Embodiment 1

[0044] Test rig for low superheat, long-span testing of compressors, including gas coolers and compressors under test 20, such as figure 1 , figure 2 , Figure 4 and Figure 5 As shown, the gas cooler includes an outer cylinder 10 and an inner cylinder 11 disposed inside the outer cylinder 10 . The gas outlet of the outer cylinder 10 is provided with an outer cylinder gas outlet joint 100 , and the liquid inlet of the outer cylinder 10 is provided with an outer cylinder liquid inlet joint 101 . The gas outlet of the inner cylinder 11 is provided with an inner cylinder gas outlet joint 110 , and the liquid inlet of the inner cylinder 11 is provided with an inner cylinder liquid inlet joint 111 . Such as figure 2 As shown, the bottom of the inner cylinder 11 is open for communicating with the interior of the outer cylinder 10 and the interior of the inner cylinder 11 .

[0045] In the example, such as figure 1 , figure 2 , Figure 4 and Figure 5 As shown, the bottom...

Embodiment 2

[0050] On the basis of Example 1, such as figure 1 , Figure 4 , Figure 5 and Figure 7 As shown, the air outlet of the compressor 20 is connected with a compressor air outlet pipe 201, and the compressor air outlet pipe 201 is connected with a measuring pipe section 202 in parallel. The measuring pipe section 202 is provided with a condensing part and a parameter measuring part. The high-pressure hot gas entering the measuring pipe section 202 from the air outlet pipe 201 becomes a high-pressure gas-liquid mixture, and the parameter measuring part is used to test the cooling capacity of the compressor 20 . The outer cylinder liquid inlet joint 101 is connected to the outlet of the compressor air outlet pipe 201 through the outer cylinder liquid inlet branch pipe 1010 , and the inner cylinder liquid inlet joint 111 is connected to the outlet of the compressor air outlet pipe 201 through the inner cylinder liquid inlet branch pipe 1110 . An outer cylinder air outlet branch ...

Embodiment 3

[0056] On the basis of Examples 1 and 2, a test method based on a test device for low superheat and long-span testing of compressors.

[0057] Such as Figure 5 As shown, when the test device is running at full load, that is, when the test environment is provided for the compressor 20 that needs the maximum cooling capacity, open the on-off valves on the liquid inlet joint 101 of the outer cylinder and the gas outlet joint 100 of the outer cylinder, and close the inlet and outlet valves of the inner cylinder. The opening and closing valves of the liquid joint 111 and the gas outlet joint 110 of the inner cylinder open the valve on the communication pipe 112, so that the heat exchange space provided by the outer cylinder 10 and the inner cylinder 11 communicates. At this time, the heat exchange that the gas cooler can provide The area is the sum of the volume of the outer cylinder 10 and the volume of the inner cylinder 11 .

[0058] The compressor 20 discharges high-pressure ...

Abstract

The invention relates to the technical field of testing devices for refrigeration and air-conditioning products, in particular to a testing device and a testing method for low superheat and large-span testing of compressors. The air outlet of the compressor is connected with the air outlet pipe of the compressor, the air outlet pipe of the compressor is connected in parallel with the measuring pipe section, and the measuring pipe section is provided with a condensing part and a parameter measuring part. The high-pressure hot gas becomes a high-pressure vapor-liquid mixture. The gas outlet of the outer cylinder and the gas outlet of the inner cylinder are connected to the air inlet of the compressor, and the liquid inlet of the outer cylinder and the liquid inlet of the inner cylinder are connected to the compressor through the air outlet pipe of the compressor and the measuring pipe section. The air outlet of the air cooler is connected; the inner cylinder is used to provide a test environment with low superheat for the tested compressor; the outer cylinder and the inner cylinder of the gas cooler cooperate to provide a large span for the tested compressor Cold test environment.

Description

technical field [0001] The invention relates to the technical field of testing devices for refrigeration and air-conditioning products, in particular to a testing device and a testing method for low superheat and large-span testing of compressors. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's quality of life, my country's refrigeration and air-conditioning industry has developed rapidly, and more and more large and medium-sized compressor products have emerged, which are widely used in industrial and commercial fields. At the same time, these large and medium-sized compressor products need to continuously improve the design, production and testing methods. Because the test method of the compressor can carry out an objective response to the whole process of its design and production, so the industry has more and more high standards for the test equipment of large and medium-sized compressors. [0003] The g...
