In rainy plum seasons, the indoor space basically has no sensible heat load, the fan coil 9 is linked with the indoor temperature, and the tail end of the fan coil 9 is basically not required to be started for refrigeration.
In one embodiment, the operating mode of the transition seasonal system is: transition season, fan coil 9 and the terminal 6 in the off-state of floor heating, air conditioner host 1 closes, and heat pipe formula fresh air unit 3 adopts the ventilation mode, and under this mode, only the fan is opened, plays the effect that the ventilation blower removed the haze.
In one embodiment, the combined operation logic of the floor heating and the fresh air in winter is as follows: as shown in fig. 8, when the system is turned on, the fan coil 9 is preferentially operated when the indoor temperature is lower than the set temperature, and the temperature of the room 10 is rapidly raised. And when the indoor temperature Tmax reaches 24 ℃, closing the tail end of the air disc and starting the ground heating tail end. And for single running time, if the running time cannot reach 24 ℃ within 20min, closing the tail end of the air disc and starting the floor heating tail end after the air disc runs for 20 min. Due to the problem of thermal inertia of floor heating operation, the indoor temperature is gradually reduced, and when the Tmax is less than or equal to 16 ℃, the fan coil 9 is started, and the floor heating terminal 6 is closed. The process is repeated, and the Tmax is continuously satisfied and is more than 16 ℃, and the ground heating terminal continuously operates.
It should be noted that the above embodiments can be freely combined as necessary. The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
