Solution Overview
Problem
Conventional heat source devices with multiple units face challenges in reducing installation space and labor requirements due to exposed heat medium pipes, which complicate routing and layout, especially on roofs or in mechanical chambers.
Innovation Solution
The heat source device design features one end of the heat medium pipe inside the mechanical chamber, minimizing external connections and using flexible joints to maintain orderly pipe layout, reducing the need for external space and simplifying installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If heat medium pipes are connected outside the heat source device, then connection work can be performed, but installation space increases and routing becomes complicated
Solution Approach 1:
The heat medium pipes are nested inside the heat source device casing, with connection ports arranged so that pipes can be connected within the enclosed space rather than externally. This nesting approach eliminates the need for external pipe routing while maintaining connection functionality.
Solution Approach 2:
The connection ports are positioned on different surfaces of the heat source device (e.g., front and rear surfaces or adjacent side surfaces), utilizing three-dimensional spatial arrangement to enable internal pipe connection without increasing the device's external footprint.
2Ease of manufacture
If heat medium pipes are connected outside the heat source device, then connection can be made, but routing and layout become complicated especially on roofs or in mechanical chambers
Solution Approach 1:
By nesting the heat medium pipes inside the heat source device, the routing complexity is eliminated as pipes no longer need to be routed externally across roofs or through mechanical chambers. The connection is simplified to internal port-to-port connection.
3Power
If multiple heat source devices are installed, then heating or cooling capacity increases, but space for installation increases
Solution Approach 1:
Multiple heat source devices can be closely positioned or stacked due to the compact internal pipe connection design, effectively merging their spatial footprints. The elimination of external pipe routing allows devices to be installed in tighter configurations, increasing capacity without proportionally increasing installation space.
