Solution Overview
Problem
Conventional two-pipe receivers in multi-function heat pump systems cannot function to store or release refrigerant effectively in all modes, leading to dead zones and refrigerant shortages during system operation.
Innovation Solution
A three-pipe receiver design with specific pipe configurations and check valves that allow refrigerant flow between multiple load units and a cold and heat source unit, enabling operation in various modes regardless of the system configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional two-pipe receiver is used in a multi-function heat pump system, then the structure is simple and cost-effective, but the receiver cannot function to store or release refrigerant in all operating modes, creating dead zones
Solution Approach 1:
The receiver is designed with three pipes (first pipe connected to first load unit, second pipe connected to second load unit, third pipe connected to cold and heat source unit) instead of the conventional two pipes, enabling it to function in all operating modes including heating, cooling, and heat pump modes. This multi-functional configuration eliminates dead zones by ensuring the receiver is always connected to the thermal cycle regardless of which units are operating.
2Reliability
If the receiver is not connected to a thermal cycle in certain modes, then the structure remains simple, but the receiver forms dead zones where refrigerant cannot be used for system operation
Solution Approach 1:
The three-pipe configuration ensures the receiver remains connected to the thermal cycle in all operating modes. The first pipe connects to the first load unit, the second pipe connects to the second load unit, and the third pipe connects to the cold and heat source unit, creating redundant pathways that guarantee refrigerant circulation regardless of which units are active.
Solution Approach 2:
Different sections of the receiver system have specialized functions: the first pipe section handles refrigerant flow to/from the first load unit, the second pipe section handles the second load unit, and the third pipe section handles the cold and heat source unit. This localized functional differentiation ensures optimal refrigerant management in each specific operating mode.
