High and low temperature test chamber

I. Overview of high and low temperature test chambers

High and low temperature low temperature environment simulation test cabin meets working conditions:

1, air conditioning system performance: (1) vehicle heating (-25); (2) insulation ventilation performance (35); (3) defrosting (-18 ° C); (4) defogging (-3 ° C).

2, low temperature start (-35 ° C)

3. Environmental adaptability test of the engine and various electrical appliances, electronic devices, structural functional parts, etc. in the laboratory environment

Second, high and low temperature test cabin (room) technical indicators

Name parameter requirement note

1 temperature range -40 ° C ~ 80 ° C

2 liters, cooling rate 0.5 ° C / min (with vehicle static, the whole process average)

3 temperature control accuracy ≤ ± 1 ° C (air conditioning air outlet, static no heat load);

≤±2°C (space unevenness, static no heat load);

4 humidity control range 10 ~ 95% RH (10 ° C ~ +50 ° C)

5 humidity control accuracy ± 5% RH

6 circulating air volume ≥120000m3/h

※ The function and volume of the test cabin can be customized according to different models and test standards.
