Programmable constant temperature and humidity chamberMainly simulating reliability temperature and humidity conditions, it can provide users with constant high temperature, constant low temperature, high and low temperature alternation, temperature and humidity during product testing, meeting the testing needs of various industries and providing protection for improving product quality for users. There are different installation site requirements for different devices.

1、 Power supply (according toProgrammable constant temperature and humidity chamberDepending on the maximum power)

1.power cord：It is recommended to choose a minimum of3×6 mm2＋2×4 mm2Rubber sheathed copper core power cord (reference for users when purchasing power cords)

2.Grounding requirements：Grounding resistance ＜4ΩIndependently grounded, using a three-phase five wire AC power supply (strictly prohibited from mixing neutral and neutral)

3.stability ：Voltage:380V±10%Frequency:50Hz±2%

4.Wiring method：Trench wiring or bridge wiring

5.distribution box：The specifications of the air switch in the distribution box meet the maximum current of the equipment.

2、 Water source:

1.Humidification water：

Water Quality:Tap water meets the requirementsGB 5749-1985Sanitary standards for drinking water: flow rate≥200kg/h, pressure0.1MPa～0.25MPa

water consumption: RequiredBased on the temperature and humidity achievedTest conditionsDifferent anddifferent

2.coolingwater towerWater related requirements（Suitable for water-cooled equipment）

Water temperature:5℃≤water temperature≤28℃Can meet all technical specifications;28℃<Water temperature<33℃Can be used normally (cooling time may vary);

trafficAccording to different sizesProgrammable constant temperature and humidity chamberrequirement

Pipe diameter:According to the requirements of programmable constant temperature and humidity test chambers of different sizes

Stress0.3MPa～0.6MPa

Inlet and outlet water pressure difference:≥0.2MPa

water quality：satisfyGB50050-1995Design Specification for Industrial Circulating Cooling Water Treatment

3、 Land occupation requirements:

1. There is no strong vibration around the equipment; The ground is flat and well ventilated.

2. There is no strong electromagnetic field around the equipment; No flammable, explosive, corrosive substances or dust.

3. Leave appropriate space for use and maintenance around the equipment

4、 Environmental requirements:

Temperature requirements:5～25℃ ensures optimal performance,25～35℃ can operate normally

Humidity requirements:≤85％RH

Pressure requirement:86KPa～106KPa

Electromagnetic environment: There is no strong electromagnetic radiation source nearby

Site drainage: It is best to have a drainage floor drain next to the test chamber

When the test chamber is not in use, the storage environment of the test chamber should be maintained at all times0℃；

If the storage environment is less than0At ℃,For water-cooled test chambers and programmable constant temperature and humidity test chambers, all remaining water in the equipment should be drained in a timely manner to avoid freezing and damaging the pipelines, as well as preventing the testing equipment from operating normally.
