[0030] Example one
[0031] figure 1 This is a structural diagram of a multi-connected air-conditioning and hot water unit provided in an embodiment of this application.
[0032] Such as figure 1 As shown, the multi-connected air conditioning and hot water unit provided in this embodiment includes an outdoor unit 10, a plurality of indoor units 20, and a communication bus 30.
[0033] The outdoor unit 10 is an outdoor unit located outdoors, and the plurality of indoor units 20 include at least one indoor air conditioner 21, a hot water generator 22 and a hot water adapter 23.
[0034] The outdoor unit 10 is connected to the communication bus 30 and can output data to or receive data from the communication bus 30, and multiple indoor units are also respectively connected to the communication bus 30, and can also output data to the bus 30 Or receive data from the communication bus 30.
[0035] The communication bus 30 in this embodiment is preferably a CAN (Controller Area Network, Controller Area Network) bus.
[0036] It can be seen from the above technical solutions that this embodiment provides a multi-connected air-conditioning and hot water unit, which includes an outdoor unit and multiple indoor units, and also includes a communication bus connected to the outdoor unit and the multiple indoor units, thereby connecting The multi-connected air-conditioning and hot water unit is connected to a network with a bus structure. Since the communication bus allows communication between the outdoor unit and multiple indoor units, and also allows communication between multiple indoor units, the multi-connected The air-conditioning water heater group can realize the mutual communication between the indoor units, so as to facilitate the better cooperation of the various parts.
[0037] figure 2 It is a schematic diagram of the linkage communication between the hot water generator and the indoor air conditioner.
[0038] Such as figure 2 As shown, the indoor air conditioner 21 is provided with an indoor air conditioner wire controller 211, which is connected through an HBS (HomeBusSystem, home bus system) network 40; the hot water generator 22 is provided with a hot water generator The wire controller 221 is also connected to the hot water generator 22 through the HBS network 40.
[0039] The hot water generator wire controller 221 communicates with the hot water generator 22 through the HBS network 40, and the room air conditioner wire controller 211 also interacts with the room air conditioner 21 through the HBS network 40 to control the room air conditioner 21 and hot water generation The priority of the hot water generator 22; the hot water generator 22 and the indoor air conditioner 21 exchange information via the CAN network 31; this embodiment preferably has the priority of the indoor air conditioner 21 higher than the priority of the hot water generator 22, that is, the indoor air conditioner 21. When the working capacity of the outdoor unit 10 is insufficient, the hot water generator 22 can control itself to reduce the working intensity when the working capacity of the outdoor unit 10 is insufficient.
[0040] In the design of linkage communication, the corresponding network address of the room air conditioner 21 that is related to the hot water generator 22 is set through the hot water generator wire controller 221, and the room air conditioner wire controller 211 can also be set with the room air conditioner. 21 has the corresponding network addresses of the hot water generator 22 that are related to each other, so that the hot water generator 22 and the indoor air conditioner 21 can be bound to each other, and provide a basis for linkage communication. The instant hot water generator 22 and the room air conditioner 21 can receive and send related data through the corresponding network address, such as the switch status, water tank water temperature, floor heating water temperature, indoor environment temperature, system operation mode, etc., and then pass their own Control logic operation, output the required control information, such as the heating demand signal of the water tank, the on-off signal of the floor heating, the opening and closing signal of the water valve in the system, etc., so as to realize the linkage communication.
[0041] image 3 The schematic diagram of the linkage communication between the hot water generator and the outdoor unit.
[0042] Such as image 3 As shown, the hot water generator 21 receives the relevant data of the indoor air conditioner (not shown), and combines its own control logic operation, and the obtained control information related to the outdoor unit 10 interacts with the outdoor unit 10 through the CAN network 31 . The outdoor unit 10 is based on the received information of the hot water generator 22 and the indoor air conditioner, such as indoor ambient temperature, floor heating water temperature, system on/off, water tank water temperature, internal fan speed, etc., according to its own control logic calculations to obtain Control the control signals of the hot water generator 22 and the room air conditioner 21, such as turning on the electric auxiliary heating of the water tank, the running gear of the water pump, the opening of the electronic expansion valve, the system operation mode, the opening and closing of the refrigerant flow valve, etc., so as to realize the hot water Effective linkage communication between the generator 21 and the outdoor unit 10;
