In order to provide a better understanding of the energy delivery system of the present application, it will be further explained and illustrated below. As shown in fig. 1 and 2, the energy supply system may include: an air conditioner external unit 1, an energy supply device 2, and a central control unit 3. The air conditioner external 1 may include a compressor 11, a first heat exchange unit 12, and a first control unit 13. The compressor 11 compresses the refrigerant returned from the power supply device 2 to the air conditioner outdoor unit 1. The compressor 11 may employ a variable frequency compressor 11. The first heat exchange unit 12 acts as a condenser when the energy supply system is in cooling operation and the first heat exchange unit 12 acts as an evaporator when the energy supply system is in heating operation. The first control unit 13 is configured to control the air conditioner external unit 1 and collect a first parameter of the air conditioner external unit 1, for example, parameters such as operating power, frequency, etc. of the compressor 11.
The energy supply device 2 exchanges refrigerant with the air-conditioning external unit 1, and the energy supply device 2 receives the refrigerant output from the air-conditioning external unit 1 and outputs the used refrigerant back to the air-conditioning external unit 1. As shown in fig. 2, the energy supply device 2 may comprise a second control unit 21 for acquiring a second parameter of the energy supply device 2. Further, the second control unit 21 may control the energy supply device 2 correspondingly.
As a possible implementation, fig. 3 is a schematic structural diagram of the energy supply device according to the first embodiment of the present utility model, and as shown in fig. 3, the energy supply device 2 may include: the second heat exchange unit 24, the second heat exchange unit 24 has a first heat exchange flow path 241 and a second heat exchange flow path 242 capable of performing heat exchange. Both ends of the first heat exchanging flow path 241 are respectively communicated with the air conditioner external unit 1. The second heat exchange unit 24 acquires the cold or heat input to the energy supply device 2 by the air conditioner external unit 1 through the refrigerant, and transmits the part of the cold or heat to the terminal device 6 through the working medium flowing through the second heat exchange flow passage 242.
As shown in fig. 1 and 2, the central control unit 3 is a control module independent of the air conditioner external unit 1 and the energy supply device 2. The central control unit 3 is capable of data communication with a second control unit 21 in the at least one energy supply device 2. Meanwhile, the central control unit 3 can perform data communication with the first control unit 13 in the at least one air conditioner external unit 1, and of course, the central control unit 3 can perform data communication with the first control unit 13 through the second control unit 21, that is, the first control unit 13 and the second control unit 21 can perform data communication, so that the first control unit 13 performs data communication with the central control unit 3 indirectly through the second control unit 21. In this way, it is avoided that the first control unit 13 communicates data directly with the central control unit 3, which requires the provision of more complex communication lines.
As a possible, the energy supply system may include: home appliance local communication network in which the first control unit 13 and/or the second control unit 21 performs data communication with the central control unit 3 via the home appliance local communication network. The central control unit 3 may be installed together with the air conditioner external unit 1 and the energy supply device 2 at a user location where the energy supply system is located, and may not be a control unit located at the cloud, so that safety of data and control of the energy supply system of the user may be ensured. Correspondingly, the home appliance local communication network can realize that the first control unit 13 and/or the second control unit 21 perform local data communication with the central control unit 3 so as to ensure the safety of data communication. The first control unit 13 and/or the second control unit 21 perform data communication with the central control unit 3 through a home appliance local communication network in a wired manner or a wireless manner.
In other possible embodiments, the first control unit 13 and/or the second control unit 21 may also be in data communication with the central control unit 3 via power line communication.

The second control unit 21 is adapted to send the second parameter of the harvested energy supply device 2 to the central control unit 3. The central control unit 3 is configured to receive the first parameter of the air conditioner external unit 1 and/or the second parameter of the energy supply device 2 sent by the second control unit 21, which are sent by the first control unit 13, and the central control unit 3 determines whether an anti-freezing operation is required according to the first parameter and the second parameter, and if so, generates a first command for anti-freezing, and sends the first command to the first control unit 13. The first control unit 13 is configured to receive the first instruction and control the air conditioner external unit 1 to execute the first instruction. The first parameter of the air conditioner external unit 1 transmitted by the first control unit 13 may be directly transmitted to the central control unit 3, or may be forwarded to the central control unit 3 through the second control unit 21 of the energy supply device 2. The first command for preventing freezing can be sent directly to the first control unit 13 of the external air conditioner 1 or can be forwarded to the first control unit 13 of the external air conditioner 1 by the second control unit 21 of the energy supply device 2.
Since the central control unit 3 is an additional control module independent of the air conditioner external unit 1 and the energy supply device 2, parameters of the whole energy supply system can be collected, and the anti-freezing control logic of the whole energy supply system can be controlled by the central control unit 3 through self-setting, so that the anti-freezing control of the whole energy supply system can be more reasonable and effective. In addition, since the central control unit 3 realizes the antifreeze control for the entire energy supply system, any model and brand of the air conditioner external unit 1 may be adopted in the energy supply system, and it is unnecessary to consider that the model and brand of the air conditioner external unit 1 must be the same as the energy supply device 2. Finally, the anti-freezing control function of the central control unit 3 and the anti-freezing control function of the first control unit 13 of the air conditioner external unit 1 can be owned at the same time, and the two functions do not conflict, so that the whole energy supply system can have double guarantee for anti-freezing control.
As a possible one, the energy supply system may include a throttle unit 4 for throttling the refrigerant compressed by the compressor 11, as shown in fig. 3, and the throttle unit 4 may be provided in the air conditioner external unit 1 or the energy supply device 2. Correspondingly, the energy supply system may comprise a pressure detection unit 5 for measuring the pressure of the refrigerant upstream of the inlet of the compressor 11 after throttling by the throttling unit 4. The pressure detection unit 5 may be provided in the energy supply device 2 or in the air conditioner external unit 1.
When the pressure detecting unit 5 is disposed in the air conditioner external unit 1, the pressure detecting unit 5 is electrically connected with the first control unit 13, and the first parameter may include: the pressure of the refrigerant throttled by the throttle unit 4.

For example, the central control unit 3 may generate the first command for freezing prevention according to the flow rate of the working medium exchanging heat with the refrigerant and/or the temperature of the working medium exchanging heat with the refrigerant and/or the pressure of the refrigerant throttled by the throttle unit 4, etc., and the generating the first command for freezing prevention may include one of the following: down-conversion of the compressor, shutdown actions, etc. The central control unit 3 sends it to the first control unit; the first control unit receives the first instruction and controls the air conditioner external unit to execute the first instruction.

When the energy supply system is in a heating state, the heat supply unit 25 can further heat the working medium in the second flow passage 29 after being heated by the second heat exchange unit 24, thereby increasing the temperature of the working medium delivered to the terminal device 6.
