Refrigerator Testing
Types of Refrigerator:
Refrigerator (fridge) is a home/Commercial appliance consisting of a thermally insulating compartment/Area and a heating Zone (mechanical, electronic) shift or transfer heat from inside to its outside environment so that its inside is cooling to a temperature below the room temperature or set temperature.
Ice-Lined refrigerators are designed for storage of vaccines, pharmaceutical products, blood bag and samples etc. at a temperature range of 2°C to 8°C. They have a lining of Ice packs hence the name. For long hold-over times should there be a power failure, a PUF insulating material is provided.
Combined refrigerators consist of two more or less equally-sized compartments: a fridge compartment up above and a freezer compartment down below.
Refrigerator/ Ice-lined refrigerator/ combined refrigerator-icepack freezer for safety testing following standard are applicable:
- IEC 60335-1: Household and similar electrical appliances – Safety – Part 1: (General requirements)
- IEC60335-2-24: Household and similar electrical appliances – Safety – Part 2-24: Particular requirements for refrigerating appliances, ice-cream appliances and ice-makers.
- WHO/PQS/E03/RF03.1: Performance Specification: Ice-lined refrigerator or combined refrigerator-icepack freezer: compression cycle.
Why Require IEC/EN/WHO Tested Refrigerators?
- Refrigerator are responsible for 50% of global electricity use in the survey.
- IEC/EN/WHO standards have contributed to the development of energy efficient Refrigerators systems through the internationally relevant test Standard like IEC/EN 60335-1, IEC/EN 60335-2-24 and WHO/PQS/EO3/RF03.1 etc.
- It’s helps to find the faults in Refrigerators in the normal and abnormal conditions.
- Performance related standard improve the working performance to get better output.
What are Benefits of Testing?
- Increase use-age life of the refrigerators.
- Save money & save energy as well with using star rating product or CE certified components
- Provide faith in product
- Improve safety of the product
- Improve performance as well
- Provide safety to user
