[0016] A test device for the operating status of a PTC two-in-one compressor includes a compressor 3, an evaporator assembly 2, and a condenser assembly 4. The exhaust port ① of the compressor 3 is connected to the suction port ② of the condenser assembly 4 through a refrigerant pipeline 10. The exhaust port ③ of the condenser assembly 4 is connected to the suction port ④ of the evaporator assembly 2 through a refrigerant pipeline 10. The exhaust port ⑤ of the evaporator assembly 2 is connected to the suction port ⑥ of the compressor 3 through a refrigerant pipeline 10, forming a refrigerant circuit.

[0017] The test apparatus also includes a water tank assembly 5, a flow meter, and a circulating water pump. The condenser assembly 4 exchanges heat with the water tank assembly 5. In this embodiment, the condenser assembly 4 is placed in the coolant in the water tank assembly 5 for heat exchange, and the cooling speed of the coolant is controlled by a corresponding fan. The outlet of the circulating water pump is connected to the inlet ⑦ of the water tank assembly through the coolant pipeline 11. The outlet ⑧ of the water tank assembly is connected to the inlet ⑨ of the compressor PTC board through the coolant pipeline 11. The outlet ⑩ of the compressor PTC board is connected to the flow meter 7 and the inlet of the circulating water pump 6 in sequence through the coolant pipeline 11 to form a coolant circulation loop.

[0018] The test apparatus also includes a test bench frame 1, on which the compressor 3, evaporator assembly 2, condenser assembly 4, water tank assembly 5, flow meter, and circulating water pump are all mounted. The evaporator assembly 2, condenser assembly 4, and water tank assembly 5 are all taken from an actual vehicle.

[0020] Specifically:

[0021] 1. The technical problem to be solved by this utility model is:

[0022] The purpose is to test the operating status of the PTC two-in-one compressor.

[0023] 2. Detailed technical solution of this utility model:

[0024] 2.1 Construct a simple frame using shaped aluminum profiles;

[0025] 2.2 Construct a refrigerant circuit using the actual vehicle's evaporator assembly, condenser assembly, and piping;

[0026] 2.3 Select actual vehicle water tank assembly, flow meter, circulating water pump, quick-connect pipe interface, liquid water pipe, water tank, pressure relief injection port and other components to build water circulation loop;

[0027] 2.4 Match the high-voltage power supply and the low-voltage power supply, and connect the circuit;

[0028] 2.5 Add coolant to the pressure relief injection port to remove air bubbles, and add some coolant to the water tank;

[0029] 2.6 Refrigerant charging is completed through the interfaces of the compressor / evaporator assembly / condenser assembly;

[0030] 2.7 Once the simple test setup is complete, turn on the power, and run the compressor. By adjusting the voltage of the evaporator fan, condenser fan, water tank fan, and water pump, the test objective of the PTC two-in-one compressor can be achieved. The condenser assembly and water tank assembly can share a fan or each can be configured with a separate fan. It can control the flow rate and temperature of the coolant circulation loop (1. The flow rate of the coolant circulation loop is controlled by the circulating water pump; 2. The temperature of the coolant circulation loop is controlled by controlling the heat exchange rate between the coolant and the air through the condenser fan and water tank fan), and it can also control the suction and discharge pressure of the compressor under test (the suction and discharge pressure of the compressor is controlled by the compressor speed and the airflow of the condenser and evaporator fans). It can simulate various operating conditions and achieve the purpose of simple testing.

[0031] Work process description:

[0032] 1. Refrigerant flow direction on the refrigerant side:

[0033] Compressor discharge port → condenser assembly → evaporator assembly → compressor suction port.

[0034] 2. Coolant flow direction:

[0035] Circulating water pump → Water tank assembly → Pressure relief injection port → Compressor PTC plate inlet → Compressor PTC plate outlet → Flow meter → Circulating water pump.

[0036] In summary, the dual circulation system achieves dual heat exchange on both the refrigerant and coolant sides. By adjusting the condenser (water tank) fan and the evaporator assembly fan, the airflow is changed, and the heat exchange is adjusted to control the compressor's suction and discharge pressure and the PTC inlet temperature, thus completing the functional testing.

Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
