IN-VEHICLE AIR CONDITIONER - A simplified explanation of the abstract

This abstract first appeared for US patent application 18625203 titled 'IN-VEHICLE AIR CONDITIONER

The abstract describes an in-vehicle air conditioner that includes a blower, a cooling device with a heat exchanger, and a controller to control the blower and cooling device. The controller can operate the blower to perform pre-air-conditioning by introducing outside air into the vehicle compartment while the cooling device is stopped, when the in-vehicle battery is being charged and no occupant is present.

  • The controller increases the blower output during a predetermined period if the cooling device was operating before the ignition switch is turned off.
  • This pre-air-conditioning process helps maintain a comfortable temperature in the vehicle without using the cooling device, saving energy.
  • The system is designed to optimize energy usage and provide a comfortable environment for occupants.

Potential Applications: - Automotive industry for improving energy efficiency in vehicles. - Climate control systems in electric vehicles. - Smart energy management systems for vehicles.

Problems Solved: - Energy consumption optimization in vehicle air conditioning systems. - Providing comfort without excessive energy usage. - Enhancing the efficiency of in-vehicle climate control.

Benefits: - Energy savings. - Improved comfort for occupants. - Enhanced environmental sustainability.

Commercial Applications: "Energy-Efficient Pre-Air-Conditioning System for Vehicles: Market Implications and Potential Uses"

Questions about the technology: 1. How does the pre-air-conditioning process help in optimizing energy usage? 2. What are the potential long-term benefits of implementing this technology in vehicles?


Original Abstract Submitted

An in-vehicle air conditioner includes a blower configured to send blown air to a vehicle compartment, a cooling device having a heat exchanger for cooling the blown air, and a controller configured to control the blower and the cooling device. The controller operates the blower to perform a simplified pre-air-conditioning for introducing outside air into the vehicle compartment while the cooling device is stopped, in a case where an in-vehicle battery is being charged by an external power supply and no occupant is present in the vehicle compartment. In the simplified pre-air-conditioning, the controller increases output of the blower during a predetermined period of time in a case where the cooling device has been operating immediately before an ignition switch is turned off, so as to be greater as compared to a case where the cooling device has not being operating immediately before the ignition switch is turned off.
