Solution Overview
Problem
When air conditioners from different manufacturers are matched, the presence of refrigeration throttle assemblies on both the outdoor and indoor sides can result in double throttle valves, causing noise and discomfort due to the unnecessary throttling.
Innovation Solution
An air conditioner control method that detects the presence of a refrigeration electronic expansion valve in the path between the indoor and outdoor units, controlling the refrigeration throttle valve to close and the solenoid valve to open, and activating the electronic expansion valve to throttle the system, thereby bypassing the solenoid valve and reducing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If products from different manufacturers are matched with refrigeration throttle assemblies on both outdoor and indoor sides, then the system can function with redundant throttling capability, but double throttle valves are formed causing noise and discomfort
Solution Approach 1:
The system dynamically switches between different throttling configurations based on detected presence of electronic expansion valves. The control method enables the refrigeration system to adapt its throttling architecture in real-time, selecting either the electronic expansion valve or the refrigeration throttle valve assembly depending on system configuration, thereby eliminating simultaneous operation of both valves that causes noise
Solution Approach 2:
The control method extracts or isolates the problematic double-throttle configuration by detecting the presence of electronic expansion valves and subsequently controlling the refrigeration throttle valve to close and the refrigeration solenoid valve to open, effectively removing the outdoor throttle valve from active service when the indoor electronic expansion valve is present, thus eliminating the noise source
2Productivity
If the refrigeration throttle valve is activated for throttling, then the system can control refrigerant flow, but noise is generated on the indoor side affecting comfort
Solution Approach 1:
The refrigeration solenoid valve acts as an intermediary component that redirects refrigerant flow. When the electronic expansion valve is detected, the solenoid valve opens to provide an alternative flow path that bypasses the noisy refrigeration throttle valve, allowing refrigerant to flow through the electronic expansion valve instead, thus maintaining flow control while eliminating noise
Solution Approach 2:
The control method substitutes the mechanical refrigeration throttle valve with the electronically controlled expansion valve. By detecting the presence of the electronic expansion valve and controlling the solenoid valve to redirect flow, the system replaces the noisy mechanical throttling mechanism with an electronic control system that operates more quietly

AI summary
An air conditioner control method includes in response to that an air conditioner is in a refrigeration mode, detecting whether a refrigeration electronic expansion valve exists in a path communicating an indoor unit and an outdoor unit of the air conditioner; and in response to determining that the refrigeration electronic expansion valve exists in the path, controlling a refrigeration throttle valve to close and a refrigeration solenoid valve to open. The refrigeration throttle valve and the refrigeration solenoid valve are provided in parallel in the path. The method further includes activating the refrigeration electronic expansion valve to throttle the air conditioner.
