The working principle of the invention is as follows: the humidity in the greenhouse is monitored in real time through a humidity sensing probe on the indoor dehumidification host machine, when the humidity exceeds an early warning value, a cooling liquid circulating pump is controlled to operate, so that cooling liquid in a cooling liquid container is input into the gas heat exchange tube 1 to form a circulating loop, an indoor exhaust fan is controlled to operate immediately, indoor air is input into the gas heat exchange tube 1, the indoor air is liquefied when meeting cold after entering the gas heat exchange tube 1, a gas dehumidification effect is achieved, and adverse effects on animals and plants caused by overhigh humidity in the greenhouse are avoided;
after the indoor air is guided by the exhaust fan, the indoor air is conveyed between the inner wall of the gas heat exchange tube 1 and the outer wall of the thin-wall metal tube 4, and the air beam is concentrated and guided to be attached to the outer wall of the thin-wall metal tube 4 by the gathering action of the basin-shaped airflow guide cover 7 to form a wrapping type forward propulsion, so that the indoor air in the gas heat exchange tube 1 with a larger tube diameter can be in close contact with the outer wall of the thin-wall metal tube 4, further the air liquefaction and dehumidification effects are ensured, in addition, the air beam part guided by the basin-shaped airflow guide cover 7 and the inner side of the basin-shaped backflow guide cover 8 form impact and rebound, further the horizontal air beam is matched to form an air beam flow direction which is overturned outwards along the periphery of the basin-shaped backflow guide cover 8, in the process, the staying time of the air beam between the basin-shaped airflow guide cover 7 and the basin-shaped backflow guide cover 8 can be effectively prolonged, and simultaneously, the device can also play a role in homogenizing and mixing the air flow, so that the air flow of different layers can be well contacted and liquefied, the dehumidification effect on the indoor air is further improved, the surrounding type 'detention' liquefaction dehumidification effect on the indoor air is realized, and the heat conversion rate of the gas heat exchange tube 1 is also improved;
because the vibration spring 11 is adopted to realize the 'hanging' type installation mode for the thin-wall metal pipe 4, when a cooling liquid circulating pump inputs cooling liquid into the thin-wall metal pipe 4 through the condensation communicating pipe 3 and forms a circulating loop, the circulation of the cooling liquid in the thin-wall metal pipe 4 can drive the plurality of rotary scoops 15 at different positions to rotate, and further causes interference to the flowing state of the cooling liquid, so that the thin-wall metal pipe 4 vibrates under the elastic connection action of the vibration spring 11, in addition, when the plurality of rotary scoops 15 at adjacent positions rotate, the flowing of the cooling liquid at the periphery of the corresponding position can also generate mutual influence, thereby improving the vibration frequency of the thin-wall metal pipe 4, further leading the air to be dripped in time when meeting water drops formed by cold liquefaction on the surface of the thin-wall metal pipe 4, and ensuring that the indoor air can keep close contact with the outer wall of the thin-wall metal pipe 4, the heat conversion efficiency of the gas heat exchange pipe 1 is further improved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
