[0031] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0032] This utility model provides an electric fluid heat pipe direct evaporative cooling air conditioner suitable for unmanned convenience stores, such as... Figure 1 As shown, the unit includes a housing 28, and air inlets 1 and air outlets 22 are respectively provided on two opposite side walls of the housing 28; the air inlet 1 is a louvered air outlet;

[0033] Inside the unit casing 28, a filter 2, a first fan 3, a surface cooler 4, and a direct evaporative cooler are arranged in sequence according to the airflow direction; an electro-hydraulic heat pipe 15 is also installed inside the unit casing 28.

[0034] When air passes through the surface cooler 4, the refrigerant inside the surface cooler 4 exchanges heat with the air.

[0035] It also includes a solar power supply unit, an electric fluid heat pipe (DYQT47 high-current solar electric heat pipe 2kw) 15, a first fan 3 and a direct evaporation cooler, all of which are connected to the solar power supply unit; filter 2 is a coarse filter;

[0036] The current-driven heat pipe (DYQT47 high-current solar electric heating pipe 2kW) can quickly transfer the heat generated by the evaporator. At the same time, it can effectively reduce temperature differences within the air conditioning system, promptly equalize the temperature, improve the stability of the entire air conditioning system, help reduce energy consumption, and make the air conditioning operation more efficient and energy-saving.

[0037] It also includes an evaporator 29, a throttling device 30, and a fan coil unit 24 located at the air outlet 22. The fan coil unit 24, evaporator 29, and throttling device 30 are all located inside the convenience store 25. The evaporator 29 and throttling device 30 are both connected to a direct evaporative cooler. (One end of the fan coil unit 24 is connected to the air outlet 22, and the other end of the fan coil unit 24 is located inside the convenience store 25). Air enters the fan coil unit 24 through the air outlet 22 and is then delivered into the convenience store through the air vent 23 to meet the temperature requirements of customers.

[0038] The direct evaporative cooler includes, from top to bottom, a second fan 20, a baffle plate 21, a water distribution device 19, a circulating refrigerant pipe 10, a packing 8, and a water storage tank 7; the packing 8 is an asbestos fiber packing, which has good heat resistance, good adsorption performance, and adopts an inverted right-angled triangular shape.

[0039] The function of the baffle plate 21 is to prevent water from the direct evaporative cooler from splashing onto the second fan 20. If water enters the fan, it may cause a decrease in the fan's performance, damage to the motor, and damage to the blades.

[0040] The water storage tank 7 is equipped with a circulating water pump 6, which is connected to the water distribution device 19 through the circulating water pipe 12.

[0041] The second fan 20 and the circulating water pump 6 are both connected to the solar power supply unit;

[0042] The refrigerant outlet 9 of the circulating refrigerant pipe 10 is connected to the throttling device 30 via a pipe, and the refrigerant inlet 11 of the circulating refrigerant pipe 10 is connected to the evaporator 29 via a pipe. One function of the circulating refrigerant pipe 10 is to transport refrigerant; it acts as a channel, transporting refrigerant from one component of the air conditioning system to another, ensuring that the refrigerant can circulate between the evaporator 29 and the throttling device 30. The changes in the refrigerant state within the circulating refrigerant pipe are accompanied by the absorption and release of heat.

[0043] The water distribution device 19 includes a water distribution pipe 19-1, and a plurality of nozzles 19-2 are provided on the water distribution pipe 19-1; the water distribution pipe 19-1 is connected to the circulating water pipe 12.

[0044] A float valve 5 is installed inside the water storage tank 7.

[0045] An overflow pipe 26 is installed on the water storage tank 7.

[0046] A water supply pipe 27 is installed on the water storage tank 7.

[0047] If the water level in the water storage tank 7 is lower than the set water level, the float valve 5 will open and water will be added to the water tank through the water supply pipe 27. After the water level returns to normal, the float valve 5 will close and the water supply pipe 27 will stop adding water. If the water level in the water storage tank 7 exceeds the overflow port height, it will automatically drain water through the overflow pipe 26.

[0048] A throttling valve 13 is installed on the circulating water pipe 12.

[0049] The solar power supply unit includes a solar panel 14, a photovoltaic inverter 17, a photovoltaic controller 16, and a battery 18 connected in sequence.

