Description

Portable automatic performance testing device for dehumidifier

Technical Field

The device can be used for automatically measuring important energy efficiency indexes such as dehumidification capacity of a dehumidifier, dehumidification capacity of unit power and the like under different working conditions, can also be used for measuring power, current and heating items during CCC (common control communications) safety certification of the dehumidifier, and belongs to the field of detection.

Background

In recent years, with the improvement of living standard of people, people pay more attention to comfortable life, and the dehumidifier also starts to enter common families. Most of the dehumidifiers currently used in homes are integrated dehumidifiers.

The constant popularization of the dehumidifier makes the energy saving level of the dehumidifier become a concern, and at present, many countries and regions have performance or energy efficiency standards for the dehumidifier, such as the standard for energy star in the united states ANSIAHAM DH-1-2008, CSA C749-2007 in canada, BSEN810-1997 in the united kingdom, etc., product energy label practice in hong kong and the national standard for dehumidifier performance are GB/T19411-2003 dehumidifier, and the national standard for household dehumidifier T/CAS342-2019 household dehumidifier published and implemented formally in 2019.

The existing dehumidifier moisture capacity test method is to put the dehumidifier into a test room with controllable environment, adjust the distance between the dehumidifier and the surrounding walls to enable the dehumidifier to meet the standard requirements, record the dehumidifier every 10min after the dehumidifier is operated to a stable state until the recorded data for 7 times meet the standard requirements, take the arithmetic mean value of the recorded data as a calculated value, collect the condensed water and weigh the condensed water.

During this test, the following problems were encountered:

need overlap joint test platform: most enterprises adopt an enthalpy difference laboratory (working condition laboratory) to test the dehumidification capacity, the enthalpy difference laboratory provides working conditions and power acquisition, an electronic scale is added for acquiring weight, most electronic scales cannot be directly matched with enthalpy difference software at present to acquire instantaneous data, and manual data recording is needed; then, manually analyzing the recorded power data of the weight and the enthalpy difference at the later stage to calculate the dehumidification amount of unit power;

the placement position of the dehumidifier: in the test process, in order to avoid overlarge dehumidification amount of the dehumidifier, sometimes a drain pipe of the dehumidifier needs to be led out, so that the dehumidifier needs to be placed at a higher position if the dehumidifier can normally drain water, a platform higher than the ground does not exist in a test room, the appearance sizes of the dehumidifier are different, different articles need to be found to be raised every time, and time is consumed; if the whole measurement is placed on the electronic scale, the reading of the electronic scale is unstable due to vibration in the working process of the dehumidifier, and the test result is influenced.

The manual operation is frequent, and the test environment is influenced: in the test process, the dehumidifier and the electronic scale are in a working condition laboratory, and need to enter the laboratory to record the weight after running stably, if the dehumidifier is full of water in a water tank of the dehumidifier in the test process, the dehumidifier needs to pour out the water and weigh again, the process is complex, and the frequent entering of the dehumidifier can cause the instability of the environmental working condition, thereby affecting the test result;

the artificial error rate is high: due to the fact that manual operation or recording is needed, once a tester misses the recording time, the test is invalid, the test is conducted again, and waste of resources of the tester and the laboratory is caused.

The special working condition is as follows: along with the continuous development of group standards, the requirements on the dehumidification capacity of the dehumidifier under different working conditions are higher and higher, and a series of special working conditions such as a low-temperature working condition, a high-humidity working condition and the like are generated, and the special working condition laboratories are often needed, most of the laboratories do not have the power and electric energy acquisition function, at the moment, a power meter needs to be independently accessed, data such as power, electric energy and the like are acquired by using an independent computer, manual processing is performed at the later stage, the test period is prolonged by overlapping test environment and data processing at the later stage, and the waste of resources and personnel is caused;

in summary, the existing testing method needs too many parts to participate in manual work, so that uncertain factors in the testing process are increased, resources and personnel are consumed, and the testing precision is reduced.
