Solution Overview
Problem
The existing systems for heating consumer water and water-borne heat in modern dwellings are complex and costly to install and maintain, requiring separate receptacles and multiple temperature sensors for heat pump control, which complicates adjustments and increases energy consumption.
Innovation Solution
A dual-receptacle arrangement with interconnected piping and energy exchange elements, where a heat source, such as a heat pump, is controlled by a single setpoint sensor, allowing energy transfer between the receptacles to optimize temperature control and reduce installation and maintenance costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate receptacles and multiple temperature sensors are used for heat pump control, then temperature control of consumer water and water-borne heat is achieved, but device complexity and installation costs increase
Solution Approach 1:
The patent combines the control of two separate receptacles (consumer water heater and water-borne heat system) into a single heat pump system controlled by one temperature sensor. The heat pump's compressor is controlled based on the temperature reading from a single sensor, merging what would traditionally require separate control systems into one unified control mechanism, thereby reducing device complexity while maintaining temperature control reliability
Solution Approach 2:
The heat pump system is designed to serve multiple functions simultaneously - heating consumer water and providing water-borne heat - through a single controlled system. The universal control mechanism using one temperature sensor manages both receptacles, eliminating the need for separate specialized control systems for each function and reducing overall system complexity
2Measurement precision
If multiple temperature sensors and complex control systems are installed, then precise temperature control is achieved, but installation and maintenance costs increase
Solution Approach 1:
The patent extracts and eliminates the unnecessary temperature sensors and complex control mechanisms from the system. By determining that only one temperature sensor is needed to control the heat pump for both receptacles, the design removes redundant sensing and control components, thereby reducing installation and maintenance costs while preserving the necessary measurement precision through the single sensor
Solution Approach 2:
The system adopts a simpler, more cost-effective control approach using a single temperature sensor and basic heat pump control logic, replacing expensive and complex multi-sensor control systems. This simplification reduces both initial installation costs and ongoing maintenance expenses while maintaining adequate temperature control precision
3Ease of operation
If separate heating systems for consumer water and water-borne heat are used, then independent temperature control is achieved, but energy consumption increases
Solution Approach 1:
The patent merges the heating functions for consumer water and water-borne heat into a single heat pump system. By combining these separate heating operations into one unified system controlled by a single temperature sensor, the system optimizes energy usage through coordinated operation, reducing total energy consumption compared to running separate independent heating systems

Function Achieved in This Case
This solution simplifies the temperature control of both consumer water and water-borne heat systems, reducing energy consumption and costs by allowing for efficient energy transfer and preheating of water, enabling the heat pump to operate efficiently with a single control point.
