Air-conditioning system, air-conditioning control method, and air-conditioning control program
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air-conditioning systems for vehicles with cold storage fail to effectively notify temperature errors in various situations, such as when the luggage compartment door is open or when temperature abnormalities are anticipated during loading and unloading.
Innovation Solution
An air-conditioning system that includes an air conditioner mounted on a mobile body with a cold storage, an internal temperature sensor, a notification device, and a control unit. The control unit acquires internal temperature data, sets an appropriate temperature range, determines if the temperature is within this range, and controls error notifications. It performs temperature error notifications only after pre-cooling is completed and the temperature is out of the appropriate range, avoiding unnecessary notifications during pre-cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If temperature error notification is performed continuously, then users are informed of all temperature deviations, but unnecessary alerts are generated during pre-cooling when temperature deviations are expected
Solution Approach 1:
The system performs pre-cooling as a preliminary action before normal operation, during which temperature deviations are expected and acceptable. The notification control unit is designed to recognize this preliminary phase and suppress error notifications during this period, thereby avoiding unnecessary alerts while maintaining reliable notification capability for actual errors that occur after pre-cooling completes
Solution Approach 2:
The notification control unit dynamically adjusts its behavior based on the operational phase of the air conditioner. It transitions from a suppressed notification state during pre-cooling to an active notification state after pre-cooling completes, allowing the system to adapt its notification behavior to current operational conditions and avoid generating harmful unnecessary alerts
2Measurement precision
If temperature monitoring is performed during pre-cooling, then temperature deviations are detected, but false error alarms are triggered since deviations are normal during this phase
Solution Approach 1:
The system recognizes pre-cooling as a preliminary operational phase where temperature deviations are normal and expected. The notification control unit uses this recognition to filter out false error alarms during this phase, preserving the useful error notification signal for actual problems that occur during normal operation after pre-cooling completes

AI summary
An air-conditioning system includes: an air conditioner mounted on a mobile body having a cold storage; an internal temperature sensor configured to measure an internal temperature inside the cold storage; a notification device configured to notify an error of the air conditioner; and a control unit configured to control an air-conditioning operation. The control unit includes an acquisition unit configured to acquire the internal temperature, a setting unit configured to set an appropriate temperature range of the cold storage, a determination unit configured to determine whether the internal temperature is within the appropriate temperature range, and a notification control unit configured to control an error notification using the notification device and perform a temperature error notification when the internal temperature is out of the appropriate temperature range after a pre-cooling by the air conditioner is completed, and does not perform the temperature error notification before the pre-cooling is completed.
