Energy Efficiency Testing Lab Temperature and Humidity Room for Washing Machines
Overview:
The washing machines performance test system consists of three parts: water supply chamber, test chamber , and control system. The equipment provides constant temperature and constant pressure water source for the test, and timely records the relevant parameters of the test process, calculates and generates test reports. The water supply device has multi water tanks, tap water is purified and input into hard water preparation tank, the hardness of the water is adjusted in a hard water preparation tank and then added to the water supply tank. In the water supply tank through heating, cooling (cooling using water-cooled chiller, coupled with cooling tower) to achieve the test temperature, water can be alternately supplied, pumped into the water supply pipeline through the pump, and then divided into two test ways in the test room for each test stations. The test water is not recycled. The water supply chamber and the test chamber are separated by an insulated storage board, and the test room is equipped with air conditioning. the ground has drainage ditch. The control cabinet is located indoors, and the test instrument is installed at the test station to collect data to the computer through networking. The water tank and the pipeline are all adopt heat preservation measures, and the water flow is continuously circulated to ensure that the water temperature fluctuation at the inlet of the laboratory test bench is not more than 0.5 °C/min during the work.

Testing Contents:
NO. | Item | Inspection Content and Requirements |
1 | Environmental Control | 6.1.1 In addition to the test specified in the test environment, the type test should be at a temperature of (23 + 2), with a relative humidity of (60~70) %, no outside air, no strong sunlight and other thermal radiation. |
2 | Water Quality | Water quality: The hardness of test water is (40-60) X10-6. |
3 | Water Temperature Control |
6.1.4 The water temperature of the water inlet of the washing machine with heating device is (15±2) °C; 6.1.5 The water temperature of the inlet of the drum washing machine without heating device is (50±2) °C; 6.1.6 The water temperature of the inlet of the pulsatory / stirring washing machine without heating device is (30±2) °C; 6.1.8 Woo washing process without heating device drum washing machine washing water temperature (40 ± 2) ° C; |
4 | Electricity Consumption Calculation | 5.13 Electricity consumption: Washing machine for washing performance test. The unit washing capacity should be no more than the specified value in Table 4; |
6.3.1 The washing test measures the electricity consumption at the same time, and the electricity consumption is calculated according to formula (1) E=E1/m. | ||
5 | Water Consumption Calculation | 5.14 Water consumption: washing machine washing performance test the whole process of unit washing capacity water consumption should not be greater than the specified value of table 5.; |
The washing test measures the amount of water at the same time, and the water consumption is calculated as W=W1/m according to the formula (3). | ||
6 | Water Supply Pressure Control | 6.1.7 The pressure from the inlet of the full-motion washing machine is (0.24±0.02) °C. |
7 | Speed Measurement | 5.17 Dehydration speed: In the nameplate, logo, or the instruction manual, the dehydration speed of the washing machine shall be measured. Under the rated load, the measured dehydration speed shall not be lower than 92% or 100 rpm of the indicated value. The two shall take a smaller value and the duration at that speed. Should not be less than 60S. |
8 | Temperature Rise Measurement | Measuring the temperature of the fuselage, a total of six channels. |
9 | Ground Safety Inspection | Connect and disconnect the ground wire and check whether the sample is electrified or not working properly. |
10 | Power Supply Commutation Detection | When the power source L pole is reversed from the N pole, the sample is detected to have a charged or abnormal working phenomenon. |
11 | Overvoltage or Undervoltage Test | Adjust the output voltage higher than the rated value to determine whether the protection measures of the transformer and related circuits are reliable when abnormal conditions occur; |
Adjust the output voltage below the rated value to detect the minimum normal operating voltage of the washing machine. |
Structure:
The washing machine performance test system consists of constant temperature chamber, water purification device, raw water storage tank, soft water storage tank, hard water preparation chamber, cold water supply tank, hot water supply tank, test station and control and data acquisition system.
