Abstract
Description
Technical Field
[0001] The utility model relates to air processing equipment, in particular to a vertical air processing unit used in a plant isolation negative pressure cultivation room. Background Art
[0002] With current technology, air handling equipment used in isolated, negative-pressure plant cultivation rooms, such as glass greenhouses, is limited in use, and air conditioning manufacturers lack the necessary equipment for these specialized environments. Current technology generally utilizes standard air conditioning terminal equipment, such as ceiling-mounted air conditioning units, cabinet-type air conditioning units, and fan coil units. However, the typical floor area of a plant isolation, negative-pressure cultivation room is approximately 15-25 square meters. The ceilings are equipped with external and internal sunshades, fill lights, lighting, UV lamps, and structural beams. Standard cabinet-type air conditioners and fan coil units cannot meet the comprehensive air treatment requirements of isolated, negative-pressure plant cultivation rooms. Furthermore, if ceiling-mounted or cabinet-type air handling units are used, their large size and height will inevitably result in either top-shading or high-level blocking of sunlight, severely limiting light availability for plant growth. Summary of the Invention
[0003] In order to solve the problems of the prior art, the utility model provides a vertical air handling unit for a plant isolation negative pressure cultivation room, which can ensure the lighting of plants in the plant isolation negative pressure cultivation room, integrate cooling, heating, humidification, dehumidification and fresh air functions into one, reduce the equipment footprint, and is simple and convenient to install. The height of the equipment is reduced to reduce side light obstruction, thereby ensuring the operation safety of the plant isolation negative pressure cultivation room.
[0004] The technical solutions adopted in this utility model are as follows:
[0005] A vertical air handling unit for a plant isolation negative pressure cultivation room comprises an aluminum alloy frame, which is divided into an upper space and a lower space. The inner wall of the lower space is provided with an insulation shell, and the lower space is provided with a surface cooler and a fresh air system. The surface cooler divides the lower space into a front area and a rear area. A ventilation panel is provided on the aluminum alloy frame in front of the front area, and the rear area is connected to the upper space. A circulating fan and a humidifier are provided in the upper space. The air outlet of the circulating fan is connected to a soundproofing treatment box arranged at the top of the upper space, and the top of the soundproofing treatment box is connected to an adjustable shutter air outlet arranged at the top of the aluminum alloy frame.
[0006] Preferably, the surface cooler includes a cooling surface cooler and a heating surface cooler, the cooling surface cooler is connected to the condensing water pipe, the heating surface cooler is provided with a water inlet pipe and a water outlet pipe, and a fresh air regulating valve is provided in the fresh air system below the surface cooler.

[0012] The beneficial effects brought about by the technical solution provided by the utility model are:
[0013] (1) The whole machine adopts a vertical structure, which reduces the height of the indoor air handling unit equipment, thereby reducing the partial sunlight blocking the cultivated plants.
[0014] (2) An independent device that integrates cooling, heating (auxiliary electric heating), humidification, dehumidification, and fresh air treatment, which reduces the equipment footprint and simplifies equipment installation.
[0015] (3) There is no installation trouble caused by equipment separation, and the humidifier can be installed independently.
[0016] (4) The combination of multiple circulating fans increases the stability of the equipment. In the event that one circulating fan fails, the other two fans can continue to work, ensuring the operational safety of the negative pressure isolation room.
[0017] (5) An electric regulating valve for fresh air is installed at the bottom, so that the fresh air duct can be laid below the ground, reducing the defect of the fresh air duct being laid on the ground and blocking the sunlight; it also solves the problem of fresh air input being processed by the air handling unit before entering the room, effectively solving the large fluctuation of the indoor greenhouse caused by the fresh air entering the room and the impact on indoor environmental factors.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Example 1
[0022] As attached Figure 1 As shown, a vertical air handling unit for a plant isolation negative pressure cultivation room in this embodiment includes an aluminum alloy frame 1, which is divided into an upper space and a lower space. The inner wall of the lower space is provided with an insulation shell 13, and the lower space is provided with a surface cooler and a fresh air system 2. The surface cooler divides the lower space into a front area and a rear area. A ventilation panel 3 is provided on the aluminum alloy frame 1 in front of the front area, and the rear area is connected to the upper space. A circulating fan 4 and a humidifier 5 are provided in the upper space, and the air outlet of the circulating fan 4 is connected to a soundproofing treatment box 6 arranged at the top of the upper space, and the top of the soundproofing treatment box 6 is connected to an adjustable shutter air outlet 7 arranged at the top of the aluminum alloy frame.
[0023] In this embodiment, the surface cooler includes a cooling surface cooler 8 and a heating surface cooler 9. The cooling surface cooler 8 is connected to the condensing water pipe 10, and the heating surface cooler 9 is provided with an inlet pipe 11 and an outlet pipe 12. A fresh air regulating valve 21 is provided in the fresh air system 2 below the surface cooler.
[0024] The surface cooler of this embodiment is installed at a 50-degree angle to facilitate sufficient cooling and heating of the air.
[0025] A filter screen with a filter element is provided in the ventilation panel 3 .
[0026] This embodiment is a floor-standing installation at a height of 1.2 meters (without blocking light). Air intake is located on the front facade, with a metal frame panel installed on the inlet side. A manually removable ventilation panel with a door-type suction (no screw fastening) is used. Inside the ventilation panel, a removable and cleanable filter and a multifunctional filter element (activated carbon, PM2.5 filter, or other existing sterilization device) are installed. The frame is constructed of a dedicated aluminum alloy cold-break bridge profile and 30mm polyurethane color-coated steel sheeting. The top outlet features an adjustable air vent.
[0027] The surface coolers are available in cooling, heating, or combined dehumidification configurations. Both the cooling and heating surface coolers are installed at a 50-degree angle, with a fresh air control valve installed below. A compact ultrasonic humidifier is mounted above the surface coolers. Recirculating air from the room is filtered through activated carbon filters and mixed with a fixed amount of fresh air regulated by the fresh air valve. After humidification by the cooling and heating surface coolers, it is pressurized by a circulation fan and delivered to a silencing treatment chamber. The treated mixed air is then released into the room through adjustable louvers at the top. The circulation fans utilize three external rotors with three speed settings, reducing installation width and height compared to a single fan, effectively reducing the overall equipment footprint.
[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
