Implication

Randomized trial evaluates a control logic for optimizing heating supply in distributed air source heat pump systems, improving efficiency and reducing costs.

Key Points

The study aims to enhance operational stability and energy efficiency in air source heat pump heating systems through a new regulation method.
Proposed a time-period control logic for heating supply in radiant floor heating systems.
Conducted a field experiment in a residential community in Hebei, China.
Analyzed energy-saving and economic performance using typical day calculations.
Achieved total energy-saving rates of about 8% and cost-saving rates of 10%.
Maximum deviations of supply and return water temperatures were 0.72 °C and 0.41 °C with the proposed control logic.
Indoor temperature remained within ±2 °C of the setpoint under the new regulation method.
