Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a variable duct desalination air conditioning unit. Background Technology

[0002] Some industrial plants and commercial buildings have high requirements for temperature, humidity, and air quality, and require air conditioning systems to ensure the continuity of industrial production, the stability of equipment, and indoor air quality and comfort. However, conventional air conditioning units can only be shut down for maintenance when they malfunction, making it impossible to control indoor temperature and humidity, which affects the continuity of industrial production and the comfort of indoor personnel.

[0003] In coastal areas, high-concentration salt mist formed by the evaporation of sea spray is common in the air. Its main components are salt particles such as sodium chloride with a particle size of 1-5 micrometers. These particles have extremely strong suspension and permeability. When these salt mists enter indoor spaces through conventional air conditioning systems, they can cause electrochemical corrosion to metal equipment and electronic components, leading to circuit board damage, contact oxidation, and decreased insulation performance. At the same time, they can corrode building structures, accelerate steel corrosion and concrete deterioration, and cause salt precipitation and discoloration on the surface of decorative materials. Long-term exposure to this environment can irritate the respiratory mucosa and eyes, induce respiratory diseases, and cause skin discomfort. Therefore, a variable duct salt mist removal air conditioning unit is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a variable duct desalination air conditioning unit.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A variable-duct salt mist removal air conditioning unit includes an outdoor unit and an indoor unit. The outdoor unit comprises a frame, a compressor, a first heat exchanger, a first heat exchange fan, and a throttling device. The indoor unit comprises an upper casing, a lower casing, a first airtight valve, a pre-filter, a salt mist removal filter, a medium-efficiency filter, a second heat exchanger, a second heat exchange fan, and a second airtight valve. The outdoor and indoor units are connected by piping, through which refrigerant flows to achieve heat exchange and regulate indoor temperature. The airtight valve in the indoor unit allows for variable duct configuration, enabling one unit to be used while the other is on standby. The indoor unit is equipped with a salt mist removal filter to filter salt mist in the air; laser dust detectors are installed before and after the salt mist removal filter to read the salt mist particle concentration.

[0010] The upper and lower housings are each equipped with a first airtight valve, a primary filter, a salt mist filter, a medium-efficiency filter, a second heat exchanger, a second heat exchange fan, and a second airtight valve.

[0011] The upper and lower boxes are made of salt spray corrosion resistant metal materials. The sides, top and bottom are filled with metal boxes with insulation material, and the middle is filled with a metal partition with insulation material. The front end of the middle metal partition is provided with a first ventilation opening and the rear end is provided with a second ventilation opening.

[0012] The first and second sealing valves are electrically operated sealing valves.

[0013] The first sealing valve is connected to a partition installed in front of the primary filter.

[0014] The second sealing valve is connected to a partition plate installed after the second heat exchange fan.

[0015] A stainless steel water receiving tray is installed below the salt spray filter, and a water guide plate is installed between the water receiving tray and the salt spray filter.

[0016] A first laser dust detector is installed between the salt spray filter and the primary filter.

[0017] A second laser dust detector is installed between the medium-efficiency filter and the second heat exchanger.

[0018] This utility model has the following beneficial effects:

[0019] This invention achieves air duct transformation by installing a sealed valve in the indoor unit, solving the problem that air conditioning units can only be shut down for repair when they malfunction. It realizes the purpose of one unit in use and one in standby. The indoor unit is equipped with a salt mist filter, which can filter salt mist in the air, purify the indoor air, prevent salt mist from corroding indoor metal and electronic components, and at the same time protect the health and safety of indoor personnel.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1 A variable duct salt mist removal air conditioning unit includes an outdoor unit 1 and an indoor unit 2. The outdoor unit 1 and the indoor unit 2 are connected by pipes through which refrigerant flows, thereby achieving heat exchange and regulating the indoor temperature.

[0030] Reference Figure 2 The outdoor unit 1 consists of a frame 3, a compressor 4, a first heat exchanger 5, a first heat exchange fan 6, and a throttling device 7. The frame 3 is made of a metal material resistant to salt spray corrosion.

[0031] Reference Figure 3 , 45. The indoor unit is divided into two independent spatial systems: an upper casing 8 and a lower casing 9. An air inlet 10 is located at the front of the indoor unit 2, and an air outlet 17 is located at the rear. Both the upper casing 8 and the lower casing 9 are equipped with a first airtight valve 11, a pre-filter 12, a salt mist filter 13, a medium-efficiency filter 14, a second heat exchanger 15, a second heat exchange fan 16, and a second airtight valve 18. A first vent 19 is located at the front of the intermediate metal partition, and a second vent 20 is located at the rear. The first airtight valve 11 and the second airtight valve 18 are electrically operated and can be opened or closed by signal feedback, thereby changing the air duct configuration. The salt mist filter 13 filters salt mist from the air. A first laser dust detector 21 is installed between the salt mist filter 13 and the pre-filter 12 to monitor the initial concentration of salt mist particles. A second laser dust detector 24 is installed between the medium-efficiency filter 14 and the second heat exchanger 15 to monitor the final concentration of salt mist particles.

[0032] Reference Figure 6 The salt spray filter 21 is installed on the partition plate, and a stainless steel water receiving tray 22 is installed below the salt spray filter 21. A water guide plate 23 is installed between the water receiving tray 22 and the salt spray filter 21 to facilitate the dripping of salt spray filtered water into the water receiving tray.

[0033] Reference Figure 7 The upper casing 8 and the lower casing 9 are two independently operating systems with two independent air ducts. The air duct switching can be controlled by opening and closing the first airtight valve 11 and the second airtight valve 18. When the system in the upper casing 8 fails and shuts down, the first airtight valve 11 and the second airtight valve 18 in the upper casing 8 close, while the first airtight valve 11 and the second airtight valve 18 in the lower casing 9 open, and the system in the lower casing 9 starts operating. This achieves the switching of air ducts and realizes the purpose of one unit in use and one in standby for the air conditioning unit.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
