Outdoor Air Conditioner Unit with External Refrigerant Charging Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation and maintenance of outdoor air conditioner units are inefficient due to the need to disassemble large panels for system pressure detection, vacuuming, and refrigerant addition, which complicates the process and reduces efficiency.
Innovation Solution
An outdoor air conditioner unit design featuring a FREON charging nozzle with a connector assembly that allows for guiding the nozzle from inside to outside the housing without disassembling the panel, using a communication tube with a connector extending out of the housing, and a cover plate for protection, simplifying detection, installation, and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the panel is disassembled for system pressure detection, vacuuming, or refrigerant addition, then these operations can be performed, but the operation process becomes complicated and efficiency is reduced
Solution Approach 1:
The charging nozzle is extracted from the interior of the outdoor machine and extended to the exterior through the connector assembly. This allows the nozzle to be accessible from outside the housing, eliminating the need to disassemble the panel for charging operations while maintaining the sealed interior structure.
Solution Approach 2:
The connector assembly acts as an intermediary structure that bridges the interior charging nozzle and the exterior environment. It provides a passage for the nozzle to extend through the housing wall, allowing external access to the charging function without compromising the panel's integrity or requiring its removal.
2Ease of repair
If the panel is disassembled for maintenance operations, then system pressure can be detected, but the large sized panel makes disassembly and reassembly time-consuming
Solution Approach 1:
The charging nozzle is extracted from the interior of the outdoor machine and extended to the exterior through the connector assembly. This allows the nozzle to be accessible from outside the housing, eliminating the need to disassemble the panel for charging operations while maintaining the sealed interior structure.
Solution Approach 2:
The connector assembly is pre-installed on the housing during manufacturing, with the charging nozzle already positioned and connected internally. This preliminary setup ensures that the nozzle is ready for external access without requiring any disassembly of the panel during maintenance operations.
