Description

Technical Field

[0001] This invention relates to the field of edible fungi cultivation technology, specifically to a multi-energy complementary energy storage type humid air cultivation temperature control system and its usage method. Background Technology

[0002] Edible fungi (such as deer antler mushrooms, white oyster mushrooms, and shiitake mushrooms) thrive in temperatures between 4°C and 16°C. They require a high-humidity environment, typically above 90%. Currently, the traditional method for achieving this high humidity is using a heat pump unit combined with an ultrasonic humidifier. This method is expensive and energy-intensive. Furthermore, the frosting and defrosting process during summer cooling affects the accuracy of temperature and humidity control. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-energy complementary energy storage type humid air aquaculture temperature control system and its usage method, which solves the problems of high energy consumption and frosting and defrosting operations during summer cooling when using heat pump units + ultrasonic humidifiers to create a high humidity environment for edible fungi.

[0004] The technical solution adopted by this invention to solve its technical problem is: a multi-energy complementary energy storage type humidified air aquaculture temperature control system, including an aquaculture chamber, a packing heat exchanger, a water storage tank, a heat pump unit, and a solar collector. The packing heat exchanger is located inside the aquaculture chamber. A water tank is located below the packing heat exchanger, and a return air vent is located between the water tank and the bottom of the packing heat exchanger. A fan and an air outlet are located above the packing heat exchanger. When the fan is working, the air in the aquaculture chamber enters the packing heat exchanger through the return air vent for humidification, and then exits through the air outlet. The airflow returns to the breeding room through the vent; the water storage tank is buried underground outside the breeding room. The water storage tank is connected to the water tank through a recovery pipe and to the spray assembly on the top of the packing heat exchanger through a water supply pipe. In summer, the water storage tank is also connected to the heat pump unit through a circulation pipe, and the heat energy in the water storage tank is transferred to the heat pump unit. At this time, the water storage tank achieves cold storage. In winter, the water storage tank is also connected to the solar collector through a circulation pipe, and the solar collector exchanges heat with the water storage tank. At this time, the water storage tank achieves heat storage.

[0005] Furthermore, the packing heat exchanger is located on the inner wall of the breeding chamber.

[0006] Furthermore, the packed heat exchanger includes a shell and baffles. The baffles are located inside the shell and are arranged in multiple groups from top to bottom. Each group includes two baffles with opposite inclination directions, and the arrangement of the baffles forms an S-shaped airflow path inside the shell. The spray assembly is located between the two uppermost groups of baffles.

[0007] Furthermore, the lower end of the baffle is fixedly connected to the inner wall of the outer casing, and the upper end of the baffle faces the opposite side of the inner wall of the outer casing and has a gap with the opposite side of the inner wall of the outer casing.

[0008] Furthermore, the baffle plate has uniformly arranged through holes.

[0009] Furthermore, the gaps between the upper and lower baffles and the inner wall of the outer casing are smaller than the gap between the middle baffle and the inner wall of the outer casing.

[0010] Furthermore, the angle between the baffle and the horizontal direction is the same, and the lengths of the upper and lower baffles are greater than the length of the baffle located in the middle.

[0011] Furthermore, the baffles are of the same length, and the tilt angles of the upper and lower baffles relative to the horizontal plane are smaller than the tilt angle of the middle baffle relative to the horizontal plane.

[0012] Furthermore, a static pressure box is provided between the fan and the packing heat exchanger, and the cross-sectional area of ​​the static pressure box is larger than that of the packing heat exchanger.

[0013] This invention also provides a method for using a multi-energy complementary energy storage type humid air aquaculture temperature control system, comprising the following steps:

[0014] S1. In summer, the water storage tank is connected to the heat pump unit, and the fan is started to draw the air in the breeding room into the packing heat exchanger through the return air vent. At the same time, cold water with a temperature of 5℃-10℃ in the water storage tank is sprayed onto the upper part of the packing heat exchanger through the spray assembly via the water supply pipe. After the air and cold water exchange heat and moisture, they become humid air with a temperature between 10℃-15℃ and a humidity of 95%. The humid air is discharged into the breeding room through the air outlet.

[0015] S2. In winter, connect the water storage tank to the solar collector, start the fan, and draw the air from the breeding room into the packing heat exchanger through the return air vent. At the same time, hot water at a temperature of 25℃-35℃ from the water storage tank is sprayed onto the upper part of the packing heat exchanger through the spray assembly via the water supply pipe. After heat and moisture exchange between the air and the hot water, the air becomes humid air with a temperature between 10℃-15℃ and a humidity of 95%. The humid air is discharged into the breeding room through the air outlet.

