Abstract

The invention pertains to a computer-implemented method for automatically controlling the temperature of a heat transfer fluid supplied from a heat pump (10) to heat exchanger units (12) of a floor heating system (100) in a building, particularly a residential one. The system includes at least two independently controlled thermal control zones (20, 22) for heating and/or cooling. The method involves receiving building characteristics data (30), weather forecast data (32), predefined setpoint climate data (34), and measured climate data (36) from each thermal control zone (20, 22). The method is characterized by determining sequential weather data and climate deviation data using a processing unit. This data, along with the building characteristics data (30), is transmitted to a data-driven control unit. The control unit analyzes the input data using a trained control model, developed through a machine learning algorithm and a dataset of simulated data indicative of the building's thermal behavior and the floor heating system's (100) performance under varying weather conditions. The control unit determines an optimum supply fluid temperature, defined as the minimum temperature of the heat transfer fluid that maintains the measured climate data (36) within defined thresholds centered on the setpoint climate data. The temperature of the heat transfer fluid is then controlled based on the determined optimum supply fluid temperature.
