Solution Overview
Problem
Existing air conditioner safety systems fail to provide timely protection against refrigerant leakage and potential explosions during installation, particularly in the first installation after sale and relocation scenarios, due to long judgment times and reliance on temperature-based methods.
Innovation Solution
A method and apparatus that determine the refrigerant circulation state by analyzing the current change situations of the air conditioner outdoor unit and compressor within a short power-on duration, generating an abnormity protection instruction to halt the compressor, implementing the protection by using the change situations of the air conditioner outdoor unit and compressor current, thereby improving timeliness and reducing unnecessary protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If temperature-based methods are used to detect refrigerant leakage, then the safety protection is provided, but the judgment time is long and timeliness is poor
Solution Approach 1:
The patent changes the detection parameter from temperature to current. By monitoring current changes in the outdoor unit and compressor, the system can detect refrigerant circulation abnormalities much faster than temperature-based methods, directly resolving the timeliness issue while maintaining safety protection
Solution Approach 2:
The patent replaces the thermal detection mechanism with an electrical detection mechanism. Instead of waiting for temperature changes that occur slowly, the system uses electrical current measurements which respond immediately to refrigerant circulation issues, achieving both speed and reliability
2Reliability
If protection is provided during long running periods, then safety is ensured, but unnecessary protection occurs during normal operation
Solution Approach 1:
The patent performs preliminary detection during the startup phase (first preset duration) before normal operation begins. By checking refrigerant circulation state initially and only during this critical period, the system prevents false protections during stable running while ensuring safety when it matters most
Solution Approach 2:
The patent dynamically adjusts the detection strategy based on operating phase. During startup, intensive current monitoring is performed; during stable operation, monitoring is reduced or stopped. This dynamic approach eliminates unnecessary protections while maintaining safety during critical transitions
3Measurement precision
If current change monitoring is performed continuously, then detection precision is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic current monitoring only during the first preset duration after startup, rather than continuous monitoring. This time-limited periodic detection achieves sufficient precision for catching startup abnormalities while dramatically reducing energy consumption during prolonged operation
Solution Approach 2:
The patent applies excessive detection precision only when needed (during startup phase with potential abnormalities) and reduces monitoring during normal operation. This partial application of intensive monitoring optimizes the balance between detection precision and energy consumption

AI summary
The invention relates to a method and apparatus for controlling an air conditioner, an electronic device, an air conditioner, a storage medium and a product, and relates to the field of air conditioners. The method provides that a power-on duration of an air conditioner indoor unit is determined (S11), a refrigerant circulation state of the air conditioner is determined (S12) based on a current change situation of an air conditioner outdoor unit and a current change situation of an air conditioner compressor in a case that the power-on duration is less than a first preset duration, and an abnormity protection instruction for controlling the air conditioner compressor to perform a halt protection is generated (S13) in a case that the refrigerant circulation state is abnormal.
