Abstract

The invention provides a multi-connected air conditioner hot-water unit. The multi-connected air conditioner hot-water unit comprises an outdoor unit and a plurality of indoor units. The multi-connected air conditioner hot-water unit further comprises a communication bus connected with the outdoor unit and the multiple indoor units. Accordingly, the multi-connected air conditioner hot-water unit is connected into a network of a bus structure. Due to the fact that the communication among the outdoor unit and the multiple indoor units is allowed by the communication bus, the communication among the multiple indoor units is also allowed by the communication bus at the same time, thus the mutual communication among all the indoor units can be achieved by the multi-connected air conditioner hot-water unit, and all the parts can be well matched with each other to operate.

Description

technical field

[0001] The present application relates to the technical field of air conditioning, and more specifically, relates to a multi-connected air conditioning and hot water unit. Background technique

[0002] At present, multi-connected air-conditioning and hot water units are widely used because of energy saving and environmental protection. The multi-connected air-conditioning and hot water unit is composed of an outdoor unit and an indoor unit. The outdoor unit is an air-conditioning outdoor unit, and the indoor unit includes an air-conditioning indoor air conditioner and a hot water generator connected to the outdoor unit. The communication connection between the outdoor unit and each indoor unit of the current multi-connected air-conditioning and hot water unit is realized through the communication network based on the RS485 protocol, because the communication mechanism of the RS485 protocol adopts the master-slave mode, that is, the outdoor unit cyclically cal...

Examples

Embodiment 1

[0031] figure 1 It is a structural diagram of a multi-connected air conditioner and hot water unit provided in the embodiment of this application.

[0032] Such as figure 1 As shown, the multi-connected air conditioner and hot water unit provided in this embodiment includes an outdoor unit 10 , multiple indoor units 20 and a communication bus 30 .

[0033] Wherein the outdoor unit 10 is an outdoor unit located outdoors, and the multiple 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 the communication bus 30 or receive data from the communication bus 30, and a plurality of 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 (Controll...

Embodiment 2

[0044] Figure 4 It is a structural diagram of a multi-connected air conditioner and hot water unit provided in another embodiment of the present application.

[0045] Such as Figure 4 As shown, the multi-connected air-conditioning and hot water unit provided in this embodiment is based on the previous embodiment with an additional floor heating valve and a floor heating heater (not shown). The floor heating valve is used to connect the hot water generator 22 with the floor heating Coil (not shown). The floor heating valve 24 is connected with the CAN bus 31 .

[0046]Set the network address correspondence between the indoor air conditioner A and the floor heating valve A through the water heater wire controller (not shown), where both are installed in room A, and set the network address correspondence between the indoor air conditioner B and the floor heating valve B, where both are installed In room B, by receiving the information of indoor air conditioner A and indoor a...

Embodiment 3

[0051] Figure 5 A structural diagram of a multi-connected air-conditioning water heater group provided for another embodiment of the present application.

[0052] Such as Figure 5 As shown, the multi-connected air-conditioning and hot water unit provided in this embodiment is based on the previous embodiment with the addition of a solar water heating device 50 .

[0053] The solar water heating device 50 communicates with the hot water generator 22, and is connected with the CAN bus 31 signal, for utilizing solar energy to obtain hot water and correspondingly replenishing the hot water generator 22, while being connected through the CAN bus 22 can Ensure that it works under unified control and coordination.

[0054] In order to ensure the normal operation of the solar water heating device 50, an electric heater (not shown) can be added in the solar water heating device 50 to protect the safety when working in a low temperature area and avoid being damaged by freezing and c...
