Product Usage	The equipment can be widely used in high and low temperature tests, damp heat tests, and high-performance identification tests on electronic and electrical products , vehicle-mounted assemblies, components, and materials. It can simulate the adaptability of electrical and electronic products, vehicle-mounted equipment, and instruments to environmental conditions under changing temperature and humidity, and conduct quality and reliability tests on test products. It can provide high temperature, low temperature, humidity and other environmental simulation conditions to complete the following environmental tests or reliability tests: high temperature/low temperature storage test, high and low temperature cycle test, high and low temperature humidity and heat alternation test, constant humidity and heat test, etc.
2.Structural dimensions
Structural form		It adopts an assembled structure with the bottom directly touching the ground, allowing for walk-in access
Nominal volume		Effective volume of inner tank: 6m³
Internal dimensions (mm)		Effective volume : W2000H2000D1500mm
External dimensions (mm)		chamber external dimensions: approximately W2300H2380D3100mm (excluding top fan protrusion ) Size and quantity are subject to final design
Gross weight		About 1600kg
3. Temperature
Temperature range		-40℃～ + 160℃
Temperature uniformity		≤2℃ (no load)
Temperature fluctuation		≤ 0.5℃ ( no load)
Temperature deviation		≤± 2.0℃ (no load )
Heating rate		-40℃ ～+ 85℃, average ≥1℃/ min ( no load )
Cooling rate		+85℃～ -40℃, average ≥1℃/ min ( no load )
Rate		Temperature change rate can be set and controlled
Illustrate		above heating and cooling rates are measured at the air outlet under room temperature of 25°C, normal pressure and no-load conditions . The temperature change rate is determined in accordance with IEC-60068-3-5 , and the cooling rate is evaluated within 80% of the full cooling range. Water-cooling equipment can be used when the cooling water flow is insufficient or the water temperature is too high, but the low-temperature cooling rate will be affected ; it is forbidden to open the box door for a long time during low-temperature operation, otherwise it will cause malfunction of the box and refrigeration system, and even damage the compressor.
4. Humidity
Humidity range		20%～ 98%RH (temperature range: + 20℃～+85℃) ( No active heat load) Temperature and humidity range chart
Humidity deviation		≤75%RH , ≤ ± 5%RH (No load) >75%RH , ≤ +2, -3%RH (No load)
Humidity fluctuation		≤± 2 %RH (no load)
Humidity resolution		±0.1%RH
Illustrate		The above performance parameters are tested under the conditions that meet the equipment environment requirements according to the methods specified in GB/T5170.2-2017 and GB/T5170.5-2016, and meet the national standard "JJF1101-2019" Water-cooled equipment can be used when the cooling water flow is insufficient, the water temperature is too high, or the ambient temperature is too high . However, the low-temperature range and cooling rate will be affected. During low-temperature operation, the door should be kept closed as little as possible to prevent evaporator icing. If the door needs to be opened during low-temperature operation, it should be closed as quickly as possible .
Equipment noise		≤ 75 dB, the measurement point is 1m away from the center axis of the front of the equipment (perpendicular to the front of the equipment), the height from the ground is 1/2 of the equipment height, but the maximum height from the ground is not more than 1.5m, and the minimum height is not less than 1m. The measurement is also carried out at 1m around the compressor, and the requirement is that the noise level around the compressor is ≤ 78dB
5. Control method
System Control		Refrigeration system: mechanical compressor refrigeration Dehumidification system: mechanical compression dehumidification Refrigeration unit cooling method: water cooling
Controller		7 -inch color resistive touch screen programmable controller (independently developed controller, touch screen + PLC)
