Abstract
Description
Technical Field
[0001] The utility model relates to the field of industrial equipment, in particular to a low-temperature dehumidification air-conditioning box. Background Art
[0002] Rotary dehumidifiers are widely used in many fields due to their large dehumidification capacity, good dehumidification effect, wide application area and fully automatic control.
[0003] like Figure 1 As shown in the figure, a rotary dehumidifier utilizes a rotating wheel made of solid desiccant for dehumidification. The wheel is covered with honeycomb-shaped channels. As air flows through these channels, it exchanges heat and moisture with the channel walls. The channel walls, which contain solid desiccant, are cooled by the air, and their corresponding water vapor partial pressure becomes lower than that of the treated air. Water vapor is then adsorbed into the desiccant. Simultaneously, the sensible heat of the wheel itself and the heat of adsorption increase the air temperature. As the wheel rotates, the moisture absorption capacity of these channels gradually reaches saturation. When these desiccant channels rotate to the regeneration zone, hot air flows through these honeycomb channels. The channel walls containing the solid desiccant are heated, and their corresponding water vapor partial pressure becomes higher than that of the regenerated air, driving moisture out of the desiccant. As the wheel rotates and desorption proceeds, the honeycomb-shaped desiccant channels regain their moisture absorption capacity and are rotated back to the dehumidification zone. This cycle repeats, allowing the dehumidification process to continue.
[0004] According to the principle of a rotary dehumidifier, a hot air duct is required. This duct uses steam or hot water coils to heat the air flowing through it, which then absorbs the moisture from the solid desiccant in the rotor. A fan then removes the moisture-laden hot air from the unit. During this process, hot water or steam is required to heat the hot air leaving the unit, but this energy does not contribute to air conditioning. The exhaust fan at the end of the hot air duct also has no effect on air conditioning. Because the hot and cold air ducts are installed side by side, they take up a lot of space and the unit is heavy, making transportation and installation inconvenient. Utility Model Content
[0005] The purpose of the utility model is to overcome the above-mentioned defects and provide a space-saving, energy-saving, low-temperature dehumidification air-conditioning box.
[0006] In order to achieve the above object, the utility model is achieved as follows:
[0007] A low-temperature dehumidification air-conditioning box includes an air duct, a dehumidification module, a heating module and an air supply module. The dehumidification module, heating module and air supply module are arranged in the air duct in sequence. The air flow entering the air duct passes through the dehumidification module and the heating module in sequence and is then sent out through the air outlet of the air duct by the air supply module.
[0008] The above-mentioned low-temperature dehumidification air-conditioning box and the dehumidification module refer to ice storage equipment.
[0009] The above-mentioned low-temperature dehumidification air-conditioning box proposed by the present invention utilizes an ice storage device to provide low-temperature chilled water (close to) for the dehumidification section of the dehumidification air-conditioning box, so that the air flowing through the air-conditioning box is extremely cooled. A large amount of water vapor in the air solidifies into liquid water when it is cold, and separates from the air to achieve the purpose of deep dehumidification.
[0010] The advantage of this utility model is that the existing air-conditioning box is affected by the temperature of the chilled water (generally the chilled water temperature is 7~) and cannot meet the requirements of deep dehumidification. The utility model utilizes the characteristics of the ice storage device and the principle of dehumidification of the air-conditioning box, combines the two in an orderly manner, replaces the rotary dehumidifier, and solves the problem of excess energy consumption of the rotary machine unit.
[0011] Furthermore, the above-mentioned low-temperature dehumidification air-conditioning box also includes a filtering module and a pre-cooling module. The pre-cooling module includes a first pre-cooling module and a second pre-cooling module. The filtering module includes a primary filtering module and a medium filtering module. The first pre-cooling module, the second pre-cooling module, the primary filtering module and the medium filtering module are arranged in the air duct at intervals.
[0012] In the above process, the purpose of filtration is to remove dust impurities in the air, and the purpose of pre-cooling is to cool the air and reduce the air temperature.
[0013] Furthermore, the low-temperature dehumidification air-conditioning box proposed in the utility model is also provided with an "internal circulation" function, which specifically is to open a return air port on the air duct, and the air flow sent out through the air duct outlet enters the air duct again from the return air port, and a medium-efficiency filter module and a second pre-cooling module are arranged at the return air port.
