[0037] Combine Figure 1-6 As shown, the embodiment of the present disclosure provides a water source heat pump air heat exchange circulation device, including: a water source heat pump 100, used for exchanging heat with the air in the greenhouse; an air inlet 101, arranged at the upper part of the water source heat pump 100; an air outlet 102, arranged at the lower part of the water source heat pump 100; a positive pressure air duct 200, connected to the air outlet 102, and the positive pressure air duct 200 is a tubular structure with a hollow interior, and an air outlet 201 is arranged on the side wall of the positive pressure air duct 200; a seedling bed 300, arranged at the upper part of the positive pressure air duct 200.

[0038] By using the water source heat pump 100 air heat exchange circulation device provided in the embodiment of the present disclosure, the water source heat pump 100 can exchange heat and heat the air in the greenhouse. The seedbed 300 needs to maintain the temperature in the greenhouse when cultivating seedlings. The water source heat pump 100 can exchange heat and heat the air in the greenhouse. The air in the upper part of the greenhouse can be drawn into the water source heat pump 100 through the air inlet 101 for heat exchange, and then the heated air is discharged from the air outlet 102. The discharged air enters the positive pressure air duct 200. The air can be concentrated through the positive pressure air duct 200, and then the hot air is discharged from the air outlet 201 on the positive pressure air duct 200 to heat the seedbed 300. The air outlet 201 on the positive pressure air duct 200 can achieve comprehensive heating of the bottom of the seedbed 300.

[0039] Optionally, an air guide plate 202 is provided between the seedbed 300 and the positive pressure air duct 200 , the air outlet 201 on the positive pressure air duct 200 is provided at the upper portion of the positive pressure air duct 200 , and the air guide plate 202 cover is provided at the upper portion of the air outlet 201 .

[0040] In this way, the air guide plate 202 is set between the seedling bed 300 and the positive pressure air duct 200, so that the hot air discharged from the air outlet 201 on the positive pressure air duct 200 can be blocked and diverted, and the hot air in the air outlet 201 can be prevented from blowing directly to the bottom of the seedling bed 300. Through the diversion of the guide plate, the hot air can flow stably into the bottom of the seedling bed 300, and the diversion and diversion of the air guide plate 202 can achieve heating of a large area of ​​the seedling bed 300.

[0041] Optionally, the cross section of the wind deflector 202 is an arc-shaped structure, and the arc-shaped surface of the wind deflector 202 is arranged toward the seedbed 300 .

[0042] In this way, the arc-shaped air guide plate 202 can guide the condensed water or seeping water on the upper part of the bed to the side of the positive pressure air duct 200. The air guide plate 202 can prevent water from dripping into the positive pressure air duct 200, thereby preventing water accumulation in the positive pressure air duct 200 and causing the growth of bacteria and fungi.

[0043] Optionally, the positive pressure air duct 200 is arranged in parallel in multiple numbers, and the positive pressure air ducts 200 are arranged at intervals, and the air guide plate 202 is arranged on the upper part of the positive pressure air duct 200.

[0044] In this way, a plurality of positive pressure air ducts 200 arranged in parallel can increase the heating area of ​​the seedling bed 300, and uniform heating of various parts of the seedling bed 300 can be achieved through the positive pressure air ducts 200.

[0045] Optionally, air outlets 203 are respectively provided on both sides of the positive pressure air duct 200 , and the diameter of the air outlet 203 is smaller than the diameter of the air outlet 201 .

[0046] In this way, the positive pressure air duct 200 is also provided with exhaust ports 203 on both sides. The exhaust ports 203 can divert the exhaust of the air outlet 102, which can increase the exhaust volume of the positive pressure air duct 200, reduce the exhaust speed of the air outlet 102, and ensure that the air in the positive pressure air duct 200 flows stably to the bottom of the seedling bed 300.

[0047] Optionally, an air dividing plate 204 is horizontally arranged in the positive pressure air duct 200, and the air dividing plate 204 divides the positive pressure air duct 200 into an upper cavity 205 and a lower cavity 206. A return air outlet 207 is provided at one end of the air dividing plate 204 away from the air outlet 102, and the upper cavity 205 and the lower cavity 206 are connected through the return air outlet 207.

[0048] In this way, the air dividing plate 204 can divide the cavity inside the positive pressure air duct 200 into an upper cavity 205 and a lower cavity 206. The air in the air outlet 102 can enter the upper cavity and the lower cavity respectively. The exhaust port 203 and the air outlet 201 are both arranged on the upper cavity. The air dividing plate 204 is provided with a return air port 207 at one end away from the air outlet 102. The return air port 207 can connect the upper cavity 205 and the lower cavity 206. The air in the lower cavity 206 can enter the upper cavity from the return air port 207 or one end of the air outlet 102 respectively. In this way, the air can be evenly mixed in the positive pressure air duct 200, so that the temperature of the discharged air in the positive pressure air duct 200 can be balanced.

[0049] Optionally, a circulation fan 208 is provided at one end of the lower cavity 206 close to the air outlet 102 .

[0050] In this way, the circulation fan 208 near the air outlet 102 of the lower cavity 206 can supply air into the lower cavity 206, so that the air pressure in the lower cavity 206 can be higher than that in the upper cavity 205. The air in the lower cavity 206 can then enter the upper cavity 205 through the return air outlet 207. In this way, the air can enter from both ends of the upper cavity, so that the air in the upper cavity can be mixed by convection, and the air temperature in the upper cavity can be evenly mixed.

[0051] Optionally, a plurality of circulation air holes 209 are arranged in parallel on the air distribution plate 204 .

[0052] In this way, the circulating air holes 209 on the air distribution plate 204 can allow the air in the lower cavity 206 to enter the upper cavity 205 from the middle of the middle air distribution plate 204, so that the air in the upper cavity 205 can be better mixed.

[0053] Optionally, the plurality of circulating air holes 209 increase in size from one end of the air outlet 102 toward one end of the return air outlet 207 .

[0054] In this way, the circulating air holes 209 gradually increase in size toward one end of the return air outlet 207, so that the air in the lower cavity can enter the upper cavity in a gradually increased manner, so that the air in the lower cavity can be better mixed in the upper cavity. The circulating air holes 209 with different apertures can make the air pressure entering the upper cavity different, thereby increasing the circulation and mixing of air in the upper cavity.

[0055] Optionally, the seedbed 300 is provided with parallel support rods 301 , and the air inlet 101 is provided on the upper portion of the support rods 301 .

[0056] In this way, the support rods 301 on the seedbed 300 can play a role in supporting the nursery. The air inlet 101 is set on the support rods 301, so that the air passing through the nursery enters the water source heat pump 100 through the air inlet 101 for heat exchange.
