Self-adaptive control method, device and system for integrated fan coil

The invention provides a self-adaptive control method, device and system for an integrated fan coil. The method comprises the following steps: switching a unit to a constant-temperature comfortable energy-saving mode for operation; the self-adaptive integrated controller obtains a temperature difference value between the current indoor temperature and the indoor preset temperature; when the temperature difference value is smaller than or equal to a first preset value, the self-adaptive integrated controller controls the fan to operate at the minimum wind speed parameter and controls the electric valve to keep the current working state; when the second preset value is larger than the temperature difference value and the temperature difference value is larger than the first preset value, the self-adaptive integrated controller controls the draught fan to operate at the minimum air speed parameter, and the electric valve is dynamically adjusted to operate; and when the temperature difference value is larger than
