[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0024] It is understood that in related art, the air inlet of a heat pump unit is located on the side of the unit, such as the heat pump dehumidification and temperature control unit disclosed in Patent CN215836143U. The present utility model is suitable for measuring the air volume at an air inlet or outlet located on the side of a heat pump unit. Furthermore, the air inlet of a heat pump unit is provided with a finned heat exchanger, such as a condenser or evaporator. Finned heat exchangers typically have a rectangular flow cross-section, so the air inlet of a heat pump unit is also typically rectangular.

[0025] Reference below Figure 1 and Figure 2 The wind volume measuring device according to the embodiment of the present invention is described.

[0026] The air volume measuring device of an embodiment of the present invention includes a support frame 100, an air duct arranged on the support frame 100, and an air volume measuring component 250 arranged in the air duct; one end of the air duct is called a connecting end, and the connecting end is provided with a connecting seat 210, and the connecting seat 210 is used to connect to the air inlet and outlet to be measured; the air duct has a flexible section 220, and the flexible section 220 is arranged between the connecting end and the support frame 100.

[0027] In addition to the flexible section 220, the air duct also has a narrowing section 240, which is a horizontally arranged tube. The flexible section 220 is connected to the left end of the narrowing section 240. The flexible section 220 is a rectangular tube to fit the rectangular air inlet and outlet of the heat pump unit. The left end of the flexible section 220 is the connecting end. The flexible section 220 is made of a flexible material. The air volume measurement component 250 can be installed in the narrowing section 240, the flexible section 220, or other suitable locations in the air duct.

[0028] The support frame 100 can be made of channel steel. The support frame 100 includes a base, a front column and a rear column. The front column and the rear column are both vertically arranged, and the front column and the rear column are both fixedly connected to the base. The front column is arranged in front of the rear column at intervals, and the air duct is arranged between the front column and the rear column. The right end of the flexible section 220 is connected to the front column and the rear column.

[0029] When in use, the air volume measuring device is moved to the side of the air inlet or air outlet of the heat pump unit, and then the connecting end is connected to the air inlet angle or air outlet through the connecting seat 210, and the heat pump unit is started. The air volume inlet or air outlet of the heat pump unit can be measured through the air volume measuring component 250; by setting the support frame 100, the staff does not need to lift the air duct all the time during the measurement process. By setting the flexible section 220, the staff is allowed to have a certain deviation in the end position of the air volume measuring device moved by the staff. The staff can more easily connect the connecting end to the air inlet angle or air outlet, which is convenient for operation.

[0030] In some embodiments of the present invention, the air duct has a narrowing section 240, the flow area of ​​which is smaller than the flow area of ​​the connecting end, and the air volume measuring component 250 is disposed in the narrowing section 240. This reduces the volume of the air volume measuring device and facilitates handling by personnel. Furthermore, it is understood that the air volume measuring component 250 typically measures the wind speed at a specific point and then calculates the air volume based on the flow area. However, as the flow area increases, the more likely it is that the flow velocity will be uneven across the flow cross-section, which can lead to measurement errors. The present application places the air volume measuring component 250 in the narrowing section 240, which helps reduce these errors.

[0031] In some embodiments of the present invention, the narrowing section 240 is located on the side of the flexible section 220 that is away from the connection end. In this way, the narrowing section 240 and the air volume measurement component 250 will not hinder the assembly and disassembly of the flexible section 220 and the air inlet or outlet of the heat pump unit, making it easier for operators to operate.

[0032] In some embodiments of the present invention, the air volume measurement component 250 is disposed on the side of the support frame 100 facing away from the flexible section 220. This reduces the distance between the flexible section 220 and the support frame 100, resulting in a more stable structure. When the flexible section 220 is connected to the air inlet or outlet of the heat pump unit, the flexible section 220 does not shake much, facilitating operation.

[0033] In some embodiments of the present invention, the support frame 100 is provided with a plate 230, the plate 230 is provided with a first through hole, the flexible section 220 and the narrowing section 240 are respectively provided on both sides of the plate 230, the flexible section 220 is connected to the edge of the plate 230, and the narrowing section 240 is connected to the edge of the first through hole. The air duct includes a flexible flange, the plate 230, and a pipe fitting. The flexible flange includes a canvas air duct and two flanges provided at both ends of the canvas air duct. The flange on the left of the two flanges is the connecting seat 210, the canvas air duct is the flexible section 220, the flange on the right of the two flanges is connected to the edge of the plate 230 by bolts, and the pipe fitting is connected to the edge of the first through hole by welding, flange connection or other suitable connection structure. The pipe fitting is the narrowing section 240. Such a simple structure can manufacture the air duct by simply assembling conventional components, so as to facilitate the manufacture of the air volume measuring device.

[0034] In some embodiments of the present invention, a walking mechanism is provided at the bottom of the support frame 100, so that it is convenient for workers to move the support frame 100.

[0035] In some embodiments of the present invention, the traveling mechanism includes a plurality of traveling wheels 110. The number of the traveling wheels 110 can be four, and the four traveling wheels 110 are arranged in a rectangular array, which has a simple structure and is easy to set up.

[0036] In some embodiments of the present invention, the connection base 210 is a flange. The connection base 210 can be connected to the air inlet or outlet of the heat pump unit using bolts, which is easy to operate.

[0037] In some embodiments of the present invention, the flexible section 220 is a canvas air duct, which is flexible, wear-resistant, and affordable, making it suitable for long-term use.

[0038] In some embodiments of the present invention, the air volume measurement component 250 is a duct wind speed sensor. Duct wind speed sensors are easy to use, offer excellent performance, and are highly reliable. The duct wind speed sensor comprises a main body and a probe. The main body is positioned outside the narrowed section 240. The probe penetrates the sidewall of the narrowed section 240 and extends into the narrowed section 240, completing installation.

[0039] The above specifically describes the preferred embodiments of the present invention, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
