[0022] like Figure 1 As shown in this embodiment, an integrated heat pump air conditioning power line carrier system includes a main unit 110, an indoor unit 120, and a thermostat 130. The main unit 110 is equipped with a main control board 111, and also includes a photovoltaic control board 112 and an inverter 113. The main control board 111, the photovoltaic control board 112, and the inverter 113 communicate with each other via power line carrier.

[0023] In this embodiment, communication is achieved via power line carrier, eliminating the need for laying communication lines and reducing system costs.

[0024] Power line carrier communication is a communication method unique to power systems. It is a technology that uses existing power lines to transmit analog or digital signals at high speed via carrier waves.

[0025] In this embodiment, the host 110 may specifically be an outdoor air conditioning host unit that integrates a heat pump air conditioning power line carrier system.

[0026] In this embodiment, the heat pump air conditioner utilizes solar energy as a heat source and coolant, producing no combustion, no smoke, no waste, and no pollution. It is a clean and environmentally friendly technology that utilizes renewable resources. Furthermore, this integrated heat pump air conditioner has three functions: cooling, heating, and hot water production.

[0027] In this embodiment, the air conditioner can be powered by photovoltaic power or mains power.

[0028] In this embodiment, the indoor unit 120 is provided with an indoor unit control board 121, and the main control board 111, the photovoltaic control board 112, the inverter 113, the indoor unit control board 121 and the thermostat 130 communicate with each other via power line carrier.

[0029] In this embodiment, the photovoltaic control board 112 and the inverter 113 are located inside the host unit.

[0030] In this embodiment, the system also includes an energy storage battery 170 and an energy storage battery control board 180. The energy storage battery control board 180 communicates with the photovoltaic control board 112, the main control board 111, and the inverter 113 via power line carrier communication. The energy storage battery 170 is electrically connected to the energy storage battery control board 180. The energy storage battery control board 180 is also electrically connected to the main control board 111, the photovoltaic control board 112, and the inverter 113.

[0031] In another embodiment, the photovoltaic control board 112 and the inverter 113 can also be housed within the energy storage battery module, such as... Figure 1 As shown, the energy storage battery 170 and the energy storage battery control board 180 constitute an energy storage battery module. The energy storage battery control board 180 is electrically connected to the photovoltaic control board 112 and the inverter 113.

[0032] In this embodiment, a solar panel 160 is also included. The solar panel 160 is electrically connected to the photovoltaic control board 112. The solar panel 160 absorbs sunlight to generate electricity and outputs direct current.

[0033] In this embodiment, the solar panel 160 and the photovoltaic control panel 112 communicate via power line carrier.

[0034] In this embodiment, the host 110 is also provided with an AC / DC module 114, which is connected to the mains power. In this air conditioning system, the AC / DC module 114 is specifically an AC / DC conversion module, which is used to convert the AC power (AC) input from the mains power grid into the DC power (DC) required by the various electronic components inside the air conditioner, so as to ensure the stable operation of the air conditioning system.

[0035] In this embodiment, the AC / DC module 114 is electrically connected to the inverter 113. The inverter 113 converts the DC power from the solar panel 160 into AC power to power the air conditioner. When the AC / DC module 114 is connected to the mains power grid, it converts the AC power input from the mains into DC power. When the air conditioner compressor is an AC inverter compressor, the AC / DC module 114 inputs DC power to the inverter 113, and the inverter 113 outputs inverter AC power to drive the air conditioner compressor. Specifically, the AC mains power (usually 220V) is first converted into approximately 310V DC power by the AC / DC module 114. This DC power is then connected to the inverter 113, which converts the 310V DC power into frequency-adjustable AC power to drive the compressor motor, achieving speed regulation and energy saving, thus realizing the inverter operation of the outdoor unit compressor.

[0036] In this embodiment, when solar energy is insufficient, if the air conditioner is a fixed-frequency air conditioner, the air conditioner can be directly connected to the mains power supply, and the air conditioner can be directly supplied with AC power such as 220V to allow the air conditioner to operate at a fixed frequency. At this time, the AC / DC module 114 rectifies, filters and stabilizes the 220V mains power and outputs 12V or 5V low-voltage DC power to supply power to the indicator lights and other devices in the outdoor unit 110 of the air conditioning system.

[0037] In this embodiment, the thermostat 130 is electrically connected to the indoor unit control board 121. The thermostat 130 can control the operation of the ducted air conditioner via the indoor unit control board 121 by outputting commands, such as controlling changes in the fan speed. And / or, the thermostat 130 can be electrically connected to the main control board; when the thermostat 130 sends a command, the main control board 111 can be used to change the air conditioner's operating mode, such as the on / off status of the air conditioner.

