Abstract
Description
Technical Field
[0001] This utility model relates to the field of fan coil air conditioning technology, and in particular to a fan coil assembly with a combined guide plate. Background Technology
[0002] Fan coil units (FCUs) are an important component of terminal equipment in air conditioning systems. They achieve heat exchange through internal coils. When heating is needed, a hot refrigerant (refrigerant or water) flows through the coils, and a fan blows indoor air across the coils, heating the air before it is delivered into the room, raising the indoor temperature. In cooling mode, a cold refrigerant flows through the coils, and a fan blows indoor air across the coils, cooling the air and removing some water vapor, lowering the indoor temperature and humidity.
[0003] When air flows through the coil at a certain speed, it can exchange heat more fully with the refrigerant (refrigerant or water) in the coil. At the same time, the uniform distribution of airflow through the entire coil can improve heat exchange efficiency, ensure uniform indoor temperature, improve air quality, save energy, and reduce noise and vibration, thereby improving the overall performance of the air conditioning system and indoor comfort.
[0004] In the prior art, Chinese patent (CN201926041U) provides a fan coil unit, which specifically includes two fans, a coil and two air inlets installed in the unit body, and a DC brushless motor fixed on the fans. The DC brushless motor drives the two fans through a rotating shaft, and a guide plate inclined outward is provided on one side of each air inlet. The guide plate can guide part of the airflow to the side of the air inlet, increase the airflow distributed on the coil located on the side of the air inlet, and make the airflow distribution through the entire coil more uniform. However, this structure does not consider the turbulence and vibration generated when the airflow passes through the fan coil unit, and the equipment will emit a lot of noise when it is running, affecting the comfort of use.

[0009] Compared with existing technologies, the fan coil unit assembly with a combined guide plate described in this utility model can improve the uniformity of airflow distribution in the fan coil unit, enhance heat exchange efficiency, reduce operating noise, and achieve energy-saving effects.

[0019] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings. Attached Figure Description
[0020] Figure 1 This is a schematic diagram of the structure of the fan coil unit assembly of this utility model;
[0021] Figure 2 This is a schematic diagram of the structure of the guide plate of this utility model. Detailed Implementation
[0022] The following describes the utility model in detail with reference to the accompanying drawings.
[0023] like Figure 1 As shown, a fan coil unit assembly of this utility model includes a coil module 100, a fan module 200, and a guide plate 300. The coil module 100 is used to provide heat for heating or cooling for cooling the air. The fan module 200 is disposed outside the coil module 100 and is used to generate the power for airflow, so that external air flows into the coil module 100. The guide plate 300 is fixedly disposed inside the coil module 100 and is disposed in the middle of the airflow channel from the fan module 200 to the coil module 100, and is used to control and guide the flow direction and speed of the air flowing from the fan module 200 into the coil module 100.
[0024] The coil module 100 includes a housing 110, a coil 120 fixedly installed within the housing 110, and a coil air inlet 130 and a coil air outlet (not shown) formed on the housing 110. The coil air inlet 130 is located on the windward side of the coil 120, and the coil air outlet is located on the leeward side of the coil 120, opposite to the windward side. Air enters the coil module 100 through the coil air inlet 130, exchanges heat with the working fluid in the coil 120, and then flows out through the coil air outlet.
[0025] Specifically, there are no specific restrictions on the shape of the coil air inlet 130.
[0026] To disperse airflow and expand its coverage, the coil air inlet 130 includes a first coil air inlet 130A and a second coil air inlet 130B. The spacing between the first coil air inlet 130A and the second coil air inlet 130B ensures that the air entering from the first coil air inlet 130A and the air entering from the second coil air inlet 130B can fully cover the windward side of the coil 120.
[0027] The fan module 200 includes a motor 210, a fan 220, and a fan inlet (not shown) and a fan outlet 240 formed on the fan 220. The motor 210 is connected to the fan 220 via its output shaft 211, and the fan outlet 240 is coupled to the coil inlet 130. The rotation of the motor 210 via the output shaft 211 drives the fan blades (not shown) of the fan 220 to rotate, causing air to flow from the outside through the fan inlet, the fan outlet 240, and the coil inlet 130 before flowing into the coil 120.
[0028] In one embodiment, if the coil module 100 is provided with a first coil air inlet 130A and a second coil air inlet 130B, then the corresponding fan module 200 includes two fans 220, namely a first fan 220A and a second fan 220B. The first fan outlet 230A of the first fan 220A is coupled and connected to the first coil air inlet 130A, and the second air outlet 230B of the second fan 220B is coupled and connected to the second coil air inlet 130B.
[0029] In one embodiment, the same motor 210 can be used to drive the first fan 220A and the second fan 220B. The motor 210 is positioned between the first fan 220A and the second fan 220B, and output shafts 211 are respectively provided on both sides of the motor 210. The first fan 220A and the second fan 220B are driven by the output shafts 211 on both sides. In some embodiments, motors 210 are respectively configured for the first fan 220A and the second fan 220B.
[0030] A baffle plate 300 is installed on the coil air inlet 130 and is located on the side close to the coil 120. The projected area of the baffle plate 300 on the plane where the coil air inlet 130 is located is the same as the area of the coil air inlet 130.

In some embodiments, if the guide plate 300 is directly or through some common connection structure (such as bolt connection) connected to the body 110 near the coil air inlet 130 to cover the coil air inlet 130, then its edge shape can be arbitrarily selected.
[0033] The guide plate 310 can be a straight plate, a curved plate, etc., and its shape is not limited in this application;
[0034] The speed guide plate 310 can be composed of multiple plates or a single plate, and the composition and quantity of the plates are not limited in this application;
[0035] The ventilation hole 311 can be a circular hole, a polygonal hole, etc., and its shape is not limited in this application;

[0037] Furthermore, in order to improve the uniformity of airflow distribution within the coil module 100, the guide plate 300 also includes a guide plate 320, which is connected to the speed guide plate 310 at a certain angle; the guide plate 320 is arranged along the edge of the speed guide plate 310, and a number of hollow windows 321 are evenly distributed on the guide plate 320.

[0046] Furthermore, in order to better realize the guiding effect of the baffle plate 330 on the external air flowing from the fan module 200 into the coil module 100, the speed guide plate 310 is parallel to the plane of the coil air inlet 130, and the air guide plate 320 is symmetrically distributed relative to the speed guide plate 310.