[0016] The beneficial effects of this invention are as follows: This invention uses a packed heat exchanger to treat the air with heat and humidity, ensuring that the relative humidity of the humid air is above 95%, meeting the growth requirements of edible fungi. By incorporating an energy storage tank, the energy stored in the heat pump unit can balance the load fluctuations of the cold storage during summer, reducing infrastructure costs and achieving the goal of saving initial investment. This invention also avoids the problem of frost formation and the need for defrosting. Attached Figure Description

[0023] like Figures 1 to 5 As shown, the present invention includes a breeding room 1, a packing heat exchanger 2, a water storage tank 5, a heat pump unit 6, a fan 7, and a solar collector 9. The present invention will be described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 5 As shown, a multi-energy complementary energy storage type humidified air aquaculture temperature control system includes an aquaculture chamber 1, a packed heat exchanger 2, a water storage tank 5, a heat pump unit 6, and a solar collector 9. The aquaculture chamber 1 is the aquaculture site for edible fungi. The packed heat exchanger 2 is located inside the aquaculture chamber 1. Below the packed heat exchanger 2 is a water tank 3, and between the water tank 3 and the bottom of the packed heat exchanger 2 is a return air inlet 4. Water in the packed heat exchanger 2 falls into the water tank 3 under gravity. Above the packed heat exchanger 2 are a fan 7 and an air outlet 8. One side of the fan 7 is connected to the top of the packed heat exchanger 2, and the air outlet 8 is located on the other side of the fan 7. After the fan 7 is started, the fan 7 draws air from the packed heat exchanger 2 and discharges it through the air outlet 8. At this time, a negative pressure is formed inside the packed heat exchanger 2, and the air in the aquaculture chamber 1 enters the packed heat exchanger 2 through the return air inlet 4, is humidified inside the packed heat exchanger 2, and finally flows back into the aquaculture chamber 1 through the air outlet 8. The packing heat exchanger 2 is installed on the inner wall of the breeding chamber 1, i.e., on the side wall, to save space.

[0025] like Figure 1 , Figure 2As shown, the water storage tank 5 is buried underground outside the breeding room 1. The water storage tank 5 is connected to the water tank 3 through a recycling pipe 51, so that the water in the water tank 3 flows back to the water storage tank 5 through the recycling pipe 51. Figure 3 As shown, the water storage tank 5 is also connected to the spray assembly 55 on the upper part of the packed heat exchanger 2 via a water supply pipe 52. The water supply pipe 52 is equipped with a water pump 53. After the water pump 53 is started, water from the water storage tank 5 enters the spray assembly 55 through the water supply pipe 52 and is sprayed onto the upper part of the packed heat exchanger 2. In summer, as... Figure 1 As shown, the water storage tank 5 is connected to the heat pump unit 6 via a circulation pipe 54. Heat energy in the water storage tank 5 is transferred to the heat pump unit 6. At this time, the water in the water storage tank 5 is cold water at 5℃-10℃, thus achieving cold storage. In winter, as... Figure 2 As shown, the water storage tank 5 is connected to the solar collector 9 through the circulation pipe 54. The solar collector 9 exchanges heat with the water storage tank 5 to heat the water in the water storage tank 5, at which time the water storage tank 5 achieves heat storage.

[0026] like Figure 3 As shown, the packed heat exchanger 2 includes a shell 21 and baffles 22. Multiple sets of baffles 22 are located inside the shell 21, arranged sequentially from top to bottom. Each set includes two baffles 22 with opposite inclination directions, arranged vertically or horizontally. The lower end of each baffle 22 is fixedly connected to the inner wall of one of the shells 21, and the upper end of each baffle 22 faces the opposite side of the inner wall of the shell 21, with a gap between them. This arrangement of the baffles 22 creates an S-shaped airflow path inside the shell 21, allowing air to flow along this path. Specifically, the lower end of the left baffle 22 is fixedly connected to the left inner wall of the shell 21, and the upper end of the left baffle 22 faces the right inner wall of the shell 21; the lower end of the right baffle 22 is fixedly connected to the right inner wall of the shell 21, and the upper end of the right baffle 22 faces the left inner wall of the shell 21. The spray assembly 55 is located between the two uppermost sets of baffles 22. On one hand, it prevents the water or water mist sprayed by the spray assembly 55 from being directly sucked away by the fan 7. On the other hand, the water or water mist is sprayed from the upper part of the packed heat exchanger 2, allowing it to fall under gravity and cover the entire packed heat exchanger 2, ensuring effective humidification of the air entering the packed heat exchanger 2. Figure 4 As shown, the baffle plate 22 has uniformly arranged through holes 23. The through holes 23 are arranged so that water flows through them and falls, and air also flows through them and rises. When air and water meet in the through holes 23, the impact enhances the humidification effect on the air. The through holes 23 are arranged so that some air flows along an S-shaped airflow path, while other air flows upwards after passing through the through holes 23.

