Solution Overview
Problem
The existing multiple-type air conditioning machines require a large and heavy refrigerant collection cylinder, increasing the operational load when collecting refrigerant, as the refrigerant circuit contains more refrigerant than pair-type machines, making the process cumbersome and labor-intensive.
Innovation Solution
A refrigerating device with a detachable refrigerant collection container integrated into the outdoor unit, allowing the refrigerant to be collected and stored within the device itself, reducing the need to transport a heavy external cylinder and providing protection and ease of operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a refrigerant collection cylinder is used to collect refrigerant from the refrigerant circuit, then the refrigerant can be collected and stored, but the cylinder becomes large and heavy requiring operator transport to the installation site
Solution Approach 1:
The patent merges the refrigerant collection container with the outdoor unit, integrating two separate functions (refrigerant collection and outdoor heat exchange) into a single integrated system. This eliminates the need for separate transport of collection cylinders while maintaining full refrigerant collection capacity.
Solution Approach 2:
The outdoor unit serves dual purposes: it functions as both the heat exchange component and the refrigerant collection container. The system performs self-service by using its existing structure to collect and store refrigerant, eliminating the need for external collection equipment.
2Quantity of substance
If a large refrigerant collection cylinder is used to accommodate the greater refrigerant amount in multiple-type air conditioning machines, then all refrigerant can be collected, but the operation becomes labor-intensive and cumbersome
Solution Approach 1:
By combining the refrigerant collection container with the outdoor unit, the patent eliminates the need for operators to transport heavy cylinders to installation sites, significantly improving ease of operation while maintaining the ability to collect all refrigerant from the system.
Solution Approach 2:
The patent extracts the refrigerant collection function from the portable cylinder concept and integrates it into the stationary outdoor unit, removing the operational burden of transport while preserving the collection capability.
3Reliability
If an external refrigerant collection cylinder is brought to the installation site, then refrigerant collection is possible, but the operator must transport heavy equipment to the location
Solution Approach 1:
The patent merges the refrigerant collection container with the outdoor unit, ensuring reliable refrigerant collection capability is maintained while eliminating the need for operator transport of separate collection equipment to the installation site.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reduces the operational load by allowing refrigerant collection without the need for a large external cylinder, protects the collection container from external impacts, and facilitates easier handling and operation, while also enabling efficient refrigerant management and reuse.
Implementation Method 1
In a cooling operation, more specifically, the refrigerant is delivered from the compressor to an outdoor heat exchanger in the outdoor unit and the outdoor heat exchanger functions as a condenser. In a heating operation, the refrigerant is delivered from the compressor to an indoor heat exchanger in each indoor unit and the indoor heat exchanger functions as a condenser.
Implementation Method 2
the refrigerant is delivered from the compressor to an outdoor heat exchanger in the outdoor unit and the outdoor heat exchanger functions as a condenser
