Applicable standard
GB 36246-2018 "Sports Fields with Synthetic Surfaces for Primary and Secondary Schools"
T/310101002-C003-2016 "Limits of Hazardous Substances in Plastic Surfaces of School Sports Grounds"
ASTM D 5116-97 "Standard Guide for Small-Scale Environmental Chambers for Determination of Organic Emissions from Indoor Materials and Products"
ASTM D 6007-02 "Standard Test Method for Determination of Formaldehyde Concentration in Air Released from Wood Products by Small Environmental Chamber"

product structure
From the outside to the inside of the test box are: insulation shell, constant temperature room, combined working warehouse, equipment warehouse, etc.
1) Insulation shell: metal shell, filled with polyurethane and other heat insulating materials inside, good heat insulation to prevent energy loss in the Test Chamber, and at the same time isolate the impact of the environment on the working chamber to ensure the smooth operation of the equipment.
2) Constant temperature room: the sealed space formed by the thermal insulation shell, the working cabin is placed in it, and the temperature is indirectly controlled by controlling the temperature of the air.
3) Working cabin: It is made of inert and mirror-finished stainless steel with smooth inner wall, and the cabin has good airtightness. It is sealed with clean materials such as expanded polytetrafluoroethylene, and maintains a certain slight positive pressure to prevent the entry of external pollution.
4) Equipment warehouse: place monitoring devices, temperature control devices, humidity control devices, air supply components, filtration and purification systems, circuit devices, etc.
system protection
①High temperature protection in the cabin
②Power overload, leakage, phase loss, underVoltage, overVoltage, phase sequence protection
③ Refrigeration system high-low pressure protection, overload protection
④Heating component overheating protection
⑤Motor overcurrent protection
⑥Fan, air pump overheating, overload protection
⑦Humidification and water shortage protection
⑧Pressure protection
