Air conditioning system for selectively suppressing indoor and outdoor unit operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioning systems face inefficiencies and increased power consumption due to the continued operation of outside air processors even when indoor units are in suppression or stop modes.
Innovation Solution
The air conditioning system incorporates a control device that synchronizes the operation of outdoor and inside units, causing the outside air processor to shift to output restriction or stop modes when indoor units enter these states, thereby reducing unnecessary operation and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the outside air processor continues to operate independently of indoor unit status, then it can maintain air processing capability, but power consumption increases unnecessarily
Solution Approach 1:
The patent merges the control of the outside air processor with the indoor units by introducing a control device that receives operation status information from indoor units and automatically controls the outside air processor accordingly. This integration ensures the outside air processor operates only when indoor units are operating, eliminating unnecessary power consumption while maintaining coordinated air processing capability.
2Reliability
If the outside air processor operates continuously, then air quality control is maintained, but unnecessary operation occurs when indoor units are stopped
Solution Approach 1:
The patent implements a feedback mechanism where the control device receives operation status information from indoor units and uses this feedback to automatically control the outside air processor. When indoor units are operating, the outside air processor is controlled to operate and maintain air quality; when indoor units are stopped, the outside air processor is also stopped, eliminating wasteful energy use while maintaining reliability during active operation.
3Loss of energy
If the outside air processor is controlled to stop when indoor units stop, then power consumption is reduced, but coordination between units is lost
Solution Approach 1:
The patent makes the control device universal by enabling it to perform multiple functions: receiving operation status information from indoor units, determining their operational state, and automatically controlling the outside air processor based on this information. This multi-functional control device simplifies the overall system architecture while achieving coordinated operation and reduced power consumption.

AI summary
An air conditioning system includes an outdoor unit including a control device, an indoor unit communicably connected to the control device, and an outside air processor communicably connected to the control device. The indoor unit is capable of performing ordinary operation control to adjust a temperature of air in a room, the air being taken in the indoor unit, and supply the air into the room, and output restriction control under which an output is restricted as compared with an output under the ordinary operation control. The outside air processor is capable of performing ordinary operation control to adjust at least one of a temperature and a humidity of air outside the room, the air being taken in the outside air processor, and supply the air into the room, and output restriction control under which an output is restricted as compared with an output under the ordinary operation control. The control device causes the outside air processor to shift from the ordinary operation control to the output restriction control on condition that the indoor unit shifts from the ordinary operation control to the output restriction control.
