Performance Analysis Energy Efficiency Lab For Clothes Washing Machines

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.
