Solution Overview
Problem
Existing refrigerant circuit apparatus evaluation systems lack the capability to determine whether the operation of one heat source unit adversely affects the operation of another heat source unit in a refrigerant circuit apparatus, particularly when multiple units are installed in close proximity.
Innovation Solution
A refrigerant circuit apparatus evaluation system that includes an acquisition unit to gather operation data from a first refrigerant circuit apparatus and a determination unit to assess whether the operation of a second heat source unit has an adverse effect on the first heat source unit, based on the acquired data when both units are simultaneously operating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple heat source units are installed in close proximity to save space, then the installation space efficiency is improved, but the operational reliability deteriorates due to adverse effects between units
Solution Approach 1:
The system continuously monitors operation data from multiple heat source units and uses the determination unit to assess adverse effects in real-time. When adverse effects are detected, the system can notify operators to adjust unit positions or operations, creating a feedback loop that maintains reliability despite close proximity installation
Solution Approach 2:
The evaluation system acts as an intermediary between multiple heat source units, detecting and assessing adverse effects that occur when units operate in close proximity. This intermediary system enables safe close installation by monitoring and managing the interactions between units
2Productivity
If multiple refrigerant circuit apparatuses are operated simultaneously to meet cooling/heating demands, then the productivity is improved, but the operational stability worsens due to mutual adverse effects
Solution Approach 1:
The system monitors operation data from multiple refrigerant circuit apparatuses and provides continuous feedback on adverse effects. This enables operators to adjust operations to maintain stability while utilizing multiple units for high productivity demands
Solution Approach 2:
The determination unit automatically assesses adverse effects using operation data from the apparatuses themselves, enabling the system to self-diagnose and alert operators to stability issues without external intervention
3Adaptability or versatility
If heat source units are installed in limited spaces to accommodate building constraints, then the adaptability is improved, but the measurement precision of operational parameters deteriorates due to interference
Solution Approach 1:
The evaluation system serves as an intermediary that compensates for measurement inaccuracies by analyzing operation data patterns and assessing adverse effects through multiple parameters, thereby maintaining measurement precision despite spatial constraints
Solution Approach 2:
The determination unit performs multiple functions including detecting adverse effects, assessing operational stability, and identifying installation issues, making the system robust against measurement uncertainties in constrained spaces

AI summary
Providing a refrigerant circuit apparatus evaluation system, which, when a plurality of refrigerant circuit apparatuses is installed, may accurately determine whether a heat source unit of each refrigerant circuit apparatus adversely affects the operation of a different refrigerant circuit apparatus. A refrigerant circuit apparatus evaluation system includes memory and processing circuitry. The processing circuitry acquires operation data on a first air-conditioning apparatus. The first air-conditioning apparatus includes a first heat source unit. The processing circuitry determines whether an operation of a second heat source unit different from the first heat source unit has an adverse effect on an operation of the first heat source unit based on the operation data on the first air-conditioning apparatus acquired by the processing circuitry when the first air-conditioning apparatus and a second air-conditioning apparatus including the second heat source unit are simultaneously operating.
