Description

technical field [0001] This device can not only be used for automatic measurement of important energy efficiency indicators such as dehumidification capacity and dehumidification capacity per unit power of dehumidifiers under different working conditions, but also can be used for the measurement of power, current and heating items of dehumidifiers in CCC safety certification, which belongs to the detection field . Background technique [0002] In recent years, with the improvement of people's living standards, people have begun to pay more attention to comfortable life, and dehumidifiers have also begun to enter ordinary families. Most of the dehumidifiers currently used in homes are integral dehumidifiers. [0003] With the continuous popularization of dehumidifiers, the energy saving level of dehumidifiers has become a concern of everyone. At present, many countries and regions have performance or energy efficiency standards for dehumidifiers, such as the American Energy ...

AI Technical Summary

Problems solved by technology

[0006] Need to connect the test platform: At present, most enterprises use the enthalpy difference laboratory (working condition laboratory) to test the dehumidification capacity. The enthalpy difference laboratory provides the collection of working conditions and power, and the collection of weight requires an additional electronic scale. At present, the electronic scale cannot directly match with the enthalpy difference software to realize the collection of instantaneous data, but needs to manually record the data; and then manually analyze the recorded power data of weight and enthalpy difference in the later stage to calculate the dehumidification amount per unit power;

[0007] Placement of the dehumidifier: During the test, in order to avoid excessive dehumidification of the dehumidifier, it is sometimes necessary to lead out the drain pipe of the dehumidifier. In this way, to ensure that the dehumidifier can drain normally, the dehumidifier needs to be placed in a higher position , there is generally no platform higher than the ground in the laboratory, and the appearance and size of the dehumidifier are different, so it is time-consuming to find different items to raise it each time; if the overall measurement is placed on an electronic scale, due to Vibration causes unstable readings on electronic scales and affects test results

[0008] Frequent manual operation affects the test environment: During the test, the dehumidifier and electronic scale are in the working condition laboratory. After the operation is stable, the test personnel need to enter the laboratory to record the weight. If the water tank of the dehumidifier itself is full during the test , the test personnel are required to pour out the water and re-weigh, the process is complicated, and frequent entry into the laboratory will lead to unstable environmental conditions, thus affecting the test results;

[0009] High manual error rate: Due to the need for manual operation or recording, once the tester misses the recording time, the test will be invalid and the test will be repeated, resulting in a waste of testers and laboratory resources

[0010] Special working conditions: With the continuous development of group standards, the requirements for the dehumidification capacity of dehumidifiers under different working conditions are getting higher and higher, and there are a series of special working conditions such as low temperature working conditions, high temperature working conditions, and high humidity working conditions. These often require special working condition laboratories, and most of these laboratories do not have the function of collecting power and energy. At this time, a power meter needs to be connected separately, and a separate computer is used to collect data such as power and electric energy. Manual processing, overlapping test environment and post-data processing all prolong the test cycle, resulting in waste of resources and personnel;

[0011] To sum up, the current testing method requires too much manual participation, which increases the uncertain factors in the testing process, consumes resources and personnel, and reduces the testing accuracy.
