Description

Technical Field

[0001] This utility model relates to a rotary total heat exchanger that can adjust the temperature and humidity in a greenhouse. Background Technology

[0002] Venlo-style greenhouses are a common type of agricultural planting facility. However, due to direct sunlight, the temperature inside these greenhouses rises very high, often requiring the opening of skylights for cooling. This presents two disadvantages for high-standard greenhouses: 1. Pests can enter the greenhouse through the skylights; 2. Carbon dioxide (CO2) added to high-standard greenhouses to increase crop yields can escape.

[0003] Therefore, existing technologies employ heat pump air conditioning to cool the interior of greenhouses. However, this method is costly, and humidity control requires additional equipment.

[0004] A rotary total heat exchanger (total heat rotor) consists of a rotor core, seals, a housing, and a power mechanism. Using a honeycomb rotor core as the heat transfer medium, it absorbs energy from high-temperature gas and releases it into low-temperature gas, achieving energy conversion between gases. During summer operation, as indoor exhaust air passes through the heat recovery rotor, the rotor core absorbs the cooling energy from the room air, lowering its temperature and humidity. When the rotor core rotates to the intake side and comes into contact with fresh outdoor air, it releases cooling energy to the warmer fresh air and absorbs moisture, thus cooling and dehumidifying the fresh air. In winter, the opposite occurs, increasing the temperature and humidity of the fresh air. By recovering the heat and cold from the exhaust air, the system's cooling and heating capacity is reduced, achieving energy savings. Utility Model Content

[0014] The present invention will now be described in detail with reference to specific embodiments.

[0015] See Figure 1 and Figure 2 The diagram shown is a structural schematic of an embodiment of this utility model. In this embodiment, the agricultural total heat treatment device is used for cooling a Venlo greenhouse. The device includes an outer shell, an insect-proof grille, a total heat treatment rotor, a PID air valve, and other structures. Detailed description follows.

[0016] The outer shell 1 comprises an integral upper section, a middle section, and a lower section. A first air inlet 11 is located on one side of the upper section, and a second air inlet 12 is located on the other side. The first air inlet 11 is connected to the Venlo greenhouse 2 via a pipe. High-temperature, high-humidity air from the Venlo greenhouse 2 enters the upper section of the outer shell 1 through the first air inlet 11. A first fan 3 is located behind the first air inlet 11. The first fan 3 accelerates the entry of the high-temperature, high-humidity air from the Venlo greenhouse 2 into the upper section. An insect-proof grille 8 is installed at the second air inlet 12 to prevent pests from entering during air intake. A PID valve 4 is installed at the second air inlet 12. The PID valve 4 controls the opening and closing of the second air inlet 12. A first air outlet 13 is located on the side of the middle section of the outer shell 1 corresponding to the first air inlet 11. The first air outlet 13 is connected to the Venlo greenhouse 2 via a pipe. Cooled and dehumidified air is then returned to the Venlo greenhouse 2 through this outlet. A third air inlet 14 is formed on one side of the lower section corresponding to the first air inlet 11, and the insect-proof grille 8 is installed at the third air inlet 14. A second air outlet 15 is formed on the other side of the lower section, and the insect-proof grille 8 is installed at the second air outlet 15. A second fan 5 is installed inside the second air outlet 15 to accelerate airflow. A region for heat exchange with the total heat exchange wheel 6 is formed between the third air inlet 14 and the second air outlet 15 of the lower section.

[0017] The total heat transfer rotor 6 is fixed inside the outer shell 1 and located in the middle and lower sections. The air inlet of the total heat transfer rotor 6 is connected to the upper section, ensuring that all high-temperature, high-humidity gas entering the greenhouse is processed by the rotor 6. The air outlet of the total heat transfer rotor 6 is connected to the first air outlet 13, and the processed gas enters the greenhouse from the first air outlet 13. The drive mechanism 7 of the total heat transfer rotor is located inside the outer shell, connected to the rotor and driving its rotation. Driven by the first fan 3, the high-temperature, high-humidity gas in the greenhouse passes through the pipes and interacts with the heat transfer rotor 6, cooling the gas while retaining the carbon dioxide concentration. This allows the gas to flow back into the greenhouse, preventing the release of carbon dioxide (which is added to greenhouse gases to enhance plant growth), thus achieving better plant growth and preventing insects from entering the greenhouse.

[0018] When there is gas convection between the inside and outside of the greenhouse, the PID air valve 4 is open, the total heat transfer wheel is not working, and the gas inside the greenhouse convects through the first air inlet 11 and the second air inlet 12, and the third air inlet 14 and the second air outlet 15. When the greenhouse is in internal circulation mode, the PID air valve 4 is closed, the total heat transfer wheel rotates, and the gas inside the greenhouse is processed by the total heat transfer wheel to complete the heat exchange between the inside and outside.

[0019] This structure adopts an integrated and compact design (three-layer assembly structure), which reduces the equipment footprint and maximizes the effective planting area for agriculture.

[0020] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
