Model: NL-ZLYL-1
The problem
Appliances charged with R290, R32 or R600a must be tested against simulated leakage scenarios under the standard. Without a controlled leakage-test environment - where leak points can be placed, concentration sampled and ventilation verified - the test is neither repeatable nor safe, and certification queues simply lengthen.
Capability
The room is built as one line: enclosure - leak - sampling - interlock. The enclosure is sealed and ventilated to the standard clauses, and simulated leak points are placed along the sample refrigerant circuit and adjusted per model. After release, flammable-refrigerant concentration probes sample continuously, so the concentration distribution and dilution process are fully recorded. Flammable gas detection, alarm devices and forced ventilation are interlocked: any point over limit trips the ventilation and the test stays under control throughout. Air-conditioning units (R290/R32/R1270) and refrigerator units (R600a) share one room; changing model only means repositioning leak points and sampling, with no second construction. Enclosure, sampling lines, ventilation and electrics are delivered complete as a turnkey project.
Applicable standards
Built to GB 4706.32-2012 Safety of household and similar electrical appliances - Particular requirements for heat pumps, air-conditioners and dehumidifiers, clauses 22.107, 22.108 and 22.109, and the corresponding clauses of GB 4706.13-2014 for refrigerating appliances; refrigerant, sampling and ventilation parameters follow the sample specification.
