The ice and snow melting module is powered by solar energy to melt ice and snow to obtain fresh water. However, due to the high altitude of the plateau cold region where snow accumulates, the area is covered by clouds and fog all year round, and there are fewer sunny days, resulting in less solar energy available in winter, which cannot meet the large water supply demand.

[0003] At the same time, the warm and humid air flow of the Indian Ocean is blocked by the western plateau and high mountains, which is the main reason for the lack of rainfall in the west. The low temperature weather of the western plateau and high mountains also condenses the warm and humid air flow of the Indian Ocean, which becomes snow on the high mountains, forming a natural fresh water storage resource that can become fresh water after melting. Due to the limited amount of naturally melted fresh water, it cannot meet the water demand of a large number of people, making the west sparsely populated. Influenced by the geographical environment, the ground will form a freezing period and a warm and humid period at a certain time, causing fluctuations in fresh water supply and affecting crops.

[0020] As Figs. 1-4 shown, a fresh water acquisition device based on heat pump refrigeration technology, including heat pump system for generating heat and exhaust system for discharging heat.

[0021] The heat pump system includes a compressor 1, a four-way valve reversing valve 2, an evaporator 3, a pressure regulating valve 4 and a condenser 5 connected in sequence through a pipeline and forming a loop. Specifically, the compressor 1 refrigerant inlet communicates with the first end of the four-way valve reversing valve 2, the compressor 1 refrigerant outlet communicates with the second end of the four-way valve reversing valve 2, one end of the evaporator 3 communicates with the third end of the four-way valve reversing valve 2, the other end of the evaporator 3 communicates with one end of the pressure regulating valve 4, the other end of the pressure regulating valve 4 communicates with one end of the condenser 5, and the other end of the condenser 5 is connected to the fourth end of the four-way valve reversing valve 2.

[0022] The exhaust system 6 includes a conveying pipeline 6a, which is laid with a layer of thermal insulation material. The conveying pipeline 6a is covered on the condenser 5 at the beginning, and a plurality of exhaust fans 6b are arranged in the conveying pipeline 6a at intervals. The two adjacent exhaust fans 6b are arranged on both sides of the conveying pipeline 6a, which can avoid dead angle and balance weight, and the arrangement is reasonable. The end of the conveying pipeline 6a is fixed on the top of the mountain by the fastening net 7, which can support the exhaust system 6 and reinforce the top of the mountain to prevent stress deformation and collapse. The cold air outlet 6c is arranged at the end of the conveying pipeline 6a, and the warm air outlet 6d is arranged in the middle of the conveying pipeline 6a. In order to improve the melting effect of the warm air outlet 6d, the warm air outlet 6d is arranged at the part of the mountain where snow accumulates all year round. The exhaust one-way switching structure 8 is arranged in the conveying pipeline 6a, and the exhaust one-way switching structure 8 is arranged immediately behind the warm air outlet 6d.

[0023] The air exhaust one-way switching structure 8 includes a ring of blocking rings 8b arranged on the inner wall of the conveying pipeline 6a, and a blocking plate 8a with a diameter matching the inner diameter of the conveying pipeline 6a is arranged on the front side of the blocking rings 8b. The diameter of the warm air outlet 6d is smaller than that of the blocking plate 8a, and the side of the blocking plate 8a close to the warm air outlet 6d is rotationally connected in the conveying pipeline 6a. The blocking plate 8a is provided with a rotating motor for pressing the blocking plate 8a on the warm air outlet 6d or the blocking ring 8b. The blocking plate 8a is provided with rounded corners around the periphery for facilitating rotation and improving rotation efficiency.

[0024] The cross section of the conveying pipeline 6a and the warm air outlet 6d are both rectangular, and the side of the conveying pipeline 6a is straight plate-shaped, facilitating the pressing of the blocking plate 8a, thereby ensuring the efficiency of one-way air exhaust. In order to improve the sealing between the blocking plate 8a and the warm air outlet 6d and the blocking ring 8b, the front and rear sides of the blocking plate 8a are respectively provided with bosses 8c matching the diameters of the warm air outlet 6d and the blocking ring 8b, which can improve the one-way air exhaust effect. Further, the bosses 8c are provided with a sealing layer, which can improve the sealing effect and ensure the switching of the air exhaust duct.

[0025] In use, the heat pump system can be installed at the foot of a mountain or at a relatively low altitude on the mountain according to the geographical location, the warm air outlet 6d is arranged at a place where there is snow all year round or at least long-term snow in winter on the mountain, and the cold air outlet 6c is arranged at the top of the mountain.

[0026] The compressor 1 works in the refrigeration working condition, and the refrigerant circulates in the system, is discharged to the evaporator 3 to be cooled (to release heat), is depressurized by the pressure regulating valve 4, flows into the condenser 5 to be cooled by the surrounding air, and forms low-temperature air. The low-temperature air is forced to be discharged to the top of the mountain through the cold air outlet 6c under the action of the air exhaust system 6, and forms a low-temperature and low-pressure air flow. When the cold air discharged by the air exhaust system 6 meets the warm and humid air flow from the Indian Ocean, convection occurs, which is helpful for the exchange of heat and moisture in the atmosphere. When the water vapor in the hot and humid air meets the cold air, the water vapor condenses into small water droplets, thereby condensing and dewing the warm and humid air flow from the Indian Ocean, and freezing the water molecules in the warm and humid air flow on the mountain. The heat pump system strengthens the condensation effect, and the amount of condensation air flow obtained will increase, because there is an ultra-low-temperature air flow blown by the heat pump air exhaust system on the mountain, and the low-temperature and low-pressure air flow meets the warm and humid air flow from the Indian Ocean to produce convection, which also speeds up the warm and humid air flow. The increased flow rate will increase the condensation effect, and the amount of ice and rain obtained will also increase synchronously.

[0027] When the heat pump system is working normally, the condenser 3 will release a large amount of stable heat source, which will also increase the temperature of the surrounding air and accelerate the melting of the snow on the mountain.

[0028] When the demand for fresh water increases, the four-way reversing valve 2 works, the refrigerant flows in the opposite direction, enters the heating working condition. By rotating the motor to drive the baffle 8b to rotate to the abutment with the check ring 8a, the delivery pipeline on the back side of the second outlet 6d is closed, the second outlet 6d is opened, the heat pump system enters the warm air mode, the high temperature gas blown out from the second outlet 6d melts the surrounding snow to obtain fresh water, and the power of the heat pump system can be adjusted to adjust the temperature of the high temperature gas, and then the obtained fresh water is adjusted according to the demand, so that the amount of obtained fresh water is controllable.
