Outdoor Unit Filter Layout for Easier Heat Pump Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioning apparatuses face poor workability due to the need for external mounting of electromagnetic valve units, including filters, during installation, which complicates the process.
Innovation Solution
A heat pump design where the gas-side and liquid-side filters are integrated within the package of the outdoor unit, eliminating the need for external mounting and allowing for improved installation efficiency by utilizing the package's space effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the electromagnetic valve unit with built-in strainer or filter is provided outside the package of the outdoor unit, then the filter can be mounted externally, but the installation workability deteriorates due to the need to ensure a place for mounting the filter at the time of installation on site
Solution Approach 1:
The patent merges the filter mounting function into the outdoor unit package itself. The filter holder is integrated within the package, allowing the filter to be mounted internally rather than externally. This eliminates the need to ensure separate external mounting space while maintaining filter functionality, thereby improving installation workability.
Solution Approach 2:
The patent utilizes the internal three-dimensional space within the outdoor unit package to accommodate the filter and filter holder. By transitioning from external two-dimensional mounting to internal three-dimensional integration, the design eliminates the need for external mounting space while preserving filter accessibility and functionality.
2Device complexity
If the filter is mounted outside the package, then the package structure remains simple, but the installation process becomes more complex due to additional external mounting requirements
Solution Approach 1:
The filter mounting function is merged into the package structure itself. The filter holder is designed as an integrated component within the package, eliminating the need for separate external mounting brackets or structures. This integration maintains package simplicity while significantly improving installation efficiency by reducing the number of external components to be installed.
3Ease of operation
If the gas-side filter and liquid-side filter are mounted on the indoor unit side relative to the stop valves and inside the package, then the workability is improved by eliminating external mounting space requirements, but the package internal space must be adequately designed
Solution Approach 1:
The patent utilizes the internal three-dimensional space of the package to accommodate both filters and their holders. By designing the filter holder to fit within the existing package volume and utilizing vertical and horizontal dimensions efficiently, the package can contain the filters without requiring excessive external mounting space, thereby improving workability while managing internal space requirements.

AI summary
A gas-side stop valve on the gas refrigerant side and a liquid-side stop valve on the liquid refrigerant side are provided in a package of an outdoor unit. A gas-side filter on the gas refrigerant side is mounted on the indoor unit side relative to the gas-side stop valve and inside the package of the outdoor unit. A liquid-side filter 9 on the liquid refrigerant side is mounted on the indoor unit side relative to the liquid-side stop valve and inside the package of the outdoor unit. As a result, it is not necessary to ensure a place for mounting the gas-side filter and the liquid-side filter at the time of installation on site and the workability can be improved.
