Economizer Air Intake Control Using Climate Zone Auto-Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioning economizer systems require manual determination of shut-off control settings based on specific climate zones, leading to potential energy waste and incorrect setup, especially in moist climates where improper settings can result in reduced energy savings and unhealthy indoor conditions.
Innovation Solution
A control device and method that automatically determine the shut-off control setting for outdoor air intake by using a location determination module to identify the geographical location and a configuration module to define the shut-off control setting based on the associated climate zone, eliminating the need for personnel to manually select settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual determination of shut-off control settings is used, then personnel can select settings based on local knowledge, but this leads to potential energy waste and incorrect setup due to human error
Solution Approach 1:
The control device automatically determines the shut-off control setting based on geographical location data without requiring manual configuration by personnel. The system self-configures by receiving location data, identifying the climate zone, and automatically setting the appropriate shut-off temperature from stored climate zone data, eliminating human error in manual setup.
Solution Approach 2:
Climate zone data including shut-off control settings for different geographical locations is pre-stored in the control device. When the device receives geographical location data, it can immediately retrieve and apply the appropriate pre-determined setting without requiring real-time calculation or manual input, enabling fast automatic configuration.
2Loss of energy
If automatic reduction of outdoor air intake is implemented, then energy efficiency is improved, but the system requires complex control logic to determine when to reduce intake
Solution Approach 1:
The control device continuously monitors outdoor air quality parameters (temperature, humidity, dew point) and compares them against the pre-stored climate zone thresholds. When outdoor conditions exceed the shut-off control setting, the system automatically reduces outdoor air intake to the design minimum quantity, providing continuous feedback-based energy optimization.
Solution Approach 2:
The system changes operational parameters (outdoor air intake quantity) based on measured environmental parameters (temperature, humidity, dew point) compared against climate zone-specific thresholds. This allows automatic adaptation to varying outdoor conditions while maintaining simple control logic based on pre-determined parameter limits.
3Use of energy by moving object
If climate zone-specific settings are used, then energy efficiency is optimized for local conditions, but installing personnel must manually determine the correct climate zone setting
Solution Approach 1:
The control device automatically determines the appropriate climate zone setting by receiving geographical location data and identifying the corresponding climate zone from pre-stored data. This eliminates the need for installing personnel to manually determine climate zones or configure settings, while still achieving optimized energy efficiency for local conditions.
Solution Approach 2:
The control device is designed to work universally across different climate zones by pre-storing climate zone data for multiple geographical regions. The same device can be deployed anywhere, and it automatically adapts to the local climate zone based on geographical location data, eliminating the need for different device configurations or models for different regions.

AI summary
In an air conditioning economizer system outdoor air intake is reduced automatically by a control device based on a shut-off control setting for a measured outdoor air quality. A geographical location associated with the air conditioning economizer system is received (S2) in the control device. The control device defines automatically (S3) the shut-off control setting based on the geographical location. Thus, the air conditioning economizer system is adapted specifically for a geographic location and its climate zone, without the requirement for installing or operating personnel to determine a shut-off control setting for a specific climate zone and/or select a corresponding operating range.
