Easily dismountable heat pump and method of manufacturing a heat pump
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current heat pump designs require the replacement of the entire compressor unit for maintenance or repair, which is cumbersome and costly due to its weight and size, necessitating two technicians and incurring high logistics costs.
Innovation Solution
The compressor diffusor is configured into two parts, with one part connected to the housing and the other to the motor, allowing the impeller to be removed through an opening, enabling easier disassembly and assembly by a single technician, reducing weight, and lowering logistics costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the entire compressor unit is replaced for maintenance, then the compressor can be serviced, but the weight and size require two technicians and increase logistics costs
Solution Approach 1:
The compressor is divided into separate components: the motor can be detached from the housing, and the impeller can be removed through an opening in the housing. This segmentation allows maintenance of individual components without replacing the entire compressor unit, reducing the weight that needs to be handled during maintenance from the full compressor weight to just the motor or impeller components.
2Ease of repair
If the entire compressor unit is replaced for maintenance, then the compressor can be serviced, but two technicians are required increasing labor complexity
Solution Approach 1:
The compressor is divided into separate components: the motor can be detached from the housing, and the impeller can be removed through an opening in the housing. This segmentation allows maintenance of individual components without replacing the entire compressor unit, reducing the weight that needs to be handled during maintenance from the full compressor weight to just the motor or impeller components.
Solution Approach 2:
The impeller is designed to be extractable through an opening in the housing without removing the motor or other components. This extraction principle allows technicians to access and service the impeller directly through the housing opening, eliminating the need to disconnect electrical connections or remove the motor assembly, thereby simplifying the maintenance operation to a single-technician task.
3Ease of repair
If the entire compressor unit is replaced for maintenance, then the compressor can be serviced, but logistics costs increase due to bulky goods classification

AI summary
A heat pump includes a housing; a liquefier and an evaporator arranged inside the housing; and a compressor interposed between the evaporator and the liquefier in terms of fluid flow, the compressor having a motor, an impeller connected to the motor, and a diffusor, the diffusor having a diffusor portion extending between the motor and the impeller, the diffusor portion having at least two parts, a first part of the diffusor portion being connected to the housing and a second part of the diffusor portion being connected to the motor, wherein the first part of the diffusor portion has an opening, wherein the second part of the diffusor portion is configured to close the opening, and wherein the opening is dimensioned such that the impeller is removable from the housing through the opening.
