[0038] Furthermore, each indoor environment controller 15 corresponds to a variable air volume air valve 16.

[0039] Furthermore, one all-air air handling unit 17 is connected to multiple indoor environment controllers 15.

[0040] Furthermore, one air source heat pump host 18 is connected to multiple all-air air handling units 17.

[0041] Furthermore, the indoor environment controller 15 communicates with the all-air air handling unit 17, the air source heat pump host 18 and the gateway 22 in a daisy chain manner using communication lines.

[0042] As an example, the indoor environment controller 15 controls the floor heating using weak electric signals, and the control line is connected to the floor heating centralized controller 19, and the floor heating thermoelectric valve 20 of each floor heating circuit is controlled by outputting strong electric signals through the floor heating centralized controller 19.

[0047] When the indoor environment controller 15 turns on the floor heating + heating + fresh air mode, the all-air air handling unit 17 operates, the air source heat pump host 18 starts to provide heat source to the all-air air handling unit 17 and the floor heating manifold 21, the variable air volume damper 16 automatically adjusts the opening of the variable air volume damper 16 according to the change of indoor load monitored by the indoor environment controller 15, and operates with automatic variable air volume. The indoor environment controller 15 outputs signals to the floor heating central controller 19 by monitoring the change of indoor load to automatically adjust the opening and closing of the floor heating thermoelectric valve 20 of each floor heating circuit.

[0048] When the indoor environment controller 15 turns on the fresh air mode, the all-air air handling unit 17 operates, the variable air volume damper 16 is fully opened, and the air source heat pump host 18 does not start.

[0049] When the indoor environment controller 15 turns on the dehumidification mode + fresh air mode, the all-air air handling unit 17 operates, the air source heat pump host 18 starts to provide cold source to the all-air air handling unit 17, and the variable air volume damper 16 automatically adjusts the opening of the variable air volume damper 16 according to the change of indoor load monitored by the indoor environment controller 15, and operates with automatic variable air volume.
