air inlet is connected to the original vehicle pressure relief valve, and the air precooling coil is connected to the parking air conditioner condensate drain outlet.

[0006] Furthermore, the parking air conditioning cooling and air supply module is connected to the air inlet of the external circulation parking air conditioning cooling and air intake module and the parking condenser through an installed air duct.

[0007] Furthermore, one side of the duct is connected to the air inlet, and the other side is connected to the air inlet of the parking condenser through the duct section one.

[0008] Furthermore, an air supply valve is installed inside the air duct.

[0009] Furthermore, the air precooling coil is installed inside the air duct.

[0010] Furthermore, a pressure relief module is connected between the external circulation parking air conditioner cooling intake module and the parking air conditioner cooling supply module, and an internal circulation cooling intake module is connected between the other end of the parking air conditioner cooling supply module and the parking condenser. The pressure relief module includes a second air duct, one end of which is connected to the first air duct, and the other end is open. The internal circulation heat dissipation air intake module includes a third air duct, one end of which is connected to the first air duct, and the other end is open.

[0011] Furthermore, a pressure relief valve is installed inside the second air duct, and an internal circulation valve is installed inside the third air duct.

[0012] Furthermore, the parking air conditioning cooling and ventilation module is installed on the other side of the vehicle's trunk, including a duct four connecting to the parking condenser and an exhaust vent connecting to the original vehicle's pressure relief valve two.

[0013] Furthermore, one side of the duct four is connected to the exhaust vent, and the other side is connected to the air outlet of the parking condenser through the duct section two.

[0014] Furthermore, the control method for the parking air conditioning heat exchange duct based on the vehicle trunk pressure relief valve has the following operation steps: Step (1) Parking mode: Turn on the parking air conditioner → open the air supply valve, close the pressure relief valve, and close the internal circulation valve; Step (2) Door closing mode: Parking air conditioner on → air supply valve closed, pressure relief valve open, internal circulation valve open.

[0015] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: 1. It reuses the original vehicle pressure relief valve, requiring no drilling of the vehicle body, no damage to the original sheet metal, no need to install a split outdoor unit, and no risk of water leakage or corrosion; 2. It features an independent and sealed exhaust duct, which introduces outdoor air for heat exchange and exhaust, without affecting the interior temperature and improving the air conditioning cooling performance; 3. It enables dual-mode switching between parking mode and door-closed mode, while fully retaining the original vehicle's door-closed pressure relief function; 4. The air duct is located inside the trunk, eliminating any external protruding parts for the parking air conditioner, allowing it to still be used when temporarily moving the vehicle or driving; 5. It is compatible with all SUVs, pickup trucks, and passenger vehicles equipped with a trunk pressure relief valve, offering good modification versatility. Attached Figure Description
