Description

Technical Field

[0001] This utility model relates to the field of air conditioning energy-saving equipment technology, and in particular to a box-type wet film energy-saving device and an air-cooled air conditioning unit. Background Technology

[0002] Air-cooled air conditioning units are often placed on rooftops or inside building louvers. To improve cooling efficiency and reduce energy consumption, current practices involve installing a high-evaporation-capacity wet film directly on the air inlet of the unit. When hot outside air passes through the wet film, the water in the film evaporates rapidly, lowering the outside air temperature. This can reduce the temperature of the air entering the air-cooled unit by 10-20°C, achieving energy savings. However, installing the wet film directly on the air inlet can damage the unit, is difficult to modify, and limits the air intake area, resulting in low heat exchange efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a box-type wet film energy-saving device and an air-cooled air conditioning unit in response to the existing technical status. This utility model is not completely attached to the air conditioning unit, which avoids damage to the air conditioning unit caused by adding wet film components and also reduces the difficulty of modification. At the same time, the air inlet surface of this utility model is not limited to the air inlet of the air conditioning unit, so the air inlet area is larger and the heat exchange efficiency is higher.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Example 1: Please see Figures 1-5 As shown, a box-type wet membrane energy-saving device includes an outer cover 1 and several wet membrane components.

[0017] The outer cover 1 is a square shell structure with an open bottom. Each side of the outer cover 1 is provided with an air inlet window 101. The number of air inlet windows 101 is determined according to the external dimensions of the air conditioning unit. The top surface of the outer cover 1 is provided with an air outlet window 102. The number of air outlet windows 102 is determined according to the number of air outlets on the air conditioning unit.

[0018] Preferably, sealing rings 5 ​​are provided at the corresponding locations on the inner top surface of the outer cover 1 and each air inlet window 102, as well as at the openings on the bottom surface of the outer cover 1. According to the above design, during installation, the outer cover 1 is placed on the air conditioning unit, ensuring that the air outlet windows 102 on the outer cover 1 correspond to the air outlets of the air conditioning unit. Based on the sealing rings 5, the outer cover 1 and the mounting surface of the air conditioning unit can be sealed and connected, and the air outlet windows 102 on the outer cover 1 correspond one-to-one with the air outlets of the air conditioning unit.

[0019] It should be noted that sealing sealant can also be used to ensure a sealed connection between the outer cover 1 and the mounting surface of the air conditioning unit, and the air outlet windows 102 on the outer cover 1 correspond one-to-one with the air outlets of the air conditioning unit. The choice between sealing ring 5 and / or sealing sealant depends on the site conditions.

[0020] The wet membrane assembly includes a wet membrane plate and its water supply system. Each air inlet window 101 on the outer cover 1 is equipped with a wet membrane plate. The water supply system includes a water tank 7, a water distributor 8, a water pump 10, and a water supply pipe 9. The water tank 7 and the water distributor 8 are arranged above and below the corresponding wet membrane plates, respectively. The water pump 10 is installed in the water tank 7, and the water supply pipe 9 connects the water pump 10 and the water distributor 8. In the water supply system, the water tank 7 (water pump 10) → water supply pipe 9 → water distributor 8 → wet membrane plate → water tank 7 forms a water cycle.

[0021] The water supply system also includes an electrical control cabinet 11, which is electrically connected to the water pump 10 and is used to control the operating status of the water supply system. When the water supply system is working, the wet film plate is saturated with water; when the water supply system stops working, the wet film plate is dehydrated.

[0022] Since the operation of the wet film plate causes water loss during circulation, the water tank 7 is connected to the water source through the water supply pipe 11, and a float valve is installed at one end of the water supply pipe 11 inside the water tank to achieve automatic water replenishment. The water source is generally tap water.

[0023] For the wet film assembly, one preferred embodiment is that the wet film panel includes a support frame 2 and a wet film body 3 fixed within the support frame 2, with the support frame 2 detachably connected to the air inlet window 101 on the outer cover 1. According to this design, the wet film panel can be quickly disassembled, facilitating maintenance of the air conditioning unit.

[0024] A further preferred embodiment is that the support frame 2 is provided with a handle 4, which allows for better assembly and disassembly of the wet film plate.

[0025] For the wet film assembly, a second preferred embodiment includes an observation window 6 fixed within the support frame 2, located at the bottom of the wet film assembly. According to this design, the conditions inside the water tank 7, such as water level information, can be observed through the observation window 6.

[0026] In this embodiment, for example, the wet membrane body 3 is a mixture of wood and fiber, and adopts an ant-hole mesh structure. The water evaporation efficiency is increased by more than 36% compared with ordinary materials. The ant-hole mesh structure also reduces the resistance to air passage, allowing the airflow to pass through the wet membrane body 3 easily. At the same time, antibacterial ingredients are added to the wet membrane body 3, which can effectively inhibit bacterial growth and have a longer lifespan.

[0027] In addition, the wet film energy-saving device also includes a temperature sensor 12 and a humidity sensor 13, both of which are electrically connected to the electrical control cabinet 11 of the water supply system. Pre-set parameters are configured such that when the temperature monitored by the temperature sensor 12 is not greater than a first preset value and / or the humidity monitored by the humidity sensor 13 is not less than a second preset value (under different climatic conditions), the electrical control cabinet 11 automatically cuts off power, causing the water supply system to stop working; conversely, when the temperature monitored by the temperature sensor 12 is not greater than a first preset value and / or the humidity monitored by the humidity sensor 13 is not less than a second preset value, the electrical control cabinet 11 remains powered on, allowing the water supply system to continue operating, thereby saving energy.

[0028] Example 2: Please see Figures 1-5 As shown, an air-cooled air conditioning unit includes an air conditioning unit and the box-type wet film energy-saving device in Embodiment 1. The outer cover 1 is installed on the air conditioning unit and is sealed to the mounting surface of the air conditioning unit. The air outlet window 102 provided on the outer cover 1 is connected to the air outlet of the air conditioning unit one by one.

[0029] Among them, the electrical control cabinet 11 of the water supply system is also electrically connected to the air conditioning unit, and the start and stop of the air conditioning unit is related to the power on / off of the electrical control cabinet.

[0030] In the above technical solution, preferably, the distance between the air inlet of the air conditioning unit and the wet film body 3 in the wet film plate is not less than 150mm. By increasing the distance between the air inlet of the air conditioning unit and the wet film body 3 in the wet film plate, water in the wet film body 3 is prevented from splashing onto the air inlet of the air conditioning unit, thus preventing corrosion of the fins installed in the air inlet of the air conditioning unit.

[0031] In summary, this invention fully encloses the air conditioning unit with an outer casing 1. Air enters through the air inlet windows 101 on each side of the outer casing 1, is cooled by the wet film plate installed in the air inlet window 101, and then completes the subsequent heat exchange process before exiting through the air outlet window 102 on the top surface of the outer casing 1. Compared to existing technologies, this invention is not completely attached to the air conditioning unit, avoiding damage to the air conditioning unit caused by adding wet film components and reducing the difficulty of modification. Furthermore, the air inlet surface of this invention is not limited to the air inlet of the air conditioning unit, resulting in a larger air inlet area and higher heat exchange efficiency. Of course, the above are only preferred embodiments of this utility model and are not intended to limit the scope of application of this utility model. Therefore, any equivalent changes made to the principle of this utility model should be included within the protection scope of this utility model.
