Background
The fan coil is usually controlled in situ by an indoor temperature controller and an electric valve, and aims to keep the indoor temperature constant and save energy consumption, but the in situ control mode is not desirable, because the in situ control mode is usually because users in each air conditioning area do not know the air conditioning control principle and have low energy-saving consciousness, the controller cannot achieve the expected energy-saving aim.
It is known that most of fan coil controllers control the opening and closing of valves on water pipes according to a set temperature value, and the high, medium and low three-gear wind speeds of fans are set manually instead of automatically adjusting the speed along with the change of temperature difference, so that the loss of electric quantity of the fans is caused. In addition, after people enter a room, the set value of the controller is always adjusted to be very low or very high for quick cooling or quick heating, but the set value is not restored to the normal set value after the temperature reaches too low or too high, so that a large amount of energy consumption is caused. If the people are slightly less conscious of energy conservation, and the window is opened to dissipate heat when the people are too cold or too hot, the energy consumption is more remarkable.

The automatic control unit 27 can sense the current indoor state in real time, then automatically control the electromagnetic valve of the fan coil according to the strategy, realize the functions of automatic adjustment and automatic control, and the system can sense whether a person is in the room by matching with a proper sensor, and automatically close the tail end fan coil under the unmanned condition according to the control strategy, thereby saving energy.
According to the invention, due to the arrangement of the metering unit 210, the running time and the state of each gear of large, medium and small of each room can be measured in real time, the main control unit 21 can also measure the running conditions of all the states of all the fans, the real use condition of the air conditioners in each room can be measured through a networking intelligent algorithm, various unreasonable factors for distributing the energy of the air conditioners according to the area are avoided, an accurate and effective tool is provided for energy consumption management, the networking metering function of the air conditioners is realized, the use condition of the air conditioners in each room can be counted, the air conditioners are decomposed into each room according to the total energy of the air conditioners, the energy consumption of the air conditioners is counted according to the.
The invention can realize the real-time monitoring of the remote state of each fan, can remotely check the state, the operating gear, the mode, the timing condition, the set temperature and the current temperature of the central air conditioner, can remotely control each wind control panel through a network, and can realize the remote setting of the gear, the temperature, the mode, the timing and the like of the fan, when going off duty, a manager can close the air conditioner which is forgotten to be closed by office personnel through the function, thereby realizing the purpose of managing and saving energy, when going on duty, the manager can remotely check whether each office regulates the air conditioner at the proper temperature according to the regulation, if not, the manager can remotely regulate the air conditioner, thereby achieving the purpose of saving energy.
The invention can issue a remote hosting command through a network, and in a remote hosting state, the air conditioner panel is controlled by a remote computer host, and the air conditioner panel is not subjected to local key operation, so that the function provides good management support for building management, if the temperature of the air conditioner in summer is regulated to be not lower than 26 ℃ and the temperature of the air conditioner in winter is regulated to be not higher than 20 ℃, under the existing condition, a manager cannot control the air conditioner, but after the remote hosting is started, the air conditioner user cannot directly adjust parameters such as temperature and mode through the panel, and only can receive remote command control, so that energy conservation can be well realized.
