Technical Field
[0001] This utility model relates to the field of solar thermal air conditioning technology, specifically to a solar thermal central air conditioning system. Background Technology
[0002] In some remote mountainous areas, islands, border outposts, and desert hinterlands, where there is no access to the mains power grid, but solar energy is relatively abundant, people usually use solar energy to provide electricity. However, the limited amount of electricity converted is mostly used to solve daily lighting or office power needs, especially in winter when it cannot power household air conditioners, thus failing to provide a comfortable living or working environment.
[0003] Therefore, researching and developing a solar thermal central air conditioning system that fully utilizes solar energy resources, has a simple structure, and is reliable in operation is key to solving this problem. Utility Model Content
[0004] This utility model provides a solar thermal central air conditioner that can make full use of the sun's light and heat to realize the cooling and heating functions of the indoor unit, thus meeting the needs of some remote mountainous areas, islands, border outposts, desert hinterlands and other scenarios without access to the mains power.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a solar thermal central air conditioning system, comprising: a solar heater, the solar heater having an inlet pipe and an outlet pipe, and a first electrically controlled valve disposed on the inlet pipe and the outlet pipe; a photovoltaic panel, the photovoltaic panel having a power supply terminal; a cooler, the cooler having an inlet pipe and an outlet pipe, and a second electrically controlled valve disposed on the inlet pipe and the outlet pipe; an indoor unit, the indoor unit having an inlet pipe and an outlet pipe, and a third electrically controlled valve disposed on the inlet pipe and the outlet pipe; the solar heater, the cooler, and the indoor unit are respectively connected in parallel through a circulation pipeline, and the circulation pipeline is equipped with a circulation pump; an indoor controller, the indoor unit and the third electrically controlled valve are respectively electrically connected to the indoor controller; a main controller, the indoor controller, the photovoltaic panel, the cooler, the first electrically controlled valve, the second electrically controlled valve, and the circulation pump are respectively electrically connected to the main controller.
[0006] Preferably, it also includes an electric heater, which has a heating coil inside and an electric heating wire wound around the outside of the heating coil. The liquid inlet and liquid outlet of the heating coil are connected in parallel with the circulation pipeline through a fourth electric control valve. The electric heating wire is electrically connected to the main controller.
[0007] Preferably, the cooler includes a thermoelectric cooler and a cooling coil attached to the bottom of the thermoelectric cooler, the cooling coil being connected in parallel with the circulation pipeline via the second electrically controlled valve; a heat sink is provided on the top of the thermoelectric cooler, the heat sink being electrically connected to the main controller.
[0008] Preferably, the outlet pipe of the solar heater is equipped with a temperature sensor, which is electrically connected to the main controller.
[0009] Preferably, there are multiple indoor units, and each indoor unit and each of the third electronically controlled valves are electrically connected to the indoor controller.
[0010] The beneficial effects of this invention are as follows: This air conditioner can fully utilize the sun's light and heat to achieve both cooling and heating functions in the indoor unit, thus meeting the needs of remote mountainous areas, islands, border outposts, and desert regions without mains power. During operation, the user controls the air conditioner through the indoor controller. When cooling is activated, the main controller receives the cooling command from the indoor controller, closes the first solenoid valve, opens the second and third solenoid valves, starts the circulation pump, and coordinates the operation of the radiator and semiconductor cooling chip. At this time, the liquid in the circulation pipe circulates between the cooling coil and the indoor unit, achieving heat exchange and causing the indoor unit to blow out cold air to achieve a cooling effect. When heating mode is activated, the main controller opens the first and third solenoid valves and closes the second solenoid valve. At this time, the liquid in the circulation pipe circulates between the solar heater and the indoor unit. Under the sun's radiation, the solar heater heats the liquid in the circulation pipe, thus putting the indoor unit into heating mode. The electric heater obtains its operating current through the photovoltaic panel, thereby assisting the solar heater in meeting the heating needs of the indoor unit at night. The temperature sensor collects the heating efficiency of the solar heater. When the solar heater cannot meet the heating requirements, the main controller opens the fourth electric control valve and simultaneously supplies power to the heating wire to heat the heating coil, so that the liquid in the circulation pipeline meets the heating requirements.

The indoor units 6 are multiple, and each indoor unit 6 and each of the third electronically controlled valves 7 are electrically connected to the indoor controller 10. The cooler includes a thermoelectric cooler 15 and a cooling coil 16 attached to the bottom of the thermoelectric cooler 15.

[0016] Through the above design, this air conditioner can fully utilize the sun's light and heat to achieve the cooling and heating functions of the indoor unit 6, thus meeting the needs of remote mountainous areas, islands, border outposts, and desert areas without access to mains power. During operation, the user controls the air conditioner through the indoor controller 10. When cooling is activated, the main controller 11 receives the cooling command from the indoor controller 10, closes the first electronic control valve 2, opens the second electronic control valve 5 and the third electronic control valve 7, starts the circulation pump 9, and coordinates the operation of the radiator 17 and the semiconductor cooling chip 15. At this time, the liquid in the circulation pipe 8 circulates between the cooling coil 16 and the indoor unit 6, achieving heat exchange and causing the indoor unit 6 to blow out cold air to achieve a cooling effect. When heating mode is activated, the main controller 11 opens the first electronic control valve 2 and the third electronic control valve 7, and closes the second electronic control valve 5.

[0018] In this setup, the electric heater obtains its operating current through the photovoltaic panel 3, thereby assisting the solar heater 1 in meeting the heating needs of the indoor unit 6 at night.
[0019] The outlet pipe of the solar heater 1 is equipped with a temperature sensor 18, which is electrically connected to the main controller 11.
[0020] Through this setting, the temperature sensor 18 collects the heating efficiency of the solar heater 1. When the solar heater 1 cannot meet the heating requirements, the main controller 11 opens the fourth electric control valve 14 and simultaneously supplies power to the electric heating wire 13 to heat the heating coil 12, so that the liquid in the circulation pipe 8 meets the heating requirements.
