Refrigerating Cycle Remote Operation Control to Reduce Accident Risk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a risk of accidents occurring when refrigerating cycle devices, such as air conditioners, are operated remotely from outside the structure, particularly due to high electric power usage and potential electrical system failures, which can lead to safety hazards and energy inefficiencies.
Innovation Solution
A refrigerating cycle apparatus with a control device that reduces the operation capacity when the device is operated from outside, using a microcomputer to manage the operation capacity and stagger the start times of multiple devices, thereby lowering electric power consumption and mitigating accident risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the refrigerating cycle device is operated remotely from outside the structure, then the convenience of operation is improved, but the risk of accidents increases due to high electric power usage and potential electrical system failures
Solution Approach 1:
The control device limits the operation capacity to a predetermined value that is lower than the maximum capacity of the refrigerating cycle device. This partial action approach allows remote operation to be enabled while preventing excessive power consumption and reducing accident risk by operating the device within safe capacity thresholds.
Solution Approach 2:
The operation capacity parameter is changed based on the operation location. When remote operation is detected, the control device sets the operation capacity to a predetermined limited value. This parameter change resolves the contradiction by adjusting the operating conditions to balance convenience with safety.
2Speed
If the refrigerating cycle device operates at high capacity to quickly cool or heat the room, then the air conditioning effectiveness is improved, but the electric power consumption increases
Solution Approach 1:
Instead of operating at maximum capacity, the device operates at a predetermined limited capacity that is sufficient for air conditioning but consumes less power. This partial action resolves the contradiction by providing adequate cooling/heating effect while avoiding excessive energy consumption.
Solution Approach 2:
The control device may operate the refrigerating cycle device in intermittent periods rather than continuous high-capacity operation. This periodic action allows the room to be cooled or heated over time while reducing peak power consumption and overall energy usage.

AI summary
A refrigerating cycle apparatus includes a refrigerating cycle device having a refrigerating cycle, the refrigerating cycle in which a refrigerant is compressed in a compressor and made to circulate, and by a heat exchanger, heat is absorbed from a low temperature heat source and heat is exhausted to a high temperature heat source, and a control device that controls operation of the refrigerating cycle device. An obtaining unit obtains an operation operating request that controls the refrigerating cycle device arranged in a structure's interior to a target state. An operation control unit, when the operation operating request transmitted from an outside is obtained, controls the refrigerating cycle device to the target state with lower operation capacity than operation capacity of the refrigerating cycle device of a case where the operation operating request is transmitted from the structure's interior.
