Description

Technical Field

[0001] This utility model relates to the field of marine engineering technology, specifically to a dual-fan variable frequency silent integrated air conditioner. Background Technology

[0002] Traditional bulky air conditioning systems use a large fan, which generates significant noise. A 24,000 btu cooling capacity produces approximately 65 decibels of noise, while a 48,000 btu system produces approximately 75 decibels. Since some ships require a single air conditioner to be used by two cabins, traditional systems with only one fan necessitate the installation of a T-junction at the air vent, making the system even more cumbersome.

[0003] In summary, the existing technology has the following main drawbacks:

[0004] 1. It's very noisy;

[0005] 2. Installation is inconvenient and requires additional installation procedures.

[0006] Therefore, this utility model designs a dual-fan variable frequency silent integrated air conditioner. Utility Model Content

[0007] To address the shortcomings of existing technologies, the purpose of this invention is to provide a dual-fan inverter silent integrated air conditioner. This design replaces the traditional large fan with two smaller fans, resulting in significantly reduced noise while maintaining the same airflow. For example, the noise level of a 24,000 btu cooling capacity model is reduced from 65 decibels to 55 decibels, and the noise level of a 48,000 btu model is reduced from 75 decibels to 60 decibels. The noise reduction effect of the dual-fan design is even more pronounced in larger models.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a dual-fan variable frequency silent integrated air conditioner, comprising dual fans, a DC brushless variable frequency compressor, a finned heat exchanger, and a condenser. The two air outlets of the dual fans are respectively connected to two cabins. A finned heat exchanger is provided on one side of the dual fans. The DC brushless variable frequency compressor is connected to the finned heat exchanger and the condenser respectively.

[0009] Preferably, the dual fans are either built-in or external fans.

[0010] Preferably, the external fan is located on the outside of the finned heat exchanger, and adopts a single air inlet and dual fans, which is suitable for air conditioning units with a cooling capacity of less than 24,000 btu.

[0011] Preferably, the built-in fan is located inside the finned heat exchanger and adopts a dual-inlet fan, which is suitable for air conditioning units with a cooling capacity of less than 48,000 btu.

[0012] Preferably, the finned heat exchanger adopts a copper tube and copper fin structure.

[0013] Preferably, the condenser is a shell-and-tube condenser.

[0014] The beneficial effects of this utility model are:

[0015] 1. The system uses dual fans, which is convenient for some ships that need to distribute one air conditioner to two cabins. You only need to connect the pipes directly to the two fan outlets.

[0016] 2. The traditional large fan was replaced with two small fans, which greatly reduced noise;

[0017] 3. Smaller size and more flexible layout. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments;

[0019] Figure 1 This is a schematic diagram of the external fan air conditioner of this utility model;

[0020] Figure 2 This is a schematic diagram of the built-in fan air conditioner of this utility model. Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Example 1: Refer to Figure 1 This embodiment 1 provides an externally mounted dual-fan inverter silent integrated air conditioner, including dual fans 1, a DC brushless inverter compressor 2, a finned heat exchanger 3, and a condenser 4. The two air outlets of the dual fans 1 are respectively connected to two ship cabins via pipes. A finned heat exchanger 3 is installed on one side of the dual fans 1. The DC brushless inverter compressor 2 is connected to both the finned heat exchanger 3 and the condenser 4. The dual fans 1 are externally mounted; the external fans are located outside the finned heat exchanger 3, using a single air inlet dual-fan design, and are used for air conditioning units with a cooling capacity of 24000 btu or less. The finned heat exchanger 3 uses a copper tube and copper fin structure.

[0023] The working principle of this embodiment is as follows: The refrigerant is compressed into a high-temperature, high-pressure gas in the DC brushless inverter compressor 2. The high-temperature, high-pressure gas enters the condenser 4, where it releases heat and condenses into a high-pressure liquid through heat exchange with external cooling water or air. The high-pressure liquid refrigerant is then depressurized and cooled by a throttling device (such as a capillary tube or expansion valve) before entering the finned heat exchanger 3. External dual fans 1 draw in air from the outside and blow it towards the finned heat exchanger 3 through a single air inlet. The air exchanges heat with the low-temperature refrigerant in the finned heat exchanger 3, and after being cooled, the air is piped into the two cabins through the two fan ports. Due to the dual-fan design, the airflow distribution is more uniform, and noise is significantly reduced.

[0024] The DC brushless inverter compressor 2 automatically adjusts its speed according to the cabin temperature requirements, achieving precise cooling. The dual fans 1 also support inverter control, which can adjust the speed according to the actual air volume requirements, further reducing energy consumption and noise.

[0025] Example 2: Refer to Figure 2 The difference between this embodiment and embodiment 1 is that this embodiment provides a built-in dual-fan variable frequency silent integrated air conditioner. The built-in fan is located inside the finned heat exchanger 3, and adopts a dual-inlet fan. It is an air conditioning unit with a cooling capacity of less than 48,000 btu.

[0026] In this embodiment, when two cabins need to be used, there is no need to install a T-junction structure; simply connect the pipes directly to the two fan outlets.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