[0027] As another structural form of the packed heat exchanger 2 of the present invention, such as Figure 5 As shown, the gaps L1 between the upper and lower baffles 22 and the inner wall of the outer shell 21 are smaller than the gap L2 between the middle baffle 22 and the inner wall of the outer shell 21. Thus, the spaces between the upper and lower baffles 22 and the inner wall of the outer shell 21 are smaller than the spaces between the middle baffle 22 and the inner wall of the outer shell 21, allowing air to enter and exit the packing heat exchanger 2 quickly, while flowing at a relatively low speed inside the packing heat exchanger 2 to ensure adequate humidification of the air.

[0028] To achieve different gap sizes between the baffles 22 at different locations within the packed heat exchanger 2 and the inner wall of the outer shell 21, one approach is to ensure that all baffles 22 have the same angle with the horizontal direction, and that the lengths of the upper and lower baffles 22 are greater than the length of the middle baffle. This brings the upper ends of the upper and lower baffles 22 closer to the corresponding inner walls of the outer shell 21. Another approach is to ensure that all baffles 22 have the same length, and that the inclination angles of the upper and lower baffles 22 relative to the horizontal plane are smaller than the inclination angles of the middle baffle.

[0029] The air is humidified inside the packed heat exchanger 2, becoming highly humid air that carries a certain amount of water droplets.

[0030] To prevent water droplets from entering the breeding room 1 with the high humidity air, such as Figure 1 As shown, a plenum chamber 10 is located between the fan 7 and the packed heat exchanger 2. The cross-sectional area of ​​the plenum chamber 10 is larger than that of the packed heat exchanger 2. Thus, when high-humidity air enters the plenum chamber 10, the increased flow space reduces the air velocity, causing water droplets in the high-humidity air to fall under gravity, achieving separation between the high-humidity air and the water droplets. The height of the plenum chamber 10 can be set to 400-800 mm.

[0031] The present invention discloses a method for using a multi-energy complementary energy storage type humid air aquaculture temperature control system, comprising the following steps:

[0032] S1. In summer, connect the water storage tank 5 to the heat pump unit 6, start the fan 7, and draw the air in the breeding room 1 into the packing heat exchanger 2 through the return air vent 4. At the same time, through the water supply pipe 52, cold water with a temperature of 5℃-10℃ in the water storage tank 5 is sprayed onto the upper part of the packing heat exchanger 2 through the spray assembly 55. After the air and cold water exchange heat and moisture, they become humid air with a temperature between 10℃-15℃ and a humidity of 95%. The humid air is discharged into the breeding room 1 through the air outlet 8.

[0033] S2. In winter, connect the water storage tank 5 to the solar collector 9, start the fan 7, and draw the air in the breeding room 0 into the packing heat exchanger 2 through the return air vent 4. At the same time, hot water at a temperature of 25℃-35℃ in the water storage tank 5 is sprayed onto the upper part of the packing heat exchanger 2 through the spray assembly 55 via the water supply pipe 52. After the air and hot water exchange heat and moisture, it becomes humid air with a temperature between 10℃-15℃ and a humidity of 95%. The humid air is discharged into the breeding room 1 through the air outlet 8.

[0034] This invention employs a packed heat exchanger 2 to treat the air with heat and humidity, maintaining a relative humidity of over 95% to meet the growth requirements of edible fungi. The baffles 22 within the packed heat exchanger 2 extend the air's movement path, ensuring effective humidification. The through-holes 23 on the baffles 22 allow air and water to impact within them, further enhancing humidification. The gaps between the baffles 22 on the upper and lower sides of the packed heat exchanger 2 and the inner wall of the outer shell 21 are smaller than the gap between the middle baffle 22 and the inner wall of the outer shell 21, allowing air to enter and exit the packed heat exchanger 2 quickly while maintaining a relatively low flow rate within the packing heat exchanger 2, thus ensuring effective humidification. The inclusion of an energy storage (heat and cold storage) water tank 5 allows for the balancing of cold storage load fluctuations during summer through the energy storage of the heat pump unit 6, reducing infrastructure costs and saving initial investment. Solar energy and heat pumps complement each other, with energy stored in the water tank. This invention can fully utilize energy-saving methods such as peak-valley electricity, energy recovery, and cross-seasonal energy storage to achieve comprehensive energy utilization. It also avoids the problem of frosting and the need for defrosting.
