As shown in fig. 1, the present invention is an air conditioning system performance testing apparatus 100. The air conditioning system performance testing apparatus 100 includes an air control unit 110, a component arrangement unit 120, and a signal control unit 130. The air control unit 110 is configured to adjust air flow at a specific temperature, humidity, and speed required by the test, so as to complete simulation of a system working environment; the component arrangement unit 120 is a device for installing relevant components of the air conditioning system, and is used for simulating the three-dimensional spatial relationship among air conditioning parts according to the actual conditions of different vehicle types; the signal control unit 130 controls the operation states of the respective components of the air conditioning system in a unified manner, and controls the devices of the air control unit 110 to operate cooperatively.
In one embodiment of the present invention, the air control unit 110 may include at least two air handling units 111. As shown in fig. 2, the air control unit 110 may include an air supply unit 114, a blower 113, an air flow path 112, an air handling unit 111, a return air unit 117, and a refrigerating unit 115 and a heating and humidifying unit 116 associated with the air handling unit 111. As can be seen from the figure, the air processing unit 111 is arranged in front and provides a test environment for the test piece 201 in an air supply manner, so that the accuracy of the simulation can be improved. The air supply unit 114 can use a conventional standard nozzle and deflector design, so that the air supply amount and the air outlet are uniform.
As described above, the air control unit 110 may flexibly include at least two air processing units 111 as needed. In another embodiment of the invention the air handling unit is designed to be semi-enclosed. As shown in fig. 2, the refrigerating unit 115 and the heating and humidifying unit 116 shown therein may provide both refrigeration and heating and humidification for other air handling units (not shown, which may for example be in the direction indicated by the dashed lines), whereby the space of the air control unit 110 is further reduced, reducing the energy consumption in case of a reduced air handling capacity requirement.

As described above, the component placement unit 120 is used to simulate the state of each component in the entire vehicle, into which each component can be mounted according to the coordinates of the component on the original vehicle. For example, the component placement unit 120 may be a flexible rack that may have components of a vehicle air conditioning system, such as a condenser, a cooling fan, a compressor, and an air conditioning cabinet assembly, disposed therein. Further, alternatively, the air control unit 110 and the signal control unit 130 may also be disposed therein.
Fig. 4 is a schematic diagram of a component arrangement unit of an air conditioning system performance testing device according to an embodiment of the present invention, and as shown in fig. 4, the component arrangement unit 120 employs a slide rail type support, and the overall size of the support can cover the size of a common vehicle, and the size of a space can be converted by using the slide rail. For example, the component placement unit 120 may include one or more movable platforms 122, on which a rack composed of slide rails 121 on which the test pieces 201 or 202 can be mounted is disposed. The movable platform may be provided with a power supply unit 123 and optionally a signal control unit 130 inside, and the air control unit 110 may be selectively disposed near the test piece. As an example, the compressor 221 as a test piece may be disposed at a position as shown in the drawing, and the corresponding compressor driving unit 222 is disposed in the movable platform.
Referring now to fig. 5, it shows a schematic diagram of the measurement signal collection of the signal control unit of the air conditioning system performance testing device according to the embodiment of the present invention.
