Vehicle Altitude Environment Test Chamber

Model

CZ2-AQH-945m³E-WR (Customizable)

Test Chamber Size

W7000*D18000*H7500mm

Temperature Range

-55℃~+75℃ (static, normal pressure) / -45℃~+55℃ (low pressure)

Humidity Uniformity/Fluctuation/Deviation

≤2℃ (static test, atmospheric pressure) / ≤±1℃ (static test, atmospheric pressure) / ≤±2℃ (static test, atmospheric pressure)

Heating/Cooling Time

≥0.5℃/min (-40℃ to +60℃, no load, normal pressure, average)

Humidity Range

10%～95%RH (temperature range 20℃~60℃)

Pressure Range

Atmospheric pressure ~50kPa [-45℃~+55℃] Altitude approximately 5500 meters /*Note: Cool down to the set value and stabilize before reducing pressure.

Buck Rate

≥3kPa/min

Fresh Air System

Under normal pressure mode: minimum dew point temperature -40℃, minimum airflow not less than 2000 m³/h; in environments above 25℃, minimum airflow not less than 5000 m³/h.

Under low pressure mode: minimum dew point temperature -40℃, minimum airflow not less than 2000 m³/h; in environments above 25℃, minimum airflow not less than 5000 m³/h.

At an altitude of 5500m, the oxygen content in the air is approximately 10.4%.

Fresh Air System

When the oncoming fan inside the cabin is not running, ensure that the wind speed at the dynamometer placement position is ≤1.7m/s;

When the in-cabin frontal fan is running, the maximum air velocity at the fan outlet is 120 km/h, the area of the in-cabin frontal fan outlet is 2.0*1.2 m, and the maximum air volume is approximately 288,000 m³/h.

Wind Ppeed

288,000 m³/h

Controller

Industrial-grade 10-inch color resistive touchscreen programmable controller (independently developed controller, industrial host + touchscreen + PLC); equipped with industrial computer and control software.

Protector

Features include compressor overload and overheat protection, heater over-temperature protection switch, system overcurrent protection device, over-temperature protection, fan motor thermal overload protection, leakage protection, cooling water shortage and undervoltage protection, humidifier dry burn protection, harmful gas alarm function, smoke alarm function, flame detection alarm function, and exhaust gas and harmful gas protection and monitoring functions.

Personal Protective Equipment

Eyeglasses, protective clothing, gloves, face shields, etc.; portable oxygen cylinders, emergency call walkie-talkies, SOS flashlights, etc.; clearly visible warning signs and instructions for use of safety protective equipment; real-time security monitoring video.

Protection Requirements

Personnel operation is unrestricted in environments ranging from -40℃ to 60℃.

Life Safety Protection System

1. Equipped with a ventilation system (real-time monitoring of oxygen levels inside the chamber to determine the amount of fresh air intake).

2. Equipped with emergency stop buttons inside and outside the chamber; pressing the button replenishes air and prevents personnel injury.

3. Equipped with a safety hammer for the observation window during a powerful blast.

4. Equipped with protective gear for entering the chamber, such as safety goggles, gloves, face masks, thermal clothing, portable oxygen cylinders, emergency call intercoms, and SOS flashlights.
