Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air conditioning systems for vehicles and buildings operate independently, leading to inefficiencies in energy usage and lack of integrated control when a vehicle is docked to a building, failing to optimize energy management and air conditioning performance across connected spaces.
Innovation Solution
A vehicle and building integrated air conditioning system that allows fluidic communication between internal spaces when docked, featuring a control unit to manage both vehicle and building air conditioning devices, enabling dual or single mode operation based on temperature differences and selecting air circulation modes to optimize energy use, with the option for one unit to act as a master for integrated control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vehicle and building air conditioning systems operate independently, then each system can be controlled separately, but energy usage efficiency deteriorates and integrated control is lost
Solution Approach 1:
The patent merges the vehicle air conditioning system and building air conditioning system into a unified integrated control architecture. When the vehicle is docked at the building, the integrated control unit coordinates both systems to share thermal loads, allowing the vehicle AC to supplement building cooling or heating needs, thereby improving overall energy efficiency while maintaining independent control capabilities when docked
2Device complexity
If vehicle and building air conditioning systems operate independently, then system complexity is reduced, but integrated control and energy optimization are lost
Solution Approach 1:
The integrated control unit serves multiple functions: it controls the vehicle air conditioning system, controls the building air conditioning system, manages battery charging, and coordinates thermal sharing between vehicle and building. This multi-functional controller enables energy optimization across both systems without requiring separate complex control architectures for each function
3Use of energy by moving object
If integrated control is implemented when vehicle is docked, then energy management is optimized, but control system complexity increases
Solution Approach 1:
The integrated control unit acts as an intermediary between the vehicle control unit and building control unit. It receives operational status and thermal requirements from both systems, makes coordination decisions based on energy optimization goals, and sends control commands accordingly. This intermediary approach enables energy management optimization without requiring direct complex interactions between the vehicle and building control systems
4Measurement precision
If dual mode air conditioning operation is used, then temperature control precision is improved, but energy consumption increases
Solution Approach 1:
The integrated control unit implements partial action by selectively activating air conditioning in either the vehicle, the building, or both simultaneously based on the degree of temperature deviation from setpoints. When temperature differences are small, only one system operates; when differences are large, both systems operate to achieve faster and more precise temperature control, thereby balancing precision requirements with energy conservation

This system efficiently manages air conditioning across connected vehicle and building spaces, reducing energy consumption by optimizing temperature control and air circulation, and allows battery charging from the building's power supply when necessary, enhancing energy utilization and comfort.
Implementation Method 1
fluidically communicates an interior of the building with the vehicle to perform the air conditioning when the vehicle is docked to the station
Implementation Method 2
control so that the air conditioning is executed in a dual mode in which the vehicle air conditioning device and the building air conditioning device are simultaneously operated if differences between the target temperatures and current temperatures are set values or more
Implementation Method 3
control to charge the battery when a charge state of the battery is equal to or less than a predetermined value
