Below you will find the spec. for environmental performance test room for refrigerator , please add the required measurement equipments for measuring the temperature by time (12 measuring points) for each refrigerator & the power consumption for each REF for your quotation.
Also please Let us know your previous experience for this subject.
Thank you in advance and best regards,
A – Testing conditions:-
1 – Temperature 0 ~ 50 cº ± 0.3 cº
2 – Humidity 30% ~ 95% ± 2.5% (at + 10 cº ~ +35 cº, DP+8 cº).
3 – Cooling down speed 20 cº → 0 cº less than 60 min with no load time.
4 – Heading up speed 20 cº → 50 cº less than 60 min with no load time.
Note:-
- Above numerical value assumes it one point of precision with the room temperature sensor.
The sensor for temperature control will be at the place of blowing the wind.
- Defrosting cycle starts at room temperature under 10 cº (increase temperature with in 10 cº in defrost).
5 – Temperature gradient of distribution
±0.5℃±5%, with no load time
Except 0.5 m from floor , and wall and ceiling diffuser panel
6 – Velocity
less than 0.25m/sec, Up condition is excepted for 500mm distance from ceiling and walls and ceiling diffuser panel of the test room.
B – Insulated panel and doors:-
1 – Outside dimension W 4,900 × D 7,300 * H 3,700
2 – Inside dimension W 4,750 × D 6000 * H 2,700
3 – Insulation 75mm thickness rigid polyurethane foam
4 – Finish 0.5mm thickness colored steel plate for external walls and ceiling and for internal walls stainless steel 0.8mm thickness for floor aluminum checker plate 3mm thikness

6 – Window W 300 × H 300 Heat light pair glass
7 – Diffuser Perforated aluminum plate covering ceiling
8 – Air inlet W 600 × H 200
C – Testing load:-
Refrigerator 300 w * 6 = 1800 W
Fluorescent lamp 32 w* (2 ~ 6) = 384 W
Incandescent lamp 100 W ~ 2 = 200 W
