DETAILED DESCRIPTION

[0042] In order to make the technical scheme of the utility model more clear, the utility model will be further described in detail in combination with the drawings and specific embodiments.

[0043] Embodiment 1

[0044] As Figures 1-4 , the embodiment provides an EC fan experimental equipment, which comprises a room body 1; an air inlet pipe 2, one end of the air inlet pipe 2 being located in the room body 1; a plurality of first air inlets 21 and a plurality of second air inlets 22 being respectively arranged on the two sides of the one end of the air inlet pipe 2, an area corresponding to the first air inlets 21 in the room body 1 being configured as area one 11, and an area corresponding to the second air inlets 22 in the room body 1 being configured as area two 12; a plurality of adjusting louvers 73 corresponding to the plurality of second air inlets 22; a return air pipe 3, one end of the return air pipe 3 being located in the room body 1, and the other end of the return air pipe 3 being communicated with the other end of the air inlet pipe 2; a heat pump 4 and a fan 5 being located at the communicated position of the other end of the return air pipe 3 and the other end of the air inlet pipe 2.

[0045] Specifically, in the experiment, first, the very small and very large EC fans are installed on the single-layer mounting frame 200, and the single-layer mounting frame 200 is placed in area one 11, and the medium-sized EC fan is installed on the multi-layer mounting frame 300, and the multi-layer mounting frame 300 is placed in area two 12; then, start the heat pump 4, the fan 5 and the adjusting louver 73, so that the first air inlet 21 realizes horizontal air supply, which is convenient for the hot air to uniformly pass through the EC fan on the single-layer mounting frame 200 from one side to the other side, and the second air inlet 22 realizes angle-adjustable vertical air supply under the action of the adjusting louver 73, which ensures that the EC fan on the multi-layer mounting frame 300 is evenly heated, prevents the temperature of the upper layer from being too high, and the temperature of the lower layer from being too low, and finally makes the hot air discharged from one end of the return air pipe 3, and then discharged into the other end of the air inlet pipe 2 through the other end of the return air pipe 3, so as to realize the circulation of hot air supply; in summary, the housing 1 is configured as area one 11 and area two 12, and the heat pump 4, the fan 5 and the adjusting louver 73 are used to facilitate the targeted experiment of different types of EC fans with different sizes, different installation methods and different thermal properties.

[0046] Preferably, the air inlet pipe 2 is arranged at the inner top end of the housing 1, and the return air pipe 3 is arranged at the inner bottom end of the housing 1, so as to realize the circulation of hot air in the housing 1 under the dual action of pressure and gravity; the air inlet pipe 2 is used for air inlet, and the first air inlet 21 and the second air inlet 22 are directly arranged at one end of the air inlet pipe 2, without the need to arrange branch pipes, so as to simplify the structure and reduce the cost; the number of the first air inlet 21 and the second air inlet 22 is not limited, which can be four, five, etc., and preferably four; the adjusting louver 73 is used for adjusting the air supply direction of the second air inlet 22, so as to realize the angle-adjustable vertical air supply of the second air inlet 22; in order for the staff to work in the EC fan experiment equipment of the present scheme, there is a passageway 14 between area one 11 and area two 12 of the housing 1, and in order to prevent the wiring from leaking to the passageway 14, the wiring of area one 11 and area two 12 is arranged close to the wall of the housing 1.

[0047] Further, as Figures 5-6 Further, the temperature sensing assembly 6 is arranged in the housing 1; the controller 100 is electrically connected with the temperature sensing assembly 6, the adjusting louver 73, the heat pump 4 and the fan 5.

[0048] Specifically, after the EC fan experimental equipment of the scheme is started, the controller 100 starts the heat pump 4 and the fan 5 to send hot air into the house body 1. When the temperature sensing assembly 6 detects that the temperature in the house body 1 is higher than the first preset value, the controller 100 turns off the heat pump 4 or reduces the power of the heat pump 4. When the temperature sensing assembly 6 detects that the temperature in the house body 1 is lower than the second preset value, the controller 100 starts the heat pump 4 or increases the power of the heat pump 4, so as to conveniently send hot air into the house body 1. At this time, the scheme is in the circulating hot air supply mode. The temperature sensing assembly 6 can be in the form of a thermocouple or a thermistor. The scheme can also be provided with a power supply and a frequency converter 93 which are electrically connected with the controller 100, so as to conveniently supply 24V, 110V and 380V and other power supplies for different EC fans.

[0049] Further, as Figures 5-6 , the temperature sensing assembly 6 is configured as a plurality of first temperature sensing units 61 located in the area one 11 and a plurality of second temperature sensing units 62 located in the area two 12. The first temperature sensing units 61 and the first air inlets 21 are correspondingly arranged, the second temperature sensing units 62 and the second air inlets 22 are correspondingly arranged, and the first temperature sensing units 61 and the second temperature sensing units 62 are electrically connected with the controller 100. Specifically, the first air inlets 21 and the first temperature sensing units 61 are preferably one-to-one corresponding, so as to conveniently make the targeting good.

