Solution Overview

Problem

Multi-type air conditioning devices with numerous indoor units connected to a single outdoor unit face challenges due to complex and lengthy refrigerant piping, which increases installation costs and reduces energy efficiency, while also affecting the aesthetic appeal of the installation space.

Innovation Solution

The integration of a detachable or embedded distribution unit within the outdoor unit that connects multiple indoor units to the outdoor unit via a modular structure, minimizing the length of refrigerant pipes and allowing for flexible installation positions, thereby reducing installation complexity and enhancing energy efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple indoor units are connected to a single outdoor unit using conventional piping methods, then the air conditioning system can serve multiple rooms, but the refrigerant piping becomes complex and lengthy, increasing installation costs and reducing energy efficiency

Engineering Contradiction:
Improvenumber of indoor units connectedVSAvoidrefrigerant piping complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The distribution unit acts as an intermediary component between the outdoor unit and multiple indoor units. It receives refrigerant from the outdoor unit and distributes it to multiple indoor units through integrated piping, thereby simplifying the overall system architecture and reducing piping complexity while maintaining the ability to connect multiple indoor units

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple indoor units are connected to a single outdoor unit, then the air conditioning system can serve multiple rooms, but the refrigerant pipe length increases, reducing energy efficiency

Engineering Contradiction:
Improvenumber of indoor units connectedVSAvoidenergy efficiency
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The distribution unit merges the refrigerant distribution function for multiple indoor units into a single integrated component. By combining the piping routes and distribution logic within one unit, the total refrigerant pipe length is reduced compared to conventional separate connections, thereby improving energy efficiency while maintaining adaptability to multiple indoor units

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If conventional piping methods are used to connect multiple indoor units to the outdoor unit, then the system can be installed, but the installation becomes complex and time-consuming

Engineering Contradiction:
Improvenumber of indoor units connectedVSAvoidinstallation ease
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The distribution unit is designed as a separate, modular component that can be manufactured independently and then installed as a single unit between the outdoor unit and multiple indoor units. This segmentation of the distribution function into a dedicated module simplifies the installation process, as the complex piping arrangement is pre-assembled in the distribution unit rather than being installed site-by-site

Inventive Principle:
Principle #1Segmentation

AI summary

An air conditioning device is provided that includes an outdoor unit and a distribution unit. In the air conditioning device, a length of pipes that connect a plurality of indoor units to the outdoor unit is minimized to improve aesthetic appeal and efficiency, and pipes are arranged in the distribution unit for interconnecting the indoor units and the outdoor unit efficiently so as to minimize the volume of the distribution unit. The distribution unit may have a modular structure such that single or multiple distribution units may be added or removed as needed.
