AI Technical Summary

Technical Problem

The cooling performance of roof-mounted parking air conditioners decreases during vehicle operation due to wind resistance, a problem that is difficult to effectively solve with existing technologies.

Method used

By acquiring identification information when the vehicle speed is not zero and the wind speed is greater than a threshold, the direction and speed of the outdoor fan blades of the parking air conditioner are controlled to maximize the driving force of the wind on the air conditioner, or the wind energy is converted into electrical energy and stored in the vehicle battery to reduce the energy consumption of the motor drive.

Benefits of technology

While ensuring cooling performance, energy consumption was reduced, the impact of wind resistance on the performance of roof-mounted parking air conditioners was resolved, and energy-saving effects were achieved.

Abstract

This application provides an energy-saving control method, device, and parking air conditioner for a roof-mounted parking air conditioner. The method includes: when the current vehicle speed is not zero and the current wind speed is greater than a first threshold, acquiring identification information, where the current wind speed is the oncoming wind speed of the parking air conditioner's external fan, and the identification information indicates whether the parking air conditioner is on or off; when the identification information indicates that the parking air conditioner is on, switching the parking air conditioner to a first driving mode, whereby the fan blades of the parking air conditioner's external fan are controlled to run in a target direction and the fan blade rotation speed is adjusted to maximize the driving force generated by the wind on the parking air conditioner, and the target direction is the same as the airflow direction generated by the pressure difference between the air inlet and outlet of the air conditioner's external fan. This method solves the problem in the prior art where the performance of a roof-mounted parking air conditioner degrades during driving due to the resistance generated by the wind on the external fan.