[0050] Further, as Figure 4 and Figure 7 , the scheme further comprises: a plurality of first air valves 71 correspondingly located in the plurality of first air inlets 21; a plurality of second air valves 72 correspondingly located in the plurality of second air inlets 22; wherein the first air valves 71 and the second air valves 72 are electrically connected with the controller 100.

[0051] Specifically, the first temperature sensing units 61 are used to form a temperature monitoring area at the air supply position of the first air inlets 21, and to perform targeted temperature measurement and transmit the temperature measurement signal to the controller 100, so as to conveniently control the first air valves 71 and thus control the air supply amount of the first air inlets 21. The second temperature sensing units 62 are used to form a temperature monitoring area at the air supply position of the second air inlets 22, and to perform targeted temperature measurement and transmit the temperature measurement signal to the controller 100, so as to conveniently control the second air valves 72 and the adjusting louvers 73 and thus control the air supply amount and the air supply angle of the second air inlets 22. The forms of the first temperature sensing units 61 and the second temperature sensing units 62 can be thermocouples or thermistors, and the first air valves 71 and the second air valves 72 can be ball valves or butterfly valves.

[0052] Further, as Figures 5-6The first temperature sensing unit 61 and the second temperature sensing unit 62 are identical in structure and each include a plurality of temperature sensors 600 arranged in a linear array, the spacing between adjacent temperature sensors 600 is equal in the horizontal direction, and the spacing between adjacent temperature sensors 600 gradually decreases in the gravity direction.

[0053] Specifically, the plurality of temperature sensors 600 are used to form multi-point temperature measurement for a single temperature monitoring area and transmit a plurality of temperature measurement signals to the controller 100, the controller 100 performs weighted summation on the plurality of temperature measurement signals to construct a temperature response value of each temperature monitoring area, thereby facilitating targeted control of the air supply amount and air supply angle of the first air inlet 21 and the second air inlet 22, and the controller 100 also performs weighted summation on the temperature response values of the plurality of temperature monitoring areas to construct a temperature response value of the entire house body 1, thereby facilitating targeted control of the on-off and power of the heat pump 4.

[0054] Since the spacing between adjacent temperature sensors 600 is equal in the horizontal direction, the temperature measurement uniformity in the horizontal direction is good; since the airflow in the upper space of the house body 1 flows well and the hot air is relatively dense, the temperature difference is small, so relatively fewer temperature sensors 600 are arranged (i.e., the spacing between adjacent temperature sensors 600 is relatively large), while the airflow in the lower space of the house body 1 flows well and the hot air is relatively sparse, the temperature difference is large, so relatively more temperature sensors 600 are arranged (i.e., the spacing between adjacent temperature sensors 600 is relatively small), which not only facilitates good temperature measurement comprehensiveness in the gravity direction, but also facilitates cost reduction; the shape of the temperature sensor 600 can be thermocouple type, thermistor type, etc.

[0055] Further, as shown in FIG. 1, Figure 6 Further, the house body 1 is movably connected with a door body 13, the door body 13 is located between adjacent second temperature sensing units 62. Specifically, the door body 13 facilitates the opening and closing of the house body 1, thereby facilitating the placement of single-layer mounting racks 200, multi-layer mounting racks 300, etc. in the house body 1; due to the presence of the door body 13, one second temperature sensing unit 62 preferably corresponds to two second air inlets 22.

[0056] Further, as shown in FIG. 1, Figure 1 Further, the house body 1 is movably connected with a door body 13, the door body 13 is located between adjacent second temperature sensing units 62. Specifically, the door body 13 facilitates the opening and closing of the house body 1, thereby facilitating the placement of single-layer mounting racks 200, multi-layer mounting racks 300, etc. in the house body 1; due to the presence of the door body 13, one second temperature sensing unit 62 preferably corresponds to two second air inlets 22.

[0057] Specifically, when the temperature sensing assembly 6 detects that the temperature in the house body 1 is higher than a third preset value (temperature upper limit value), the controller 100 opens the valve 82, so that part of the hot air in the house body 1 is discharged in turn through the return air pipe 3 and the air outlet pipe 81, and when the temperature sensing assembly 6 detects that the temperature in the house body 1 is lower than the third preset value (temperature upper limit value), the controller 100 closes the valve 82, at this time, the scheme is in the hot air discharge mode, wherein the valve 82 can be a ball valve, a butterfly valve, etc.

[0058] Further, as shown in FIG. 1, the temperature sensing assembly 6 is arranged on the house body 1. Figure 1 Further, as shown in FIG. 1, the temperature sensing assembly 6 is arranged on the house body 1.

[0059] Further, as shown in FIG. 1, the temperature sensing assembly 6 is arranged on the house body 1. Figure 1 Further, as shown in FIG. 1, the temperature sensing assembly 6 is arranged on the house body 1.

[0060] Further, as shown in FIG. 1, the temperature sensing assembly 6 is arranged on the house body 1. Figure 1 Further, as shown in FIG. 1, the temperature sensing assembly 6 is arranged on the house body 1.

[0061] The above embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
