The outer box is formed by CNC machine tools, and the outer shell is formed by high-quality cold-rolled steel plate, and the surface is electrostatically sprayed after pickling and phosphate treatment;
Door and door buckle:
The door seal adopts double-layer refined silicon rubber, so that there is no aging and hardening phenomenon under high and low temperature conditions, and the sealing is more reliable;
The test box is a single door (embedded door handle), with a non-reactional handle;
The door is equipped with an observation window, anti-frost device and switchable lighting lamp;
Size: 25 cm W × 30 cm H;
Radiation-proof hollow glass observation window;
The electric control part of the test box:
This part is the core part of the test chamber;
The main switch of the power supply is an air pressure switch, which controls the overall circuit part;
All line parts have strict line markings for easy maintenance;
Safety protection measures for the electronic control part: When the control system detects the following protection devices (single row), it should be able to automatically cut off the whole system and give an alarm;

Working part of the test chamber: Compressor condensation part:
Refrigeration system: The core of the refrigeration system is the compressor. In this solution, we use 2 French Taikang fully enclosed compressors to ensure the cooling requirements of the studio.
The design of the refrigeration system applies energy adjustment technology. An effective treatment method can ensure that the energy consumption and cooling capacity of the refrigeration system can be adjusted under the normal operation of the refrigeration unit, so that the operation cost and failure of the refrigeration system The rate dropped to a more economical state.
Refrigeration evaporator: The evaporator is located in the interlayer of the air duct at one end of the test box, and it is forced to ventilate by a blower motor to quickly exchange heat.
Refrigeration system cooling method: forced air cooling;
Refrigerant: R404a; (environmental friendly refrigerant)
Heating part: Heating: Direct heating in the test box;
The military-grade stainless steel finned heating tube is adopted, and the heating rate is stable, which can keep the temperature in the box without sharp changes. It has the advantages of corrosion resistance, high and low temperature resistance, no leakage, and easy installation; Using SSR (solid state relay) output control, it has the advantages of no noise, reliable work, long life, strong anti-interference ability, fast switching speed, small external interference, and convenient use;
Rain shower system:
The rain shower system is mainly composed of nozzles, solenoid valves, water supply sources and connecting hoses.
