The workstation consists of a water treatment system and a set of measuring equipment for checking the parameters of water and materials used in washing machines and dishwashers testing.
The water treatment system prepares water in accordance with the requirements of EN 60734 Method B. The prepared water accumulates in storage tanks with a capacity of 1000 liters for later use in testing.
The water treatment system consists of several units:
- pre-treatment and osmosis unit,
- water cooling units,
- water heating block,
- chemical mixing and dispensing unit,
- accumulation units,
- high-pressure units to ensure constant water pressure during testing,
- control unit.
The water treatment system is connected directly to the water supply and can operate autonomously in the 24/7 mode.
Prepared water can be fed to washing machines and dishwashers by two pipes each with its own temperature. The outlet water temperature can be set on the control unit in the range of 5 to 60°C.
During the test, periodic water monitoring is required. In some cases, the control of water parameters and reference materials should also be performed after the tests. For example, measurements of the reference materials parameters should be carried out after the end of washing while testing washing machines.
The water treatment system is powered by three-phase network 400V 50 Hz. Power consumption is not more than 40 kVA.
A fully automated workstation allows performing all measurements of the energy efficiency of washing machines and dishwashers in automatic mode and generates reports and protocols in accordance with the selected test program.
The software for the control unit is written in LabView and has many user-friendly features to manage, control and monitoring of water parameters.