[0050] Solar panels 14 are mounted on the top outer wall of the unit casing 28;

[0051] The photovoltaic inverter 17, photovoltaic controller 16 and battery 18 are installed inside the unit casing 28;

[0052] The current-powered heat pipe 15, the second fan 20, and the circulating water pump 6 are all connected to the storage battery 18.

[0053] During the day, solar panel 14 converts solar energy into electrical energy. The variable DC voltage generated by the solar panel is converted into AC frequency by photovoltaic inverter 17. The AC power provides power to the first fan 3, the second fan 20 and the circulating water pump 6. Excess electrical energy can also be stored in battery 18.

[0054] The fan coil unit 24 has several air vents 23 on its side wall.

[0055] The entire current-current heat pipe direct evaporative cooling air conditioner is set on one side of the convenience store. After the outdoor hot air is cooled by the air conditioner, it becomes cold air and is sent into the convenience store from the side of the convenience store 25.

[0056] The working principle of this direct evaporative cooling air conditioner is as follows:

[0057] (1) Working process of the water system:

[0058] Water in the storage tank 7, driven by the circulating water pump 6, travels through the circulating water pipe 12 to the water distribution device 19. The water is then evenly sprayed onto the inverted triangular asbestos fiber packing 8. The water flows downwards under gravity, wetting the asbestos fiber packing 8, and is filtered at the air inlet 1. The treated fresh air then comes into direct contact with the filter for heat and moisture exchange. Unevaporated water in the packing 8 drips into the lower storage tank 7 under gravity, thus completing the circulating water cycle.

[0059] (2) Working process of the air system:

[0060] Fresh air from outside the convenience store enters through the adjustable louvered air inlet 1 under the action of the first fan 3. After being filtered by the filter 2, it passes through the surface cooler 4, where the refrigerant inside the surface cooler 4 exchanges heat with the air. Then it comes into contact with the asbestos fiber filler 8, undergoes isenthalpic cooling, passes through the second fan 20, then through the air outlet 22, and finally enters the convenience store 25 through the air outlet plate 23.

[0061] The electrical system operates as follows: Solar panel 14 converts solar energy into electrical energy during the day. A photovoltaic inverter 17 converts the variable DC voltage generated by the solar panel into AC power, which powers the first fan 3, the second fan 20, the circulating water pump 6, and the current-powered heat pipe 15. The current-powered heat pipe 15 quickly transfers heat generated by the evaporator. Simultaneously, it effectively reduces temperature differences within the air conditioning system, promptly equalizing the temperature and improving the overall stability of the system. Excess electrical energy can be stored in the battery 18.

[0062] (4) Working process of refrigerant system

[0063] The refrigerant flows from the refrigerant inlet 11 into the circulating refrigerant pipe 10 and is connected to the evaporator 29 via a pipe. It also flows from the refrigerant outlet 9 and is connected to the throttling device 30 via a pipe.

[0064] The operating mode of the current fluid heat pipe direct evaporative cooling air conditioner applicable to unmanned convenience stores is as follows:

[0065] When the outdoor temperature is high and during periods of high temperatures, all equipment operates normally. Specifically, the first fan 3 and the circulating water pump 6 are turned on simultaneously. Hot outdoor air enters through the air inlet 1 and first undergoes preliminary filtration through the filter 2. Subsequently, the pre-filtered fresh air passes through the surface cooler 4 and comes into contact with the moistened packing material 8 for isenthalpic cooling. Under the action of the second fan 20, it is then delivered into the convenience store through the air outlet 22. During the day, the solar panel 14 converts solar energy into electrical energy. The photovoltaic inverter 17 converts the variable DC voltage generated by the solar panel into AC power, which powers the first fan 3, the second fan 20, the circulating water pump 6, and the electro-hydraulic heat pipe 15. The electro-hydraulic heat pipe 15 can quickly transfer the heat generated by the evaporator.

[0066] When the outdoor temperature is not too high, such as at night, turn off the evaporator 29 and the throttling device 30. This helps to reduce energy consumption and make the air conditioner run more efficiently and energy-saving. Only turn on the second fan 20 in the direct evaporative cooler (while other equipment in the direct evaporative cooler is turned off). Otherwise, turn on the other equipment of the air conditioning unit normally and turn on the dry mode. This can play a certain role in cooling. This not only saves water, but also reduces the operating energy consumption of the entire system.
