Solution Overview
Problem
Existing air-conditioning control methods in multi-zone living spaces often result in unbalanced energy-saving control time spans, leading to significant temperature fluctuations and discomfort for occupants.
Innovation Solution
An air-conditioning control device that calculates and sets a balanced control order for multiple air-conditioners based on their distances, ensuring that energy-saving controls are distributed evenly across the space to reduce power consumption and temperature fluctuations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If energy-saving control is performed simultaneously on all air-conditioners, then power consumption is reduced, but temperature in the living room space sharply rises causing poor environmental comfort
Solution Approach 1:
The patent implements periodic energy-saving control by alternating the operation of multiple air-conditioners in cycles. Instead of simultaneous deactivation, air-conditioners are deactivated in sequence across different time periods, ensuring continuous temperature maintenance while achieving overall energy savings.
Solution Approach 2:
The living room space is divided into multiple zones, and energy-saving control is applied segmentally to different air-conditioners in different zones. This segmentation allows the system to maintain temperature in active zones while deactivating others, preventing sharp temperature rises.
2Loss of energy
If deactivation control is repeatedly performed in arranged order of zones, then energy-saving control is achieved, but time span for energy-saving control becomes unbalanced causing great temperature fluctuation
Solution Approach 1:
The patent applies different control strategies to different zones based on their specific characteristics and occupancy patterns. Each zone receives customized energy-saving control timing and duration, ensuring balanced temperature maintenance across all areas while achieving comprehensive energy savings.
Solution Approach 2:
The system monitors temperature conditions in real-time and adjusts the energy-saving control schedule dynamically. When temperature fluctuations are detected, the control algorithm modifies the deactivation timing and duration for subsequent cycles, maintaining temperature stability while preserving energy-saving benefits.

AI summary
An air-conditioning control device (4) controls a plurality of air-conditioners (indoor devices) disposed at different locations within a predetermined living room space. A data manager (40) stores location information (82) for each air-conditioner (indoor device). A distance calculator (51) calculates a distance between respective air-conditioners (indoor devices) based on the location information (82). A control order setter (52) sets, based on the distance between respective air-conditioners (indoor devices) calculated by the distance calculator (51), a control order of each air-conditioner (indoor device) on which energy-saving control is to be performed in such a way that time spans for performing the energy-saving control that controls respective air-conditioners (indoor devices) for a predetermined time to suppress power consumption in respective sections of the living room space are balanced. The control executer (53) repeatedly executes the energy-saving control on each air-conditioner (indoor device) in accordance with the control order set by the control order setter (52).
