ADAPTABLE CONSUMPTION HEATING OR COOLING SYSTEM

The object of the present invention is an electrically powered conditioning (heating or cooling) device of a fluid. The electrical power is provided by an energy source shared with other devices where the total available power is limited; moreover, it may also draw energy from renewable sources that vary over time. Such conditioning and temperature control device may modulate the electrical power absorption over a substantially continuous range of values, minimising the conditioning time without causing the maximum power threshold to be exceeded for more than a limited time and possibly benefits from the supply of power from renewable source. The controlled temperature is the temperature of a fluid accumulated in a tank, for example domestic hot water. The device receives information on the electrical power absorbed by the user, measured and transmitted by known means. According to the invention, the device estimates the activation time which guarantees reaching the target temperature at the required time and plans the activation accordingly. According to a first version, for the estimation of the activation time, the device follows the hypothesis of being able to use a fraction of its rated power; once activated, the device monitors the actual available power and it adapts (reducing or increasing) its consumption based on the real situation. In a second version, the device learns the hourly power consumption of the user, and in a further version it also foresees the power produced from a renewable source, and based on it, it estimates the future available hourly power and thus the activation strategy.
