[0053] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0054] The present application is further described in detail below in conjunction with specific embodiments. These embodiments should not be construed as limiting the scope of protection claimed in the present application.

[0055] The heat exchange rate calculation method, device and computer equipment of the embodiments of the present application are described below with reference to the accompanying drawings.

[0056] Figure 1 is a flow chart of a method for calculating heat exchange rate according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0057] S1, obtain the operating mode of the water pump test.

[0058] The operation modes may include a summer double heat exchanger mode, a summer single heat exchanger mode, a winter double heat exchanger mode, and a winter single heat exchanger mode. Each of the above operation modes has a corresponding heat exchange rate calculation method.

[0059] S2, determine the test parameters of the water pump according to the operating mode.

[0060] The test parameters may include the state of the water inlet bypass switch and the number of heat exchangers opened. For example, the state of the water inlet bypass switch may be set to open, and the number of heat exchangers opened may be set to open two.

[0061] Specifically, the configuration information of the water pump can be detected to determine whether the configuration information matches the operation mode. If they match, the configuration information is used as a test parameter; if they do not match, the configuration information is modified to match the operation mode, and the modified configuration information is used as a test parameter.

[0062] S3, obtaining test data of the water pump corresponding to the test parameters.

[0063] Then, the test can be started to obtain test data of the water pump corresponding to the test parameters.

[0064] S4, calculating the heat exchange rate of the water pump based on the test data.

[0065] The heat exchange rate calculation method of the embodiment of the present application obtains the operating mode of the water pump test, determines the test parameters of the water pump according to the operating mode, and obtains test data of the water pump corresponding to the test parameters, and then calculates the heat exchange rate of the water pump according to the test data, thereby realizing automatic adaptation of the experimental parameters and the operating mode, automatically calculating the heat exchange rate, avoiding the influence of manual operation on the test, and improving the test efficiency.

[0066] In another embodiment of the present application, Figure 2 As shown, the heat exchange rate calculation method also includes:

[0067] S5, after acquiring the test data of the water pump corresponding to the test parameters, accumulating and updating the test data.

[0068] Specifically, the test data can be linearly corrected, and then the average value of the most recent N test data can be calculated. For example, assuming N is 100, the most recent 100 test data can be obtained to calculate the average value. Of course, there may be bad values ​​(values ​​outside the normal range) among them, so after removing the bad values, the most recent 100 test data can be selected to update the calculated data. If the bad values ​​exceed a certain number or proportion, such as more than 10 bad values, an error message can be returned and recorded in the log.

[0069] The accuracy of the test results can be improved by calculating the average value of multiple test data.

[0070] A specific embodiment is described in detail below.

[0071] The heat exchanger efficiency test operation mode of the KME system can select different operation modes by configuring the water inlet bypass switch and specific heat exchanger parameters. Figure 3 As shown, there are 4 types: summer double heat exchanger mode, summer single heat exchanger mode, winter double heat exchanger mode and winter single heat exchanger mode.

[0079] After obtaining the test parameters and node data, the heat exchange rate can be calculated to obtain the test results.

[0083] S503, judging whether the test data supports the winter operation mode. If yes, proceed to step S504; if no, proceed to step S506.

[0084] S504, determine whether the water inlet bypass switch is turned on. If it is turned on, go to step S505; if it is not turned on, go to step S506.

[0085] S505, subtract the bypass flow rate from the input value of the fluid flow rate.

[0086] S506, judging whether the test data needs to be corrected. If correction is required, proceed to step S507; if correction is not required, proceed to step S508.

[0087] S507, performing linear correction on the test data.

[0088] S508, determine whether the test calculation uses the average value. If the average value is used, proceed to step S509; if the average value is not used, proceed to step S515.

[0089] S509, update the cache.

[0090] S510, judging whether the cumulative number of test data meets the requirement for calculating the average value. If so, proceed to step S511; otherwise, return to step S501.

[0091] S511, calculate the average value.

[0092] S512, remove bad values.

[0093] S513, judging whether the number of bad values ​​exceeds the limit. If it exceeds the limit, jump to step S514; if it does not exceed the limit, jump to step S515.

[0094] S514, return an error and record a log.

[0095] S515, update calculation data.

[0096] The embodiment of the present application realizes automatic switching among the summer dual heat exchanger mode, the summer single heat exchanger mode, the winter dual heat exchanger mode, and the winter single heat exchanger mode by adopting a dedicated software algorithm, and automatically calculates the result of the heat exchange rate by adopting a method of acquiring test parameters and real-time data in real time, thereby solving the problem of manual processing of seasonal change operations and the influence on the output of test results.
