In this embodiment, the current heat load corresponding to the target fan coil may be obtained first, where the current heat load is the heat absorbed by the hot air blown by the target fan coil in unit time.
Then, based on the current heat load and the required heat load, a total heat load corresponding to the target fan coil is determined, for example, for a fan coil with a set temperature greater than or equal to the air-out temperature in the target fan coil, the total heat load is the sum of the current heat load and the required heat load, and for a fan coil with a set temperature less than the air-out temperature in the target fan coil, the total heat load is the difference between the current heat load and the required heat load.
