The water supply pipe 1a and the collecting pipe 5a can be connected through the differential pressure bypass valve 7a, so that the water in the shunt pipe 2a can smoothly flow into the collecting pipe 5a when the fan coil 3a and the heat exchanger 61a in the air conditioning unit 6a are not operated. Of course, the water storage unit 8a can be connected with the radiation coil 9a through the water pump 10a according to the self requirement, so that the air conditioning system can realize the function of floor heating. As can be seen from the above, the air conditioning system has a large number of three-way connectors to be connected on site when being installed on site, so that the water supply pipe 1a and the collecting pipe 5a are connected with the shunt pipe 2a, the electric on-off valve 4a and the like through the three-way connectors, thereby causing the inefficiency of operators when being installed on site and the risk of connection errors; in addition, the three-way joint is difficult to ensure the tightness after being installed on site, leakage can occur in the later stage, and particularly the three-way joint is installed in a suspended ceiling, and is difficult to find and maintain in the later stage.

When the on-off valves 6 in all the first fan coil units 2 are disconnected, and all the first fan coil units 2 are not used, and the second fan coil units 3 are not used, the three-way valve 5 can be switched to the third water supply pipe interface 31, and the third water return pipe interface 32 is communicated through the three-way valve 5 and the return pipe 34, so that water output by the fan coil water supply pipe interface 16 of the air conditioning unit 1 can be guaranteed to flow back to the fan coil water return pipe interface 17 through the return pipe 34 under the condition. Typically, the second fan coil apparatus 3 is located at the far end relative to the first fan coil apparatus 2.

When the first fan coil units 2 are multiple, the third water supply pipe joint 31 is connected with the second water supply pipe joint 22 of the last first fan coil unit 2 through a pipeline, and the third water return pipe joint 32 is connected with the second water return pipe joint 24 of the last first fan coil unit 2 through a pipeline;

the second water supply pipe joint 22 of the first fan coil unit 2 is connected with the first water supply pipe joint 21 of the second first fan coil unit 2; the second return line connection 24 of the first fan coil unit 2 is connected to the first return line connection 23 of the second first fan coil unit 2 and so on.

The number of the second fan coil units 3 may be one or more. When the number of the second fan coil units 3 is plural, the plurality of the second fan coil units 3 only need to be connected with the fan coil water supply pipe interface and the fan coil water return pipe interface of the air conditioning unit in a parallel connection mode. When the number of the first fan coil units 2 is plural, the plurality of first fan coil units 2 may be connected with the fan coil water supply pipe interface and the fan coil water return pipe interface of the air conditioning unit only by a parallel connection mode. The plurality of second fan coil units may be located at the distal-most ends in different directions, respectively.

When the fan coil units are two or more, the upper fan coil water supply pipe joint 16 and the fan coil return pipe joint 17 of the air conditioning unit 1 can be connected to the first water supply pipe joint 21 and the first return pipe joint 23 of the first fan coil unit 2 through two pipelines, respectively. When the fan coil water supply pipe interface 16 and the fan coil water return pipe interface 17 on the air conditioning unit 1 need to be connected with the second first fan coil device 2 or the second fan coil device 3, only the second water supply pipe interface 22 of the first fan coil device 2 needs to be connected with the first water supply pipe interface 21 of the second first fan coil device 2; the second return pipe connection 24 of the first fan coil unit 2 is connected with the first return pipe connection 23 of the second first fan coil unit 2; alternatively, the second water supply pipe connection 22 of the first fan coil unit 2 is connected to the third water supply pipe connection 31 of the second fan coil unit 3 by a pipeline, and the second water return pipe connection 24 of the first fan coil unit 2 is connected to the third water return pipe connection 32 of the second fan coil unit 3 by a pipeline. All devices in the whole air conditioning system are connected through point-to-point linear pipelines, any three-way connector is not needed, so that the efficiency of operators in field installation can be greatly improved, and the risk of connection errors is not easy to occur. In addition, the devices are connected through straight pipelines, and other connecting points are not existed in the devices, so that the tightness of the devices can be ensured during field installation, and leakage can not occur basically in the later stage; even if leakage occurs, the leakage can only occur at the joint of the pipeline and the device, and the device can be directly maintained at the installation port or the maintenance port because the installation port or the maintenance port is arranged when the device is installed.
