Tandem Compressor Slide Rail for Easier HVAC Servicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
HVAC systems with tandem compressor arrangements face difficulties in accessing and servicing components due to shared oil connections and rigid mounting, making maintenance and repair cumbersome and time-consuming.
Innovation Solution
A slide rail system with a slide plate that allows compressors to be slidably attached, providing a locking mechanism for secure positioning and easy access, while maintaining vibrational isolation and allowing for independent movement of compressors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If compressors are rigidly mounted with shared oil connections, then structural stability is improved, but ease of repair deteriorates
Solution Approach 1:
The patent applies the dynamics principle by transitioning from a rigid, fixed mounting system to a dynamic, movable mounting system. The compressors are mounted on a slide plate that can move along a slide rail, allowing the compressors to be easily removed and reinstalled. This dynamic mounting mechanism maintains structural stability during operation while enabling easy access for repair by allowing the slide plate to be pulled out horizontally without disconnecting fluid lines or oil connections.
Solution Approach 2:
The patent applies segmentation by dividing the compressor assembly into separable components: the compressors are individually mounted on a common slide plate, which itself is separable from the HVAC system via the slide rail mechanism. This segmentation allows the slide plate with compressors to be removed as a unit while leaving the fluid connections intact, facilitating easy maintenance without requiring disconnection of multiple joints.
2Area of stationary object
If multiple components are squeezed into small area, then space utilization is improved, but ease of operation deteriorates
Solution Approach 1:
The slide rail mechanism transforms the static, space-constrained compressor arrangement into a dynamic system where the compressors can be easily accessed by horizontal movement. The compact tandem configuration is maintained within the HVAC unit, but the movable mounting allows operators to quickly remove compressors for servicing without having to work in the confined space or disconnect multiple components.
3Ease of repair
If compressors are removed for servicing, then ease of repair is improved, but loss of substance worsens
Solution Approach 1:
The patent segments the mounting system from the fluid connections. The slide plate with compressors can be removed as a complete unit while the fluid lines remain connected to the HVAC system. This segmentation allows the compressors to be serviced without breaking oil connections or fluid line joints, preventing oil loss and contamination that would occur with traditional removal methods.
Solution Approach 2:
The slide rail mechanism acts as an intermediary that enables compressor removal without requiring disconnection of fluid connections. This intermediary mounting system allows the compressors to be extracted horizontally while the fluid lines remain stationary and connected, serving as a mediator between the need for easy removal and the need to maintain sealed fluid connections.

AI summary
A system and method are disclosed for compressor units in HVAC systems. A slide plate and slide rail assembly is described that can allow compressors to be slidably removed or adjusted to allow for easy repair or servicing. Instead of disassembling an entire compressor unit when repairs are needed on it or on neighboring components, the compressor unit can be quickly moved. Dual slide rail and slide plate configurations are described as well.
