2024/4/9 ~ 2024/4/23
Description
A. Technical index:
1. Power: 380V, 3-, 50/60HZ 110A
2. Temperature range: 50°C~120°C
3. Humidity range: 20%~95% RH
4. Accuracy: 1) temperature ± 0.3°C;2) humidity ± 2.5% RH
5. Uniformity: 1) temperature ± 2.0°C;2) humidity ± 3.0% RH
6. Uniformity test: measured at T=85°C, RH=85%; set 9 points for temperature measurement and 2 points for humidity.
7. Inner wall is above 50 cm; within 20 min after temperature/humidity meets the setting value, the distribution uniformity of temperature/humidity can meet the aforesaid requirement.
8. Temperature descending speed (idle run): no less than 3°C/min. Temperature ascending speed (idle run): no less than 3°C/min.
9. Sample load 400kg: temperature rise – no less than 2.0°C /min; in the range of -40°C ~ +85°C.
10. Temperature down-no less than 2.0°C/min; in the range of -40°C ~ +85°C.
11. Humidity: follow IEC 61646-10.12 to make wet refrigeration test; if temperature rises up for 100°C per minute, when 85°C is reached, wait for 10 min. and humidity shall reach 85%RH ± 5%RH.
12. Dew point temperature range: 10°C to +85°C
13. Test space: 200 x 250 x 280 (W x H x D) cm double door, outer chamber size: 220 x 290 x 430 (W x H x D) cm
14. Accept customized order.
B. Itemized Introduction
Material Applied:
1. Inner/outer wall materials: apply SUS#304 plate.
2. Insulation material: imported high-strength PU foamed insulation material.
3. Condensate-proof parts: use K-type tube’s heating energy and membrane-type electrical heatig wire to prevent condensate.
Control System: apply OYO U8256; the RS232 interface can connect to PC and perform setting of temperature curveand temperature recording during test run. The touch-type T.F.T. LCD digital PLC or equivalent can perform 1200-point mode.
Refrigeration system: use imported power-saving closed-type compressor.
