Solution Overview
Problem
Conventional sorption cold devices face inefficiencies due to the need for separate throttling components, which are prone to pressure fluctuations and energy consumption, and often require pumps, leading to increased maintenance and energy usage.
Innovation Solution
The sorption cold device employs the connection means itself as a primary throttle, eliminating separate throttling components and optimizing pressure regulation, allowing for efficient operation without pumps and reduced energy consumption by arranging the sorption chamber directly between the evaporator and capacitor, with the capacitor positioned deeper than the evaporator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If separate throttling components (capillary tubes, expansion valves) are used to reduce pressure difference between capacitor and evaporator, then pressure regulation is achieved, but pressure losses increase and system complexity increases
Solution Approach 1:
The patent merges the throttling function with the connection means itself. The connecting agent serving as the primary throttle device combines the functions of connection and pressure regulation into a single component, eliminating separate throttling components and reducing pressure losses associated with additional throttle organs.
Solution Approach 2:
The connection means is designed to perform multiple functions: it serves as both the connecting conduit between capacitor and evaporator, and as the primary throttling device. This multi-functionality eliminates the need for separate throttling components and reduces system complexity.
2Productivity
If pumps are used to promote refrigerant flow and media funding, then refrigerant circulation is improved, but energy consumption and maintenance requirements increase
Solution Approach 1:
The system uses the connecting agent as a self-regulating primary throttle that automatically controls refrigerant flow based on pressure differences without requiring external power or mechanical pumps. The refrigerant circulation is achieved through the inherent pressure-driven flow control of the connection means.
Solution Approach 2:
The patent replaces mechanical pumps with a passive pressure-driven flow control system. The connecting agent serves as a primary throttle that regulates refrigerant flow through pressure differences alone, eliminating the need for mechanically moving components and pump-driven circulation.
3Ease of operation
If capacitor is arranged above evaporator to promote condensed refrigerant by gravity, then refrigerant flow is improved, but pressure backflow can occur and additional height arrangement is required
Solution Approach 1:
The connecting agent acts as an intermediary between capacitor and evaporator, serving as both the flow path and the primary throttle. This intermediary function allows the system to maintain pressure stability while enabling refrigerant flow without requiring the capacitor to be positioned above the evaporator, preventing pressure backflow issues.
4Reliability
If throttle devices (capillary tubes, expansion valves) are installed to prevent pressure back, then pressure stability is improved, but pressure losses increase and system complexity increases
Solution Approach 1:
The patent combines the pressure regulation and flow control functions into the connecting agent itself, which serves as the primary throttle. This merging eliminates the need for separate throttle devices and additional pressure control components, reducing system complexity while maintaining pressure stability.
Solution Approach 2:
The connection means is designed to perform multiple functions including serving as the primary throttle device for pressure regulation. This multi-functionality eliminates the need for separate pressure control components and reduces the overall number of parts in the system.
