Solution Overview
Problem
Existing heating systems, particularly in zone systems, exhibit poor energy optimization and inefficient heating or cooling performance, especially when adjusting to room-specific temperature setpoints, leading to high energy costs.

A method for optimizing heating system performance by calculating and adjusting the flow temperature of a heat transfer fluid based on zone-specific setpoint and ambient air temperatures, using sensors and a calculation unit to determine optimal operating conditions for fan coils and energy transformation equipment, including automatic adjustments via wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If zone systems provide heating for each room individually, then temperature control precision is improved, but energy optimization deteriorates
Solution Approach 1:
The system dynamically adjusts the flow temperature parameter of the heat transfer fluid based on real-time temperature measurements from each zone. By changing this critical parameter adaptively rather than using fixed temperatures, the system achieves both precise zone-specific temperature control and optimized energy consumption through matching supply temperatures to actual heating demands.
2Speed
If fan coils operate at maximum power to reach setpoint temperature quickly, then heating speed is improved, but energy consumption increases
Solution Approach 1:
The fan coil units dynamically adjust their operating power based on real-time feedback from temperature sensors. Rather than operating statically at maximum power, the system modulates fan coil output to match the actual heating requirement, achieving rapid initial heating followed by efficient maintenance mode, thus balancing heating speed with energy consumption.
3Temperature
If flow temperature is increased to meet higher zone temperature demands, then temperature satisfaction is improved, but heat pump COP deteriorates
Solution Approach 1:
The system segments the heating demand by zone and calculates the minimum required flow temperature for each zone individually based on its specific temperature deficit and fan coil characteristics. This segmented approach allows the heat pump to supply different temperatures to different zones through multiple fan coils, avoiding the need to raise the flow temperature for all zones simultaneously, thus preserving heat pump COP while satisfying individual zone temperature requirements.
