Description
Technical Field
[0001] This invention relates to the agricultural field, specifically to a dehumidification device for planting greenhouses. Background Technology
[0002] Currently, greenhouses are facilities used to provide a good growing environment for crops. Their surfaces are made of transparent materials to allow sunlight to enter the greenhouse, thus providing good light for the crops inside. Furthermore, the greenhouse is relatively enclosed compared to the outside, which can increase the temperature inside the greenhouse to meet the temperature requirements for crop growth.
[0003] However, during use, rainfall can cause the humidity inside the greenhouse to rise. In order to maintain the temperature, the air circulation between the inside and outside of the greenhouse is poor, resulting in high humidity inside the greenhouse. This can make crops susceptible to disease and affect their growth. Therefore, a dehumidification device for planting greenhouses is proposed to address the above problems. Summary of the Invention
[0004] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, the present invention proposes a dehumidification device for planting greenhouses.
[0005] The technical solution adopted by this invention to solve its technical problem is as follows: A dehumidification device for a planting greenhouse, comprising a compression chiller; a tank is installed on the side of the compression chiller, and multiple condenser pipes are installed inside the tank. The top ends of the multiple condenser pipes penetrate the tank and are fixedly connected to it. The compression chiller is connected to the condenser pipes via refrigerant pipes. An air inlet is provided on the side of the tank, and a support is fixedly connected to the top of the tank. A fan is installed on the top of the support, and a humidity sensor is installed on the support. In use, the compression chiller drives the heat exchange liquid to circulate in the refrigerant pipes and cools down the temperature of the heat exchange liquid. The fan starts, creating a negative pressure inside the tank, and then draws in air through the air inlet. The air flows through the condenser pipes, and the low temperature of the condenser pipes causes the moisture in the air to condense, thereby reducing the humidity in the air. The humidity sensor is installed inside the support, thus achieving the function of dehumidifying the greenhouse. Based on the above structural setup, the humidity inside the greenhouse can be regulated, thereby reducing the impact of excessive humidity on plant growth inside the greenhouse.
[0006] Preferably, it also includes an air inlet pipe and an air outlet pipe, both of which have openings at their bottoms. A first pipe body is fixedly connected between the end of the air inlet pipe and the air inlet, and a second pipe body is fixedly connected between the air outlet pipe and the air outlet of the fan. The first and second pipe bodies are flexible hoses. In use, the air inlet and air outlet are connected to the air inlet pipe and air outlet pipe respectively through the first and second pipe bodies. The air outlet pipe and air inlet pipe are installed inside the greenhouse and open at the bottom, thereby improving the uniformity of dehumidification inside the entire greenhouse.
[0007] Preferably, a water receiving tray is installed at the bottom of the tank, and the water receiving tray is connected to the bottom of the tank. A solenoid valve is installed at the bottom of the water receiving tray. In use, the water receiving tray is installed at the bottom of the tank, and the solenoid valve can facilitate the discharge of condensate in the water receiving tray.
[0008] Preferably, the plurality of condenser tubes are arranged in a ring in the middle of the tank. The condenser tubes are arranged in a U-shape and fins are fixed to the surface of the condenser tubes. The support is located in the middle of the plurality of condenser tubes. In use, the ring-shaped condenser tubes are installed in the tank and fins are provided on them. The fins can increase the contact area with air, thereby facilitating the cooling of air and allowing water to condense onto the fins, thus facilitating the condensation of water.
[0009] Preferably, a gas guide hood is fixedly attached to the inner wall of the tank. The gas guide hood has an annular structure, and the condenser pipe is located in the middle of the gas guide hood. An annular cavity is formed between the gas guide hood and the inner wall of the tank. The annular cavity is connected to the air inlet. Multiple air outlets are fixedly attached to the inner wall of the gas guide hood. In use, the air drawn in through the air inlet enters the annular cavity and passes through the multiple air outlets fixed to the gas guide hood. The airflow is distributed through the annular cavity into the air outlets and then enters the middle of the tank through the air outlets. By setting up the gas guide hood, the airflow can be evenly distributed, thereby facilitating condensation.
[0010] Preferably, the fins are inclined, and the multiple air outlets are arranged in a ring on the inner wall of the air guide cover. The air outlets are inclined. In use, the fins and air outlets are inclined, so that the air injected into the tank can form a vortex. Under the action of centrifugal force, the vortex can throw water droplets onto the fins on the inner wall of the tank.
[0011] Preferably, multiple demister plates are fixedly connected to the top center of the air guide hood. The condenser pipe passes through the demister plates and is fixedly connected to them. The demister plates have through holes, and the through holes of two adjacent demister plates are staggered. A metal cover is fixedly connected to the top of the through hole. The metal cover has a conical structure and multiple demister plates are fixedly connected to the top center of the air guide hood. The demister plates are connected to the condenser pipe. The airflow flows up from the through hole and impacts the demister plates to remove and reduce small water droplets in the airflow. The metal cover is installed above the through hole to facilitate the removal of water mist inside.
[0012] Preferably, a drain pipe is fixed to the side of the demister plate, a one-way valve is installed inside the drain pipe, and a notch is provided on the drain pipe above the demister plate. The drain pipe with the notch is used to drain the condensate on the demister plate. The one-way valve is installed inside the drain pipe to restrict the flow to one direction only.
[0013] The advantages of this invention are:
[0014] 1. This invention, by setting up a compression chiller, a tank, condenser pipes, a fan, and a support, allows the compression chiller to drive the heat exchange liquid to circulate in the refrigerant pipes during use, thereby cooling and reducing the temperature of the heat exchange liquid. The fan starts, creating a negative pressure inside the tank, and then draws in air through the air inlet. The air flows through the condenser pipes, and the low temperature of the condenser pipes causes the moisture in the air to condense, thus reducing the humidity in the air. A humidity sensor is installed inside the support to dehumidify the greenhouse. By setting up the above structure, the humidity inside the greenhouse can be regulated, thereby reducing the impact of excessive humidity on the growth of plants inside the greenhouse.
[0015] 2. This invention, by setting up an air inlet pipe, an air outlet pipe, a first pipe body, and a second pipe body, allows the air inlet and outlet to be connected to the air inlet pipe and air outlet pipe respectively through the first pipe body and the second pipe body during use. The air outlet pipe and the air inlet pipe are installed inside the greenhouse and through the opening at the bottom, thereby improving the uniformity of dehumidification inside the entire greenhouse.
[0016] 3. By setting up an air guide hood and air outlets, the air drawn in through the air inlet enters the annular cavity during use. Multiple air outlets are fixed to the air guide hood, and the airflow is distributed through the annular cavity into the air outlets. Then, it enters the middle of the tank through the air outlets. By setting up the air guide hood, the airflow can be evenly distributed, which facilitates condensation. Attached Figure Description
