DETAILED DESCRIPTION

[0020] In order to better understand the purpose, structure and function of the present invention, the specific embodiment of the "universal air water generator for photovoltaic power grid" of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0021] See also Figure 1 In this embodiment, the air water making machine includes a refrigerant compressor 100 connected to the photovoltaic power grid, the refrigerant compressor 100 is connected to the radiator 102 through the main pipeline 101, the radiator 102 is connected to the expansion valve 104 through the first pipeline 103, the expansion valve 104 is connected to the air condenser 105 through the first pipeline 103, the air condenser 105 is connected back to the refrigerant compressor 100 through the main pipeline 101, and a liquid collector 106 is arranged at the bottom of the air condenser 105; the radiator 102 is also connected to a second pipeline 107 connected in parallel with the first pipeline 103, and the second pipeline 107 is also sequentially provided with the expansion valve 104 and the air condenser 106. An air condenser 105, a liquid collector 106 is arranged at the bottom of the air condenser 105; a first solenoid valve 108 is arranged on the first pipeline 103, and a second solenoid valve 109 is arranged on the second pipeline 107 to control the opening and closing of the first pipeline 103 and the second pipeline 107; the refrigerant compressor 100 drives the refrigerant to pass through the radiator 102, and the refrigerant after heat dissipation enters the first pipeline 103 or the second pipeline 107 through the first solenoid valve 108 and the second solenoid valve 109, which can control the air condensers 105 on the first pipeline 103 and the second pipeline 107 to work crosswise to produce water, thereby realizing uninterrupted and efficient acquisition of water resources from the air.

[0022] Specifically, when in use, the first solenoid valve 108 is opened and the second solenoid valve 109 is closed, and the air condenser 105 on the first pipe 107 begins to condense frost. When the frost is condensed enough, the second solenoid valve 109 is opened and the first solenoid valve 108 is closed, and the air condenser 105 on the first pipe 103 begins to melt the frost to produce water, and the air condenser 105 on the second pipe 107 begins to condense frost. When the air condenser 105 on the second pipe 107 is condensed enough, the first solenoid valve 108 is opened and the second solenoid valve 109 is closed, and the air condenser 105 on the second pipe 107 begins to melt the frost. To produce water, the air condenser 105 on the first pipe 107 continues to condense ice and frost; by repeating the above operation, there is no need to shut down the compressor 100 to melt the ice and frost. The air condensers 105 on the first pipe 103 and the second pipe 107 work in turn, one condenses ice and frost while the other melts ice and frost, thereby maintaining a continuous water production process and doubling the efficiency of obtaining water resources from the air; and in this way, the compressor 100 does not need to be started and stopped all the time, thereby increasing the service life of the compressor; and the water maker is powered by an independent photovoltaic power grid, which not only saves energy but also can be applied to many work scenarios.

[0023] More specifically, in some embodiments, frost thickness sensors are provided on the first pipe 103 and the second pipe 107 to detect the condensation thickness of frost on the air condenser 105. The frost thickness sensor is electrically connected to the central controller, and the central controller is electrically connected to the first solenoid valve 108 and the second solenoid valve 109 to control the opening and closing of the first solenoid valve 108 and the second solenoid valve 109; in this way, the system can automatically determine whether the frost thickness of the air condenser 105 on the first pipe 103 or the second pipe 107 reaches a preset value, and then automatically control the opening of the first solenoid valve 108 and the closing of the second solenoid valve 109 or the opening of the second solenoid valve 109 and the closing of the first solenoid valve 108; the automatic switching of condensing and melting frost in the air condenser 105 on the first pipe 103 and the second pipe 107 is realized through system control, so as to realize the automatic and uninterrupted operation of the air water making machine. In other embodiments, the frost thickness sensor can be replaced by a time controller. After the water making machine has been working for a preset time, the time controller controls the closing / opening of the first solenoid valve 108 / the second solenoid valve 109 through the central controller. The system can also be used to control the automatic switching of frost condensation and frost melting of the air condenser 105 on the first pipeline 103 and the second pipeline 107, thereby realizing automatic and uninterrupted operation of the air water making machine.

[0024] See also Figure 1In this embodiment, the radiator 102 includes a metal tube 1021 and a cooling fan 1022. The metal tube 1021 is provided with a heat sink 1023. The refrigerant compressor 100 drives the high-temperature and high-pressure gaseous refrigerant to pass through the metal tube 1021, and conducts heat through the heat sink 1023. The heat sink 1022 blows air toward the heat sink 1023 to cool the refrigerant to a liquid state at a suitable temperature, so that the subsequent expansion valve 104 can cool the liquid refrigerant to a low-temperature gaseous cold source. At the same time, the radiator 102 also includes a refrigerant temperature sensor, which is electrically connected to the central controller. When the refrigerant temperature sensor detects that the refrigerant temperature reaches the set temperature, the central controller controls the opening of the first solenoid valve 108 / the second solenoid valve 109 to realize automatic control and adjustment of the water making machine.

[0025] More specifically, in the present embodiment, a refrigerant filter 110 is provided on both the first pipe 103 and the second pipe 107. The refrigerant filter 110 is provided between the radiator 102 and the expansion valve 104 to filter the refrigerant that will enter the expansion valve 104. The refrigerant filter 110 filters out the micro-metal powder and oil impurities generated by the mechanical friction of the compressor 100, and absorbs the moisture that may be mixed in the refrigerant, thereby ensuring the purity of the refrigerant entering the expansion valve 104 and improving the service life of the expansion valve.

[0026] Furthermore, in this embodiment, the air condenser 105 includes a frost pipe network 1051 and an electric heater 1052. The refrigerant passes through the frost pipe network 1051, and frost condenses on the outer surface of the frost pipe network 1051. The electric heater 1052 melts the frost and drips into the liquid collector 106. Preferably, the frost pipe network 1051 is a three-dimensional mesh structure to increase its contact area with the air and improve the efficiency of condensing frost. In addition, in some embodiments, the air condenser 105 also includes a defrosting fan 1053, which blows air toward the frost pipe network 1051 to accelerate the melting of frost. During the specific installation, the electric heater 1052 and the defrost fan 1053 can be selected to be installed according to different environmental conditions. The water maker can have four defrost modes, one is to let the frost melt automatically, one is to turn on the electric heater 1052 to accelerate the melting of the frost, one is to turn on the defrost fan 1053 to accelerate the melting of the frost, and the last one is to turn on the electric heater 1052 and the defrost fan 1053 at the same time to accelerate the melting of the frost; ensuring that the defrost needs in various usage environments can be met.

[0027] Furthermore, in some embodiments, the air condenser 105 is an integrated ice-condensing and water-making device composed of a frost pipe network 1051 , an electric heater 1052 , and a liquid collector 106 , which is convenient for transportation and assembly.

[0028] Furthermore, in other embodiments, the radiator 102 can also be connected to multiple pipes such as a third pipe and a fourth pipe connected in parallel with the first pipe 103, and these pipes are provided with solenoid valves, expansion valves 104 and air condensers 105. A liquid collector 106 is provided at the bottom of the air condenser 105, so that the compressor 100 can work continuously and uninterruptedly to drive two or more air condensers 105 to alternately condense ice and frost, melt ice and frost to produce water.
