Oversized environmental test chamber for military communications vehicles
1. Inner dimension: 16m × 5.5m × 6m (length × width × height)
2. Temperature range: -65 ℃ ～ +100 ℃ temperature deviation ±2℃; humidity range: 25% ～ 98% RH
3. Humidity deviation: ＞ 75% RH + 2 ～ -3% (＞75%RH), ± 5% (≤75% RH)
4. heating time: ≥ 1 ℃ / min: -45 ℃ ～ +70 ℃, full range on average (no load); ≤ 230min: -50℃ ～ room temp with 38 tons of product load (steel vehicle)
5. cooling time: +70 ℃ ～ -45 ℃, full range on average: ≥ 1 ℃ / min (no load); ≤ 230min: room temp ～ -50℃, with 38 tons of product load (steel vehicle)
6. Load capacity (at constant temperature): (-45℃ ～ + 62℃): UUT(with 25000kg equiv alluminium, equiv area 200㎡), 65kw (heat radiation: 25kw, fan heat: 40kw) diesel engine working fresh air demand 12m³/min.
7. Structural strength: test chamber floor bearing capacity (-45℃ ～ +62℃): UUT(with equivalent aluminum 25000kg, equivalent area 200㎡) 65kW (heat radiation: 25kW, fan heat 40kW), fresh air demand for the diesel engine 12m³/min.
8. Damp-heat mode: (damp-heat process where the UUT works): damp and heat cycling (typical: 20 ～ 30 ℃/40 ～ 60℃, RH95%, temperature variation ≥ 85%), constant damp and heat (typical: 30℃～40℃，90%～98%)
