The HAST (High Voltage Accelerated Aging) environmental test chamber has strict requirements for the installation site, which need to be comprehensively considered from multiple aspects such as environment, space, ground, power supply, water source, and safety. The specific requirements are as follows:

1、 Environmental conditions

1. Temperature and Humidity

• temperature rangeUsually, it is required to control the ambient temperature within10℃-35℃Between them, the optimal range is15℃-28℃Excessive temperature will increase the burden on the refrigeration system of the equipment and reduce the dehumidification efficiency; Low temperature may cause internal icing and damage to pipelines.

• humidity controlThe relative humidity should not exceed85%RHTo avoid high humidity interfering with the accuracy of internal humidity control of the equipment.

• special scenarioIf the equipment does not work for a long time, the ambient temperature should be maintained at5℃-35℃When the temperature is below 5 ℃, residual water in the equipment should be drained to prevent pipeline freezing and cracking.

2. Ventilation and Cleaning

• The installation site needs to be well ventilated to avoid poor equipment heat dissipation or air pollution.

• The surrounding air must not contain flammable, explosive, corrosive gases or high concentration dust to prevent equipment damage or safety accidents.

3. Light and heat sources

• The equipment should avoid direct sunlight and be kept away from heat sources such as heating equipment and heating instruments to prevent the increase in shell temperature from affecting internal temperature control.

4. Vibration and Radiation

• The site should be free of strong vibration sources and strong electromagnetic radiation sources to ensure the normal operation of equipment and accurate test results.

2、 Space requirements

1. Operation and maintenance space

• At least reserve space around the equipment50cmThe ventilation space is convenient for heat dissipation and daily maintenance.

• Normal opening and closing space should be left at the unboxing door to ensure convenient operation.

2. Handling and installation space

• If the equipment is placed on the first floor, it is necessary to confirm whether the dimensions of the entrance passage and corridor meet the handling requirements.

• If placed on the second floor or above, the size and load-bearing capacity of the cargo elevator need to be checked. If they do not meet the requirements, lifting methods should be used.

3、 Ground requirements

1. Flatness and load-bearing capacity

• The ground should be flat and sturdy, with a load-bearing capacity of not less than800 kilograms per square meterEnsure that the equipment is placed smoothly without shaking.

2. drainage facilities

• Drainage floor drains should be installed near the site to facilitate equipment drainage and avoid water accumulation affecting operation.

4、 Power supply requirements

1. Power type and voltage

• Usually equipped withThree phase five wire power supply(380V) orSingle phase power supply（220V）， Please refer to the equipment nameplate for details.

• The voltage fluctuation range should be controlled within the rated voltage± 5% to ± 10%Within, avoid unstable voltage and damage to equipment.

2. grounding protection

• Must have a reliable grounding device, with a grounding resistance not exceeding4ΩTo prevent safety accidents caused by static electricity or leakage.

5、 Water source requirements (if humidification function is required)

1. water quality requirements

• Recommended to useDistilled water or RO waterReduce the damage of scale to equipment and extend its service life.

2. Water source connection

• There should be a water source interface near the equipment to ensure the normal operation of the humidification system.

6、 Safety requirements

1. Safety device inspection

• Before installation, it is necessary to check whether the safety devices such as over temperature protection, over voltage protection, and leakage protection are working properly, to ensure that the power can be cut off or the test can be stopped in a timely manner in case of abnormalities.

2. Operational Security

• Operators need to wear protective gloves to avoid harm to the human body caused by high temperature and high humidity environments.

• After the experiment is completed, the equipment needs to be cleaned to remove residual water vapor and impurities, and to maintain internal cleanliness.
