Exploitation of a photovoltaic system coupled to a joint water boiler-air/air heat pump air conditioning system

An electronic control system for 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;

• the joint water boiler-air/air heat pump air conditioning system comprising:
• a radiator heating system comprising a water boiler to produce hot water, and one or more radiators intended to be installed in the rooms of the closed environment, fluidically connected to the water boiler to be flown through by the hot water produced by the water boiler, and equipped with thermostatic valves to set desired temperatures in the rooms of the closed environment in which they are installed;
• and
• a hot/cold air/air heat pump system comprising one or more outdoor units intended to be installed outside the closed environment, and one or more indoor units intended to be installed in the rooms of the closed environment;
• the electronic control system comprising:
• one or more (chrono)thermostats intended to be installed in one or more of the rooms of the closed environment to switch the water boiler on and off;
• a network board associated with each indoor unit of the hot/cold air/air heat pump system to remote control operation of the associated indoor unit;
• an electronic electrical power meter connected to the photovoltaic system, the electrical appliances in the closed environment, and public electrical power mains to measure electrical power production of the photovoltaic system and electrical power absorbed from, or supplied to, the public electrical power mains as a result of an electrical power underproduction or overproduction of the photovoltaic system with respect to the electrical power consumption of the electrical appliances in the closed environment;
• and
• an electronic control unit connected to the (chrono)thermostats of the water boiler, the network boards of the indoor units of the hot/cold air/air heat pump system, and the electronic electrical power meter, provided with a display through which a user can interact with the joint water boiler-air/air heat pump an conditioning system, and programmed to manage the joint water boiler-air/air heat pump air conditioning system based on the electrical power production of the photovoltaic system;
• the electronic control unit being programmed to:
• allow operating modes to be selected and operation of the joint water boiler-air/air heat pump air conditioning system to be programmed, and information on the operation of the joint water boiler-air/air heat pump air conditioning system to be displayed on the display;
• allow switch on/off priorities and temperatures of the indoor units of the hot/cold air/air heat pump system to be programmed,
• receive data from the (chrono)thermostats of the water boiler, the network boards of the indoor units of the hot/cold air/air heat pump system, and the electronic electrical power meter;
• compute, based on the received data, electrical power production of the photovoltaic system and electrical power consumption of the electrical appliances in the closed environment and, based thereon, electrical power production of the photovoltaic system in surplus of the electrical power consumption of the electrical appliances in the closed environment;
• and
• when a surplus of electrical power production of the photovoltaic system with respect to the electrical power consumption of the electrical appliances in the closed environment is determined to exist, switch on the indoor units of the hot/cold air/air heat pump system based on the surplus of electrical power production of the photovoltaic system with respect to the electrical power consumption of the electrical appliances in the closed environment.