[0038] In this embodiment, a hydraulic module 150 is also included, which includes a hydraulic module control board (not shown in the figure). The hydraulic module control board is electrically connected to the main control board 111, and the hydraulic module control board and the main control board 111 communicate via power line carrier. Alternatively, the hydraulic module is electrically connected to a thermostat, and the hydraulic module control board is electrically connected to the thermostat 130. The hydraulic module control board and the thermostat 130 communicate via power line carrier, and the thermostat can control the operation of the hydraulic module control board within the hydraulic module.

[0039] In this embodiment, the hydraulic module 150 is equipped with a buffer tank, an expansion tank, and a water pump. The hydraulic module 150 facilitates pressure relief for the entire air conditioning system, and the hot water in the buffer tank provides heat to the air conditioning system during winter defrosting mode operation, preventing any impact on the user experience. The main control board 111 can send commands to the hydraulic module control board. Electrical components in the hydraulic module, such as the water pump, are electrically connected to the hydraulic module control board, thereby controlling the start and stop of the water pump and other equipment in the hydraulic module 150. The hydraulic module control board communicates with the main control board 111 via power line communication, allowing the main control board 111 to quickly obtain status changes of the equipment in the hydraulic module 150.

[0040] In this embodiment, a hot water module 140 is also included. The hot water module 140 includes a hot water module control board (not shown in the figure). The hot water module control board is electrically connected to the main control board 111, and the hot water module control board and the main control board 111 communicate with each other via power line carrier. And / or, the hot water module is electrically connected to a thermostat, and the hot water module control board is electrically connected to the thermostat 130, and the hot water module control board and the thermostat 130 communicate with each other via power line carrier. The operation of the hot water module control board in the hot water module can be controlled by the thermostat.

[0041] like Figure 2 As shown, in this embodiment, the hot water module 140 includes a heat exchanger 141, a hot water tank 142, and a temperature sensor 143. The heat exchanger 141 is connected to the hot water tank 142, and the temperature sensor 143 is located between the heat exchanger 141 and the hot water tank 142.

[0042] In this embodiment, the heat exchanger 141 can be a shell-and-tube heat exchanger or a plate heat exchanger. The heat exchanger 141 is connected to the hot water tank 142 via a pipeline. Specifically, the inlet of the heat exchanger 141 is connected to the outlet of the hot water tank 142 via a pipeline, and the outlet of the heat exchanger 141 is connected to the inlet of the hot water tank 142 via a pipeline. By setting up the hot water module 140, when the integrated heat pump air conditioner is running in summer cooling mode, the waste heat that would otherwise be discharged outdoors is exchanged with the water in the heat exchanger 141, thus enabling the waste heat to be reused and the heated hot water to provide users with hot water for bathing. The main control board 111 can send commands to the hot water module control board in the hot water module. The electrical components in the hot water module are electrically connected to the hot water module control board, and the operation of the hot water module control board is controlled by the main control board.

[0043] In this embodiment, the main control board 111 is electrically connected to the temperature sensor 143 and communicates via power line carrier. The main control board 111 can detect the inlet and outlet temperatures of the heat exchanger 141 through the temperature sensor 143, thereby controlling whether the required hot water temperature for the user has been reached. The temperature sensor 143 can also be installed inside the hot water tank 142. The main control board 111 can also detect changes in the water temperature in the hot water tank 142 through the temperature sensor 143. When the water temperature reaches the user's requirement, the main control board 111 controls the operation mode of the integrated heat pump air conditioner to switch or controls the integrated heat pump air conditioner to shut down. If the water temperature in the hot water tank 142 reaches the set temperature, the recovery of waste heat will stop.

[0044] In this embodiment, a water pump can also be installed in the hot water module 140. The water pump is located on the pipe between the outlet of the hot water tank 142 and the inlet of the heat exchanger 141, so that the water in the hot water tank 142 can quickly enter the heat exchanger 141. The water pump can be electrically connected to the main control board 111 and communicate with it via power line carrier, so that the main control board 111 can control the operation of the water pump.

[0045] In this embodiment, there may be multiple indoor units 120, and the indoor unit control boards 121 of the multiple indoor units 120 communicate with each other via power line carrier. The specific number of indoor units 120 can correspond to the number of rooms occupied by the user.
