Multi-Room Air Conditioner Noise-Reduction Mode Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-room air conditioners lack the ability to individually adjust the operating mode of a heat source unit to accommodate varying noise reduction requirements across different rooms, leading to suboptimal noise reduction operations.
Innovation Solution
A control apparatus that allows the heat source unit to be switched among multiple operating modes with different noise-reduction levels, with an operating mode allocator determining the optimal mode for each conditioning unit based on user requests, ensuring that each room's requirements are met while minimizing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single operating mode is selected for the heat source unit to serve all rooms, then the system structure remains simple, but the noise reduction requirements of different rooms cannot be individually met
Solution Approach 1:
The patent segments the control system into two functional modules: an operating mode allocator that distributes different operating modes to different conditioning units based on room requirements, and an operating mode setter that executes the allocation. This segmentation allows each room to have its noise reduction requirements met independently while keeping the overall system structure manageable through clear functional division.
2Object-affected harmful factors
If the heat source unit operates in reduced-noise mode, then noise levels decrease, but air conditioning performance may be insufficient for rooms with high cooling/heating demands
Solution Approach 1:
The patent implements dynamic operating mode selection where the heat source unit can switch between regular operating mode and multiple reduced-noise operating modes (with progressively higher noise-reduction levels) based on real-time room requirements. The system dynamically allocates appropriate operating modes to different conditioning units, ensuring that rooms with high performance needs receive adequate cooling/heating while noise-sensitive rooms operate in reduced-noise modes.
3Object-affected harmful factors
If multiple reduced-noise levels are provided, then noise reduction can be optimized for different rooms, but the control system becomes more complex
Solution Approach 1:
The patent applies local quality by providing multiple reduced-noise operating modes with progressively higher noise-reduction levels, allowing different rooms to receive appropriately tailored noise reduction. The operating mode allocator assigns specific noise-reduction levels to different conditioning units based on individual room requirements, enabling localized optimization without requiring complete system redesign.

AI summary
In a multi-room air conditioner, requests from rooms are adjusted when one operating mode is selected from a plurality of operating modes having different noise-reduction levels. A heat source side controller (20) of an air conditioner (1) has an operating mode allocator (22) and an operating mode setter (23). The air conditioner (1) has a heat source unit (2) and a plurality of room units (3). The heat source unit (2) can be switched among a plurality of operating modes having different noise-reduction levels. The operating mode allocator (22) allocates one operating mode to each of the operating room units (3). The operating mode setter (23) sets the heat source unit (2) to one operating mode from among the plurality of operating modes on the basis of the operating modes allocated by the operating mode allocator (22) to each of the operating room units (3). In cases in which a specific operating mode is allocated to all of the operating room units (3), the operating mode setter (23) sets the heat source unit (2) to the specific operating mode.
