Abstract: In a joint water boiler-air/air heat pump air conditioning system coupled to a photovoltaic system and intended to air condition a closed environment formed by one or more rooms and comprising an electrical system to which electrical appliances are connected, an electronic control system is programmed to compute electrical power production of the photovoltaic system and electrical power consumption of the electrical appliances in the closed environment, and, based thereon, a surplus electrical power production of the photovoltaic system with respect to the electrical power consumption of the electrical appliances in the closed environment. If a surplus of electrical power production of the photovoltaic system is determined to exist with respect to the electrical power consumption of the electrical appliances in the closed environment, it may be determined how many indoor units of the hot/cold air/air heat pump system can be electrically supplied simultaneously with the electrical power surplus.

Abstract: An electronic control system to control exploitation of electrical power produced by a household photovoltaic system to electrically power remotely electronically-controllable electric household appliances. The household photovoltaic system is electrically connected to a public electrical power mains and to a household electric system via an electronic electrical power meter configured to measure the electrical power produced by the household photovoltaic system and the electrical power absorbed from or supplied to the public electrical power mains as a result of an electrical power underproduction or overproduction of the household photovoltaic system compared to the electric power consumption of the household electric system.
